Cardiovascular Disease and Risk Management: Standards of Medical Care in Diabetes-2020

Factors Associated With the Cardiovascular Health of Black and Latino Adults With Type 2 Diabetes

AIMS

The purpose of this study was to assess the levels of cardiovascular health (CVH) of Black and Latino adults with type 2 diabetes (T2D) and examine the association of individual and microsystem level factors with their CVH score.

METHODS

This was a cross-sectional design in 60 Black and Latino Adults aged 18-40 with T2D. Data were collected on sociodemographic, individual (sociodemographic, diabetes self-management, sleep disturbance, depressive symptoms, quality of life, and the inflammatory biomarkers IL-6 and hs-CRP) and microsystem factors (family functioning), and American Heart Association's Life's Simple 7 metrics of CVH. Factors significantly associated with the CVH score in the bivariate analyses were entered into a linear regression model.

RESULTS

The sample had a mean age 34 ± 5 years and was primarily female (75%) with a mean CVH score was 8.6 ± 2.2 (possible range of 0-14). The sample achieved these CVH factors at ideal levels: body mass index <25 kg/m2 (8%); blood pressure <120/80 (42%); hemoglobin A1c < 7% (57%); total cholesterol <200 mg/dL (83%); healthy diet (18%); never or former smoker > one year (95%); and physical activity (150 moderate-to-vigorous minutes/week; 45%). In the multivariable model, two factors were significantly associated with cardiovascular health: hs-CRP (B = -0.11621, p < .0001) and the general health scale (B = 0.45127, p = .0013).

CONCLUSIONS

This sample had an intermediate level of CVH, with inflammation and general health associated with overall CVH score.

Role of Systemic Factors in Improving the Prognosis of Diabetic Retinal Disease and Predicting Response to Diabetic Retinopathy Treatment

Topic

To review clinical evidence on systemic factors that might be relevant to update diabetic retinal disease (DRD) staging systems, including prediction of DRD onset, progression, and response to treatment.

Clinical relevance

Systemic factors may improve new staging systems for DRD to better assess risk of disease worsening and predict response to therapy.

Methods

The Systemic Health Working Group of the Mary Tyler Moore Vision Initiative reviewed systemic factors individually and in multivariate models for prediction of DRD onset or progression (i.e., prognosis) or response to treatments (prediction).

Results

There was consistent evidence for associations of longer diabetes duration, higher glycosylated hemoglobin (HbA1c), and male sex with DRD onset and progression. There is strong trial evidence for the effect of reducing HbA1c and reducing DRD progression. There is strong evidence that higher blood pressure (BP) is a risk factor for DRD incidence and for progression. Pregnancy has been consistently reported to be associated with worsening of DRD but recent studies reflecting modern care standards are lacking. In studies examining multivariate prognostic models of DRD onset, HbA1c and diabetes duration were consistently retained as significant predictors of DRD onset. There was evidence of associations of BP and sex with DRD onset. In multivariate prognostic models examining DRD progression, retinal measures were consistently found to be a significant predictor of DRD with little evidence of any useful marginal increment in prognostic information with the inclusion of systemic risk factor data apart from retinal image data in multivariate models. For predicting the impact of treatment, although there are small studies that quantify prognostic information based on imaging data alone or systemic factors alone, there are currently no large studies that quantify marginal prognostic information within a multivariate model, including both imaging and systemic factors.

Conclusion

With standard imaging techniques and ways of processing images rapidly evolving, an international network of centers is needed to routinely capture systemic health factors simultaneously to retinal images so that gains in prediction increment may be precisely quantified to determine the usefulness of various health factors in the prognosis of DRD and prediction of response to treatment.

Omega-3 fatty acids for cardiovascular event lowering

Low-density lipoprotein cholesterol (LDL-C) is the main target for therapeutics aimed at reducing the risk of atherosclerotic cardiovascular disease (ASCVD) and downstream cardiovascular (CV) events. However, multiple studies have demonstrated that high-risk patient populations harbour residual risk despite effective LDL-C lowering. While data support the causal relationship between triglycerides and ASCVD risk, triglyceride-lowering therapies such as omega-3 fatty acids have shown mixed results in CV outcomes trials. Notably, icosapent ethyl, a purified formulation of eicosapentaenoic acid (EPA), has garnered compelling evidence in lowering residual CV risk in patients with hypertriglyceridaemia and treated with statins. In this review, we summarize studies that have investigated omega-3-fatty acids for CV event lowering and discuss the clinical implementation of these agents based on trial data and guidelines.

Clinical studies on pharmacological treatment of hypertension in Japan

Differences in the epidemiology and phenotypes of hypertension in Japan compared with Western countries mean that optimal approaches to the pharmacological management of hypertension should be based on local data. Fortunately, there is a large body of evidence from studies conducted in Japanese populations to inform guidelines and treatment decisions. This article highlights treatment recommendations and BP targets for Japanese patients with hypertension, and summarizes key literature supporting these recommendations. The latest version of the Japanese Society of Hypertension (JSH) guidelines is consistent with US and European guidelines in recommending that the general BP target should be <130/80 mmHg for office blood pressure (BP) and <125/75 mmHg for home BP. There is good local evidence to support these targets. The JSH guidelines also strongly recommend that antihypertensive therapy is managed and monitored based on home BP, due to the closer association of this parameter with cardiovascular risk compared with office BP. Japan is a leader in out-of-office BP research, meaning that there is good evidence for the Japanese recommendations. Key features of antihypertensive agents for use in Japanese patients with hypertension include the ability to reduce stroke risk provide antihypertensive efficacy throughout the 24-h dosing period. Calcium channel blockers appear to be particularly effective in Asian populations, and are the most commonly prescribed agents in Japan. Again consistent with international recommendations, antihypertensive therapy should be started with a combination of agents to maximize the chances of achieving target BP.

CVD incidence and mortality among people with diabetes and/or hypertension: Results from the English longitudinal study of ageing

BACKGROUND AND AIMS

Diabetes and/or hypertension are the most common conditions in older people, and also related to higher cardiovascular disease (CVD) incidence and mortality. This study aims to explore the risk of CVD incidence and mortality among older people with diabetes and/or hypertension over a 16 years follow-up period and investigates the role of depression and obesity in these relationships.

METHODS

6,855 participants aged 50+ from the English Longitudinal Study of Ageing (ELSA). The main exposure is having diabetes and/or hypertension at baseline (2002/2003) compared to not having, but excluded those with coronary heart disease (CHD) and/or stroke (CVD). Survival models are used for CVD incidence and mortality up to 2018, adjusted for socio-demographic, health, health behaviours, cognitive function, and physical function characteristics.

RESULTS

39.3% of people at baseline had diabetes and/or hypertension. The risk of CVD incidence was 1.7 (95%CI: 1.5; 1.9) higher among people with diabetes and/or hypertension compared to those without and was independent of covariates adjustment. People with diabetes and/or hypertension were also 1.3 (95%CI: 1.1; 1.8) times more likely to die from CVD than those without. We did not find evidence for an elevated risk of CVD incidence and mortality among people with obesity nor among those with depression.

CONCLUSIONS

In order to effectively reduce the risk of CVD incidence and mortality among older people, treatment as well as management of hypertension and diabetes should be routinely considered for older people with diabetes and/or hypertension.

Factors influencing optimal diabetes care and clinical outcomes in Thai patients with type 2 diabetes mellitus: a multilevel modelling analysis

BACKGROUND

Increasing levels of poor glycaemic control among Thai patients with type 2 diabetes mellitus (T2DM) motivated us to compare T2DM care between urban and suburban primary care units (PCUs), to identify gaps in care, and to identify significant factors that may influence strategies to enhance the quality of care and clinical outcomes in this population.

METHODS

We conducted a cross-sectional study involving 2160 patients with T2DM treated at four Thai PCUs from 2019 to 2021, comprising one urban and three suburban facilities. Using mixed effects logistic regression, we compared care factors between urban and suburban PCUs.

RESULTS

Patients attending suburban PCUs were significantly more likely to undergo eye (adjusted OR (AOR): 1.83, 95% CI 1.35 to 1.72), foot (AOR: 1.61, 95% CI 0.65 to 4.59) and HbA1c (AOR: 1.66, 95% CI 1.09 to 2.30) exams and achieved all ABC (HbA1c, blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C)) goals (AOR: 2.23, 95% CI 1.30 to 3.83). Conversely, those at an urban PCU were more likely to undergo albuminuria exams. Variables significantly associated with good glycaemic control included age (AOR: 1.51, 95% CI 1.31 to 1.79), T2DM duration (AOR: 0.59, 95% CI 0.41 to 0.88), FAACE (foot, HbA1c, albuminuria, LDL-C and eye) goals (AOR: 1.23, 95% CI 1.12 to 1.36) and All8Q (AOR: 1.20, 95% CI 1.05 to 1.41). Chronic kidney disease (CKD) was significantly linked with high triglyceride and HbA1c levels (AOR: 5.23, 95% CI 1.21 to 7.61). Elevated HbA1c levels, longer T2DM duration, insulin use, high systolic BP and high lipid profile levels correlated strongly with diabetic retinopathy (DR) and CKD progression.

CONCLUSION

This highlights the necessity for targeted interventions to bridge urban-suburban care gaps, optimise drug prescriptions and implement comprehensive care strategies for improved glycaemic control, DR prevention and CKD progression mitigation among in Thai patients with T2DM. The value of the clinical target aggregate (ABC) and the process of care aggregate (FAACE) was also conclusively demonstrated.

