Best practice for prevention and treatment of cardiovascular disease through an equity lens: a review

Contextual factors in systematic reviews: understanding public health interventions in low socioeconomic status and disadvantaged populations

BACKGROUND

Evaluations of public health interventions require an understanding of the contextual factors that shape their effectiveness. Context (including socioeconomic, cultural, and environmental factors) plays a critical role in establishing how interventions achieve impact, why outcomes can vary and whether the interventions of interest can be translated from one context to another. This overview explores the extent to which systematic reviews of public health interventions for low-income or low socioeconomic status (SES) populations report contextual factors influencing outcomes.

METHODS

Systematic reviews were identified through a scoping review and updated searches in March 2023. Reviews focused on interventions targeting smoking, unhealthy diet, physical inactivity, and harmful alcohol use in disadvantaged groups. Reviews were screened for eligibility, and data were extracted on contextual factors related to intervention implementation and effectiveness. Data were synthesised using a framework approach, categorising findings by behaviour and level of intervention.

RESULTS

Applying a very broad definition of context, 29 of 86 identified reviews provided some degree of contextual data which varied across interventions but was largely restricted to intervention implementation and delivery factors. For example, environmental characteristics, such as crime and perceived personal safety, affected the use of physical activity infrastructure in disadvantaged areas. Food voucher schemes had mixed results, with social and economic factors affecting their use and effectiveness. However, most reviews lacked sufficient reporting on contextual data, limiting conclusions on the role of context in intervention outcomes.

CONCLUSIONS

Contextual factors are often underreported in systematic reviews of public health interventions targeting disadvantaged populations. Such underreporting is likely to be similar in other areas of public health. This limits policymakers' ability to adapt interventions to specific settings. Improved reporting and consideration of context in systematic reviews are needed to ensure that interventions are appropriately tailored to the needs of low-income and low SES groups.

Real world effectiveness of Hawthorn special extract WS 1442 in a retrospective cohort study from Germany

Hawthorn special extract WS 1442 has beneficial effects on the cardiovascular system. Experimental studies have shown an antiarrhythmic effect of the substance. In the present study, we investigated antiarrhythmic effects of WS 1442 compared with magnesium/potassium in a large collective of outpatients. Using the IQVIA Disease Analyzer (DA) database, we included 4550 patients with a prescription of WS 1442 and 4550 matched patients with Tromcardin prescriptions (all registered products under the trademark Tromcardin that are magnesium and potassium supplementing foods for special medical purposes) who were followed for 5 years after the index date. The incidence of various cardiac arrhythmias (atrial fibrillation and flutter (AFF), tachycardia, and other cardiac arrhythmias) was recorded. Cox regression models were used to evaluate the potential association between both drugs and arrhythmias. The cumulative incidence of atrial fibrillation and flutter was significantly lower among patients with a prescription of WS 1442 compared to patients with magnesium/potassium prescriptions (10.8% vs. 16.4%, p < 0.001). WS 1442 prescription was significantly associated with a lower incidence of atrial fibrillation and flutter compared to magnesium/potassium (HR 0.71; 95% CI 0.64-0.80; p < 0.001). The cumulative incidence of tachycardia was significantly lower in the WS 1442 group compared to the magnesium/potassium group (8.3% vs. 9.4%, p < 0.001), similarly, the cumulative incidence of other cardiac arrhythmias was significantly lower among patients with WS 1442 compared to patients with magnesium/potassium (10.2% vs. 14.8%, p < 0.001). This study showed that in a large collective of outpatients, intake of hawthorn special extract WS 1442 was associated with a significantly lower incidence of atrial fibrillation, tachycardia, and other cardiac arrhythmias compared to magnesium/potassium, indicating its potential in treating and preventing such conditions.

Out-of-pocket expenditure on community healthcare services at end-of-life among decedents from cardiovascular disease in six European countries and Israel

OBJECTIVES

Most people who develop chronic diseases, including cardiovascular disease (CVD), live in their homes in the community in their last year of life. Since cost-sharing is common in most countries, including those with universal health insurance, these people incur out of pocket expenditure (OOPE). The study aims to identify the prevalence and measure the size of OOPE among CVD decedents at end-of-life (EOL) explore differences among countries in OOPE, and examine whether the decedents' characteristics or their countries' health policy affects OOPE more.

