Effect of evidence-based therapy for secondary prevention of cardiovascular disease: Systematic review and meta-analysis

Low Attainment of Treatment Targets for Cardiovascular Risk Factors in Indonesian Adults With Established Coronary Artery Disease

RATIONALE

Established coronary artery disease (CAD) patients are at increased risk for recurrence of cardiovascular events and mortality due to non-attainment of recommended risk factor control targets.

OBJECTIVE

We aimed to evaluate the attainment of treatment targets for risk factor control among CAD patients as recommended in the Indonesian CVD prevention guidelines.

METHODS

Patients were consecutively recruited from the Makassar Cardiac Center at Wahidin Sudirohusodo Hospital, Indonesia. Targets for systolic blood pressure (SBP < 140 mmHg), low-density lipoprotein-cholesterol (LDL-C < 1.8 mmol/L), body mass index (BMI: 20-25 kg/m2), non-smoking status and antithrombotic use were assessed according to the national guideline. Attainment levels were evaluated in CAD population subgroups using logistic regression to identify patients who required more intensive monitoring.

RESULTS

A total of 395 CAD patients (median age: 57 years (IQR: 49-65), 63.8% men) were recruited between February and June 2021. We observed that 1.8% of the CAD patients met all risk factor treatment targets. LDL-C had the lowest attainment level (5.1%), followed by BMI (59.7%), SBP (62.8%), antithrombotic usage (76.7%) and non-smoking status (94.4%). Apart from lower attainment of SBP control in the 50+ years age group (aOR: 0.57, 95% CI: 0.35-0.94) and women (aOR: 0.53, 95% CI: 0.34-0.83), the attainment levels of other risk factors were consistently low across age, sex, marital status and educational subgroups.

CONCLUSION

These findings emphasize the urgent need for effective management and heightened awareness, particularly for controlling LDL-C in the CAD population. Action to address this issue is crucial for mitigating the CVD burden, particularly in low- and middle-income countries such as Indonesia.

Determinants of medication adherence in patients with acute coronary syndrome: a secondary analysis of a randomised clinical trial

BACKGROUND

Coronary heart disease (CHD) remains a leading cause of mortality and disability worldwide. Approximately half of the patients who have had a prior hospital admission for CHD will have a recurrent coronary event, with the majority of these occurring within 12 months. Despite well-established evidence-based therapies, medication non-adherence is highly prevalent and reasons for medication non-adherence are poorly understood. This study evaluates factors influencing adherence to secondary prevention medications in people with acute coronary syndrome (ACS).

METHODS

We performed a secondary analysis of TEXT messages to improve MEDication adherence and Secondary prevention after ACS (TEXTMEDS), a single-blind randomised clinical trial of 1424 patients with ACS from 18 hospitals across Australia. The primary outcome was self-reported medication adherence to each of up to five classes of guideline-recommended cardioprotective medications indicated for secondary prevention after ACS. Patients were followed up at 6-month and 12-month time points and were defined as adherent if at both time points, the proportion of indicated medications taken was >80% (>24/30 days in the preceding 1 month) for all five classes if not otherwise contraindicated. Logistic regression analysis and the Least Absolute Shrinkage and Selection Operator regularisation technique were used to assess the effect of sociodemographic and clinical factors on medication adherence.

RESULTS

The analyses included 1379 participants with complete adherence data (mean age 58.5±10.7 years; 1095 (79.4%) men). The following variables were associated with adherence to cardiovascular medications at both 6 and 12 months: greater number of total medications taken (OR: 1.33; 95% CI: 1.25 to 1.42) and attending a cardiac rehabilitation programme (1.47; 95% CI: 1.17 to 1.86). In contrast, female sex (0.67; 95% CI: 0.50 to 0.90) and physical disability (0.43; 95% CI: 0.23 to 0.77) were associated with lower likelihood of medication adherence.

CONCLUSIONS

Sociodemographic and clinical factors may influence medication adherence. Greater awareness, discussion and monitoring of these factors during patient follow-up may help improve medication adherence.

The impact of meteorological conditions on cardiovascular and cerebrovascular diseases in different microclimatic zones of low-latitude mountainous areas

Introduction

Epidemiological evidence suggests cerebrovascular disease (CVD) incidence is correlated to meteorological conditions. However, research on the primary meteorological factors influencing the incidence of CVD and their influence thresholds in low-latitude mountainous regions remains insufficient. We aimed to investigate the association between meteorological conditions and CVD occurrence in Guizhou province.

Methods

Utilizing daily incidence cases for CVD alongside concurrent meteorological data from four microclimate representative stations in Guizhou Province during 2021-2022, we firstly performed random forest and decision tree analysis to identify the significant meteorological factors influencing the incidence of CVD, and then we applied distributed lag non-linear model (DLNM) to assess the effect of meteorological factors on CVD incidence.