Association of carotid atherosclerosis markers with all-cause and cardiovascular disease-specific mortality in persons with type 2 diabetes: a causal mediation analysis with glucose variation

AIMS

Glucose variation (GV) is independently associated with mortality in patients with diabetes. However, no study has examined the effects of carotid atherosclerosis markers on mortality after considering GV. Our purpose is to investigate the independent effects of carotid atherosclerosis markers in persons with type 2 diabetes (T2DM) after considering GV and the mediation effects of carotid atherosclerosis markers on associations between GV with cardiovascular disease (CVD) mortality.

MATERIALS AND METHODS

This study is a retrospective cohort study including 3628 persons with T2DM who were admitted to a medical center between January 01, 2001 and October 31, 2021. GV was defined as a coefficient of variation (CV) of repeated measurements within a year before the index date (date of first IMT assessment). Carotid atherosclerosis markers included intima-media thickness (IMT), plaque, and stenosis. The outcomes consisted of all-cause and expanded cardiovascular disease (CVD) mortality. Cox proportional hazards models were applied.

RESULTS

Among the participants, 286 (7.9%) had IMT ≥ 2 mm, 2834 (78.1%) had carotid plaque, and 464 (12.8%) had carotid stenosis ≥ 50%. When GV was considered, IMT, carotid plaque, and carotid stenosis were significant factors for all-cause mortality (except IMT considering HbA1c-CV) and expanded CVD mortality. IMT was a significant mediator in the associations of fasting plasma glucose (FPG)-CV with all-cause and expanded CVD mortality (2 and 3.19%, respectively), and carotid stenosis was a significant mediator in the association between FPG-CV and expanded CVD mortality (3.83%).

CONCLUSIONS

Our statistical evaluations show suggests that carotid atherosclerosis markers are important predictors of CVD mortality in persons with T2DM if GV is considered. In addition, IMT and carotid stenosis were significant mediators in the association between GV and mortality.

Quality assessment of videos on social media platforms related to gestational diabetes mellitus in China: A cross-section study

Purpose

This study aimed to systematically evaluate the quality of content and information in videos related to gestational diabetes mellitus on Chinese social media platforms.

Methods

The videos on various platforms, TikTok, Bilibili, and Weibo, were searched with the keyword "gestational diabetes mellitus" in Chinese, and the first 50 videos with a comprehensive ranking on each platform were included for subsequent analysis. Characteristic information of video was collected, such as their duration, number of days online, number of likes, comments, and number of shares. DISCREN, JAMA (The Journal of the American Medical Association) Benchmark Criteria, and GQS (Global Quality Scores) were used to assess the quality of all videos. Finally, the correlation analysis was performed among video features, video sources, DISCERN scores, and JAMA scores.

Results

Ultimately, 135 videos were included in this study. The mean DISCERN total score was 31.84 ± 7.85, the mean JAMA score was 2.33 ± 0.72, and the mean GQS was 2.00 ± 0.40. Most of the videos (52.6%) were uploaded by independent medical professionals, and videos uploaded by professionals had the shortest duration and time online (P < 0.001). The source of the video was associated with numbers of "likes", "comments", and "shares" for JAMA scores (P < 0.001), but there was no correlation with DISCERN scores. Generally, videos on TikTok with the shortest duration received the most numbers of "likes", "comments", and "shares", but the overall quality of videos on Weibo was higher.

Conclusion

Although the majority of the videos were uploaded by independent medical professionals, the overall quality appeared to be poor. Therefore, more efforts and actions should be taken to improve the quality of videos related to gestational diabetes mellitus.

Changes in lipid profile and glucose metabolism following administration of bupropion alone or in combination with naltrexone: A systematic review and meta-regression analysis

BACKGROUND

Considering the conflicting effects of bupropion on parameters related to metabolic syndrome including glucose metabolism and lipid profile, in this meta-analysis study, we investigated the effects of this drug alone or in combination with naltrexone on glucose metabolism and lipid profile.

METHODS

Scopus, PubMed/Medline, Web of Science and Embase databases were searched using standard keywords to identify all controlled trials investigating effects of bupropion alone and combined with naltrexone on the glucose and lipid profile. Pooled weighted mean difference and 95% confidence intervals were achieved by random-effects model.

RESULTS

Twelve studies with 5152 participants' were included in this article. The pooled findings showed that bupropion alone or in combination with naltrexone would significantly reduce glucose (weighted mean difference (WMD): -2.25 mg/dL, 95% confidence interval (CI): -4.10, -0.40), insulin (WMD: -4.06 μU/mL, 95% CI: -6.09, -2.03), homeostatic model assessment for insulin resistance (HOMA-IR) (WMD: -0.58, 95% CI: -0.98, -0.19), triglyceride (TG) (WMD: -11.78 mg/dL, 95% CI: -14.48 to -9.08) and increase high-density lipoprotein (HDL) (WMD: 2.68 mg/dL, 95% CI: 2.13 to 3.24). A Greater reduction in glucose levels was observed with duration >26 weeks. Dose of bupropion intake ≤360 mg and intervention for more than 26 weeks decreased insulin level significantly. With regard to lipid profile, reduction of triglycerides is more significant with dose of bupropion greater than 360 mg and a shorter intervention length equal to 26 weeks.

CONCLUSIONS

The addition of combination therapies such as bupropion and naltrexone to lifestyle modification can significantly improve glucose metabolism and some lipid parameters.

DRAC 2022: A public benchmark for diabetic retinopathy analysis on ultra-wide optical coherence tomography angiography images

We described a challenge named "DRAC - Diabetic Retinopathy Analysis Challenge" in conjunction with the 25th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI 2022). Within this challenge, we provided the DRAC datset, an ultra-wide optical coherence tomography angiography (UW-OCTA) dataset (1,103 images), addressing three primary clinical tasks: diabetic retinopathy (DR) lesion segmentation, image quality assessment, and DR grading. The scientific community responded positively to the challenge, with 11, 12, and 13 teams submitting different solutions for these three tasks, respectively. This paper presents a concise summary and analysis of the top-performing solutions and results across all challenge tasks. These solutions could provide practical guidance for developing accurate classification and segmentation models for image quality assessment and DR diagnosis using UW-OCTA images, potentially improving the diagnostic capabilities of healthcare professionals. The dataset has been released to support the development of computer-aided diagnostic systems for DR evaluation.

Severity and Remission of Metabolic Dysfunction-Associated Fatty/Steatotic Liver Disease With Chronic Kidney Disease Occurrence

BACKGROUND

The association of the severity of hepatic steatosis in metabolic dysfunction-associated fatty liver disease (MAFLD)/metabolic dysfunction-associated steatotic liver disease (MASLD) and the remission of MAFLD/MASLD with CKD occurrence is unclear.

METHODS AND RESULTS

The study enrolled 79 540 participants from the Kailuan cohort. Hepatic steatosis was diagnosed by ultrasound. MAFLD/MASLD was defined as hepatic steatosis combined with metabolic dysfunction and MASLD further excluded alcohol or other causes of liver disease. Chronic kidney disease (CKD) was defined as estimated glomerular filtration rate<60 mL/min per 1.73 m2 or positive proteinuria (≥1+). Hazard ratio (HR) was calculated by Cox regression models. After a median follow-up of 12.9 years, CKD occurred in 20 465 participants. After adjusting for potential confounders, MAFLD was associated with a higher risk of CKD compared with non-MAFLD (HR, 1.12 [95% CI, 1.09-1.16]), and this risk increased with increasing severity of hepatic steatosis (P-trend<0.001). Consistent findings were observed when MASLD was used as the exposure. Compared with persistent non-MAFLD, no statistical difference was found in the risk of CKD in MAFLD remission (HR, 1.04 [95% CI, 0.95-1.15]); however, MASLD remission still had a higher risk of CKD compared with persistent non-MASLD (HR, 1.15 [95% CI, 1.03-1.27]). When grouped according to the prior severity of hepatic steatosis, there was no statistically significant difference in risk of CKD in mild-MAFLD/MASLD remission compared with persistent non-MAFLD/MASLD, but moderated/severe-MAFLD/MASLD remission still had a higher risk.

CONCLUSIONS

The risk of CKD in patients with MAFLD/MASLD increased with the severity of hepatic steatosis. Even after remission of the disease, patients with MAFLD/MASLD with prior moderate to severe hepatic steatosis still had a higher risk of CKD.

A Practical Approach to the Management of Residual Cardiovascular Risk: United Arab Emirates Expert Consensus Panel on the Evidence for Icosapent Ethyl and Omega-3 Fatty Acids

PURPOSE

Patients with hyperlipidemia treated with statins remain at a residual cardiovascular (CV) risk. Omega-3 polyunsaturated fatty acids hold the potential to mitigate the residual CV risk in statin-treated patients, with persistently elevated triglyceride (TG) levels.

METHOD

We reviewed the current evidence on the use of icosapent ethyl (IPE), an omega-3 fatty acid yielding a pure form of eicosapentaenoic acid.

RESULTS

REDUCE-IT reported a significant 25% reduction in CV events, including the need for coronary revascularization, the risk of fatal/nonfatal myocardial infarction, stroke, hospitalization for unstable angina, and CV death in patients on IPE, unseen with other omega-3 fatty acids treatments. IPE was effective in all patients regardless of baseline CV risk enhancers (TG levels, type-2 diabetes status, weight status, prior revascularization, or renal function). Adverse events (atrial fibrillation/flutter) related to IPE have occurred mostly in patients with prior atrial fibrillation. Yet, the net clinical benefit largely exceeded potential risks. The combination with other omega-3 polyunsaturated fatty acids, in particular DHA, eliminated the effect of EPA alone, as reported in the STRENGTH and OMEMI trials. Adding IPE to statin treatment seems to be cost-effective, especially in the context of secondary prevention of CVD, decreasing CV event frequency and subsequently the use of healthcare resources.