METHODS

SHARE data among people aged 50 + from seven European countries (including Israel) who died from CVD are analyzed. Decedents' family members are interviewed to learn about OOPE on their relatives' account.

RESULTS

We identified 1,335 individuals who had died from CVD (average age 80.8 years, 54% men). More than half of CVD-decedent people spend OOPE on community services at EOL and their expenditure varies widely among countries. About one-third of people in France and Spain had OOPE, rising to around two-thirds in Israel and Italy and almost all in Greece. The average OOPE is 391.9 PPT, with wide variance across countries. Significant odds of OOPE exist in the country variable only, and significant differences exist in the amount of OOPE among countries and duration of illness preceding death.

CONCLUSIONS

Since improving CVD care efficiency and effectiveness are key aims, healthcare policymakers should broaden the investigation into expanding public funding for community services in order to mitigate OOPE, alleviate the economic burden on households, mitigate forgoing of community services due to price, and reduce rehospitalization.

Representations of clinical practice guidelines and health equity in healthcare literature: An integrative review

AIM

This paper reports an integrative review of international health literature that discusses health equity in relation to clinical practice guidelines (CPGs).

BACKGROUND

Healthcare professionals (HCPs), policy makers, and decision makers rely on sound empirical evidence to make fiscally responsible and appropriate decisions about the allocation of health resources and health service delivery. CPGs provide statements and recommendations that aim to standardize care with an implicit goal of achieving equity of care among diverse populations. Developers of CPGs must be careful not to exacerbate inequity when making recommendations. As such, it is important to determine how equity is discussed within the context of CPGs.

DESIGN

This integrative review was conducted according to integrative review methods as outlined by Whittemore and Knafl (2005), and Toronto and Remington (2020). These authors outlined a systematic process for the identification of relevant literature across health disciplines to examine the state of knowledge pertaining to a phenomenon such as health equity.

SEARCH METHODS

The computerized databases PubMed, CINAHL, Cochrane, Embase, Medline, and Web of Science were searched using a combination of keywords. Search parameters included international peer-reviewed published, full-text, English language articles, editorials, and reports over the last decade (January 2011 to February 2022). A reference search of included articles was conducted to identify any additional articles. Dissertations and theses were not included.

SEARCH OUTCOME

A total of 139 peer-reviewed English language articles were identified.

RESULTS

The findings of this review revealed five main ways in which health equity is in context of CPGs including if they target or exacerbate inequity among disadvantaged populations, equity and CPG development, implementation, and evaluation, and checklists and tools to assist developers and users of CPG to consider equity. Although critical appraisal tools exist to assist users of CPGs assess and to evaluate how well CPGs address issues of equity, the definition of equity and how CPG development panels should incorporate and articulate it remains unclear and haphazard. As such, recommendations intended to be implemented by HCPs to optimize health equity remains diverse and unclear.

CONCLUSION

The way equity is discussed within the reviewed health literature has implications for their uptake by and utility for HCPs. The ability of HCPs to implement CPGs may be hindered without an appreciation and integration of equity considerations across the various phases of CPG conceptualization, development, implementation, and evaluation, and their relevance and appropriateness to diverse geographic and socioeconomic contexts with variable access to health human resources and services. This situation could be improved if equity were more clearly articulated within all aspects of the CPG process.

CLINICAL RELEVANCE

Understanding how equity is discussed in the literature relative to CPGs has implications for their uptake by and utility for HCPs in their goal of providing equitable health care. Successful implementation of CPGs with consideration equity could be improved if equity were more clearly articulated within all aspects of the CPG process including conceptualization, development, implementation, and evaluation.

Education inequalities in cardiovascular and coronary heart disease in Italy and the role of behavioral and biological risk factors

BACKGROUND AND AIMS

Behavioral and biological risk factors (BBRF) explain part of the variability in socioeconomic differences in health. The present study aimed at evaluating education differences in incidence of cardiovascular disease (CVD) and coronary heart disease (CHD) in Italy and the role of BBRF.