Results

Critical meteorological factors associated with CVD incidence include diurnal temperature range (DTR), temperature change between neighboring days (TCN), diurnal pressure range (DPR), pressure change between neighboring days (PCN), and minimum temperature. The risk of CVD incidence markedly increased with narrow DTR, positive TCN, and colder conditions. The thresholds of minimum temperature and TCN droped with the decrease of annual average temperature in microclimate zone. In the middle subtropical region of Jiangkou, the northern subtropical region of Xishui, and the warm temperate region of Shuicheng, there was a risk of CVD when the minimum temperature falled below 12.2°C, 10.7°C, and 6.7°C, respectively. When TCN exceeded the critical threshold (0.2°C in Shuicheng, 0.3°C in Xishui, and 0.4°C in Jiangkou and Ceheng), the risk of CVD incidence increased linearly. DPR and PCN displayed varied thresholds across different microclimate without consistent patterns. DPR in middle subtropical region of Jiangkou and warm temperate region of Shuicheng played a protective role, while the risk of the disease increased linearly when DPR was lower than 3.2 hPa and 2.7 hPa in south subtropical region of Ceheng and north subtropical region of Xishui, respectively. The short-term effects within 5 days with small DTR and narrow positive TCN were more obvious. The thresholds and lag times of other meteorological environmental factors remained indistinct in the four microclimate zones.

Discussion

Our findings delineated the common characteristics of the effect on the incidence of CVD of meteorological environments in various microclimate zones, and clarified the influence of minimum temperature and TCN exhibited spatial heterogeneity, Which may be assistance for meteorological risk forecasting in CVD prevention and control.

Single-pill combination for treatment of hypertension: Just a matter of practicality or is there a real clinical benefit?

Elevated blood pressure (BP) is the largest contributor to the incident cardiovascular disease worldwide. Despite explicit guideline recommendations for the diagnosis and management of hypertension, a large proportion of patients remain undiagnosed, untreated, or treated but uncontrolled. Inadequate BP control is associated with many complex factors including patient preference, physician's inertia, health systems disparities, and poor adherence to prescribed antihypertensive drug treatment. The primary driver for reduced cardiovascular morbidity and mortality is lowering of BP ''per se'' and not class effects of specific pharmacotherapies. The recent ESH guidelines recommend the use of four major classes of drugs including renin-angiotensin-aldosterone system (RAS) blockers (angiotensin receptor blockers (ARB) or angiotensin-converting enzyme inhibitors (ACEi)), calcium channel blockers (CCB), thiazide and thiazide-like diuretics, and betablockers. Initiation of treatment for hypertension with a two-drug regimen, preferably in a single pill combination (SPC), is recommended for most patients. Preferred combinations should comprise a RAS blocker (either an ACEi or an ARB) with a CCB or thiazide/thiazide-like diuretic. These strategies are supported by robust evidence that combination therapy produces greater BP reductions than monotherapy, reduces side effects of the individual components, improves therapeutic adherence and long-term persistence on treatment, and permits achievement of earlier BP control.

Prognostic impact of optimal lifestyle advice and medical therapy in patients with peripheral arterial disease

Background: Secondary prevention remains under-implemented in patients with peripheral arterial disease (PAD). In the present study, we sought to assess the extent, the predictors and the prognostic impact of optimal lifestyle advice (OLA) and optimal medical therapy (OMT) given at discharge to patients with PAD undergoing invasive peripheral procedures. Patients and methods: We included consecutive patients with PAD undergoing invasive peripheral procedures, between 2012 and 2013. Data were obtained from a mandatory fill-in clinical pathway. The primary outcome was all-cause mortality, verified using the National Mortality Registry. Results: A total of 2014 participants were included (mean age 70±11 years, 38.1% women). OLA was given to 279 (14%), OMT to 1186 (59%) participants. Male gender and absence of chronic limb-threatening ischaemia were significant predictors of OLA and OMT. During the median follow-up of 729 days (interquartile range 645) 392 (19.5%) participants died giving an overall mortality rate of 97/1000 patient years. On multivariate analysis both OLA and OMT emerged as independent predictors of survival (HR for all-cause mortality: 0.59; 95% CI: 0.42-0.82, p 0.005 and HR: 0.41; 95% CI: 0.22-0.76, p 0.002). Conclusions: OLA and OMT are associated with better long-term prognosis in patients with PAD, however they are still under-implemented, suggesting a considerable potential for improvement, especially in women.

Sex disparities in guideline-recommended therapies and outcomes after ST-elevation myocardial infarction in a contemporary nationwide cohort of patients over an eight-year period

BACKGROUND AND AIMS

Acute myocardial infarction (AMI) is the leading cause of death worldwide. Outcome has improved during the last decades due to secondary prevention and widespread coronary interventions, but recent studies still show sex differences and insufficient drug adherence. We aimed to determine differences in the treatment strategies and outcomes between women and men with ST-elevation myocardial infarction (STEMI) in Germany.