CONCLUSION

Importantly, IPE has been endorsed by 20 international medical societies as a statin add-on treatment in patients with dyslipidemia and high CV risk. Robust medical evidence supports IPE as a pillar in the management of dyslipidemia.

REPRESENTATION AND EXTRAPOLATION: EVIDENCE FROM CLINICAL TRIALS. THE QUARTERLY JOURNAL OF ECONOMICS 2024;139:575-635. [PMID: 38859982 PMCID: PMC11164133 DOI: 10.1093/qje/qjad036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

This article examines the consequences and causes of low enrollment of Black patients in clinical trials. We develop a simple model of similarity-based extrapolation that predicts that evidence is more relevant for decision-making by physicians and patients when it is more representative of the group being treated. This generates the key result that the perceived benefit of a medicine for a group depends not only on the average benefit from a trial but also on the share of patients from that group who were enrolled in the trial. In survey experiments, we find that physicians who care for Black patients are more willing to prescribe drugs tested in representative samples, an effect substantial enough to close observed gaps in the prescribing rates of new medicines. Black patients update more on drug efficacy when the sample that the drug is tested on is more representative, reducing Black-white patient gaps in beliefs about whether the drug will work as described. Despite these benefits of representative data, our framework and evidence suggest that those who have benefited more from past medical breakthroughs are less costly to enroll in the present, leading to persistence in who is represented in the evidence base.

Sex and Age Differences in the Association Between Metabolic Dysfunction-Associated Fatty Liver Disease and Heart Failure: A Prospective Cohort Study

BACKGROUND

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a risk factor for heart failure (HF) occurrence, but it remains unclear whether the association between MAFLD and HF differs in different sexes and ages.

METHODS

A total of 96 576 participants of Kailuan Study were included. MAFLD was defined as presence of hepatic steatosis and metabolic dysfunction and classified as mild and significant by ultrasound. Hazard ratios (HRs) were calculated by Cox regression models.

RESULTS

After a median follow-up of 14.0 years, 2939 participants developed HF. Adjusting for confounding factors, mild-MAFLD (HR, 1.27 [95% CI, 1.16-1.39]) and significant-MAFLD (HR, 1.45 [95% CI, 1.31-1.63]) were associated with a higher risk of HF in all participants, and the risk differed by sex (Pinteraction<0.05) and age (Pinteraction<0.001). Compared with non-MAFLD participants, in women, significant-MAFLD was associated with an 84% (HR, 1.84 [95% CI, 1.43-2.37]) increased risk of HF; however, in men, the risk was 36% (HR, 1.36 [95% CI, 1.20-1.53]). In participants under 45 years, mild-MAFLD and significant-MAFLD had a 55% (HR, 1.55 [95% CI, 1.07-2.25]) and 172% (HR, 2.72 [95% CI, 1.87-3.97]) increased risk of HF; however, in participants over 65 years, even significant-MAFLD did not associate with a higher risk of HF (HR, 1.11 [95% CI, 0.92-1.34]). Afterwards, we stratified all participants by both sex and age and found that the risk of MAFLD-associated HF decreased with age in men (Pinteraction<0.05) and women (Pinteraction<0.05), but the sex difference in this risk was only present in participants younger than 45 years (Pinteraction<0.05).

CONCLUSIONS

MAFLD greatly increased the risk of HF in women, especially young women. With increasing age, MAFLD-related risk of HF decreased and the difference between men and women disappeared.

Predictive value of serum TBA for 2-year MACEs in ACS patients undergoing PCI: a prospective cohort study

Bile acids play important roles in lipid metabolism and glucose homeostasis. Limited research exist on the association between serum total bile acid (TBA) levels and major adverse cardiovascular events (MACEs) in patients with acute coronary syndrome (ACS), particularly those with comorbid type 2 diabetes mellitus (T2DM). This study was conducted to examine the relationship between baseline serum TBA level and T2DM status in patients with ACS after percutaneous coronary intervention (PCI) and to identify the predictive value of TBA levels for a 2-year risk of MACEs. 425 ACS patients underwent PCI were recruited and divided into three groups based on baseline serum TBA concentration. An analysis of the association between the T2DM status and baseline serum TBA levels was conducted using univariate linear regression and multivariate linear regression. The predictive relevance of serum TBA levels was evaluated using the receiver operating characteristic (ROC) curve and Cox regression. Kaplan-Meier curves were employed to analyze the differences among groups in predicting MACEs over a 2-year follow-up period. Baseline serum TBA levels were higher in ACS patients who were diagnosed with T2DM (the median 3.6 µmol/L) than those without T2DM (the median 3.0 µmol/L). T2DM status in ACS patients was positively correlated with baseline serum TBA concentrations (β: 1.7, 95% confidence interval [CI] 0.3-3.0), particularly in the male (β: 2.0, 95% CI 0.3-3.6) and 50-69-year-old (β: 2.5, 95% CI 0.6-4.4) populations. The areas under the ROC curve of baseline serum TBA levels predicted MACEs in ACS and ACS-T2DM patients following PCI were 0.649 (95% CI 0.595-0.703) and 0.783 (95% CI 0.685-0.881), respectively. Furthermore, Cox regression analysis showed that baseline serum TBA level was associated with the occurrence of MACEs in patients with ACS after PCI over a 2-year follow-up period, especially in those diagnosed with T2DM, whose baseline TBA concentration was lower than 10.0 µmol/L. ACS Patients with T2DM had higher serum TBA levels. TBA level at baseline was an independent predictor of MACEs in ACS patients who underwent PCI, especially with comorbid T2DM.

Effects of glucagon-like peptide-1 receptor agonists on liver-related and cardiovascular mortality in patients with type 2 diabetes

BACKGROUND

Patients with type 2 diabetes (T2D) tend to have nonalcoholic fatty liver disease (NAFLD) with poorer prognosis. We performed this research to compare the risks of cardiovascular diseases, cirrhosis, liver-related mortality, and cardiovascular mortality between glucagon-like peptide-1 receptor agonist (GLP-1 RA) use and no-use in patients with T2D without viral hepatitis.

METHODS

From January 1, 2008, to December 31, 2018, we used propensity-score matching to identify 31,183 pairs of GLP-1 RA users and nonusers from Taiwan's National Health Insurance Research Database. Multivariable-adjusted Cox proportional hazards models were used to examine the outcomes between the study and control groups.

RESULTS

The median (Q1, Q3) follow-up time for GLP-1 RA users and nonusers were 2.19 (1.35, 3.52) and 2.14 (1.19, 3.68) years, respectively. The all-cause mortality incidence rate was 5.67 and 13.06 per 1000 person-years for GLP-1 RA users and nonusers, respectively. Multivariable-adjusted analysis showed that GLP-1 RA use had significantly lower risks of all-cause mortality (aHR 0.48, 95%CI 0.43-0.53), cardiovascular events (aHR 0.92, 95%CI 0.86-0.99), cardiovascular death (aHR 0.57, 95%CI 0.45-0.72), and liver-related death (aHR 0.32, 95%CI 0.13-0.75). However, there was no significant difference in the risk of liver cirrhosis development, hepatic failure, and hepatocellular carcinoma compared to GLP-1 RA no-use.

CONCLUSIONS

This nationwide cohort study showed that GLP-1 RA use was associated with a significantly lower risk of all-cause mortality, cardiovascular events, and cardiovascular death in patients with T2D among Taiwan population. More prospective studies are warranted to verify our results.

Sleeve gastrectomy and one-year outcomes: Impact on cardiovascular, renal and metabolic parameters

Background

Cardiovascular and renal diseases represent a major determinant for the morbidity and mortality associated with obesity and type 2 diabetes mellitus (T2DM). Bariatric surgery is considered one of the few treatments with the potential to reverse cardiovascular, renal and metabolic disease.

Methods

Prospective study of patients undergoing sleeve gastrectomy collecting pre- and post-surgery creatinine, eGFR, glucose, insulin, total, LDL/HDL cholesterol, triglycerides, parathyroid hormone, vitamin D3, C- Reactive Protein (CRP), blood count, weight, body mass index (BMI), bilateral carotid intima media thickness (IMT), flow-mediated dilation (FMD) and epicardial adipose tissue (EAT). Measurements were compared at 1 year follow up.

Results

24 patients were included in the study. Cardiovascular parameters, as HDL-cholesterol (p = 0.002), IMT (p = 0.003), EAT (p < 0.001) and FMD (p = 0.001) showed significant improvement after surgery. Secondary renal outcomes including Vitamin D3 (p < 0.0001), Calcium (p = 0.006), RBCs (p = 0.007), HCO3- (p = 0.05) also ameliorated as well as BMI (p < 0.001).

Conclusions

Sleeve gastrectomy has a positive impact on cardiovascular, renal, and metabolic parameters in patients with morbid obesity, suggesting it may halt the progression of these diseases even in the preclinical stage. Further research is needed to explore the long-term effects underlying these improvements.

