Medical Assistant Health Coaching for Type 2 Diabetes in Primary Care: Results From a Pragmatic Cluster Randomized Controlled Trial

OBJECTIVE

This cluster (clinic-level) randomized controlled trial (RCT) compared medical assistant (MA) health coaching (MAC) with usual care (UC) among at-risk adults with type 2 diabetes in two diverse real-world primary care environments: a federally qualified health center (FQHC; Neighborhood Healthcare) and a large nonprofit private insurance-based health system (Scripps Health).

RESEARCH DESIGN AND METHODS

A total of 600 adults with type 2 diabetes who met one or more of the following criteria in the last 90 days were enrolled: HbA1c ≥8% and/or LDL cholesterol ≥100 mg/dL and/or systolic blood pressure (SBP) ≥140 mmHg. Participants at MAC clinics received in-person and telephone self-management support from a specially trained MA health coach for 12 months. Electronic medical records were used to examine clinical outcomes in the overall sample. Behavioral and psychosocial outcomes were evaluated in a subsample (n = 300).

RESULTS

All clinical outcomes improved significantly over 1 year in the overall sample (P < 0.001). The reduction in HbA1c was significantly greater in the MAC versus UC group (unstandardized Binteraction = -0.06; P = 0.002). A significant time by group by site interaction also showed that MAC resulted in greater improvements in LDL cholesterol than UC at Neighborhood Healthcare relative to Scripps Health (Binteraction = -1.78 vs. 1.49; P < 0.05). No other statistically significant effects were observed.

CONCLUSIONS

This was the first large-scale pragmatic RCT supporting the real-world effectiveness of MAC for type 2 diabetes in U.S. primary care settings. Findings suggest that this team-based approach may be particularly effective in improving diabetes outcomes in FQHC settings.

Association of multiple metabolic and cardiovascular markers with the risk of cognitive decline and mortality in adults with Alzheimer's disease and AD-related dementia or cognitive decline: a prospective cohort study

Background and objectives

There is a scarcity of data stemming from large-scale epidemiological longitudinal studies focusing on potentially preventable and controllable risk factors for Alzheimer's disease (AD) and AD-related dementia (ADRD). This study aimed to examine the effect of multiple metabolic factors and cardiovascular disorders on the risk of cognitive decline and AD/ADRD.

Methods

We analyzed a cohort of 6,440 participants aged 45-84 years at baseline. Multiple metabolic and cardiovascular disorder factors included the five components of the metabolic syndrome [waist circumference, high blood pressure (HBP), elevated glucose and triglyceride (TG) concentrations, and reduced high-density lipoprotein cholesterol (HDL-C) concentrations], C-reactive protein (CRP), fibrinogen, interleukin-6 (IL-6), factor VIII, D-dimer, and homocysteine concentrations, carotid intimal-medial thickness (CIMT), and urine albumin-to-creatinine ratio (ACR). Cognitive decline was defined using the Cognitive Abilities Screening Instrument (CASI) score, and AD/ADRD cases were classified using clinical diagnoses.

Results

Over an average follow-up period of 13 years, HBP and elevated glucose, CRP, homocysteine, IL-6, and ACR concentrations were significantly associated with the risk of mortality in the individuals with incident AD/ADRD or cognitive decline. Elevated D-dimer and homocysteine concentrations, as well as elevated ACR were significantly associated with incident AD/ADRD. Elevated homocysteine and ACR were significantly associated with cognitive decline. A dose-response association was observed, indicating that an increased number of exposures to multiple risk factors corresponded to a higher risk of mortality in individuals with cognitive decline or with AD/ADRD.

Conclusion

Findings from our study reaffirm the significance of preventable and controllable factors, including HBP, hyperglycemia, elevated CRP, D-dimer, and homocysteine concentrations, as well as, ACR, as potential risk factors for cognitive decline and AD/ADRD.

The Role of Cilostazol, a Phosphodiesterase-3 Inhibitor, in the Development of Atherosclerosis and Vascular Biology: A Review with Meta-Analysis

Atherosclerotic cardiovascular disease (ASCVD) stands as the leading global cause of mortality. Addressing this vital and pervasive condition requires a multifaceted approach, in which antiplatelet intervention plays a pivotal role, together with antihypertensive, antidiabetic, and lipid-lowering therapies. Among the antiplatelet agents available currently, cilostazol, a phosphodiesterase-3 inhibitor, offers a spectrum of pharmacological effects. These encompass vasodilation, the impediment of platelet activation and aggregation, thrombosis inhibition, limb blood flow augmentation, lipid profile enhancement through triglyceride reduction and high-density lipoprotein cholesterol elevation, and the suppression of vascular smooth muscle cell proliferation. However, the role of cilostazol has not been clearly documented in many guidelines for ASCVD. We comprehensively reviewed the cardiovascular effects of cilostazol within randomized clinical trials that compared it to control or active agents and involved individuals with previous coronary artery disease or stroke, as well as those with no previous history of such conditions. Our approach demonstrated that the administration of cilostazol effectively reduced adverse cardiovascular events, although there was less evidence regarding its impact on myocardial infarction. Most studies have consistently reported its favorable effects in reducing intermittent claudication and enhancing ambulatory capacity in patients with peripheral arterial disease. Furthermore, cilostazol has shown promise in mitigating restenosis following coronary stent implantation in patients with acute coronary syndrome. While research from more diverse regions is still needed, our findings shed light on the broader implications of cilostazol in the context of atherosclerosis and vascular biology, particularly for individuals at high risk of ASCVD.

Unraveling atherosclerotic cardiovascular disease risk factors through conditional probability analysis with Bayesian networks: insights from the AZAR cohort study

This study aimed at modelling the underlying predictor of ASCVD through the Bayesian network (BN). Data for the AZAR Cohort Study, which evaluated 500 healthcare providers in Iran, was collected through examinations, and blood samples. Two BNs were used to explore a suitable causal model for analysing the underlying predictor of ASCVD; Bayesian search through an algorithmic approach and knowledge-based BNs. Results showed significant differences in ASCVD risk factors across background variables' levels. The diagnostic indices showed better performance for the knowledge-based BN (Area under ROC curve (AUC) = 0.78, Accuracy = 76.6, Sensitivity = 62.5, Negative predictive value (NPV) = 96.0, Negative Likelihood Ratio (LR-) = 0.48) compared to Bayesian search (AUC = 0.76, Accuracy = 72.4, Sensitivity = 17.5, NPV = 93.2, LR- = 0.83). In addition, we decided on knowledge-based BN because of the interpretability of the relationships. Based on this BN, being male (conditional probability = 63.7), age over 45 (36.3), overweight (51.5), Mets (23.8), diabetes (8.3), smoking (10.6), hypertension (12.1), high T-C (28.5), high LDL-C (23.9), FBS (12.1), and TG (25.9) levels were associated with higher ASCVD risk. Low and normal HDL-C levels also had higher ASCVD risk (35.3 and 37.4), while high HDL-C levels had lower risk (27.3). In conclusion, BN demonstrated that ASCVD was significantly associated with certain risk factors including being older and overweight male, having a history of Mets, diabetes, hypertension, having high levels of T-C, LDL-C, FBS, and TG, but Low and normal HDL-C and being a smoker. The study may provide valuable insights for developing effective prevention strategies for ASCVD in Iran.

Non-high-density lipoprotein cholesterol and treatment targets in vascular surgery patients

INTRODUCTION

Low-density lipoprotein cholesterol (LDL) is a known contributing factor to atherosclerotic cardiovascular disease (ASCVD) and a primary therapeutic target for medical management of ASCVD. Non-high-density lipoprotein cholesterol (non-HDL) has recently been identified as a secondary therapeutic target but is not yet widely used in vascular surgery patients. We sought to assess if vascular surgery patients were undertreated per non-HDL therapeutic guidelines.

METHODS

This was an observational study that used a single-center database to identify a cohort of adult patients who received care from a vascular surgery provider from 01/2001 to 07/2021. ICD-9/10-CM codes were used to identify patients with a medical history of hyperlipidemia (HLD), coronary artery disease (CAD), cerebrovascular occlusive disease (CVOD), peripheral artery disease (PAD), hypertension (HTN), or diabetes mellitus (DM). Patient smoking status and medications were also identified. Lab values were obtained from the first and last patient encounter within our system. Primary outcomes were serum concentrations of LDL and non-HDL, with therapeutic thresholds defined as 70 mg/dL and 100 mg/dL, respectively.

RESULTS

The cohort included 2465 patients. At first encounter, average age was 59.3 years old, 21.4% were on statins, 8.4% were on a high-intensity statin, 25.7% were diagnosed with HLD, 5.2% with CAD, 15.3% with PAD, 26.3% with DM, 18.6% with HTN, and 2.1% with CVOD. At final encounter, mean age was 64.8 years, 23.5% were on statins with 10.1% on high-intensity statin. Diagnoses frequency did not change at final encounter. At first encounter, nearly two-thirds of patients were not at an LDL <70 mg/dL (62.3%) or non-HDL <100 mg/dL (66.0%) with improvement at final encounter to 45.2 and 40.5% of patients not at these LDL or non-HDL treatment thresholds, respectively. Patients on statins exhibited similar trends with 51.1 and 50.1% of patients not at LDL or non-HDL treatment thresholds at first encounter and 39.9 and 35.4% not at LDL or non-HDL treatment thresholds at last encounter. Importantly, 6.9% of patients were at LDL but not non-HDL treatment thresholds.

DISCUSSION

Among vascular surgery patients, over half did not meet non-HDL targets. These results suggest that we may be vastly under-performing adequate medical optimization with only about one-fourth of patients on a statin at their final encounter and approximately one-tenth of patients being treated with a high-intensity statin. With recent evidence supporting non-HDL as a valuable measurement for atherosclerotic risk, there is potential to optimize medical management beyond current high-intensity statin therapy. Further investigation is needed regarding the risk of adverse events between patients treated with these varied therapeutic targets.