METHODS

From the Federal Association of the Local Health Insurance Funds (Allgemeine Ortskrankenkasse), 175,187 patients were identified who were hospitalized due to STEMI in Germany between January 1, 2010 and December 31, 2017.

RESULTS

Compared to men, women were older (median 76 vs. 64 years) and had more often diabetes, hypertension, chronic heart failure, and chronic kidney disease (all p <0.001). Women suffered from higher rates of in-hospital complications such as bleeding (9.3 vs. 6.6%), longer hospitalizations (12.2 vs. 11.7 days) and were less likely to undergo percutaneous coronary intervention (75.5 vs. 85.2%). After adjustment for patient's risk profile, female sex was associated with decreased overall survival (HR 1.02, 95% confidence interval (CI) 1.00-1.04; p=0.036). Notably, more men received all four guideline-recommended drugs after STEMI (women 65.7% vs. men 69.8% after 90 days; p <0.001). With increasing number of prescribed drugs, patients benefit even more. This concerned both sexes, but was more pronounced in men (with 4 prescribed drugs: women HR 0.52, 95%CI 0.50-0.55; men HR 0.48, 95% CI 0.47-0.50, pint = 0.014).

CONCLUSIONS

In a contemporary nationwide analysis, women with STEMI were older, had more comorbidities, underwent revascularization less often and had an increased risk for major complications as well as overall survival. Guideline-recommended drug therapy was applied less frequently in women although associated with an improved overall-survival.

The Prevalence and Impact of Evidence-Based Medications on Cardiovascular and Cerebrovascular Outcomes in Patients with Acute Coronary Syndrome Post-Revascularization in Oman

OBJECTIVES

International cardiovascular guidelines recommend prescribing a combination of five evidence-based medications (EBM) for acute coronary syndrome (ACS) patients post-revascularization. This study aims to assess the prevalence and impact of prescribing the full (five medications) versus partial (four medications or fewer) EBM combination on major adverse cardiovascular and cerebrovascular events (MACCE) in patients with ACS post-revascularization.

METHODS

Data from patients with ACS who had revascularization between January 2016 and September 2021 were collected retrospectively. Patients were then followed up until March 2022 for MACCE.

RESULTS

The full EBM combination was prescribed to 70% of the patients. However, after taking into account the presence of contraindications and clinical factors, the actual adherence to the guidelines was 95%. Patients who received the full EBM combination were younger (58 versus 62 years; p = 0.0 and 3) and had lower rates of chronic kidney disease (11% versus 41%; p < 0.001) and heart failure (9% versus 20%; p = 0.012) when compared to patients who received the partial EBM. Compared to the partial EBM group, the full EBM group was associated with lower MACCE rates (54% versus 37%, p = 0.012). After employing the propensity score technique utilizing the 1:1 nearest neighbor matching method without replacement, the univariate findings were further re-affirmed with those on full EBMs (compared to those on partial EBMs) associated with a significant reduction in the MACCE rate (average treatment effect of -25%; 95% confidence interval: -10--40%; p = 0.001).

CONCLUSIONS

The full EBM utilization was significantly high in our setting and in line with international guidelines. The full EBM combination was predominantly prescribed in younger and less comorbid patients and was associated with lower MACCE rates. The findings were further reaffirmed by the propensity score matching method.

Generating Practice-Based Evidence in the Use of Guideline-Recommended Combination Therapy for Secondary Prevention of Acute Myocardial Infarction

Background: Clinical guidelines recommend beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers, and statins for the secondary prevention of acute myocardial infarction (AMI). It is not clear whether variation in real-world practice reflects poor quality-of-care or a balance of outcome tradeoffs across patients. Methods: The study cohort included Medicare fee-for-service beneficiaries hospitalized 2007-2008 for AMI. Treatment within 30-days post-discharge was grouped into one of eight possible combinations for the three drug classes. Outcomes included one-year overall survival, one-year cardiovascular-event-free survival, and 90-day adverse events. Treatment effects were estimated using an Instrumental Variables (IV) approach with instruments based on measures of local-area practice style. Pre-specified data elements were abstracted from hospital medical records for a stratified, random sample to create "unmeasured confounders" (per claims data) and assess model assumptions. Results: Each drug combination was observed in the final sample (N = 124,695), with 35.7% having all three, and 13.5% having none. Higher rates of guideline-recommended treatment were associated with both better survival and more adverse events. Unmeasured confounders were not associated with instrumental variable values. Conclusions: The results from this study suggest that providers consider both treatment benefits and harms in patients with AMIs. The investigation of estimator assumptions support the validity of the estimates.