Targeting mitochondrial quality control for diabetic cardiomyopathy: Therapeutic potential of hypoglycemic drugs

Diabetic cardiomyopathy is a chronic cardiovascular complication caused by diabetes that is characterized by changes in myocardial structure and function, ultimately leading to heart failure and even death. Mitochondria serve as the provider of energy to cardiomyocytes, and mitochondrial dysfunction plays a central role in the development of diabetic cardiomyopathy. In response to a series of pathological changes caused by mitochondrial dysfunction, the mitochondrial quality control system is activated. The mitochondrial quality control system (including mitochondrial biogenesis, fusion and fission, and mitophagy) is core to maintaining the normal structure of mitochondria and performing their normal physiological functions. However, mitochondrial quality control is abnormal in diabetic cardiomyopathy, resulting in insufficient mitochondrial fusion and excessive fission within the cardiomyocyte, and fragmented mitochondria are not phagocytosed in a timely manner, accumulating within the cardiomyocyte resulting in cardiomyocyte injury. Currently, there is no specific therapy or prevention for diabetic cardiomyopathy, and glycemic control remains the mainstay. In this review, we first elucidate the pathogenesis of diabetic cardiomyopathy and explore the link between pathological mitochondrial quality control and the development of diabetic cardiomyopathy. Then, we summarize how clinically used hypoglycemic agents (including sodium-glucose cotransport protein 2 inhibitions, glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, thiazolidinediones, metformin, and α-glucosidase inhibitors) exert cardioprotective effects to treat and prevent diabetic cardiomyopathy by targeting the mitochondrial quality control system. In addition, the mechanisms of complementary alternative therapies, such as active ingredients of traditional Chinese medicine, exercise, and lifestyle, targeting mitochondrial quality control for the treatment of diabetic cardiomyopathy are also added, which lays the foundation for the excavation of new diabetic cardioprotective drugs.

Bibliometric analysis of residual cardiovascular risk: trends and frontiers

BACKGROUND

The presence of residual cardiovascular risk is an important cause of cardiovascular events. Despite the significant advances in our understanding of residual cardiovascular risk, a comprehensive analysis through bibliometrics has not been performed to date. Our objective is to conduct bibliometric studies to analyze and visualize the current research hotspots and trends related to residual cardiovascular risk. This will aid in understanding the future directions of both basic and clinical research in this area.

METHODS

The literature was obtained from the Web of Science Core Collection database. The literature search date was September 28, 2022. Bibliometric indicators were analyzed using CiteSpace, VOSviewer, Bibliometrix (an R package), and Microsoft Excel.

RESULT

A total of 1167 papers were included, and the number of publications is increasing rapidly in recent years. The United States and Harvard Medical School are the leading country and institution, respectively, in the study of residual cardiovascular risk. Ridker PM and Boden WE are outstanding investigators in this field. According to our research results, the New England Journal of Medicine is the most influential journal in the field of residual cardiovascular risk, whereas Atherosclerosis boasts the highest number of publications on this topic. Analysis of keywords and landmark literature identified current research hotspots including complications of residual cardiovascular risk, risk factors, and pharmacological prevention strategies.

CONCLUSION

In recent times, global attention toward residual cardiovascular risk has significantly increased. Current research is focused on comprehensive lipid-lowering, residual inflammation risk, and dual-pathway inhibition strategies. Future efforts should emphasize strengthening international communication and cooperation to promote the comprehensive evaluation and management of residual cardiovascular risk.

The Clinical Value of the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy Score in Predicting Long-Term Major Adverse Cardiovascular And Cerebrovascular Events and Major Bleeding in Acute Coronary Syndrome Patients Who Underwent Percutaneous Coronary Intervention

The PRECISE-DAPT (predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy) score is recommended for predicting out-of-hospital bleeding after percutaneous coronary intervention (PCI). However, its long-term prediction remains unclear. We investigated the performance of this score in predicting long-term outcomes in patients with the acute coronary syndrome (ACS). We divided retrospectively enrolled patients (n = 1071) into two groups according to their PRECISE-DAPT scores: low < 25 and high ≥ 25. Bleeding was assessed using the Bleeding Academic Research Consortium criteria. The ischemic endpoints were all-cause death and major adverse cardiovascular and cerebrovascular events (MACCE). During follow-up (median 7.3 years), MACCE (55 vs 35%, P<.001) and major bleeding (9 vs 4%, P = .002) rates were greater in the high score group. The PRECISE-DAPT score was an independent predictor of MACCE in multivariate analysis (Hazard ratio [HR]: 1.028, 95% confidence interval [CI]: 1.016-1.039, P < .001). Also, the PRECISE-DAPT score predicted all-cause mortality (HR: 2.115, 95% CI: 1.508-2.965, P < .001) at long-term follow-up. The PRECISE-DAPT score may be useful for predicting MACCE at long-term follow-up in addition to the risk of bleeding.

Willingness for Medical Screening in a Dental Setting-A Pilot Questionnaire Study

An important way to manage noncommunicable diseases (NCDs) is to focus on prevention, early detection, and reducing associated risk factors. Risk factors can be detected with simple general health checks, which can also be performed in dental clinics. The purpose of this study was to investigate participants' willingness to participate in general health checks at the dentist, in particular the difference in opinion between medical patients and random healthy dental attendees. A total of 100 medical patients from an outpatient internal medicine clinic and 100 dental clinic attendees were included (total of 200 participants). The participants were asked for their opinion using six closed-ended questions. Overall, 91.0% of participants were receptive to information about the risk of diabetes mellitus (DM) and cardiovascular diseases (CVD). The majority (80-90%) was receptive to screening for DM and CVD risk, such as weight and height measurements, blood pressure measurement, saliva testing for CVD and to measure glucose and cholesterol via finger stick. No significant differences were found in the frequencies of the responses between the different groups based on health status, age, sex, or cultural background. This study shows that most participants are willing to undergo medical screening at the dentist for early detection and/or prevention of common NCDs.

A Type 1 Diabetes Polygenic Score Is Not Associated With Prevalent Type 2 Diabetes in Large Population Studies

Context

Both type 1 diabetes (T1D) and type 2 diabetes (T2D) have significant genetic contributions to risk and understanding their overlap can offer clinical insight.

Objective

We examined whether a T1D polygenic score (PS) was associated with a diagnosis of T2D in the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium.

Methods

We constructed a T1D PS using 79 known single nucleotide polymorphisms associated with T1D risk. We analyzed 13 792 T2D cases and 14 169 controls from CHARGE cohorts to determine the association between the T1D PS and T2D prevalence. We validated findings in an independent sample of 2256 T2D cases and 27 052 controls from the Mass General Brigham Biobank (MGB Biobank). As secondary analyses in 5228 T2D cases from CHARGE, we used multivariable regression models to assess the association of the T1D PS with clinical outcomes associated with T1D.

Results

The T1D PS was not associated with T2D both in CHARGE (P = .15) and in the MGB Biobank (P = .87). The partitioned human leukocyte antigens only PS was associated with T2D in CHARGE (OR 1.02 per 1 SD increase in PS, 95% CI 1.01-1.03, P = .006) but not in the MGB Biobank. The T1D PS was weakly associated with insulin use (OR 1.007, 95% CI 1.001-1.012, P = .03) in CHARGE T2D cases but not with other outcomes.

Conclusion

In large biobank samples, a common variant PS for T1D was not consistently associated with prevalent T2D. However, possible heterogeneity in T2D cannot be ruled out and future studies are needed do subphenotyping.

Associations between Oral Glucose-Lowering Agents and Increased Risk for Life-Threatening Arrhythmias in Patients with Type 2 Diabetes Mellitus-A Literature Review

Background and Objectives: The relationship between type 2 diabetes mellitus (T2DM) and cardiovascular (CV) morbidity and mortality is well-established. Ventricular arrhythmias (VA) are frequently diagnosed in patients with T2DM, especially in those with associated coronary syndrome, non-ischemic dilated cardiomyopathy (NIDCM), and heart failure (HF). In these patients, VA and sudden cardiac arrest (SCA) are considered responsible for more than 50% of CV deaths. Newly developed glucose-lowering agents (GLA) seem not only to ameliorate CV morbidity and mortality, but also to reduce the risk of VA and SCA. Materials and Methods: We researched the medical literature on Pub-Med, Clarivate, and Google Scholar for original articles published in the last five years that debated the possible effects of various GLA on ventricular arrhythmias. Results: We identified nineteen original articles, nine of them debating the antiarrhythmic effects of sodium-glucose cotransporter-2 inhibitors (SGLT2i); Conclusions: The results concerning the impact of various GLA on VA/SCA were heterogeneous depending on the pharmacological class studied, with some of them having neutral, positive, or negative effects. Although it appears that SGLT2i reduces the prevalence of atrial fibrillation and SCA, their effect on VA is not conclusive.

An Update on Semaglutide Research: A Bibliometric Analysis and a Literature Review

This study analyzes the most relevant authors, sources, cooccurrence of keywords, thematic map, and trend topics of the most recent and most cited research papers on semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA). Also, the content of the 25 most cited papers is summarized. A total of 2995 results appeared in an online electronic search performed on 14 August 2023 in the Scopus database using the term semaglutide. The most recently published 500 articles and most cited 200 documents were selected for bibliometric analysis. Network analysis visualization was conducted with the help of the VOSviewer software (version 1.6.18) (Centre for Science and Technology Studies, Leiden, the Netherlands) and Biblioshiny (it is a shiny application providing a web interface for bibliometrix) (Department of Economics and Statistics, University of Naples Federico II, Naples, Italy). After excluding duplicates and editorials, the data analysis found that 495 most recent documents were published in 279 journals by 2461 authors, and 200 most cited papers were published in 103 sources by 1241 authors. There is an increasing trend in the number of research papers from 2014 to 2022, with a peak in 2022. The most relevant authors in the most recent semaglutide research papers are Chen and Zhang. The pertinent authors of the most cited research papers on semaglutide are Lingvay and Khunti. The most common keywords used in the most recent and most cited research papers are semaglutide, obesity, diabetes mellitus type 2, glucagon-like peptide-1, glucagon-like peptide-1 receptor agonist, antidiabetic agent, liraglutide, and cardiovascular disease (CVD). The most relevant source is "Diabetes, Obesity and Metabolism" for the research papers on semaglutide. Trend topic analysis suggests that most of the research between 2020 and 2022 on semaglutide was done on non-insulin-dependent diabetes mellitus. The most cited papers provide essential insights into using semaglutide in managing type 2 diabetes mellitus (T2DM), obesity, and related conditions, along with their potential benefits, side effects, and possible mechanisms of action. This analysis highlights that the pharmacological effects of semaglutide extend beyond its role as a glycemic regulator.