Diabetic Vasculopathy: Molecular Mechanisms and Clinical Insights

Clinical and basic studies have documented that both hyperglycemia and insulin-resistance/hyperinsulinemia not only constitute metabolic disorders contributing to cardiometabolic syndrome, but also predispose to diabetic vasculopathy, which refers to diabetes-mellitus-induced microvascular and macrovascular complications, including retinopathy, neuropathy, atherosclerosis, coronary artery disease, hypertension, and peripheral artery disease. The underlying molecular and cellular mechanisms include inappropriate activation of the renin angiotensin-aldosterone system, mitochondrial dysfunction, excessive oxidative stress, inflammation, dyslipidemia, and thrombosis. These abnormalities collectively promote metabolic disorders and further promote diabetic vasculopathy. Recent evidence has revealed that endothelial progenitor cell dysfunction, gut dysbiosis, and the abnormal release of extracellular vesicles and their carried microRNAs also contribute to the development and progression of diabetic vasculopathy. Therefore, clinical control and treatment of diabetes mellitus, as well as the development of novel therapeutic strategies are crucial in preventing cardiometabolic syndrome and related diabetic vasculopathy. The present review focuses on the relationship between insulin resistance and diabetes mellitus in diabetic vasculopathy and related cardiovascular disease, highlighting epidemiology and clinical characteristics, pathophysiology, and molecular mechanisms, as well as management strategies.

Rationale and design for the Blood Pressure Control Target in Diabetes (BPROAD) study

BACKGROUND

Diabetes and hypertension are major modifiable risk factors for cardiovascular disease. Previous clinical trials have demonstrated that intensive blood pressure reduction lowers the risk of cardiovascular disease and all-cause mortality compared to standard blood pressure reduction among patients without diabetes. However, optimal levels of blood pressure control in patients with diabetes remain uncertain.

METHODS

The Blood Pressure Control Target in Diabetes (BPROAD) study is a multicenter, randomized controlled trial conducted in mainland China. We plan to enroll 12 702 participants aged ≥50 years with type 2 diabetes, an increased cardiovascular risk, and systolic blood pressure ≥130 mm Hg from 150 study centers. Participants are randomly assigned to intensive (a systolic target of <120 mm Hg) or standard (a systolic target of <140 mm Hg) blood pressure treatment group. Participants will be followed monthly for blood pressure management in the first 3 months and then every 3 months afterward. The primary study outcome is a composite of major cardiovascular events including nonfatal myocardial infarction, nonfatal stroke, treated or hospitalized heart failure, and cardiovascular death. Data will be collected every 3 months for up to 5 years and a blinded outcome committee will adjudicate all clinical outcomes. The BPROAD study is designed to have 90% statistical power to detect a 20% reduction in the primary study outcome at a two-sided significance level of 0.05.

CONCLUSIONS

The BPROAD study will provide important evidence as to whether intensive blood pressure management has additional benefits on cardiovascular disease and all-cause mortality among patients with type 2 diabetes.

Association between endothelial biomarkers and lipid and glycemic levels: a cross-sectional study with diabetic patients

Background: Biomarkers can help understand the impact of achieving therapeutic goals in developing vascular diseases in diabetics. Aim: To assess the association between lipid and glycemic profiles and endothelial biomarkers in diabetics. Methods: Cross-sectional study that evaluated lipid and glycemic levels and biomarkers (VCAM-1, Sdc-1, FGF-23 and KIM-1 in diabetics. Results: Higher VCAM-1 levels were associated with higher low-density lipoprotein cholesterol and non-high-density lipoprotein (HDL) cholesterol levels (in the group with inadequate glycohemoglobin A1c [HbA1c] levels), with higher glycemic levels (in the group with inadequate HDL cholesterol levels) and with lower HDL cholesterol levels (both groups). VCAM-1 was independently associated with not achieving adequate HbA1c levels. Conclusion: In uncontrolled diabetics, VCAM-1 was independently associated with having inadequate HbA1c levels, suggesting they may already have endothelial damage.

Machine learning framework for atherosclerotic cardiovascular disease risk assessment

Introduction

Atherosclerotic cardiovascular disease (ASCVD) is the first leading cause of mortality globally. To identify the individual risk factors of ASCVD utilizing the machine learning (ML) approaches.

Materials & methods

This cohort-based cross-sectional study was conducted on data of 500 participants with ASCVD among Tabriz University Medical Sciences employees, during 2020. The data with ML methods were developed and validated to predict ASCVD risk with naive Bayes (NB), spurt vesture machines (SVM), regression tree (RT), k-nearest neighbors (KNN), artificial neural networks (ANN), generalized additive models (GAM), and logistic regression (LR).

Results

Accuracy of the models ranged from 95.7 to 98.1%, with a sensitivity of 50.0 to 97.3%, specificity of 74.3 to 99.1%, positive predictive value (PPV) of 0.0 to 98.0%, negative predictive value (NPV) of 68.4 to 100.0%, positive likelihood ratio (LR +) of 13.8 to 96.4%, negative likelihood ratio (LR-) of 3.6 to 51.9%, and area under ROC curve (AUC) of 62.5 to 99.4%. The ANN fit the data best with an accuracy of 98.1% (95% CI: 96.5-99.1), a specificity of 99.1% (95% CI: 97.7-99.9), a LR + of 96.4% (95% CI: 36.2-258.8), and AUC of 99.4% (95% CI: 85.2-97.0). Based on the optimal model, sex (females), age, smoking, and metabolic syndrome were shown to be the most important risk factors of ASCVD.

Conclusion

Sex (females), age, smoking, and metabolic syndrome were predictors obtained by ANN. Considering the ANN as the optimal model identified, more accurate prevention planning may be designed.

Inflammatory and metabolic markers and comorbidities remission following sleeve gastrectomy: A single center one-year cohort study

BACKGROUND AND AIM

Obesity is a global concern with several health-related complications. Bariatric surgeries are major treatment options in patients with obesity and other comorbidities. This study aims to investigate the effects of sleeve gastrectomy on metabolic indexes, hyperechogenic liver changes, inflammatory state, diabetes, and other obesity-related comorbidities remission after the sleeve gastrectomy.

METHODS

This prospective study was conducted on patients with obesity candidates for laparoscopic sleeve gastrectomy. Patients were followed for one year after the surgery. Comorbidities, metabolic and inflammatory parameters were assessed before and one- year after the surgery.

RESULTS

137 patients (16 males, 44 in the DM group) underwent sleeve gastrectomy. One year after the study, obesity-related comorbidities improved significantly; diabetes had complete remission in 22.7% and partial remission in 63.6% of patients. Hyper-cholesterolemia, hyper-triglyceridemia, and hyper-uricemia also improved in 45.6%, 91.2%, and 69% of the patients. Metabolic syndrome indexes improved in 17.5% of the patients. Also, the prevalence of hyperechogenic changes in the liver has declined from 21% before the surgery to 1.5% after that. Based on logistic regression analysis, increased levels of HbA1C reduced the chance of diabetes remission by 0.9%. In comparison, every unit of increased BMI before the surgery improved the case of diabetes remission by 16%.

CONCLUSION

Laparoscopic sleeve gastrectomy is a safe and effective treatment option in patients with obesity and diabetes. Laparoscopic sleeve gastrectomy alleviates BMI and insulin resistance and effectively improves other obesity-related comorbidities such as Hypercholesterolemia, hyper-triglyceridemia, hyper-uricemia, and hyperechogenic changes of the liver. HbA1C and BMI before the surgery are notable predictors of diabetes remission within the first year after the surgery.

Transportation-related Environmental Mixtures and Diabetes Prevalence and Control in Urban/Metropolitan Counties in the United States

Diabetes rates in the United States are staggering and climbing. Importantly, traditional risk factors fail to completely account for the magnitude of the diabetes epidemic. Environmental exposures, including urban and metropolitan transportation quality, are implicated as contributors to disease. Using data from the county-level Environmental Quality Index (EQI) developed for the United States, we analyzed associations between transportation and air quality environmental metrics with overall diabetes prevalence and control within urban/metropolitan counties in the United States from 2006 to 2012. Additionally, we examined effect modification by race/ethnicity through stratification based on the county-level proportion of minority residents. Last, we applied mixture methods to evaluate the effect of simultaneous poor transportation factors and worse air quality on the same outcomes. We found that increased county-level particulate matter air pollution and nitrogen dioxide along with reduced public transportation usage and lower walkability were all associated with increased diabetes prevalence. The minority proportion of the population influences some of these relationships as some of the effects of air pollution and the transportation-related environment are worse among counties with more minority residents. Furthermore, the transportation and air quality mixtures were found to be associated with increased diabetes prevalence and reduced diabetes control. These data further support the burgeoning evidence that poor environments amplify diabetes risk. Future cohort studies should explore the utility of environmental policies and urban planning as tools for improving metabolic health.

Is Triglyceride-Glucose Index a Valuable Parameter in Peripheral Artery Disease?

Background The aim of this study was to investigate the relationship between the triglyceride-glucose (TyG) index and peripheral artery disease. Methodology This was a single-center, observational, retrospective study that included patients evaluated with color Doppler ultrasonography. A total of 440 individuals, 211 peripheral artery patients and 229 healthy controls, were included in the study. Results The TyG index levels were significantly higher in the peripheral artery disease group than in the control group (9.19 ± 0.57 vs. 8.80 ± 0.59; p < 0.001). The multivariate regression analysis conducted to determine the independent predictors of peripheral artery disease revealed that age (odds ratio (OR) = 1.111, 95% confidence interval (CI) = 1.083-1.139; p < 0.001), male gender (OR = 0.441, 95% CI = 0.249-0.782; p = 0.005), diabetes mellitus (OR = 1.925, 95% CI = 1.018-3.641; p = 0.044), hypertension (OR = 0.036, 95% CI = 0.285- 0.959; p = 0.036), coronary artery disease (OR = 2.540, 95% CI = 1.376-4.690; p = 0.003), white blood cell count (OR = 1.263, 95% CI = 1.029-1.550; p = 0.026), creatinine (OR = 0.975, 95% CI = 0.952-0.999; p = 0.041), and TyG index (OR = 1.111, 95% CI = 1.083-1.139; p < 0.001) were independent predictors of peripheral artery disease. The cut-off value of the TyG index in predicting peripheral artery disease was determined to be 9.06 with a sensitivity of 57.8% and a specificity of 70% (area under the curve = 0.689; 95% CI = 0.640-0.738; p < 0.001). Conclusions High TyG index values can be used as an independent predictor of peripheral artery disease.