Age-Related Variation in the Provision of Primary Care Services and Medication Prescriptions for Patients with Cardiovascular Disease

As population aging progresses, demands of patients with cardiovascular diseases (CVD) on the primary care services is inevitably increased. However, the utilisation of primary care services across varying age groups is unknown. The study aims to explore age-related variations in provision of chronic disease management plans, mental health care, guideline-indicated cardiovascular medications and influenza vaccination among patients with CVD over differing ages presenting to primary care. Data for patients with CVD were extracted from 50 Australian general practices. Logistic regression, accounting for covariates and clustering effects by practices, was used for statistical analysis. Of the 14,602 patients with CVD (mean age, 72.5 years), patients aged 65-74, 75-84 and ≥85 years were significantly more likely to have a GP management plan prepared (adjusted odds ratio (aOR): 1.6, 1.88 and 1.55, respectively, p < 0.05), have a formal team care arrangement (aOR: 1.49, 1.8, 1.65, respectively, p < 0.05) and have a review of either (aOR: 1.63, 2.09, 1.93, respectively, p < 0.05) than those < 65 years. Patients aged ≥ 65 years were more likely to be prescribed blood-pressure-lowering medications and to be vaccinated for influenza. However, the adjusted odds of being prescribed lipid-lowering and antiplatelet medications and receiving mental health care were significantly lowest among patients ≥ 85 years. There are age-related variations in provision of primary care services and pharmacological therapy. GPs are targeting care plans to older people who are more likely to have long-term conditions and complex needs.

Treatment patterns and use of healthcare resources of patients with atherosclerotic cardiovascular disease and hypercholesterolemia and patients with familial hypercholesterolemia in Spain: Protocol of the Reality study

Background

Atherosclerotic cardiovascular diseases (ASCVD) and dyslipidemia are associated to a higher risk of cardiovascular events, mortality, use of healthcare resources and costs. In Spain, the evidence about the administration of lipid-lowering treatments in clinical practice, and their clinical effectiveness in patients with ASCVD and hypercholesterolemia and patients with FH is scarce. Therefore, a multidisciplinary working group of cardiologists, family physicians, internal medicine specialists and neurologists was gathered for the Reality study. The aim of this study is to describe the demographic and clinical characteristics, comorbidities, and concomitant medication of patients with ASCVD and hypercholesterolemia and of patients with familial hypercholesterolemia (FH). The use of healthcare resources and costs associated to the management of these diseases after their diagnosis were also considered.

Methods

This is an observational and retrospective study, based on the BIG-PAC® database, which includes the electronic medical registries (EMRs) of 1.8 million people from 7 Autonomous Communities in Spain (including public primary care centers and hospitals). The study includes patients who had a new or recurrent episode of ASCVD during the recruitment period (from 01/01/2017 to 31/12/2018). The index date will be defined as the date of the ASCVD event, and the follow-up period will be 24 months. According to their first diagnosis in the database, patients will be classified as ASCVD (5 groups: stable/unstable angina, acute myocardial infarction, ischemic stroke, transient ischemic attack, and peripheral arterial disease) or FH.

Discussion

This study aims to analyze the treatment patterns and use of healthcare resources of ASCVD and FH in Spain. The prevalence of these disorders will also be estimated. Due to the high morbidity and mortality associated with these diseases, it is expected that our study will provide useful information for healthcare systems and decision makers to improve the management of these disabling diseases.

Factors related to under-treatment of secondary cardiovascular risk, including primary healthcare: Australian National Health Survey linked data analysis

OBJECTIVE

To inform national evidence gaps on cardiovascular disease (CVD) preventive medication use and factors relating to under-treatment - including primary healthcare engagement - among CVD survivors in Australia.

METHODS

Data from 884 participants with self-reported CVD from the 2014-15 National Health Survey were linked to primary care and pharmaceutical dispensing data for 2016 through the Multi-Agency Data Integration Project. Logistic regression quantified the relation of combined blood pressure- and lipid-lowering medication use to participant characteristics.

RESULTS

Overall, 94.8% had visited a general practitioner (GP) and 40.0% were on both blood pressure- and lipid-lowering medications. Medication use was least likely in: women versus men (OR=0.49[95%CI:0.37-0.65]), younger participants (e.g. 45-64y versus 65-85y: OR=0.58[0.42-0.79])and current versus never-smokers (OR=0.73[0.44-1.20]). Treatment was more likely in those with ≥9 versus ≤4 conditions (OR=2.15[1.39-3.31]), with ≥11 versus 0-2 GP visits/year (OR=2.62[1.53-4.48]) and with individual CVD risk factors (e.g. high blood pressure OR=3.13 [2.34-4.19]) versus without); the latter even accounting for GP service-use frequency.