Cardiovascular disease management in Australian adults with type 2 diabetes: insights from the CAPTURE study

BACKGROUND

Type 2 diabetes (T2D) is a well-recognised cardiovascular disease (CVD) risk factor, and recent guidelines for the management of T2D include consideration of CVD risk.

AIM

To assess whether contemporary clinical management of Australians with T2D is in accord with recent national and international guidelines.

METHODS

This Australia-specific analysis of the CAPTURE study, a non-interventional, cross-sectional study included adults diagnosed with T2D ≥180 days prior to providing informed consent and visiting primary or specialist care. Main outcome measures were the use of blood glucose-lowering medications (BGLMs), BGLMs with proven cardiovascular benefits and other CVD medications, stratified by CVD status and care setting.

RESULTS

Of 824 Australian participants in the CAPTURE sample, 332 (40.3%) had CVD. Oral BGLMs were used by 83.9% of all participants, most commonly metformin (76.0%), dipeptidyl peptidase-4 inhibitors (28.8%), sodium-glucose cotransporter-2 inhibitors (SGLT2is; 21.8%) and sulfonylureas (21.7%). Insulin was used by 29.2% of participants. BGLMs with proven CV benefit were used by 22.6%; glucagon-like peptide-1 receptor agonists (GLP-1 RAs) were less commonly used than SGLT2is in all CVD groups, but these drug classes were more often prescribed in specialist than primary care (SGLT2is 25.4 vs 20.7%, GLP-1 RAs 3.2 vs 0.8% respectively). Use of non-BGLMs for CVD risk reduction appeared consistent with guidelines.

CONCLUSIONS

Use of BGLMs with CVD benefits appears low in Australia, irrespective of CVD status. This likely reflects the delay in translation of clinical evidence into contemporary care and prescribing restrictions.

This article provides an in-depth review of the current state of management for diabetes, hypertension, and cardiovascular disease, focusing on advancements from genomics to robotics. It explores the role of genomic markers in personalized medicine, offering tailored treatment options for these chronic conditions. The article also examines the efficacy of various pharmacological and surgical interventions, including bariatric surgery for diabetes and device-based treatments for hypertension. A comparative analysis is presented to evaluate the cost-effectiveness and patient outcomes between medical and surgical approaches. The review concludes that while personalized medicine and minimally invasive surgical techniques show promise, more high-quality comparative research is needed. The ultimate goal is to integrate these emerging technologies within a framework of evidence-based medicine to improve patient outcomes and health equity.

Use of diabetes medications in adults with T2D and CVD in Japan: secondary analysis of the CAPTURE study

Introduction

The CAPTURE study estimated the global prevalence of established cardiovascular disease (CVD) and characterized the usage of glucose-lowering agents (GLAs) in adults with type 2 diabetes (T2D) across 13 countries. The purpose of this secondary analysis of data from the Japanese sites within CAPTURE (NCT03786406, NCT03811288) was to provide data about medication usage stratified by CVD status among Japanese participants with T2D.

Materials and methods

Data on GLA usage (including those with proven cardiovascular [CV] benefits) in Japanese participants with T2D managed in clinics or hospitals were collected and stratified by CVD subgroups.

Results

There were 800 Japanese participants in the CAPTURE study (n = 502 [no CVD group], n = 298 [CVD group], n = 268 [atherosclerotic CVD subgroup]). Oral antidiabetic agents and insulin were used by 88.5% and 23.4%, respectively, of participants overall. Among participants with established CVD, dipeptidyl peptidase-4 inhibitors (65.1%) were most frequently used, followed by biguanides (50.7%) and insulins (26.2%). The pattern was similar among participants with atherosclerotic CVD. A lower proportion of participants in the CVD group used glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT-2is) with proven CV benefits versus the no CVD group (GLP-1 RAs: 7.0% vs. 8.6%; SGLT-2is: 13.4% vs. 19.1%).

Conclusion

This analysis of the CAPTURE study provided a comprehensive overview of prescription patterns for the treatment of T2D in Japan. Use of GLAs with proven CV benefit was low, even in participants with established CVD, which was comparable to the findings from the global cohort.

Safety and Clinical Outcomes of Insulin Degludec in Korean Patients with Diabetes in Real-World Practices: A Prospective, Observational Study

INTRODUCTION

To investigate the safety and effectiveness of insulin degludec (IDeg) in a real-world population of Korean patients with diabetes requiring insulin therapy.

METHODS

This was a multicenter, prospective, single-arm, open-label, non-interventional study. Patients aged ≥ 12 months and treated with previous glucose-lowering medications were eligible to switch to IDeg. The primary endpoint was the incidence of adverse events (AEs), and the secondary endpoints were changes in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), postprandial glucose (PPG), and target HbA1c < 7.0%.

RESULTS

In total, 3225 and 2450 patients were included in the safety analysis set (SAS) and effectiveness analysis set (EAS), respectively. The mean baseline HbA1c and duration of diabetes were 9.4% and 13.0 years, respectively. Adverse events were reported in 740 patients (22.9%); the majority were mild and resolved. Significant improvements were observed in HbA1c, FPG, and PPG at week 26 (all p < 0.0001). The target of HbA1c < 7% was achieved in 22.2% of patients at week 26.

CONCLUSION

In real-world clinical practice, 26 weeks of IDeg treatment resulted in significant reductions in glycemic parameters with a low incidence of AEs in Korean patients with diabetes. No new safety signals were observed.

Optimal medical therapy improves outcomes in patients with diabetes mellitus and acute myocardial infarction

AIMS

We aimed to explored the association between the use of optimal medical therapy (OMT) in patients with myocardial infarction (AMI) and diabetes mellitus (DM) and clinical outcomes.

METHODS

Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome (BleeMACS) is an international registry that enrolled participants with acute coronary syndrome followed up for at least 1 year across 15 centers from 2003 to 2014. Baseline characteristics and endpoints were analyzed.

RESULTS

Among 3095 (23.2%) patients with AMI and DM, 1898 (61.3%) received OMT at hospital discharge. OMT was associated with significantly reduced mortality (4.3% vs. 10.8%, p < 0.001), re-AMI (4.4% vs. 8.1%, p < 0.001), and composite endpoint of death/re-AMI (8.0% vs. 17.6%, p < 0.001). No difference was observed among regions. Propensity score matching confirmed that OMT significantly associated with lower mortality. After adjusting for confounding variables, OMT, drug-eluting stents, and complete revascularization were independent protective factors of 1-year mortality, whereas left ventricular ejection fraction and age were risk factors.

CONCLUSIONS

Guideline-recommended OMT was prescribed at suboptimal frequencies with geographic variations in this worldwide cohort. OMT can improve long-term clinical outcomes in patients with DM and AMI.

Academic detailing as a method to improve general practitioners' drug prescribing in type 2 diabetes: evaluation of changes in prescribing

OBJECTIVE

To investigate the effect of an academic detailing intervention on the utilisation of type 2 diabetes medication among general practitioners.

DESIGN

We developed an academic detailing campaign based on the revised national treatment guideline for diabetes and the best available evidence. General practitioners were offered a 20-minute one-to-one visit by a trained academic detailer.

SETTING AND SUBJECTS

A total of 371 general practitioners received a visit and represented the intervention group. The control group consisted of 1282 general practitioners not receiving a visit.

MAIN OUTCOME MEASURES

Changes in prescribing from 12 months before to 12 months after the intervention. The primary endpoint was a change in metformin. Secondary endpoints were changes in other groups of Type 2 diabetes medication and of these drugs in total.

RESULTS

Prescribing of metformin increased by 7.4% in the intervention group and 5.2% in the control group (p = .043). Sodium-glucose cotransporter-2 inhibitors increased by 27.6% in the intervention group and 33.8% in the control group (p = .019). For sulfonylureas there was a decrease of 3.6% in the intervention group vs. 8.9% in the control group (p = .026). The total amount of prescribed medications for type 2 diabetes increased by 9.1% in the intervention group and 7.3% in the control group (p = .08).

CONCLUSION

Academic detailing initiated a small but statistically significant increase in the prescription of metformin. For a complex subject like type 2 diabetes, we recommend reserving more time in the visit than the 20 min our campaign aimed for.

Effect modification of the association between temperature variability and hospitalization for cardiovascular disease by comorbid diabetes mellitus: A nationwide time-stratified case-crossover analysis

AIMS

We aimed to explore the association between short-term exposure to temperature variability (TV), and cardiovascular hospitalization stratified by the presence of comorbid diabetes.

METHODS

We collected data on nationwide hospitalization for cardiovascular diseases and daily weather conditions during 2011-2018 in Japan. TV was calculated as the standard deviation of daily minimum and maximum temperatures within 0-7 lag days. We applied a two-stage time-stratified case-crossover design to estimate the association between TV and cardiovascular hospitalization with and without comorbid diabetes, adjusting for temperature and relative humidity. Furthermore, specific cardiovascular disease causes, demographic characteristics, and seasons were used for stratification.

RESULTS

In 3,844,910 hospitalizations for cardiovascular disease, each 1 °C increase in TV was associated with a 0.44% (95% CI: 0.22%, 0.65%) increase in the risk of cardiovascular admission. We observed a 2.07% (95% CI: 1.16%, 2.99%) and 0.61% (95% CI: -0.02%, 1.23%) increase per 1 °C in risk of heart failure admission in individuals with and those without diabetes, respectively. The higher risk among individuals with diabetes was mostly consistent in the analyses stratified by age, sex, body mass index, smoking status, and season.