The Effect of Clinically Indicated Liraglutide on Pericoronary Adipose Tissue in Type 2 Diabetic Patients

Vascular inflammation can be detected in the pericoronary adipose tissue (PCAT) by coronary computed tomography angiography (CCTA) attenuation. Treatment with liraglutide is associated with anti-inflammatory effects and reduces cardiovascular risk in diabetic patients. This study is aimed at examining the effect of clinically indicated liraglutide on PCAT attenuation. Asymptomatic patients with type 2 diabetes mellitus (T2DM) and without known ischemic heart disease underwent clinical examination, blood analysis, and CCTA. The main coronary arteries were outlined and PCAT attenuation was measured on the proximal 40 mm. Patients treated with liraglutide on a clinical indication were compared to patients not receiving liraglutide. The study included 190 patients; 53 (28%) received liraglutide (Lira+) and 137 (72%) did not (Lira-). There were no significant differences in PCAT attenuation between the two groups in either artery. However, PCAT attenuation measured around the left anterior descending artery (LAD) was lower in the Lira+ group after adjustment for age, sex, body mass index, and T2DM duration (b coefficient -2.4, p = 0.029). In a population of cardiac asymptomatic T2DM patients, treatment with clinically indicated liraglutide was not associated with differences in PCAT attenuation compared to nonliraglutide treatment in the unadjusted model. An association was seen in the adjusted model for the left anterior descending artery, possibly indicating an anti-inflammatory effect.

Applying the Theory of Planned Behavior to predict community pharmacists' intention to provide diabetes care

BACKGROUND

The role of the pharmacist has changed from dispensing medicines, to working with other healthcare professionals to assure appropriate medication therapy management. This study assessed community pharmacists' intention regarding diabetes care based on the theory of planned behavior (TPB) in Alexandria, Egypt.

METHODS

A sample of 385 community pharmacies with one index per site (one pharmacist per pharmacy) was recruited in the sample using a multistage random sampling technique. This cross-sectional survey was performed using a self-administered questionnaire that measured the constructs of TPB. A structural equation model was used to identify specific factors that most contribute to and predict pharmacists' intention to provide diabetes care.

RESULTS

The sample included 385 pharmacies, approximately half of them (51.4%) were males and the majority of them (94%) had a bachelor's degree in pharmaceutical sciences. Intention was significantly correlated with attitude, subjective norm and perceived behavioral control. "Regular screening for complications can improve quality of life for diabetic patients" (β = 1.131) was the most specific factor motivating pharmacists to perform diabetes care, while "some physicians do not appreciate pharmacists' involvement in diabetic care" was the most specific factor that negatively influenced intention of pharmacists to provide diabetes care (β = 4.283).

CONCLUSION

Community pharmacists demonstrated a positive attitude, perceived significant approval from others and felt able to intervene in diabetes care. However, lack of physician collaboration was a specific hindering factor for pharmacists' practice of diabetes care.

Adherence of physicians to evidence-based management guidelines for treating type 2 diabetes and atherosclerotic cardiovascular disease in Ajman, United Arab Emirates

Background

Good adherence by physicians to treatment guidelines for type II diabetes mellitus (T2DM) could improve therapy outcome for patients. In this retrospective, cross-sectional study, we assessed physicians’ adherence to evidence-based guidelines for T2DM management in adult patients (aged ≥18 years) with either confirmed atherosclerotic cardiovascular disease (ASCVD) or those at high risk of developing ASCVD at the Thumbay Academic Health Center, United Arab Emirates (UAE).

Methods

Relevant data was obtained from patients’ medical records, assessed, and compared based on the 2018 diabetes guidelines of the American Diabetes Association and European Association for the Study of Diabetes.

Results

A total of 218 patients (186 males and 32 females) were included in the analysis. Of these, 122 were prescribed either sodium-glucose co-transporter-2(SGLT2) inhibitors or glucagon-like peptide 1 (GLP-1) receptor agonists and 34 were prescribed both. The overall adherence to the guidelines was 56%, which was significantly influenced by body mass index (BMI), hemoglobin A1c (HbA1c) levels, and estimated average glucose (eAG).

Conclusions

Adherence to guidelines was significantly high when treating patients with elevated levels of HbA1c and eAG, suggesting that physicians are more likely to prescribe SGLT2 inhibitors or/and GLP-1 receptor agonists to such patients. Physicians’ adherence to guidelines was significantly correlated with patients’ BMI and the levels of HbA1c and eAG. To the best of our knowledge, this is the first study conducted on diabetes and its risk factors in UAE.

The effect of telemedicine on secondary prevention of atherosclerotic cardiovascular disease: A systematic review and meta-analysis

Aim

The purpose of this systematic review was to evaluate the efficiency of telemedicine on the secondary level of prevention of patients with arteriosclerotic cardiovascular disease (ASCVD), provide evidence for the application of telemedicine in secondary prevention and promote the development of telemedicine in secondary prevention.

Methods

A computer-based search was conducted in MEDLINE, Embase, Pubmed, EBSCO, CINAHL, the Cochrane Library, and Web of Science. Randomized controlled trials regarding the effect of telemedicine on secondary prevention of ASCVD were included from inception to May, 2022. Meta-analysis was used to compare the results of the included studies by RevMan5.4 software. The Cochrane Collaboration bias risk tool was used to perform risk of bias assessment in this study. Outcomes included risk factors, physical activity and exercise, muscle function, exercise compliance, medication adherence, healthy diet, depression and anxiety, self-efficacy, knowledge score, economy, and safety endpoints. Subgroup analysis was carried out for different main intervention measures included in the literature.

Results

A total of 32 randomized clinical studies (n = 10 997 participants) were included in the meta-analysis. Compared with usual secondary prevention (USP) group, participants in telemedicine of secondary prevention (TOSP) group showed significant improvement in some risk factors including BMI (MD –0.87, p = 0.002), SBP (MD –4.09, p = 0.007) and DBP (MD –2.91, p = 0.0002) when they use the telephone as the intervention. In physical activity and exercise, Patients in TOSP showed an improvement in VO2 Peak (mL⋅kg–1⋅min–1) (OR 1.58, p = 0.02), 6MWT (MD 21.41, p = 0.001), GSLTPA score (MD 2.89, p = 0.005). Effects on medication adherence, exercise compliance, muscle function, healthy diet, economy and self-efficacy were synthesized narratively. Patients in TOSP did not show a reduction in knowledge score, depression, anxiety and safety endpoints.

Conclusion

There is a net benefit of secondary prevention supported by telemedicine (especially when using the telephone as an intervention) in patients with ASCVD in the terms of some risk factors, physical activity and exercise. There are still controversies in the improvement of medication adherence, exercise compliance, muscle function, healthy diet, knowledge score, self-efficacy and economy via telemedicine, which is worth exploring. Larger samples size and longer-term follow-ups are needed in future studies.

Masked nocturnal hypertension as a result of high prevalence of non-dippers among apparently well-controlled hypertensive patients with type 2 diabetes mellitus: data from a prospective study

BACKGROUND

Ambulatory blood pressure monitoring (ABPM) in patients with diabetes mellitus (DM) and hypertension (HTN) show the dipping patterns, identify masked uncontrolled hypertension (MUCH), and demonstrate the effectiveness of the blood pressure (BP) treatment. MUCH is associated with a two-fold higher risk of adverse events. Prevalence in patients with DM is between 13.3 and 66.4%. Our study aims to investigate the prevalence of MUCH and the BP patterns in a population of apparently well-controlled hypertensive patients with type 2 DM (T2DM). A second aspect was the assessment of the effectiveness of antihypertensive treatment.

METHODS

One hundred and sixty-three consecutively treated hypertensive patients with T2DM and an office BP between 130-139 and 80-89 mmHg performed a 24 h ABPM. The circadian BP variation, the presence of MUCH, and the correlations with the treatment were assessed.

RESULTS

There were 75 dippers (46.02%), 77 non-dippers (47.23%), 4 reverse dippers (2.45%), and 7 extreme dippers (4.30%). Eighty-one patients (77 non-dippers + 4 reverse dippers; 49.7%) had isolated nocturnal MUCH according to the mean night ABPM criteria. Dippers and extreme dippers (75 dippers + 7 extreme dippers; 51.3%) did not have any MUCH criteria. The patients took, on an average, 3 antihypertensive drugs with no difference between those with controlled HTN and the isolated nocturnal MUCH group. Significant factors associated with isolated nocturnal MUCH and a non-dipping BP pattern included age > 65 years (OR = 1.9), DM duration > 10 years (OR = 1.4), HTN duration > 6.5 years (OR = 1.2), obesity (OR = 1.6), and cardiovascular comorbidities (OR = 1.4).

CONCLUSIONS

The current study shows that half of the treated hypertensive patients with T2DM and office clinical normotension are non-dippers or reverse dippers. They experience isolated nocturnal MUCH due to their elevated nocturnal BP values, which comply with the actual definition of masked nocturnal hypertension. Bedtime chronotherapy in those patients could be linked to better effectiveness of antihypertensive treatment during the night with the important goal of reducing cardiovascular and cerebrovascular adverse events. ABPM should be performed in hypertensive patients with DM for better risk stratification and more effective control of HTN.

National Trends in the Achievement of Recommended Strategies for Stroke Prevention in U.S. Adults With Type 2 Diabetes, 2001-2018

OBJECTIVE

To assess the national prevalence of and trends in achieving current guideline-recommended treatment goals and pharmacotherapies for primary and secondary prevention of stroke among U.S. adults with type 2 diabetes (T2D).

RESEARCH DESIGN AND METHODS

We performed serial cross-sectional analyses in 4,834 adults aged ≥45 years with T2D who participated in the 2001-2018 National Health and Nutrition Examination Survey. With stratification by stroke history, we estimated the proportion of adults with T2D who achieved current guideline-recommended strategies for stroke prevention. Preventive strategies for stroke were benchmarked against diabetes care and cardiovascular risk reduction guidelines.

RESULTS

Overall in 2001-2018, among those without stroke history, the proportion who achieved primary stroke prevention strategies ranged from 8.4% (95% CI 6.8-10.1) for aspirin/clopidogrel treatment in those with a higher cardiovascular disease risk to 80.5% (78.8-82.2) for nonsmoking. Among those with stroke history, the proportion who achieved secondary stroke prevention strategies ranged from 11.8% (8.7-14.8) for weight control to 80.0% (74.9-84.9) for glycemic control. From 2001 to 2018, among those without stroke history, there was a significant increase in statin therapy (Ptrend < 0.0001), smoking abstinence (Ptrend = 0.01), and ACE inhibitor/angiotensin receptor blocker treatment for hypertension (Ptrend = 0.04) but a substantial decline in weight control (Ptrend < 0.001). Among those with stroke history, only statin therapy (Ptrend = 0.01) increased significantly over time.