CONCLUSIONS

Younger people, smokers, those with infrequent GP visits or without CVD risk factors were the least likely to be on medication.

IMPLICATIONS FOR PUBLIC HEALTH

Substantial under-treatment, even among those using GP services, indicates opportunities to prevent further CVD events in primary care.

The Era of Polypills in the Management of Cardiovascular Diseases: Are We There Yet?

Cardiovascular Diseases (CVD) are the leading cause of mortality globally. Wald and Law proposed the idea of a 'polypill'; a fixed dose combination therapy (FDC) in the form of a single pill to curb the CVD epidemic. Such a drug would include the combination of a broad spectrum of drugs including cholesterol lowering drugs, antihypertensive drugs, anti-platelet drugs, anti-coagulation drugs, anti-arrhythmic drugs, which are frequently integrated to combat specific CVDs. This 'polypill' holds the potential to pose several advantages like increased compliance, improved quality of life, risk factor control, psychological relief, and cost effectiveness along with minimal side effects. Several trials (like TIPS, UMPIRE, PolyIran etc.) have tested different treatment strategies to test the hypothesis of Wald and Law. Unlike the past physicians are now highly aware of this new strategy.The future of polypill in the management of CVD lies in a strategy where polypills are treated supplementary to the already existing preventive care, which includes lifestyle modifications and efforts to reduce tobacco use.

The need for long-term personalized management of frail CVD patients by rehabilitation and telemonitoring: a framework

Due to advances in cardiovascular medicine and preventive cardiology, patients benefit from a better prognosis, even in case of significant disease burden such as acute and chronic coronary syndromes, advanced valvular heart disease and chronic heart failure. These advances have allowed CVD patients to increase their life expectancy, but on the other hand also experience aging-related syndromes such as frailty. Despite being underrecognized, frailty is a critical, common, and co-existent condition among older CVD patients, leading to exercise intolerance and compromised adherence to cardiovascular rehabilitation. Moreover, frail patients need a different approach for CR and are at very high risk for adverse events, but yet are underrepresented in conventional CR. Fortunately, recent advances have been made in technology, allowing remote monitoring, coaching and supervision of CVD patients in secondary prevention programs with promising benefits. Similarly, we hypothesized that such programs should also be implemented to treat frailty in CVD patients. However, considering frail patients' particular needs and challenges, telerehabilitation interventions should thus be appropriately adapted. Our purpose is to provide, for the first time and based on expert opinions, a framework of how such a cardiac telerehabilitation program could be developed and implemented to manage a prevention and rehabilitation program for CVD patients with frailty.

A phenomenological analysis of the experience of taking medication to prevent a further heart attack

Following an acute myocardial infarction, patients are prescribed a regime of cardio-protective medication to prevent recurrent cardiovascular events and mortality. Adherence to medication is poor in this patient group, and not fully understood. Current interventions have made limited improvements but are based upon presumed principles. To describe the phenomenon of medicine-taking for an individual taking medication for secondary prevention for an AMI, Interpretative Phenomenological Analysis was used to analyse transcripts of semi-structured interviews with participants. Themes were generated for each participant, then summarized across participants. Five key themes were produced; the participants needed to compare themselves to others, showed that knowledge of their medicines was important to them, discussed how the future was an unknown entity for them, had assimilated their medicines into their lives, and expressed how an upset to their routine reduced their ability to take medication. Participants described complex factors and personal adaptations to taking their medication. This suggests that a patient-centred approach is appropriate for adherence work, and these themes could inform clinical practice to better support patients in their medicine adherence.

Gender disparity in the prescription of secondary prevention medications in a Malaysian primary care clinic

INTRODUCTION

Cardiovascular disease is the leading cause of death worldwide. Despite the proven benefit of secondary prevention medications (SPMs), their utilisation remains suboptimal in many countries. This study aimed to assess the use of SPMs in a Malaysian primary care clinic and factors associated with it.

METHODS

A retrospective review of electronic medical records was conducted to assess the prescription of SPMs among patients with coronary artery disease who attended the clinic between 1st January 2018 and 31st December 2018. Prescriptions of SPMs were documented in numbers and percentages. Multiple logistic regressions were used to analyse factors associated with the prescription of SPMs.

RESULTS

Of the 662 patients included in the study, 99.1% were prescribed statins, 97% antiplatelets, 81.7% angiotensin-converting enzyme (ACE)-inhibitors or angiotensin II receptor blockers (ARBs), and 78.7% beta-blockers. Male patients were more likely to be prescribed statins (OR = 8.584, 95% CI: 1.431 - 51.510) and antiplatelets (OR = 6.818, 95% CI: 2.294 - 20.257). Another significant factor for antiplatelets prescription was having diabetes (OR = 3.318, 95% CI: 1.148 - 9.590). Having hypertension was associated with ACE-inhibitors or ARBs prescription (OR = 4.008, 95% CI: 2.522 - 6.370).