CONCLUSION

Comorbid diabetes may increase susceptibility to TV in relation to acute cardiovascular disease hospitalization.

Effects of Nondipping Blood Pressure Changes: A Nephrologist Prospect

Blood pressure (BP) variations depend on various internal, environmental, and behavioral factors. BP fluctuations occur both in normotensive and hypertensive people. Although it fluctuates over the 24-hr day and night, the morning BP increases after waking up and declines throughout sleep. It is typical for BP to decrease by 10% to 20%, while sleeping, known as dipping BP. However, if there is no decrease in nighttime mean systolic BP or a drop of less than 10 mmHg, it is called nondipping BP. Conversely, reverse dipping BP means an increase in mean systolic BP instead of a drop during the night. Reverse dipping is observed in hypertension (HTN), diabetes mellitus (DM), chronic kidney disease (CKD), and obstructive sleep apnea (OSA) syndrome. The introduction of ambulatory BP monitoring (ABPM) led to the emergence of identifying normal and elevated BP patterns. Non-dipping BP increases the risk of cardiovascular system (CVS) complications such as left ventricular hypertrophy, proteinuria, glomerular filtration rate (GFR) reduction, and CKD progression. A loss or blunting of the normal BP profile is recognized as a deleterious variant, and restoring abnormal BP patterns has been reported to significantly impact end-organ damage, morbidity, and mortality. In this non-systematic clinically-oriented, comprehensive review, we aim to update the BP variables and the pathophysiology of nondipping BP and point out the areas which need more investigation from a nephrology perspective because the nondipping BP increases the risk of proteinuria, GFR reduction, and CKD progression. A literature search of PubMed, Google, EMBASE, and Google Scholar was conducted. Checks of selected papers and relevant reviews complemented the electronic search. With improved BP measurement methods, the physiology of BP profile variations is readily detectable during the day and night. A nondipping BP profile is a distinct BP pattern that may have significant end-organ damage effects and therapeutic importance for nephrologists. The pathophysiology of the nondipping BP variant must be clarified to prevent complications, and further investigations are required. Furthermore, there is debate about the best BP index to utilize: systolic BP, diastolic BP, mean arterial pressure, or a mixture of all. All these areas are important and need new research projects.

Type 1 Diabetes and Aging

The number of older adults with type 1 diabetes (T1D) is increasing due to an overall increase in life expectancy and improvement in diabetes management and treatment of complications. They are a heterogeneous cohort due to the dynamic process of aging and the presence of comorbidities and diabetes-related complications. A high risk for hypoglycemia unawareness and severe hypoglycemia has been described. Periodic assessment of health status and adjustment of glycemic goals to mitigate hypoglycemia is imperative. Continuous glucose monitoring, insulin pump, and hybrid closed-loop systems are promising tools to improve glycemic control and mitigate hypoglycemia in this age group.

Time, Technology, Social Support, and Cardiovascular Health of Emerging Adults With Type 1 Diabetes

BACKGROUND

Emerging adults with Type 1 diabetes (T1DM) face an increased risk of cardiovascular disease; however, there are both barriers and facilitators to achieving ideal cardiovascular health in this stage of their lives.

OBJECTIVES

The aim of this study was to qualitatively explore the barriers and facilitators of achieving ideal levels of cardiovascular health in a sample of emerging adults with T1DM ages 18-26 years.

METHODS

A sequential mixed-methods design was used to explore achievement of ideal cardiovascular health using the seven factors defined by the American Heart Association (smoking status, body mass index, physical activity, healthy diet, total cholesterol, blood pressure, and hemoglobin A1C [substituted for fasting blood glucose]). We assessed the frequency of achieving ideal levels of each cardiovascular health factor. Using Pender's health promotion model as a framework, qualitative interviews explored the barriers and facilitators of achieving ideal levels of each factor of cardiovascular health.

RESULTS

The sample was mostly female. Their age range was 18-26 years, with a diabetes duration between 1 and 20 years. The three factors that had the lowest achievement were a healthy diet, physical activity at recommended levels, and hemoglobin A1C of <7%. Participants described lack of time as a barrier to eating healthy, being physically active, and maintaining in-range blood glucose levels. Facilitators included the use of technology in helping to achieve in-range blood glucose and social support from family, friends, and healthcare providers in maintaining several healthy habits.

DISCUSSION

These qualitative data provide insight into how emerging adults attempt to manage their T1DM and cardiovascular health. Healthcare providers have an important role in supporting these patients in establishing ideal cardiovascular health at an early age.

Safety, pharmacokinetics, and pharmacodynamics of TG103, a novel long-acting GLP-1/Fc fusion protein after a single ascending dose in Chinese healthy subjects

BACKGROUND AND OBJECTIVE

TG103 is a novel GLP-1/Fc fusion protein, developed for the treatment of type 2 diabetes and obesity. This trial was designed to assess the safety and tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) profiles after single ascending dose of TG103 in healthy Chinese subjects.

METHOD

In this double-blind, randomized, placebo-controlled phase I study, Chinese healthy subjects were admitted consecutively to TG103 3 mg, 7.5 mg, 15 mg, and 22.5 mg group with 8 subjects per group and randomized in a 3:1 ratio to receive TG103 treatment or placebo. Following a single subcutaneous(s.c.) injections of TG103, safety and tolerability were evaluated and blood samples were collected for PK and PD analysis at the specified time-points.

RESULT

Overall, 32 healthy subjects were enrolled and completed the study. During the study, a total of 84 adverse effects (AEs) were reported in 25 subjects, all were mild or moderate and resolved spontaneously without intervention. The most common treatment related AEs in TG103 group were decreased appetite (41.7%), nausea, flatulence, elevated urinary β2-microglobulin, increased serum total bile acid (20.8% each), decreased high-density lipoprotein (16.7%), abdominal distension (12.5%). After a single s.c. administration of TG103 3-22.5 mg, the median T_max was 36∼48 hours, and mean t_1/2 was about 147.16∼184.72 hours. The mean C_max for each group was 94.35±52.19, 337.67±56.71, 757.67±206.99, 1236.33±666.25 ng/mL, with AUC_0-t of 14.93±7.67, 59.15±7.39, 91.79±20.41, 163.61±55.99 μg·h/mL, respectively. It showed a linear pharmacokinetic profile in the single dose of TG103 3 mg to 22.5 mg. Compared with placebo, fasting blood glucose decreased in all dose groups, most notably in the 15 mg group, which was consistent with the changes in blood glucose during OGTT, while 2-hour postprandial glucose decreased in all dose groups except 3 mg group.

CONCLUSION

TG103 offers a potential option for hypoglycemic therapy with good tolerability and safety.

Diabetes mellitus status modifies the association between N-terminal B-type natriuretic peptide and all-cause mortality risk in ischemic heart failure: a prospective cohort study

BACKGROUND

N-terminal B-type natriuretic peptide (NT-proBNP) discriminates mortality risk in diabetes mellitus (DM) and in heart failure (HF) populations. Whether DM status modifies the association between NT-proBNP and all-cause mortality risk in ischemic HF is unknown.

METHODS

This was a single-center, prospective cohort study conducted with 2287 ischemic HF patients. Subjects were divided into with DM group and without DM group. Multivariate Cox proportional-hazards models were conducted to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs). The product of DM status and NT-proBNP were used to assess the interaction. Propensity score matching analysis was used to verify the robustness of the results.

RESULTS

Of 2287 ischemic HF participants, 1172 (51.2%) had DM. After a median follow-up of 3.19 years (7287 person-years), 479 (20.9%) of the participants died. After adjusting for the covariates, continuous NT-proBNP was more prominently associated with risk of mortality in HF patients with DM (HR: 1.65, 95% CI: 1.43-1.91) than those without (HR: 1.28, 95% CI: 1.09-1.50). A significant interaction of DM status and NT-proBNP was observed (P-interaction = 0.016). The relationships were consistent when NT-proBNP was considered as a categorical variable and in the propensity matching analysis.

CONCLUSIONS

DM status modified the association between NT-proBNP and all-cause mortality in ischemic HF patients, suggesting that NT-proBNP was more prominently associated with risk of mortality in patients with DM than those without. Future studies to clarify the mechanisms underlying these observations are needed.

Cardiovascular disease prevalence in adults with type 2 diabetes in Japan: results from the Japanese centers in the CAPTURE study

Introduction

CAPTURE was a cross-sectional, non-interventional study (NCT03786406, NCT03811288) investigating the prevalence and characteristics of cardiovascular disease (CVD) in adults with type 2 diabetes (T2D) across 13 countries worldwide. Here we present the findings for Japan.

Materials and methods

Data were collected from adults aged ≥ 20 years (aged ≥ 18 years in countries outside Japan) with T2D who were managed in clinics or hospitals in 2019. Standardized methodology was used for all countries. The prevalence of CVD and its subtypes was estimated, weighted by care setting (clinics versus hospitals).

Results

Among participants from Japan (total: 800; clinics: 440; hospitals: 360), mean (standard deviation) age was 65.6 (11.2) years and glycated hemoglobin 7.2% (0.9). Sixty-seven percent of participants were male, 57.8% had diabetes duration > 10 years, 49.8% had body mass index ≥ 25 kg/m2 and 63.1% had hypertension. The weighted prevalences (95% confidence interval [CI]) of CVD and atherosclerotic CVD were 37.3% (34.2;40.3) and 33.5% (30.6;36.4), respectively. The prevalence (95% CI) of the most common subtypes of CVD was: carotid artery disease 20.5% (18.2;22.8), coronary heart disease 11.9% (9.7;14.1) and cerebrovascular disease 10.4% (8.3;12.5).