CONCLUSIONS

During 2001-2018, the achievement of some current guideline-recommended strategies for stroke prevention among U.S. adults with T2D improved but remains a challenge overall. Efforts are needed to improve implementation of strategies for stroke prevention in this population.

Long-term cost-effectiveness of quality of diabetes care; experiences from private and public diabetes centers in Iran

BACKGROUND

The quality of health care has a significant impact on both patients and the health system in terms of long-term costs and health consequences. This study focuses on determining the long-term cost-effectiveness in quality of diabetes care in two different settings (private/public) using longitudinal patient-level data in Iran.

METHODS

By extracting patients intermediate biomedical markers in under-treatment type 2 diabetes patients(T2DP) in a longitudinal retrospective study and by applying the localized UKPDS diabetes model, lifetime health outcomes including life expectancy, quality-adjusted Life expectancy (QALE) and direct medical costs of managing disease and related complications from a healthcare system perspective was predicted. Costs and utility decrements had derived on under-treatment T2DP from 7 private and 8 Public diabetes centers. We applied two steps sampling mehods to recruit the needed sample size (cluster and random sampling). To cope with first and second-order uncertainty, we used Monte-Carlo simulation and bootstrapping techniques. Both cost and utility variables were discounted by 3% in the base model.

RESULTS

In a 20-year time horizon, according to over 5 years of quality of care data, outcomes-driven in the private sector will be more effective and more costly (5.17 vs. 4.95 QALE and 15,385 vs. 8092). The incremental cost-effectiveness ratio (ICER) was $33,148.02 per QALE gained, which was higher than the national threshold.

CONCLUSION

Although quality of care in private diabetes centers resulted in a slight increase in the life expectancy in T2DM patients, it is associated with unfavorable costs, too. Private-sector in management of T2DM patients, compared with public (governmental) diabetic Centers, is unlikely to be cost-effective in Iran.

Ten-year atherosclerosis cardiovascular disease (ASCVD) risk score and its components among an Iranian population: a cohort-based cross-sectional study

BACKGROUND

Atherosclerotic cardiovascular disease (ASCVD) continues to be the first cause of mortality globally. Effective preventive strategies require focused efforts to clarify ASCVD risk factors in different subgroups of a population. This study aimed to identify individuals at higher risk of ASCVD among Shiraz University employees to guide decision-making for primary prevention.

METHODS

This cohort-based cross-sectional study was conducted on data of 1191 participants (25-70 years old) from Shiraz University employees selected by systematic random sampling. The 10-year ASCVD risk was calculated with an ASCVD risk score estimator developed by the American College of Cardiology/American Heart Association (ACC/AHA). To analyze the data, descriptive and chi-square tests were used. All statistical analyses were conducted using the SPSS version 16.0 software. The p-value < 0.05 was considered a significant level.

RESULTS

This study demonstrated that 75.3% of the participants had low risk scores, whereas 13.2% and 2.5% of them had intermediate and high risk scores, respectively. Additionally, it revealed that among women 93.7%, 2.7%, and 0.6% had low intermediate and had high risk scores, respectively, whereas among men, 61.5%, 21.1%, and 3.9% had low intermediate and high risk scores, respectively. Based on the results of the chi-square test, men were significantly more prone to ASCVD (38.5%) than women (6.3%) were. Interestingly, 40.9% of known cases of hypertension had uncontrolled blood pressure, and 62.5% of individuals without any history of hypertension, who were considered new cases of hypertension, had abnormal blood pressure. Furthermore, 38.5% of diabetic patients and 1.6% of people who did not have a history of diabetes had abnormal serum fasting blood sugar.

CONCLUSION

It was revealed that nearly 15.7% of participants were at intermediate and high risk of developing ASCVD in the next 10 years with greater risk in men. Considerably, some of hypertensive and diabetic participants had uncontrolled blood pressure and blood sugar levels, respectively. New cases of diabetes and hypertension were also recognized in our study. Therefore, to address the primary prevention of ASCVD in this population, it is necessary to have plans for targeted interventions, which can be effective in modifying their risk factors.

Blood pressure targets: comparing lower versus standard targets for people with hypertension

In this commentary, Hamer, Hill and Harrison critically appraise a systematic review comparing lower versus standard targeted blood pressure and how this impacts morbidity and mortality in people with hypertension.

The Role of SGLT2 Inhibitors in Atherosclerosis: A Narrative Mini-Review

Objective: Sodium glucose cotransporter 2 inhibitors (SGLT2-is) are antidiabetic drugs that improve glycemic control by limiting urinary glucose reuptake in the proximal tubule. SGLT2-is might suppress atherosclerotic processes and ameliorate the prognosis of patients with diabetes mellitus diagnosed with or at high risk of atherosclerotic cardiovascular disease (ASCVD). In this mini review, we examine the role of SGLT2-is in the development and progression of atherosclerosis throughout its spectrum, from subclinical atherosclerosis to ASCVD.

Data Sources—PubMed and Google Scholar were searched for publications related to SGLT2-is and atherosclerosis. All types of articles were considered, including clinical trials, animal studies, in vitro observations, and reviews and meta-analyses. Data were examined according to their impact and clinical relevance.

Synopsis of Content—We first review the underlying mechanisms of SGLT2-is on the development and progression of atherosclerosis, including favorable effects on lipid metabolism, reduction of systemic inflammation, and improvement of endothelial function. We then discuss the putative impact of SGLT2-is on the formation, composition, and stability of atherosclerotic plaque. Furthermore, we evaluate the effects of SGLT2-is in subclinical atherosclerosis assessed by carotid intima media thickness and pulse wave velocity. Subsequently, we summarize the effects of SGLT2-is in ASCVD events, including ischemic stroke, angina pectoris, myocardial infarction, revascularization, and peripheral artery disease, as well as major adverse cardiovascular events, cardiovascular mortality, heart failure, and chronic kidney disease. Moreover, we examine factors that could modify the role of SGLT2-is in atherosclerosis, including sex, age, diabetes, glycemic control, ASCVD, and SGLT2-i compounds. Additionally, we propose future directions that can improve our understanding of SGLT2-is and atherosclerosis.

Diabetes, Vascular Aging and Stroke: Old Dogs, New Tricks?

BACKGROUND

Stroke remains a leading cause of death and disability throughout the world. It is well established that Diabetes Mellitus (DM) is a risk factor for stroke, while other risk factors include dyslipidaemia and hypertension. Given that the global prevalence of diabetes steadily increases, the need for adequate glycaemic control and prevention of DM-related cardiovascular events remains a challenge for the medical community. Therefore, a re-examination of the latest data related to this issue is of particular importance.

OBJECTIVE

This review aims to summarise the latest data on the relationship between DM and stroke, including epidemiology, risk factors, pathogenesis, prevention and biomarkers.

METHODS

For this purpose, comprehensive research was performed on the platforms PubMed, Google Scholar and EMBASE with a combination of the following keywords: diabetes mellitus, stroke, macrovascular complications, diabetic stroke, cardiovascular disease.

CONCLUSIONS

Much progress has been made in stroke in people with DM in terms of prevention and early diagnosis. In the field of prevention, the adaptation of the daily habits and the regulation of co-morbidity of individuals play a particularly important role. Simultaneously, the most significant revolution has been brought by the relatively new treatment options that offer protection to the cardiovascular system. Moreover, many prognostic and diagnostic biomarkers have been identified, paving the way for early and accurate diagnoses. However, to date, there are crucial points that remain controversial and need further clarification.

Effects of combined treatment with blood flow restriction and low-current electrical stimulation on capillary regression in the soleus muscle of diabetic rats

To clarify the preventive effects of low-current electrical stimulation (ES) under blood flow restriction (Bfr) on diabetes-associated capillary regression in skeletal muscles, we assessed the changes in three-dimensional capillary architecture and angiogenic factors. Twenty-four Goto-Kakizaki rats were randomly divided into four groups: the sedentary diabetes mellitus (DM), Bfr (DM + Bfr), electrical stimulation (DM + ES), and Bfr plus ES (DM + Bfr + ES) groups. Six healthy Wistar rats were used as age-matched controls. Bfr was performed using pressure cuffs (80 mmHg) around the thighs of the rats, and low-current ES was applied to the calf muscles of the rats. The current intensity was set at 30% of the maximal isometric contraction (24-30 mA). The treatments were delivered three times a week for 8 wk. In the DM group, the capillary diameter and volume of the soleus muscle decreased, and, the antiangiogenic factor level increased. Furthermore, DM caused an increase in the hypoxia-inducible factor. Individually, Bfr or ES treatments failed to inhibit the DM-associated capillary regression and increase in antiangiogenic factor. However, combined treatment with Bfr and ES prevented DM-associated capillary regression via inhibition of the increased antiangiogenic factor and enhancement of interleukin-15 expression, mitochondrial biogenesis factors, and a proangiogenic factor. Therefore, DM-associated capillary regression inhibited by the combined treatment may prevent the effects of the increased antiangiogenic factor and enhance the proangiogenic factor.NEW & NOTEWORTHY The combined treatment of blood flow restriction and low intensity electrical stimulation attenuated type 2 diabetes (T2D)-associated capillary regression in the skeletal muscles. The treatment inhibits the T2D-associated increase in antiangiogenic factors via inhibition of intramuscular chronic hypoxia; it can inhibit intramuscular chronic hypoxia by enhancing proangiogenic factors. These results suggest that the combined treatment may be an effective therapeutic intervention for the prevention of T2D-associated capillary regression in the skeletal muscles.

Age-Specific Associations of Usual Blood Pressure Variability With Cardiovascular Disease and Mortality: 10-Year Diabetes Mellitus Cohort Study

Background

The detrimental effects of increased variability in systolic blood pressure (SBP) on cardiovascular disease (CVD) and mortality risk in patients with diabetes mellitus remains unclear. This study evaluated age‐specific association of usual SBP visit‐to‐visit variability with CVD and mortality in patients with type 2 diabetes mellitus.