CONCLUSION

Although the majority of patients received SPMs, there were significant disparities for some SPMs prescriptions among female patients. As these medications are widely available in the Malaysian primary care setting, steps should be taken to ensure that these medications are prescribed equally for all eligible patients.

The value of the polypill in cardiovascular disease: an Italian multidisciplinary Delphi panel consensus

The purpose of this work was to reach the consensus of a multidisciplinary and multistakeholder Italian panel on the value of polypill in cardiovascular disease, with respect to the clinical, technological, economic and organizational dimension. A three-step modified Delphi method was used to establish consensus. Eleven experts in the area of cardiology, pharmaceutical technology, general practice, hospital pharmacy, pharmacology, and health economics participated in the expert panel. To identify existing evidence concerning the value of polypill in the prevention of patients with cardiovascular disease, a systematic literature review was carried out according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement guidelines. In the first round, 22 statements were distributed to the panel. Panel members were asked to mark 'agree' or 'disagree' for each statement and provide any comments. The same voting method was again used for the second round. In the first round nine statements met consensus. In the second round, 10 statements reached consensus. Overall, consensus was reached for 19 statements representing five value polypill domains: clinical, technological, economic and organizational. During a final web meeting with all panel members consensus document open points were discussed. Panel members agreed to recognize polypill as effective in reducing cardiovascular events, blood pressure and lipids, cardiovascular risk and the weight of therapy, in therapeutic adherence improvement, in the absence of differences in bioavailability between drugs administered in fixed or free combinations and the better cost-effectiveness profile compared with standard care. This document represents a knowledge framework to inform decision makers of the value of polypill in cardiovascular prevention.

Fragility fracture identifies patients at imminent risk for subsequent fracture: real-world retrospective database study in Ontario, Canada

BACKGROUND

The secondary fracture prevention gap in the osteoporosis field has been previously described as a 'crisis'. Closing this gap is increasingly important in the context of accumulating evidence showing that an incident fragility fracture is associated with an increased risk of subsequent fracture within 1-2 years, known as imminent fracture risk. The objective of this study was to use health services data to characterize the time between index fragility fractures occurring at different osteoporotic sites and subsequent fractures.

METHODS

This retrospective observational study used de-identified health services data from the publicly funded healthcare system in Ontario, the largest province of Canada. Patients aged > 65 with an index fragility fracture occurring between 2011 and 2015 were identified from the ICES Data Repository using International Classification of Diseases (ICD)-10 codes. We examined median time to subsequent fragility fractures for osteoporotic fracture sites until the end of follow-up (2017). BMD assessment and use of osteoporosis therapies following index fracture were also characterized.

RESULTS

Among 115,776 patients with an index fragility fracture, 17.8% incurred a second fragility fracture. Median time between index and second fracture occurring at any site was 555 days (interquartile range: 236-955). For each index fracture site examined, median time from index to second fracture was < 2 years. The proportion of patients with BMD assessment was 10.3% ≤1 year prior to and 16.4% ≤1 year post index fracture. The proportion of patients receiving osteoporosis therapy was 29.8% ≤1 year prior, 34.6% ≤1 year post, and 25.9% > 3 years post index fracture.

CONCLUSIONS

This cohort of Canadian patients aged > 65 years who experienced a fragility fracture at any site are at imminent risk of experiencing subsequent fracture within the next 2 years and should be proactively assessed and treated.

Use of Cardiovascular Drugs for Primary and Secondary Prevention of Cardiovascular Disease Among Rural-Dwelling Older Chinese Adults

Cardiovascular risk factors and related disorders are common among older adults, and use of various classes of cardiovascular (CV) drugs could reduce the risk of cardiovascular disease (CVD). However, data are sparse with regard to the use of CV drugs among rural-dwelling older adults in China. Therefore, this population-based study aimed to describe use of CV drugs among older adults living in the rural communities in China, while taking into account the use of CV drugs for primary and secondary prevention of CVDs. This study included 5,246 participants (age ≥65 years; 57.17% women; 40.68% illiteracy) in the baseline examination of the MIND-China study. In March-September 2018, data on health-related factors, CVDs (ischemic heart disease, atrial fibrillation, heart failure, and stroke), and CV drug use were collected via face-to-face survey, clinical examination, and laboratory tests. We classified CV drugs according to the Anatomical Therapeutic Chemical classification system for western medications and specific cardiovascular effects for the products of traditional Chinese medicine (TCM). We conducted descriptive analysis. The overall prevalence of major cardiovascular risk factors ranged from 14.30% in diabetes and 23.81% in dyslipidemia to 66.70% in hypertension, and CVDs affected 35.07% of all participants (36.28% in women vs. 33.47% in men, p = 0.035). In the total sample, calcium channel blockers (C08) were most commonly used (10.39%), followed by TCM products (7.64%), hypoglycemic agents (A10, 4.73%), renin-angiotensin system (RAS)-acting agents (C09, 4.61%), and lipid-lowering agents (C10, 4.17%). The proportions of CV drugs for primary prevention (i.e., use of CV drugs among people without CVD) were 3.14% for antithrombotic agents (mainly aspirin), 1.38% for lipid-lowering agents, and 3.11% for RAS-acting agents; the corresponding figures for secondary prevention (i.e., use of CV drugs among people with CVD) were 13.97%, 9.35%, and 7.39%. In conclusion, despite highly prevalent cardiovascular risk factors and CVDs, a fairly low proportion of the rural-dwelling older adults take CV medications for primary and secondary prevention. Notably, TCM products are among the most commonly used CV drugs. These results call for additional efforts to promote implementation of the evidence-based recommendations for prevention of CVDs in the primary care settings.