Conclusions

These contemporary data from the CAPTURE study on CVD prevalence in adults with T2D in Japan show that approximately one in three adults with T2D had established CVD, which is comparable to the prevalence in the global study cohort.

Prediction of microvascular complications in diabetic patients without obstructive coronary stenosis based on peri-coronary adipose tissue attenuation model

OBJECTIVES

To investigate the predictive value of peri-coronary adipose tissue (PCAT) attenuation for microvascular complications in diabetic patients without significant stenosis and to develop a prediction model for early risk stratification.

METHODS

This study retrospectively included patients clinically identified for coronary computed tomography angiography (CCTA) and type 2 diabetes between January 2017 and December 2020. All patients were followed up for at least 1 year. The clinical data and CCTA-based imaging characteristics (including PCAT of major epicardial vessels, high-risk plaque features) were recorded. In the training cohort comprising of 579 patients, two models were developed: model 1 with the inclusion of clinical factors and model 2 incorporating clinical factors + RCA_PCAT using multivariable logistic regression analysis. An internal validation cohort comprising 249 patients and an independent external validation cohort of 269 patients were used to validate the proposed models.

RESULTS

Microvascular complications occurred in 69.1% (758/1097) of the current cohort during follow-up. In the training cohort, model 2 exhibited improved predictive power over model 1 based on clinical factors (AUC = 0.820 versus 0.781, p = 0.003) with lower prediction error (Brier score = 0.146 versus 0.164) compared to model 1. Model 2 accurately categorized 78.58% of patients with diabetic microvascular complications. Similar performance of model 2 in the internal validation cohort and the external validation cohort was further confirmed.

CONCLUSIONS

The model incorporating clinical factors and RCA_PCAT predicts the development of microvascular complications in diabetic patients without significant coronary stenosis.

KEY POINTS

• Hypertension, HbA1c, duration of diabetes, and RCA_PCAT were independent risk factors for microvascular complications. • The prediction model integrating RCA_PCAT exhibited improved predictive power over the model only based on clinical factors (AUC = 0.820 versus 0.781, p = 0.003) and showed lower prediction error (Brier score=0.146 versus 0.164).

Clinical outcomes by atherosclerotic cardiovascular disease risk score and blood pressure level in high risk individuals with type 2 diabetes

Clinical practice guidelines for patients with diabetes recommend using blood pressure (BP) and atherosclerotic cardiovascular disease (ASCVD) risk to guide antihypertensive treatment. While this approach directs treatment to patients who should receive a large ASCVD risk reduction, its effect on other outcomes is uncertain. The aim of this study was to assess the contributions of systolic blood pressure level (SBP) and predicted 10-year ASCVD risk using Pooled Cohort risk equations to the prediction of major macrovascular disease, death and major microvascular disease in patients with diabetes. Data came from 7426 individuals with type 2 diabetes (T2D) without macrovascular disease at baseline in the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) trial. The risk for major macrovascular events and death increased progressively across ASCVD risk categories. Compared to participants with 10-year predicted ASCVD risk <20% and SBP <130 mmHg, the hazard ratios (HRs) (95% confidence intervals (CIs)) associated with SBP ≥150 mmHg and 10-year predicted ASCVD risk <20%, 20-34% and ≥35% were 1.01 (0.58, 1.77), 1.90 (1.28, 2.84) and 2.82 (1.98, 4.01) for major macrovascular disease, respectively, and 0.83 (0.42, 1.62), 1.79 (1.13, 2.82) and 3.29 (2.22, 4.88) for death, respectively. The risk for major microvascular disease increased with BP regardless of ASCVD risk; HRs for SBP ≥150 mmHg and 10-year predicted ASCVD risk <20%, 20-34% and ≥35% vs. ASCVD risk <20% and SBP <130 mmHg were 1.52 (1.08,2.13), 1.47 (1.10, 1.96) and 1.23 (0.94, 1.60), respectively. ASCVD risk in addition to SBP improved the estimation of major macrovascular events and death but not major microvascular events among individuals with T2D.

Efficacy and safety of janagliflozin as add-on therapy to metformin in Chinese patients with type 2 diabetes inadequately controlled with metformin alone: A multicentre, randomized, double-blind, placebo-controlled, phase 3 trial

AIM

To evaluate the efficacy and safety of janagliflozin in Chinese patients with type 2 diabetes (T2D) inadequately controlled with metformin monotherapy.

MATERIALS AND METHODS

This multicentre phase 3 trial included a 24-week, randomized, double-blind, placebo-controlled period, followed by a 28-week extension period. Patients (N = 421) with HbA1c of 7.0% or higher and 10.5% or less were randomized (1:1:1) to receive once-daily placebo, janagliflozin 25 or 50 mg. After the 24-week treatment period, patients on placebo were re-randomized (1:1) to janagliflozin 25 or 50 mg for the additional 28-week treatment, whereas patients on janagliflozin maintained the same therapy. The primary endpoint was the change from baseline in HbA1c to week 24.

RESULTS

At week 24, the placebo-adjusted least squares mean changes of HbA1c were -0.58% and -0.58% with janagliflozin 25 and 50 mg, respectively (P < .0001 for both). The proportion of patients achieving HbA1c less than 7.0% was higher with janagliflozin 25 and 50 mg compared with placebo (41.8%, 41.7% and 28.0%, respectively). Both janagliflozin doses provided significant reductions in fasting plasma glucose, 2-hour postprandial glucose, body weight and systolic blood pressure, and improvements in high-density lipoprotein cholesterol and insulin sensitivity compared with placebo (P < .05 for all). The trends in improvement of these variables were retained during the 28-week extension period. No severe hypoglycaemia occurred throughout the whole 52-week treatment.

CONCLUSIONS

Janagliflozin 25 or 50 mg once-daily added to metformin therapy significantly improved glycaemic control, reduced body weight and systolic blood pressure, improved high-density lipoprotein cholesterol and insulin sensitivity, and was generally well-tolerated by Chinese T2D patients who had poor glycaemic control with metformin monotherapy.

Connections between Diabetes Mellitus and Metabolic Syndrome and the Outcome of Cardiac Dysfunctions Diagnosed during the Recovery from COVID-19 in Patients without a Previous History of Cardiovascular Diseases

(1) Background: Throughout the COVID-19 pandemic, it became obvious that individuals suffering with obesity, diabetes mellitus (T2DM), and metabolic syndrome (MS) frequently developed persisting cardiovascular complications, which were partially able to explain the onset of the long-COVID-19 syndrome. (2) Methods: Our aim was to document, by transthoracic echocardiography (TTE), the presence of cardiac alterations in 112 patients suffering from post-acute COVID-19 syndrome and T2DM, MS, and/or obesity, in comparison to 91 individuals without metabolic dysfunctions (MD); (3) Results: in patients with MD, TTE borderline/abnormal left (LVF) and/or right ventricular function (RVF), alongside diastolic dysfunction (DD), were more frequently evidenced, when compared to controls (p ˂ 0.001). Statistically significant associations between TTE parameters and the number of factors defining MS, the triglyceride-glucose (TyG) index, the severity of the SARS-CoV-2 infection, and the number of persisting symptoms (p ˂ 0.001) were noted. Significant predictive values for the initial C-reactive protein and TyG index levels, both for the initial and the 6-month follow-up levels of these TTE abnormalities (p ˂ 0.001), were highlighted by means of a multivariate regression analysis. (4) Conclusions: in diabetic patients with MS and/or obesity with comorbid post-acute COVID-19 syndrome, a comprehensive TTE delineates various cardiovascular alterations, when compared with controls. After 6 months, LVF and RVF appeared to normalize, however, the DD—although somewhat improved—did persist in approximately a quarter of patients with MD, possibly due to chronic myocardial changes.

Trajectory of glycated haemoglobin over time, using real-world data, in type 2 diabetes patients with obesity on a U-100 basal-bolus insulin regimen

AIMS

To identify patient clusters with poor glucose control among type 2 diabetes mellitus (T2DM) patients with obesity who are receiving basal-bolus insulin and to identify the potential therapeutic inertia factors associated with poor control.

METHODS

Glycated haemoglobin (HbA1c) trajectories across a 3-year period were structured at 6-month intervals for a retrospective cohort of T2DM patients with obesity on basal-bolus insulin from the Veterans' Health Administration database. Based on each patient's longitudinal HbA1c features, an unsupervised clustering procedure was used to determine the numbers of clusters and associated trajectory patterns. Multinomial logistic regression was used to examine the association between HbA1c trajectory clusters and patient characteristics/treatment patterns.

RESULTS

A total of 51 273 patients were included, of whom 11.2% were in a subgroup with persistent missingness of HbA1c values. For those with sufficient HbA1c observations, cluster analysis indicated six distinct HbA1c trajectories: stable low (35.8%); stable high (20.8%); descending low (10.5%); ascending low (10.2%); descending high (5.7%); and ascending high (5.7%). Being of Black ethnicity, not initiating noninsulin antihyperglycaemic agents (sodium-glucose cotransporter-2 inhibitors, glucagon-like peptide-1 receptor agonists or thiazolidinediones) or concentrated insulin, low adherence (measured by proportion of days covered), and reduced insulin prescription refills were factors associated with poorer HbA1c clusters; similar factors were associated with persistent HbA1c missingness.

CONCLUSION

The present study found the potential for therapeutic inertia among a significant proportion of T2DM patients with obesity on basal-bolus insulin. Subgrouping T2DM patients based on HbA1c missingness and HbA1c trajectories can inform disease management strategies.