Methods and Results

A retrospective cohort study investigated 155 982 patients with diabetes mellitus aged 45 to 84 years without CVD at baseline (2008–2010). Usual SBP variability was estimated using SBP SD obtained from a mixed‐effects model. Age‐specific associations (45–54, 55–64, 65–74, 75–84 years) between usual SBP variability, CVD, and mortality risk were assessed by Cox regression adjusted for patient characteristics. After a median follow‐up of 9.7 years, 49 816 events (including 34 039 CVD events and 29 211 mortalities) were identified. Elevated SBP variability was independently, positively, and log‐linearly associated with higher CVD and mortality risk among all age groups, with no evidence of any threshold effects. The excess CVD and mortality risk per 5 mm Hg increase in SBP variability within the 45 to 54 age group is >3 times higher than the 70 to 79 age group (hazard ratio, 1.66; 95% CI, 1.49–1.85 versus hazard ratio, 1.19; 95% CI, 1.15–1.23). The significant associations remained consistent among all subgroups. Patients with younger age had a higher association of SBP variability with event outcomes.

Conclusions

The findings suggest that SBP visit‐to‐visit variability was strongly associated with CVD and mortality with no evidence of a threshold effect in a population with diabetes mellitus. As well as controlling overall blood pressure levels, SBP visit‐to‐visit variability should be monitored and evaluated in routine practice, in particular for younger patients.

The effect of apple cider vinegar on lipid profiles and glycemic parameters: a systematic review and meta-analysis of randomized clinical trials

Background

Elevated lipid profiles and impaired glucose homeostasis are risk factors for several cardiovascular diseases (CVDs), which, subsequently, represent a leading cause of early mortality, worldwide. The aim of the current study was to conduct a systematic review and meta-analysis of the effect of apple cider vinegar (ACV) on lipid profiles and glycemic parameters in adults.

Methods

A systematic search was conducted in electronic databases, including Medline, Scopus, Cochrane Library, and Web of Knowledge, from database inception to January 2020. All clinical trials which investigated the effect of ACV on lipid profiles and glycemic indicators were included. Studies were excluded if ACV was used in combination with other interventions or when the duration of intervention was < 2 weeks. To account for between-study heterogeneity, we performed meta-analysis using a random-effects model.

Results

Overall, nine studies, including 10 study arms, were included in this meta-analysis. We found that ACV consumption significantly decreased serum total cholesterol (− 6.06 mg/dL; 95% CI: − 10.95, − 1.17; I²: 39%), fasting plasma glucose (− 7.97 mg/dL; 95% CI: − 13.74, − 2.21; I²: 75%), and HbA1C concentrations (− 0.50; 95% CI: − 0.90, − 0.09; I²: 91%). No significant effect of ACV consumption was found on serum LDL-C, HDL-C, fasting insulin concentrations, or HOMA-IR. The stratified analysis revealed a significant reduction of serum TC and TG in a subgroup of patients with type 2 diabetes, those who took ≤15 mL/day of ACV, and those who consumed ACV for > 8-weeks, respectively. Furthermore, ACV consumption significantly decreased FPG levels in a subgroup of studies that administered ACV for > 8-weeks. Further, ACV intake appeared to elicit an increase in FPG and HDL-C concentrations in apparently healthy participants.

Conclusion

We found a significant favorable effect of ACV consumption on FPG and blood lipid levels.

Associations of time-varying obesity and metabolic syndrome with risk of incident heart failure and its subtypes: Findings from the Multi-Ethnic Study of Atherosclerosis

OBJECTIVE

Most previous studies have examined associations between metabolic disorders measured at a single point in time and risk of heart failure (HF). However, there are many situations where the values of exposures vary over time before HF occurs. We aimed to examine the associations of time-varying obesity and metabolic syndrome (MetSyn) measured at multiple points in time with HF.

METHODS

A total of 6750 participants in the Multi-Ethnic Study of Atherosclerosis from 2000 were included in the study. Follow-up was completed through December 2015. MetSyn was defined using the American Heart Association criteria. Incident HF was diagnosed by clinical criteria. Subtypes HF (reduced ejection fraction (HFrEF) and preserved (HFpEF) were classified by left ventricular EF.

RESULTS

A total of 331 HF cases were identified during 82,609 person-years of observation. The incidence (95%CI) of total HF was 4.0 (3.4-4.4) per 1000 person-years. Of the total HF cases, 45.6% were HFrEF (n = 151), 40.8% HFpEF (n = 135), and 13.6% were unclassified HF subtypes (n = 45). After adjusting for key covariates, time-varying obesity (BMI ≥ 30 kg/m²) and MetSyn were significantly associated with HF, with a stronger association for HFpEF than for HFrEF. The corresponding hazards ratios (HR, 95%CI) were 1.97 (1.43-2.72) and 1.86 (1.43-2.42) for HFpEF, and 1.46 (1.07-1.98), and 1.39 (1.06-1.82) for HFrEF respectively. Time-varying large waist circumference was significantly associated with for HFpEF, but not with HFrEF.

CONCLUSION

Time-varying obesity and MetSyn were significantly associated with HF risk, with a stronger association with HFpEF than with HFrEF. Continued effort to control these risk factors is recommended.

Prevalence and associated factors of uncontrolled hyperlipidemia among Thai patients with diabetes and clinical atherosclerotic cardiovascular diseases: a cross-sectional study

Objectives

The research aimed to determine the prevalence and associated factors of uncontrolled hyperlipidemia among Thai patients with the disease and Clinical ASCVD.

Results

A total of 1,527 Thai diabetic patients with a history of ASCVD were included in the study. Uncontrolled hyperlipidemia was detected among 1,216 patients (79.6%; 95% CI 77.6–81.7). The independent factors associated with uncontrolled hyperlipidemia included being female (adjusted odds ratio (AORs); 1.5, 95% CI 1.2–2.0), using thiazolidinedione (AORs; 1.7, 95% CI 1.1–2.7), community hospital (AORs; 4.3, 95% CI 1.0–18.0) and BMI level at 18.5–22.9 kg/m² (AORs; 2.2, 95% CI 1.2–4.0), 23.0–24.9 kg/m² (AORs; 1.8 95% CI 0.9–3.3), 25.0–29.9 kg/m² (AORs; 2.3 95% CI 1.3–4.3) and ≥ 30 kg/m² (AORs; 2.5 95% CI 1.3–4.9).

Non-coding Single Nucleotide Variants of Renin and the (Pro)renin Receptor are Associated with Polygenic Diseases in a Bangladeshi Population

Non-coding variants or single-nucleotide polymorphisms (SNPs) play pivotal roles in orchestrating pathogeneses of polygenic diseases, including hypertension (HTN) and diabetes. Renin-angiotensin system (RAS) components-renin and (pro)renin receptor [(P)RR]-maintain homeostasis of body fluids. Genetic variants of RAS components are associated with risk of HTN and type 2 diabetes (T2D) in different ethnic groups. We identified associations of SNPs within the renin and (P)RR genes with HTN, T2D, and T2D-associated hypertension in 911 unrelated Bangladeshi individuals. Five non-coding SNPs were involved in modulating regulatory elements in diverse cell types when tagged with other SNPs. rs61827960 was not associated with any disease; rs3730102 was associated with increased risk of HTN and T2D while under dominant model, it showed protective role against T2D-associated HTN. SNP rs11571079 was associated with increased risk of HTN and T2D-associated HTN and decreased risk of T2D, exerting a protective effect. Renin haplotypes GCA and GTG were related to increased risk of T2D and T2D-associated HTN, respectively. Heterogeneous linkage of genotypic and allelic frequencies of rs2968915 and rs3112298 of (P)RR was observed. The (P)RR haplotype GA was associated with increased risk of HTN and significantly decreased risk of T2D. These findings highlight important roles of non-coding variants of renin and (P)RR genes in the etiology of several polygenic diseases.

Cardiovascular Risk Factor Status in Hospitalized Patients With Type 2 Diabetes in China

BACKGROUND

Controlling blood glucose, blood pressure, and blood lipid is of great importance for patients with type 2 diabetes, not only for cardiovascular disease, but also for other complications. Previous studies mainly focused on the control rate of outpatients, and the results were suboptimal, but few studies aimed at the inpatients.

METHOD

The present study involved 3,245 hospitalized patients with type 2 diabetes from 2013 to 2017 in the Department of Endocrinology and Metabolism of Tianjin Medical University General Hospital. The percentages of inpatients who attained the goals of the China Diabetes Society and the American Diabetes Association were calculated for major cardiovascular risk factors (HbA1c, blood pressure, and blood lipid). The prevalence of microvascular and macrovascular complications was also assessed.

RESULT

The percentages of patients who met the Chinese Diabetes Society goals-HbA1c <7%, blood pressure <130/80 mmHg, normal lipids, and all three goals-were 26.7, 14.8, 10.4, and 0.2% in 2013 and 30.5, 16.2, 8.0, and 0.9% in 2017, respectively. The percentage of patients who met all three American Diabetes Association goals (HbA1c<7%, blood pressure <140/90 mmHg, low-density lipoprotein cholesterol <2.6 mmol/L) increased from 4.3% in 2013 to 9.0% in 2017. The prevalence of major diabetes complications including coronary heart disease (31.7 vs. 31.9%), stroke (16.7 vs. 14.8%), diabetic kidney disease (37.9 vs. 35.8%), diabetic retinopathy (48.0 vs. 46.5%), neuropathy (63.1 vs. 61.9%), and diabetic foot (0.8 vs. 1.2%) were stable from 2013 to 2017.

CONCLUSION

During 2013 to 2017, control rates of major cardiovascular risk factors including HbA1c, blood pressure, and low-density lipoprotein cholesterol were improved among hospitalized patients in Tianjin, China.

Blood pressure targets in adults with hypertension

BACKGROUND

This is the first update of this review first published in 2009. When treating elevated blood pressure, doctors usually try to achieve a blood pressure target. That target is the blood pressure value below which the optimal clinical benefit is supposedly obtained. "The lower the better" approach that guided the treatment of elevated blood pressure for many years was challenged during the last decade due to lack of evidence from randomised trials supporting that strategy. For that reason, the standard blood pressure target in clinical practice during the last years has been less than 140/90 mm Hg for the general population of patients with elevated blood pressure. However, new trials published in recent years have reintroduced the idea of trying to achieve lower blood pressure targets. Therefore, it is important to know whether the benefits outweigh harms when attempting to achieve targets lower than the standard target.