The value of WeChat application in chronic diseases management in China

The prevalence of chronic diseases in China has increased rapidly in recent decades. Although the management rate of chronic diseases has improved, there is still no unified and effective management measure for chronic diseases at present. This highlights the importance of effectively managing chronic diseases. With the development of e-health, the ways of getting medical consultation have changed. WeChat is an extremely popular social application in China. It is easy to operate and can offer multiple functions. Many researches have reported the effectiveness of WeChat in chronic diseases management. Based on the status of WeChat application in chronic diseases management and the characteristics of WeChat technology, we firstly focused on the WeChat application on the management of chronic diseases such as hypertension, diabetes, coronary heart disease and cancer. Then we discussed the value of WeChat in chronic diseases management and analyzed the potential reasons. Lastly, we discussed the limitations of present researches.

A practical approach to switch from a multiple pill therapeutic strategy to a polypill-based strategy for cardiovascular prevention in patients with hypertension

: Pharmacological treatment recommended by guidelines for very high-risk patients with established cardiovascular disease (CVD) includes lipid-lowering drugs, antihypertensive agents and antiplatelet therapy. Depending on the associated comorbidities, this baseline regimen has to be complemented with other drugs. Therefore, the number of pills to be taken is usually high and adherence to these multiple pill therapeutic regimens and long-term persistence on treatment is low, being the main factor for insufficient control of cardiovascular risk factors. The CNIC (Centro Nacional de Investigaciones Cardiovasculares, Ministerio de Ciencia e Innovación, España) polypill is the only polypill containing low-dose aspirin approved by the EMA and marketed in Europe, and has demonstrated to improve adherence. For this reason, guidelines recommend its use for secondary prevention of CVD, and also for primary prevention of cardiovascular events in patients with multiple cardiovascular risk factors and advanced atherosclerotic process at high risk of thrombosis and low risk of bleeding. This article pretends to simplify the steps that clinicians may follow to switch from any baseline regimen to the polypill with the use of several algorithms and tables showing the equivalent effective daily doses of different angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers and statins to facilitate switching, as well as the steps to be followed depending of the initial levels of BP and LDL-cholesterol values to achieve BP and lipid control with the association to the polypill of other BP-lowering or lipid-lowering drugs whenever needed.

Initial cardiovascular treatment patterns during the first 90 days following an incident cardiovascular event

AIMS

The aim of this study was to investigate the initial cardiovascular prescription patterns in patients after their first cardiovascular events, and to identify factors associated with cardiovascular polypharmacy.

METHODS

This was a cross-sectional study including patients aged ≥ 45 years with the first record of coronary heart disease (CHD) or stroke between 2007 and 2016 using The Health Improvement Network database. This study investigated the patterns of cardiovascular drugs prescribed during the first 90 days after the first cardiovascular events. Logistic regression was used to examine the association between patients' baseline characteristics and cardiovascular polypharmacy (≥5 cardiovascular drugs).

RESULTS

A total of 121,600 (59,843 CHD and 61,757 stroke) patients were included in the study. The mean age was 69.5 ± 11.9 years. The proportion of patients who were prescribed 0-1, 2-3, 4-5 drugs and ≥6 drugs were 11.0%, 29.8%, 38.6% and 20.5%, respectively. Factors associated with cardiovascular polypharmacy were sex (female: OR 0.74, 95% CI 0.72-0.76 vs male), age (75-84 years old: OR 0.50, 0.47-0.53 vs 45-54 years old), smoking status (current smoking: OR 1.29, 1.15-1.24 vs never), body mass index (obesity: OR 1.38, 1.34-1.43 vs normal), deprivation status (most deprived: OR 1.09, 1.04-1.14 vs least deprived) and Charlson comorbidity index (index ≥5: OR 1.25, 1.16-1.35 vs index 0).