A cross-sectional study of the prevalence and clinical management of atherosclerotic cardiovascular diseases in patients with type 2 diabetes across the Middle East and Africa (PACT-MEA): Study design and rationale

AIM

To investigate the epidemiology and clinical management of patients with type 2 diabetes (T2D) and established atherosclerotic cardiovascular disease (eASCVD) or high/very high ASCVD risk, defined by the 2021 European Society of Cardiology Guidelines, in seven countries in the Middle East and Africa (PACT-MEA; NCT05317845), and to assess physicians' attitudes and the basis for their decision-making in the management of these patients.

MATERIALS AND METHODS

PACT-MEA is a cross-sectional, observational study undertaken in Bahrain, Egypt, Jordan, Kuwait, Qatar, South Africa and the United Arab Emirates based on a medical chart review of approximately 3700 patients with T2D in primary and secondary care settings, and a survey of approximately 400 physicians treating patients with T2D.

RESULTS

The primary and secondary objectives are to determine the prevalence of eASCVD and high/very high ASCVD risk in patients with T2D. Current treatment with cardioprotective antidiabetic medication, the proportion of patients meeting the treatment criteria for reimbursement in the study countries where there is an applicable reimbursement guideline, and physician-reported factors in clinical decision-making in T2D management, will also be assessed.

CONCLUSIONS

This large cross-sectional study will establish the estimated prevalence and management of eASCVD and high/very high ASCVD risk in patients with type 2 diabetes across the Middle East and Africa.

Adherence to European guidelines for the use of aspirin in primary health care

INTRODUCTION AND OBJECTIVES

Cardiovascular disease remains a leading cause of global morbidity and mortality. The administration of low doses of aspirin in secondary prevention of atherosclerotic cardiovascular disease (ASCVD) has been clearly established. However, the most recent guidelines do not recommend aspirin in primary prevention, reserving it for high-risk patients and after a risk/benefit assessment. The aim of this study was to assess adherence to European guidelines for the use of aspirin in primary and secondary prevention of ASCVD in primary health care.

METHODS

The study population consisted of individuals aged >50 years registered at two primary health care units without (primary prevention) and with (secondary prevention) previous ASCVD events.

RESULTS

We studied a total of 1262 individuals, 720 in primary prevention and 542 in secondary prevention. A total of 61 individuals (8.5%) were under aspirin therapy in primary prevention, most of them taking 150 mg/day (57%). In secondary prevention, 195 patients (27%) were receiving aspirin only, most taking 150 mg/day (52%), and 166 patients (31%) were not under any antithrombotic or anticoagulant therapy. The 100 mg dosage was predominant in patients with ischemic heart disease with (64%) and without (64%) angina, as well as those with myocardial infarction (61.5%) and peripheral vascular disease (62%).

CONCLUSIONS

In this study, the prevalence of aspirin use in primary prevention was 8.5%. We found that 30% of patients were not taking either antithrombotic or anticoagulation therapy in secondary prevention. In both primary and secondary prevention, the 150 mg dosage was predominant.

Reducing Infection Rates with Enhanced Preoperative Diabetes Mellitus Diagnosis and Optimization Processes

OBJECTIVES

Hyperglycemia and increased preoperative hemoglobin A1c (HbA1c) are associated with perioperative morbidity and death. For nonurgent operations, adequate glycemic control before surgery is recommended. Our surgical practice needed a process for preoperative diabetes mellitus (DM) diagnosis and glycemic optimization.

METHODS

Our review of the existing preoperative evaluation process found that patients without a DM diagnosis but with random plasma glucose ≥200 mg/dL received no additional screening. Patients with DM routinely receive neither preoperative HbA1c screening nor DM management when HbA1c is ≥8.0%.

RESULTS

A new preoperative evaluation process was designed. HbA1c screening was automatically performed for patients with random plasma glucose ≥200 mg/dL. For patients with a DM diagnosis, an HbA1c test was performed. Specialty consultation was prompted for patients with known DM and HbA1c ≥8.0% and those with no DM diagnosis but HbA1c ≥6.5%. In the first year postimplementation, 9320 patients received a basic metabolic panel; 263 had random plasma glucose ≥200 mg/dL that triggered an HbA1c check. In total, 123 patients (99 with and 24 without a DM diagnosis) were referred to endocrinology; 13 received a new DM diagnosis. Twenty patients had surgery delayed for DM treatment. All of the patients received individualized medication instructions for the perioperative period. Among patients with random plasma glucose ≥200 mg/dL, incidence rates for surgical site infection pre- and postimplementation were 47.8/1000 and 3.8/1000 population.

CONCLUSIONS

The implemented process benefited patients scheduled for nonurgent procedures by optimizing glucose control and lowering infection rates through earlier preoperative DM diagnosis, glycemic management, and standardized patient medication instruction.

Clinical cardiovascular phenotypes and the pattern of future events in patients with type 2 diabetes

IMPORTANCE

Updated guidelines on diabetes recommend targeting sodium-glucose cotransporter-2 inhibitors (SGLT2i) at patients at risk of heart failure (HF) and glucagon-like peptide-1 receptor agonists (GLP1-RA) at those at greater risk of atherothrombotic events.

OBJECTIVE

We estimated the risk of different cardiovascular events in patients with type 2 diabetes (T2D) and newly established cardiovascular disease.

DESIGN, SETTING AND PARTICIPANTS

Patients with T2D and newly established cardiovascular disease from 1998 to 2016 were identified using Danish healthcare registers and divided into one of four phenotype groups: (1) HF, (2) ischemic heart disease (IHD), (3) transient ischemic stroke (TIA)/ischemic stroke, and (4) peripheral artery disease (PAD). The absolute 5-year risk of the first HF- or atherothrombotic event occurring after inclusion was calculated, along with the risk of death.

MAIN OUTCOMES AND MEASURES

The main outcome was the first event of either HF or an atherothrombotic event (IHD, TIA/ischemic stroke or PAD) in patients with T2D and  new-onset cardiovascular disease.

RESULTS

Of the 37,850 patients included, 40% were female and the median age was 70 years. Patients with HF were at higher 5-year risk of a subsequent HF event (17.9%; 95% confidence interval (CI) 17.1-18.8%) than an atherothrombotic event (15.8%; 15.0-16.6%). Patients with IHD were at higher risk of a subsequent atherothrombotic event (24.6%; 23.9-25.3%) than developing HF, although the risk of HF was still substantial (10.6%; 10.2-11.1%). Conversely, patients with PAD were at low risk of developing HF (4.4%; 3.8-5.1%) but at high risk of developing an atherothrombotic event (15.9%; 14.9-17.1%). Patients with TIA/ischemic stroke had the lowest risk of HF (3.2%; 2.9-3.6%) and the highest risk of an atherothrombotic event (20.6%; 19.8-21.4).

CONCLUSIONS

In T2D, a patient's cardiovascular phenotype can help predict the pattern of future cardiovascular events.

Pros and Cons of Long-Chain Omega-3 Polyunsaturated Fatty Acids in Cardiovascular Health

The long-chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found in seafood, supplements, and concentrated pharmaceutical preparations. Prospective cohort studies demonstrate an association between higher intakes of EPA+DHA or higher levels of EPA and DHA in the body and lower risk of developing cardiovascular disease (CVD), especially coronary heart disease and myocardial infarction, and of cardiovascular mortality in the general population. The cardioprotective effect of EPA and DHA is due to the beneficial modulation of a number of risk factors for CVD. Some large trials support the use of EPA+DHA (or EPA alone) in high-risk patients, although the evidence is inconsistent. This review presents key studies of EPA and DHA in the primary and secondary prevention of CVD, briefly describes potential mechanisms of action, and discusses recently published RCTs and meta-analyses. Potential adverse aspects of long-chain omega-3 fatty acids in relation to CVD are discussed.

Longitudinal association of ECG abnormalities with major adverse cardiac events in people with type 2 diabetes: The Hoorn Diabetes Care System cohort

AIMS

To investigate the association of (changes in) ECG abnormalities with incident major adverse cardiac events (MACE) in people with type 2 diabetes (T2D) without pre-existing cardiovascular disease (CVD).

METHODS

A prospective longitudinal study of 11,993 people with T2D without known CVD from the Hoorn Diabetes Care System cohort. Annually repeated measurements (1998-2018), included cardiovascular risk factors, over 70,000 ECGs, and self-reported cardiovascular events. ECG abnormalities were classified according to the Minnesota Classification as prolonged PR duration, prolonged QRS duration, left QRS-axis, QS pattern, ST-segment/T-wave abnormalities, or tall R-wave. The association of ECG abnormalities with MACEs was assessed using time-dependent Cox-regression models, adjusted for time-varying cardiovascular risk factors and medication use (Hazzard Ratios with 95%CIs).

RESULTS

During a median follow-up of 6.6 (IQR, 3.1-10.7) years, 5445 (45.4%) of the participants had an ECG abnormality (prevalent or incident) at any of the median 6 (IQR, 3-10) annual ECG recordings, and 905 people (7.5%) had a MACE (529 CHD, 250 HF, 126 SCA). After adjustment, most ECG abnormalities were associated with HF: prolonged QRS duration (HR, 4.01 (95%CI, 2.67-6.03)), QS pattern (2.68 (0.85-8.49)), ST-segment/T-wave abnormalities (4.26 (2.67-6.80)), and tall R-wave (2.23 (1.33-3.76)). Only QS pattern (2.69 (1.20-6.03)), and ST-segment/T-wave abnormalities (2.11 (1.48-3.02)) were associated with CHD. These associations were robust across age, sex, hypertension, or estimated CVD risk subgroups.

CONCLUSION

In people with T2D without pre-existing cardiovascular disease, ECG abnormalities related to decelerated conduction, ischemia and hypertrophy are predominantly early signs of emerging HF, while only abnormalities related to ischemic disorders are signs of CHD.