OBJECTIVES

The primary objective was to determine if lower blood pressure targets (any target less than or equal to 135/85 mm Hg) are associated with reduction in mortality and morbidity as compared with standard blood pressure targets (less than or equal to 140/ 90 mm Hg) for the treatment of patients with chronic arterial hypertension. The secondary objectives were: to determine if there is a change in mean achieved systolic blood pressure (SBP) and diastolic blood pressure (DBP associated with "lower targets" as compared with "standard targets" in patients with chronic arterial hypertension; and to determine if there is a change in withdrawals due to adverse events with "lower targets" as compared with "standard targets", in patients with elevated blood pressure.

SEARCH METHODS

The Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials up to May 2019: the Cochrane Hypertension Specialised Register, CENTRAL (2019, Issue 4), Ovid MEDLINE, Ovid Embase, the WHO International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also contacted authors of relevant papers regarding further published and unpublished work. The searches had no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing patients allocated to lower or to standard blood pressure targets (see above).

DATA COLLECTION AND ANALYSIS

Two review authors (JAA, VL) independently assessed the included trials and extracted data. Primary outcomes were total mortality; total serious adverse events; myocardial infarction, stroke, congestive heart failure, end stage renal disease, and other serious adverse events. Secondary outcomes were achieved mean SBP and DBP, withdrawals due to adverse effects, and mean number of antihypertensive drugs used. We assessed the risk of bias of each trial using the Cochrane risk of bias tool and the certainty of the evidence using the GRADE approach.  MAIN RESULTS: This update includes 11 RCTs involving 38,688 participants with a mean follow-up of 3.7 years. This represents 7 new RCTs compared with the original version. At baseline the mean weighted age was 63.1 years and the mean weighted blood pressure was 155/91 mm Hg. Lower targets do not reduce total mortality (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.86 to 1.05; 11 trials, 38,688 participants; high-certainty evidence) and do not reduce total serious adverse events (RR 1.04, 95% CI 0.99 to 1.08; 6 trials, 18,165 participants; moderate-certainty evidence). This means that the benefits of lower targets do not outweigh the harms as compared to standard blood pressure targets. Lower targets may reduce myocardial infarction (RR 0.84, 95% CI 0.73 to 0.96; 6 trials, 18,938 participants, absolute risk reduction (ARR) 0.4%, number needed to treat to benefit (NNTB) 250 over 3.7 years) and congestive heart failure (RR 0.75, 95% CI 0.60 to 0.92; 5 trials, 15,859 participants, ARR 0.6%, NNTB  167 over 3.7 years) (low-certainty for both outcomes). Reduction in myocardial infarction and congestive heart failure was not reflected in total serious adverse events. This may be due to an increase in other serious adverse events (RR 1.44, 95% CI 1.32 to 1.59; 6 trials. 18,938 participants, absolute risk increase (ARI) 3%,  number needed to treat to harm (NNTH) 33 over four years) (low-certainty evidence). Participants assigned to a "lower" target received one additional antihypertensive medication and achieved a significantly lower mean SBP (122.8 mm Hg versus 135.0 mm Hg, and a lower mean DBP (82.0 mm Hg versus 85.2 mm Hg, than those assigned to "standard target".

AUTHORS' CONCLUSIONS

For the general population of persons with elevated blood pressure, the benefits of trying to achieve a lower blood pressure target rather than a standard target (≤ 140/90 mm Hg) do not outweigh the harms associated with that intervention. Further research is needed to see if some groups of patients would benefit or be harmed by lower targets. The results of this review are primarily applicable to older people with moderate to high cardiovascular risk. They may not be applicable to other populations.

Anti-Obesity and Antidiabetic Effects of Nelumbinis Semen Powder in High-Fat Diet-Induced Obese C57BL/6 Mice

Nelumbinis Semen (NS, the seeds of Nelumbo nucifera) extract is a traditional Korean medicine with anti-oxidant activity. The present study examined the anti-obesity and antidiabetic effects of NS powder in high-fat diet (HFD)-induced obese C57BL/6 mice. Mice (n = 8/group) were fed a normal diet (CON), HFD, HFD containing 5% NS powder (HFD-NS5%), or HFD containing 10% NS powder (HFD-NS10%) for 12 weeks. Food intake was relatively higher in groups HFD-NS5% and HFD-NS10%, while the food efficiency ratio was highest in group HFD (p < 0.05). HFD-NS5% reduced the body weight (-39.1%) and fat weight (-26.6%), including epididymal fat and perirenal fat, and lowered the serum triglyceride levels (-20.6%) compared with HFD. Groups HFD-NS5% and HFD-NS10% showed hepatoprotective properties, reducing the serum ALT levels (p < 0.05) and fat globules (size and number) in the liver compared with group HFD. HFD-NS5% and HFD-NS10% regulated the blood glucose, improved the glucose intolerance, and showed a 12.5% and 15.0% reduction in the area under the curve (AUC) of intraperitoneal glucose tolerance test (IPGTT), and a 26.8% and 47.3% improvement in homeostatic model assessment insulin resistance (HOMA-IR), respectively, compared with HFD (p < 0.05). Regarding the expressions of genes related to anti-obesity and antidiabetes, there was a 1.7- and 1.3-fold increase in PPAR-α protein expression, 1.4- and 1.6-fold increase in PPAR-γ protein expression, and 0.7- and 0.6-fold decrease in TNF-α protein expression, respectively, following HFD-NS5% and HFD-NS10% treatments, compared with HFD, and GLUT4 protein expression increased relative to CON (p < 0.05). These results comprehensively provide the fundamental data for NS powder's functional and health-promoting benefits associated with anti-obesity and antidiabetes.

A Comprehensive Update on Aspirin Management During Noncardiac Surgery

Aspirin is considered critical lifelong therapy for patients with established cardiovascular (CV) disease (including coronary artery, cerebrovascular, and peripheral arterial diseases) and is consequently one of the most widely used medications worldwide. However, the indications for aspirin use continue to evolve and recent trials question its efficacy for primary prevention. Although one third of patients undergoing noncardiac surgery and at risk for a major adverse CV event receive aspirin perioperatively, uncertainty still exists about how aspirin should be optimally managed in this context, and significant practice variability remains. Recent trials suggest that the risks of continuing aspirin during the perioperative period outweigh the benefits in many cases, but data on patients with high CV risk remain limited. We performed a comprehensive PubMed and Medline literature search using the following keywords: aspirin, aspirin withdrawal, perioperative, coronary artery disease, cerebrovascular disease, peripheral artery disease, and CV disease; we manually reviewed all relevant citations for inclusion. Patients taking aspirin for the primary prevention of CV disease should likely discontinue it during the perioperative period, especially when there is a high risk of bleeding. Patients with established CV disease but without a coronary stent should likely continue aspirin during the perioperative period unless undergoing closed-space surgery. Patients with a history of coronary stenting also likely need aspirin continuation throughout the perioperative period for nonclosed space procedures. Perioperative clinicians need to balance the risks of ceasing aspirin before surgery against its continuation during the perioperative interval using a patient-specific strategy. The guidance on decision-making with regard to perioperative aspirin cessation or continuation using currently available clinical data from studies in high-risk patients along with nonclinical aspirin studies is conflicting and does not enable a simplified or unified answer. However, pertinent guidelines on CV disease management provide a basic framework for aspirin management, and large trial findings provide some insight into the safety of perioperative aspirin cessation in some contexts, although uncertainty on perioperative aspirin still exists. This review provides an evidence-based update on perioperative aspirin management in patients undergoing noncardiac surgery with a focus on recommendations for perioperative clinicians on continuing versus holding aspirin during this context.

Comparing the Preferences of Patients and the General Public for Treatment Outcomes in Type 2 Diabetes Mellitus

BACKGROUND

Healthcare treatments and interventions are traditionally evaluated from the societal perspective, but a more patient-centric perspective has been proposed in recent years. We sought to compare preferences of patients and the general public for treatment outcomes of type 2 diabetes using both best-worst scaling (BWS) and rating approaches.

METHODS

A survey evaluating the treatment priorities for type 2 diabetes was conducted in the United States. Members of the general public and patients with type 2 diabetes were recruited from a nationally sampled panel. Participants indicated the importance of seven potential treatment outcomes (hypoglycemic events, glycated hemoglobin [A1c], weight loss, mental health, functioning, glycemic stability, and cardiovascular health) using (1) BWS case 1 and (2) a rating task. Preference differences from BWS prioritizations were explored using mixed logistic regression (BWS preference weights were probability re-scaled so that the weightings of the seven items collectively summed to 100). The consistency of scale between samples was explored using heteroskedastic conditional logistic regression of BWS data. Spearman rank correlation was used to compare standardized BWS preference weights and rating scores for each group. Both groups evaluated the BWS and rating activities using debriefing questions.

RESULTS

The public and patient samples included 314 and 313 respondents, respectively. The public was on average 16 years younger than patients (48 vs 64 years, P < 0.001). In BWS, patients and the public both ranked A1c, glycemic stability, and cardiovascular health within their top three outcomes. Patients valued the outcome A1c most highly and found it twice as important as did the public (41.0 vs 20.2, P < 0.001). The public valued cardiovascular health most highly, and found it to be twice as important than did patients (31.3 vs 17.4, P < 0.001). Patients were more consistent in their preferences than the public (λ = 1.66, P = 0.01). Preferences elicited using BWS and rating approaches were highly correlated for both patients (ρ = 0.96) and the public (ρ = 0.92). Patients were more likely than the public to endorse the BWS as easy to answer (P < 0.001), easy to understand (P < 0.001), consistent with preferences (P < 0.001), and relevant (P < 0.001). Both patients and the public found the rating activity easier to answer and understand, and more consistent with their preferences, than the BWS (P < 0.001).

CONCLUSIONS

We provide some of the first evidence demonstrating a difference in patient and public treatment priorities for diabetes. That patients were more consistent in their preferences than the public and found the BWS and Likert rating instruments more relevant suggests that patient priorities may be more appropriate than those of the general public in some medical decision-making contexts.