CONCLUSION

Multiple cardiovascular drugs treatment was common in patients with CVD in the UK. High-risk factors of CVD were also associated with cardiovascular polypharmacy. Further studies are warranted to assess the impact of cardiovascular polypharmacy and its interaction on CVD recurrence and mortality.

Sex Differences in Primary and Secondary Prevention of Cardiovascular Disease in China

BACKGROUND

Despite improvements in diagnostic and therapeutic interventions to combat cardiovascular disease (CVD) in recent decades, there are significant ongoing access gaps and sex disparities in prevention that have not been adequately quantified in China.

METHODS

A representative, cross-sectional, community-based survey of adults (aged ≥45 years) was conducted in 7 geographic regions of China between 2014 and 2016. Logistic regression models were used to determine sex differences in primary and secondary CVD prevention, and any interaction by age, education level, and area of residence. Data are presented as adjusted odds ratios (ORs) and 95% CIs.

RESULTS

Of 47 841 participants (61.3% women), 5454 (57.2% women) had established CVD and 9532 (70.5% women) had a high estimated 10-year CVD risk (≥10%). Only 48.5% and 48.6% of women and 39.3% and 59.8% of men were on any kind of blood pressure (BP)-lowering medication, lipid-lowering medication, or antiplatelet therapy for primary and secondary prevention, respectively. Women with established CVD were significantly less likely than men to receive BP-lowering medications (OR, 0.79 [95% CI, 0.65-0.95]), lipid-lowering medications (OR, 0.69 [95% CI, 0.56-0.84]), antiplatelets (OR, 0.53 [95% CI, 0.45-0.62]), or any CVD prevention medication (OR, 0.62 [95% CI, 0.52-0.73]). Women with established CVD, however, had better BP control (OR, 1.31 [95% CI, 1.14-1.50]) but less well-controlled low-density lipoprotein cholesterol (OR, 0.66 [95% CI, 0.57-0.76]), and were less likely to smoke (OR, 13.89 [95% CI, 11.24-17.15]) and achieve physical activity targets (OR, 1.92 [95% CI, 1.61-2.29]). Conversely, women with high CVD risk were less likely than men to have their BP, low-density lipoprotein cholesterol, and bodyweight controlled (OR, 0.46 [95% CI, 0.38-0.55]; OR, 0.60 [95% CI, 0.52-0.69]; OR, 0.55 [95% CI, 0.48-0.63], respectively), despite a higher use of BP-lowering medications (OR, 1.21 [95% CI, 1.01-1.45]). Younger patients (<65 years) with established CVD were less likely to be taking CVD preventive medications, but there were no sex differences by area of residence or education level.

CONCLUSIONS

Large and variable gaps in primary and secondary CVD prevention exist in China, particularly for women. Effective CVD prevention requires an improved overall nationwide strategy and a special emphasis on women with established CVD, who have the greatest disparity and the most to benefit.

Rising Trends in Medication Non-compliance and Associated Worsening Cardiovascular and Cerebrovascular Outcomes Among Hospitalized Adults Across the United States

Introduction

Small-scale studies have described concerning rates of non-compliance/nonadherence towards groups of medications for primary and secondary prevention. Trends in cardiovascular and cerebrovascular events (CCE) among hospitalized patients with a non-compliant behavior towards medication, on the whole, remains unexplored on a large scale.

Methods

Using the National Inpatient Sample databases (2007-2014), we sought to assess the prevalence and trends in all-cause mortality and CCE in adult patients hospitalized with medication non-compliance. We compared baseline characteristics and comorbidities in the non-compliant patients with and without concomitant in-hospital CCE.

Results

We identified 7,453,831 adult hospitalizations with medication non-compliance from 2007 to 2014, of which 867,997 (11.6%) patients demonstrated in-hospital CCE. Non-compliant patients with CCE consisted of a higher number of older, white, male patients having greater comorbid risk factors. Non-compliant patients with CCE had higher all-cause in-hospital mortality (3% vs. 0.7%), frequent transfers [4.4% vs. 1.8% transfers to short-term hospitals, and 17.6% vs. 11.6% other transfers (skilled nursing or intermediate care facilities)], lower routine discharges (59.4% vs. 71.1%), and higher mean hospital charges ($52,740 vs. $30,748) compared to non-compliant patients without CCE. Remarkably, this study demonstrates the rising trend in medication non-compliance across all age, sex, and race groups, and related in-hospital mortality, CCE, transfers to other facilities, and the health care cost from 2007 to 2014.

Conclusions

We observed rising trends in the prevalence of medication non-compliance and subsequent in-hospital mortality in hospitalizations among adults from 2007 to 2014. Non-compliant patients with inpatient CCE demonstrated rising trends in all-cause mortality, complications, health care utilization, and cost from 2007 to 2014.