Albuminuria as a Predictor of Cardiovascular Outcomes in Patients With Acute Myocardial Infarction

Background In patients with myocardial infarction ( MI ), reduced kidney function is recognized as an important predictor of poor prognosis, but the impact of albuminuria, a representative measure of kidney damage, has not been extensively evaluated. Methods and Results In the SCREAM (Stockholm Creatinine Measurements) project (2006-2012), we identified 2469 patients with incident MI with dipstick proteinuria measured within a year before MI (427 patients also had urine albumin to creatinine ratio [ ACR ] measured concurrently) and obtained estimates for ACR with multiple imputation in participants with data solely on dipstick proteinuria. We quantified the association of ACR with the post- MI composite and individual outcomes of all-cause mortality, cardiovascular mortality, recurrent MI , ischemic stroke, or heart failure using Cox models and then evaluated the improvement in C statistic. During a median follow-up of 1.0 year after MI , 1607 participants (65.1%) developed the post- MI composite outcome. Higher ACR levels were independently associated with all outcomes except for ischemic stroke. Per 8-fold higher ACR (eg, 40 versus 5 mg/g), the hazard ratio of composite outcome was 1.21 (95% CI , 1.08-1.35). The addition of the ACR improved the C statistic of the post- MI composite by 0.040 (95% CI, 0.030-0.051). Largely similar results were obtained regardless of diabetic status and when ACR or dipstick was separately analyzed without imputation. Conclusions In patients with MI , albuminuria was a potent predictor of subsequent outcomes, suggesting the importance of paying attention to the information on albuminuria, in addition to kidney function, in this high-risk population.

Association Between Road Traffic Noise and Incidence of Diabetes Mellitus and Hypertension in Toronto, Canada: A Population-Based Cohort Study

Background Exposure to road traffic noise has been linked to cardiometabolic complications, such as elevated blood pressure and glucose dysregulation. However, epidemiologic evidence linking road traffic noise to diabetes mellitus and hypertension remains scarce. We examined associations between road traffic noise and the incidence of diabetes mellitus and hypertension in Toronto, Canada. Methods and Results Using the Ontario Population Health and Environment Cohort, we conducted a retrospective, population-based cohort study of long-term residents of Toronto, aged 35 to 100 years, who were registered for provincial publicly funded health insurance, and were without a history of hypertension (n=701 174) or diabetes mellitus (n=914 607). Road traffic noise exposure levels were assessed by the equivalent continuous A-weighted sound pressure level (dBA) for the 24-hour day and the equivalent continuous A-weighted sound pressure level for the night (11 pm-7am). Noise exposures were assigned to subjects according to their annual residential postal codes during the 15-year follow-up. We used random-effect Cox proportional hazards models adjusting for personal and area-level characteristics. From 2001 to 2015, each interquartile range increase in the equivalent continuous A-weighted sound pressure level (dBA) for the 24-hour day (10.0 dBA) was associated with an 8% increase in incident diabetes mellitus (95% CI, 1.07-1.09) and a 2% increase in hypertension (95% CI, 1.01-1.03). We obtained similar estimates with the equivalent continuous A-weighted sound pressure level for the night (11 pm-7am). These results were robust to all sensitivity analyses conducted, including further adjusting for traffic-related air pollutants (ultrafine particles and nitrogen dioxide). For both hypertension and diabetes mellitus, we observed stronger associations with the equivalent continuous A-weighted sound pressure level (dBA) for the 24-hour day among women and younger adults (aged <60 years). Conclusions Long-term exposure to road traffic noise was associated with an increased incidence of diabetes mellitus and hypertension in Toronto.

Impact of atherosclerotic cardiovascular disease on healthcare resource utilization and costs in patients with type 2 diabetes mellitus in a real-world setting

Background

This study evaluated the impact of atherosclerotic cardiovascular disease (ASCVD) on healthcare resource utilization and costs in patients with type 2 diabetes mellitus (T2DM).

Methods

This study was a retrospective, cross-sectional study using US claims data. Adult patients with T2DM were stratified by presence or absence of ASCVD and compared regarding annual (2015) healthcare resource utilization and associated costs. Subgroup analyses were conducted for three age groups (18–44, 45–64, and ≥ 65 years).

Results

Among 1,202,596 eligible patients with T2DM, 45.2% had documented ASCVD. The proportions of patients with inpatient and ER-based resource utilization during 2015 were three-to-four times greater in the ASCVD cohort as compared to the non-ASCVD cohort for the categories of inpatient visits (15.6% vs 4.4% of patients), outpatient ER visits (18.4% vs 5.2% of patients), and inpatient ER visits (4.3% vs 0.9% of patients). Outpatient utilization also was higher among patients with ASCVD as compared to those without ASCVD (mean number of annual office visits per patient, 9.1 vs 5.6), and more than twice as many patients with ASCVD had ≥ 9 office visits (43.5% vs 19.8%). Average per-patient total healthcare cost was $22,977 for ASCVD vs $9735 for non-ASCVD, with medical costs primarily driving the difference ($17,849 vs $6079); the difference in pharmacy costs was smaller ($5128 vs $3656). In the 18–44, 45–64, and ≥ 65 age subgroups respectively, total annual healthcare costs were 143, 127, and 114% higher in ASCVD vs non-ASCVD patients.

Conclusions

These findings indicate significantly higher healthcare resource utilization and associated costs in patients having T2DM with ASCVD compared to T2DM without ASCVD.

Association of depression and diabetes complications and mortality: a population-based cohort study

AIMS

Several studies suggested that depression might worsen the clinical outcome of diabetes mellitus; however, such association was confounded by duration of illness and baseline complications. This study aimed to assess whether depression increases the risk of diabetes complications and mortality among incident patients with diabetes.

METHODS

This was a population-based matched cohort study using Taiwan's National Health Insurance Research Database. A total of 38 537 incident patients with diabetes who had depressive disorders and 154 148 incident diabetes patients without depression who were matched by age, sex and cohort entry year were randomly selected. The study endpoint was the development of macrovascular and microvascular complications, all-cause mortality and cause-specific mortality.

RESULTS

Among participants, the mean (±SD) age was 52.61 (±12.45) years, and 39.63% were male. The average duration of follow-up for mortality was 5.5 years, ranging from 0 to 14 years. The adjusted hazard ratios were 1.35 (95% confidence interval [CI], 1.32-1.37) for macrovascular complications and 1.08 (95% CI, 1.04-1.12) for all-cause mortality. However, there was no association of depression with microvascular complications, mortality due to cardiovascular diseases or mortality due to diabetes mellitus. The effect of depression on diabetes complications and mortality was more prominent among young adults than among middle-aged and older adults.

CONCLUSIONS

Depression was associated with macrovascular complications and all-cause mortality in our patient cohort. However, the magnitude of association was less than that in previous studies. Further research should focus on the benefits and risks of treatment for depression on diabetes outcome.

Stress Testing Versus CT Angiography in Patients With Diabetes and Suspected Coronary Artery Disease

BACKGROUND

The optimal noninvasive test (NIT) for patients with diabetes and stable symptoms of coronary artery disease (CAD) is unknown.

OBJECTIVES

The purpose of this study was to assess whether a diagnostic strategy based on coronary computed tomographic angiography (CTA) is superior to functional stress testing in reducing adverse cardiovascular (CV) outcomes (CV death or myocardial infarction [MI]) among symptomatic patients with diabetes.

METHODS

PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) was a randomized trial evaluating an initial strategy of CTA versus functional testing in stable outpatients with symptoms suggestive of CAD. The study compared CV outcomes in patients with diabetes (n = 1,908 [21%]) and without diabetes (n = 7,058 [79%]) based on their randomization to CTA or functional testing.

RESULTS

Patients with diabetes (vs. without) were similar in age (median 61 years vs. 60 years) and sex (female 54% vs. 52%) but had a greater burden of CV comorbidities. Patients with diabetes who underwent CTA had a lower risk of CV death/MI compared with functional stress testing (CTA: 1.1% [10 of 936] vs. stress testing: 2.6% [25 of 972]; adjusted hazard ratio: 0.38; 95% confidence interval: 0.18 to 0.79; p = 0.01). There was no significant difference in nondiabetic patients (CTA: 1.4% [50 of 3,564] vs. stress testing: 1.3% [45 of 3,494]; adjusted hazard ratio: 1.03; 95% confidence interval: 0.69 to 1.54; p = 0.887; interaction term for diabetes p value = 0.02).

CONCLUSIONS

In diabetic patients presenting with stable chest pain, a CTA strategy resulted in fewer adverse CV outcomes than a functional testing strategy. CTA may be considered as the initial diagnostic strategy in this subgroup. (PROspective Multicenter Imaging Study for Evaluation of Chest Pain [PROMISE]; NCT01174550).

Risk factor analysis on the healing time and infection rate of diabetic foot ulcers in a referral wound care clinic

OBJECTIVE:

Objectives. To determine the prevalence and risk factors for diabetic foot infection (DFI), and to identify factors associated with delayed wound healing of diabetic foot ulcer (DFU).

METHOD:

The retrospective study was performed in a referral wound care clinic in Hospital Kuala Lumpur. Data was collected from January 2014 to October 2016 on DFU patients who attended this clinic.

RESULTS:

Of the 340 patients (216 male and 124 female) DFU patients who attended the clinic (mean age: 58.1±10.8 years old), 41.5% presented with infection with a mean cross-sectional ulcer area of 21.5±33.2cm². Binary logistic regression analysis revealed that patients of Chinese ethnicity (OR: 3.39; 95%CI 1.49 to 7.70), with fasting blood glucose ≥7mmol/l (OR: 3.41; 95%CI 1.57 to 7.39), ulcer size ≥10cm² (OR: 2.90; 95%CI 1.45 to 5.82) and blood pressure ≥140/90mmHg (OR: 2.52; 95%CI 1.54 to 4.14) were more likely to develop DFI. The median healing time for patients with DFUs was three months. There were six variables identified as significantly associated with prolonged healing time of DFU, namely presence of infection (p<0.001), poor glycaemic control with fasting blood glucose ≥7mmol/l (p<0.001), high blood pressure ≥140/90mmHg (p<0.001), large DFU size ≥2cm² (p<0.001), history of amputation (p<0.005) and plantar location of the DFU (p<0.05).

CONCLUSION:

Large DFU size, poor glycaemic and blood pressure control are common risk factors for both DFU and DFI. Unexpected high prevalence and ethnicity risk factor for DFI urge more comprehensive primary and secondary preventative strategies to reduce its incidence.

Daily Aspirin Use Associated With Reduced Risk For Fibrosis Progression In Patients With Nonalcoholic Fatty Liver Disease

BACKGROUND & AIMS

There are few data from prospective studies on the effects of aspirin on fibrosis in patients with nonalcoholic fatty liver disease (NAFLD).

METHODS

We performed a prospective cohort study of 361 adults with biopsy-confirmed NAFLD, from 2006 through 2015, examined every 3-12 months for incident advanced fibrosis defined using serial measurements of validated indices (the Fibrosis-4, NAFLD fibrosis score, and aspartate aminotransferase to platelet ratio indices). Histologic analyses of liver biopsies collected at baseline were performed by a blinded pathologist. Information collected at baseline and at each examination included frequency and duration of aspirin and nonsteroidal anti-inflammatory drug (NSAID) use. Using multivariable-adjusted logistic regression, we estimated the association of aspirin use with prevalent steatohepatitis (NASH) and fibrosis. Using multivariable-adjusted Cox proportional hazards modeling, we estimated the association between aspirin use and risk for fibrosis progression.

RESULTS

At enrollment, 151 subjects used aspirin daily. Compared with non-regular use, daily aspirin use was associated with significantly lower odds of NASH (adjusted odds ratio, 0.68; 95% CI, 0.37-0.89) and fibrosis (adjusted odds ratio, 0.54; 95% CI, 0.31-0.82). Among individuals with baseline F0-F2 fibrosis (n = 317), 86 developed advanced fibrosis over 3692 person-years. Daily aspirin users had significantly lower risk for developing incident advanced fibrosis vs non-regular users (adjusted hazard ratio [aHR], 0.63; 95% CI, 0.43-0.85). This relationship appeared to be duration dependent (adjusted P trend=.026), with the greatest benefit found with at least 4 years or more of aspirin use (aHR, 0.50; 95% CI, 0.35-0.73). Conversely, use of nonaspirin NSAIDs was not associated with risk for advanced fibrosis (aHR, 0.93; 95% CI, 0.81-1.05).

CONCLUSIONS

In a prospective study of patients with biopsy-proven NAFLD, daily aspirin use was associated with less severe histologic features of NAFLD and NASH, and lower risk for progression to advanced fibrosis with time.

Lowering Targeted Atherogenic Lipoprotein Cholesterol Goals for Patients at "Extreme" ASCVD Risk

PURPOSE OF REVIEW

To review randomized interventional clinical and imaging trials that support lower targeted atherogenic lipoprotein cholesterol goals in "extreme" and "very high" atherosclerotic cardiovascular disease (ASCVD) risk settings. Major atherosclerotic cardiovascular event (MACE) prevention among the highest risk patients with ASCVD requires aggressive management of global risks, including lowering of the fundamental atherogenic apolipoprotein B-associated lipoprotein cholesterol particles [i.e., triglyceride-rich lipoprotein remnant cholesterol, low-density lipoprotein cholesterol (LDL-C), and lipoprotein(a)]. LDL-C has been the long-time focus of imaging studies and randomized clinical trials (RCTs). The 2004 adult treatment panel (ATP-III) update recognized that the long-standing targeted LDL-C goal of < 100 mg/dL potentially fostered substantial undertreatment of the very highest coronary heart disease (CHD) risk individuals and was lowered to < 70 mg/dL as an "optional" goal for "very high" 10-year CHD [CHD death + myocardial infarction (MI)] risk exceeding 20%. This evidence-based guideline change was supported by the observed benefits demonstrated in the high-risk primary and secondary prevention populations in the Heart Protection Study (HPS), the acute coronary syndrome (ACS) population in the Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis in Myocardial Infarction 22 trial (PROVE-IT), and the secondary prevention population in the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) intravascular ultrasound (IVUS) study. Subsequent national and international guidelines maintained a targeted LDL-C goal < 70 mg/dL, or a threshold for management of > 70 mg/dL for patients with CHD, CHD risk equivalency, or ASCVD.

RECENT FINDINGS

Subgroup or meta-analyses of several RCTs, IVUS imaging studies, and the ACS population in IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT) supported the evidence-based 2017 American Association Clinical Endocrinologist (AACE) guideline change establishing a targeted LDL-C goal < 55 mg/dL, non-HDL-C < 80 mg/dl, and apolipoprotein B (apo B) < 70 mg/dL for patients at "Extreme" ASCVD risk, i.e., 10-year 3-point-MACE-composite (CV death, non-fatal MI, or ischemic stroke) risk exceeding 30%. Moreover, with no recognized lower-limit-associated intolerance or safety issues, even more intensive lowering of atherogenic cholesterol levels is supported by the following evidence base: (1) analysis of eight high-intensity statin-based prospective secondary prevention IVUS atheroma volume regression trials; (2) a distribution analysis of on-treatment, ezetimibe and background-statin, of the very low LDL-C levels reached and CVD event risk in the IMPROVE-IT ACS population; (3) the secondary prevention Global Assessment of Pl\aque Regression With a PCSK9 Antibody as Measured by Intravascular Ultrasound (GLAGOV) on background-statin; and (4) the secondary prevention population of Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk (FOURIER). By example, in FOURIER, the population on background-statin at a baseline median 92 mg/dL achieved median LDL-C level of 30 mg/dL and non-HDL-C to < 65 mg/dl, and apo B to < 50 mg/dL, and subgroup and post hoc analyses all demonstrated additional ASCVD event reduction benefits as LDL-C was further reduced. The level of ASCVD risk determines the degree, urgency, and persistence in global risk management, including fundamental atherogenic lipoprotein cholesterol particle lowering. "Extreme" risk patients may require extremely low targeted LDL-C, non-HDL-C and apo B goals; such efforts, implied by more recent interventional trials and analyses, are aimed at maximal atheroma plaque regression, stabilization, and MACE event reduction with the aspiration of improved quality lifespan.

Proteinuria is independently associated with the incidence of primary cardiovascular events in diabetic patients

BACKGROUND

Albuminuria is a risk factor for cardiovascular events in diabetic patients, but it is unknown whether proteinuria is also a risk factor for cardiovascular events in these patients.

METHODS

The Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD) trial was performed between 2002 and 2008 to examine the efficacy of low-dose aspirin therapy for the primary prevention of cardiovascular events in type 2 diabetes patients. After the JPAD trial was completed, we continued to follow up the patients until 2015. Among the 2536 patients participating in the JPAD study, 42 were excluded because proteinuria was not checked at registration. We divided the patients into two groups: proteinuria group (n = 446; proteinuria ± or greater) and non-proteinuria groups (n = 2048; proteinuria -). We compared the incident rate of cardiovascular events between the two groups.

RESULTS

During the observation period [median, 10.3 (10.2-10.5) years], 332 patients had a first cardiovascular event. Among 332 patients, 136 patients had cerebrovascular events and 54 patients had acute myocardial infarction. The incidence rate of cardiovascular events was significantly higher in the proteinuria group compared with the non-proteinuria group (HR 1.75, 95%CI 1.36-2.23, p < 0.0001). The incidence rate of cerebrovascular events was also significantly higher in the proteinuria group than in the non-proteinuria group (HR 1.71, 95%CI 1.14-2.49, p = 0.0064). The Cox proportional hazards model revealed that proteinuria was independently associated with cardiovascular events in diabetic patients without a history of cardiovascular events after adjusting for age, gender, body mass index, hemoglobin A1c level, duration of diabetes, and estimated glomerular filtration rate.

CONCLUSIONS

Proteinuria was independently associated with the incidence of primary cardiovascular events in diabetic patients. Proteinuria detected by the dipstick test, which is simple and inexpensive, is useful as a first step in the risk assessment of diabetic patients.

Aspirin for Primary Prevention of Cardiovascular Disease

Aspirin has been used for decades for the primary and secondary prevention of cardiovascular disease (CVD). The effect of aspirin in secondary prevention is well-known but is still debatable for primary prevention. Despite the controversy, aspirin is believed to have a beneficial effect in primary prevention and has been widely used. However, whether the doubts concerning the wide use of aspirin are correct has resulted in the publication of data from several large clinical trials recently. There are several clinical guidelines from various international organizations on the use of aspirin for the primary prevention of CVD, and they offer some conflicting recommendations. A reduction in the overall incidence of CVD with the development of modern prevention therapies has weakened the impact of aspirin in primary prevention. Large randomized clinical trials have found decreased or no difference in CVD events but a significant increase in the risk of bleeding. Taking aspirin for the primary prevention of CVD is no longer recommended, especially for patients who have a low to moderate risk. An assessment of the balance between the benefits and risks of aspirin use should be considered.

Extreme Atherosclerotic Cardiovascular Disease (ASCVD) Risk Recognition

PURPOSE OF REVIEW

To distinguish extreme and very high atherosclerotic cardiovascular disease (ASCVD) event risk based on prospective epidemiological studies and clinical trial results.

RECENT FINDINGS

Clinical practice guidelines have categorized patients with either a history of one or more "clinical ASCVD" events or "coronary heart disease (CHD) risk equivalency" to be at "very high risk" for a recurrence or a first event, respectively. A 20% or greater 10-year ASCVD risk for a composite 3-point "major" atherosclerotic cardiovascular event (MACE) of non-fatal myocardial infarction (MI), non-fatal stroke, or cardiovascular death can serve as an arbitrary definition of those at "very high risk." Exclusion of stroke may underestimate risk of "hard" endpoint 10-year ASCVD risk and addition of other potential endpoints, e.g., hospital admission for unstable angina or revascularization, a 5-point composite MACE, may overinflate the risk definitions and categorization. "Extreme" risk, a descriptor for even higher morbidity and mortality potential, defines a 30% or greater 10-year 3-point MACE (ASCVD) risk. In prospective, epidemiological studies and randomized clinical trial (RCT) participants with an initial acute coronary syndrome (ACS) within several months of entry into the study meet the inclusion criteria assignment for extreme risk. In survivors beyond the first year of an ASCVD event, "extreme" risk persists when one or more comorbidities are present, including diabetes, heart failure (HF), stage 3 or higher chronic kidney disease (CKD), familial hypercholesterolemia (FH), and poorly controlled major risk factors such as hypertension and persistent tobaccoism. "Extreme" risk particularly applies to those with progressive or multiple clinical ASCVD events in the same artery, same arterial bed, or polyvascular sites, including unstable angina and transient ischemic events. Identifying asymptomatic individuals with extensive subclinical ASCVD at "extreme" risk is a challenge, as risk engine assessment may not be adequate; individuals with genetic FH or those with diabetes and Agatston coronary artery calcification (CAC) scores greater than 1000 exemplify such threatening settings and opportunities for aggressive primary prevention. Heterogeneity exists among individuals at risk for clinical ASCVD events; identifying those at "extreme" risk, a more ominous ASCVD category, associated with greater morbidity and mortality, should prompt the most effective global cardiometabolic risk reduction.