METHODS AND RESULTS

All subjects aged 30-74 years (n = 132,686) who participated to the National Health Interview Surveys 2000 and 2005 were included and followed-up for ten years. Exposure to smoking, physical activity, overweight/obesity, diabetes and hypertension at baseline was considered. Education level was used as an indicator of socioeconomic status. The outcomes were incident cases of CVD and CHD. Hazard ratios by education level were estimated, adjusting for sociodemographic covariates and stratifying by sex and geographic area. The contribution of BBRF to education inequalities was estimated by counterfactual mediation analysis, in addition to the assessment of the risk attenuation by comparing the models including BBRF or not. 22,214 participants had a CVD event and 6173 a CHD event. After controlling for sociodemographic factors, the least educated men showed a 21% higher risk of CVD and a 17% higher risk of CHD compared to the most educated (41% and 61% among women). The mediating effect (natural indirect effect) of BBRF between extreme education levels was 52% for CVD and 84% for CHD among men (16% among women for CVD).

CONCLUSIONS

More effective strategies aiming at reducing socioeconomic disparities in CVD and CHD are needed, through programs targeting less educated people in combination with community-wide initiatives.

Development of a Community-Based e-Health Program for Older Adults With Chronic Diseases: Pilot Pre-Post Study

Background

Chronic diseases may impact older adults’ health outcomes, health care costs, and quality of life. Self-management is expected to encourage individuals to make autonomous decisions, adhere to treatment plans, deal with emotional and social consequences, and provide choices for healthy lifestyle. New eHealth solutions significantly increase the health literacy and empower patients in self-management of chronic conditions.

Objective

This study aims to develop a Community-Based e-Health Program (CeHP) for older adults with chronic diseases and conduct a pilot evaluation.

Methods

A pilot study with a 2-group pre- and posttest repeated measures design was adopted. Community-dwelling older adults with chronic diseases were recruited from senior activity centers in Singapore. A systematic 3-step process of developing CeHP was coupled with a smart-device application. The development of the CeHP intervention consists of theoretical framework, client-centric participatory action research process, content validity assessment, and pilot testing. Self-reported survey questionnaires and health outcomes were measured before and after the CeHP. The instruments used were the Self-care of Chronic Illness Inventory (SCCII), Healthy Aging Instrument (HAI), Short-Form Health Literacy Scale, 12 Items (HLS-SF 12), Patient Empowerment Scale (PES), and Social Support Questionnaire, 6 items. The following health outcomes were measured: Montreal Cognitive Assessment, Symbol Digit Modalities Test, total cholesterol (TC), high-density lipoproteins, low-density lipoproteins/very-low-density lipoproteins (LDL/VLDL), fasting glucose, glycated hemoglobin (HbA_1c), and BMI.

Results

The CeHP consists of health education, monitoring, and an advisory system for older adults to manage their chronic conditions. It is an 8-week intensive program, including face-to-face and eHealth (Care4Senior App) sessions. Care4Senior App covers health education topics focusing on the management of hypertension, hyperlipidemia, and diabetes, brain health, healthy diet, lifestyle modification, medication adherence, exercise, and mindfulness practice. Content validity assessment indicated that the content of the CeHP is valid, with a content validity index (CVI) ranging 0.86-1 and a scale-CVI of 1. Eight participants in the CeHP group and 4 in the control group completed both baseline and post intervention assessments. Participants in the CeHP group showed improvements in fasting glucose, HbA_1c, TC, LDL/VLDL, BMI, SCCII indices (Maintenance, Monitoring, and Management), HAI, and PES scores post intervention, although these changes were not significant. For the participants in the control group, the scores for SCCII (management and confidence) and HLS-SF 12 decreased post intervention.

Conclusions

The CeHP is feasible, and it engages and empowers community-dwelling older adults to manage their chronic conditions. The rigorous process of program development and pilot evaluation provided valid evidence to expand the CeHP to a larger-scale implementation to encourage self-management, reduce debilitating complications of poorly controlled chronic diseases, promote healthy longevity and social support, and reduce health care costs.

OUP accepted manuscript

The management of patients with stroke is often multidisciplinary, involving various specialties and healthcare professionals. Given the common shared risk factors for stroke and cardiovascular disease, input may also be required from the cardiovascular teams, as well as patient caregivers and next-of-kin. Ultimately, the patient is central to all this, requiring a coordinated and uniform approach to the priorities of post-stroke management, which can be consistently implemented by different multidisciplinary healthcare professionals, as part of the patient ‘journey’ or ‘patient pathway,’ supported by appropriate education and tele-medicine approaches. All these aspects would ultimately aid delivery of care and improve patient (and caregiver) engagement and empowerment. Given the need to address the multidisciplinary approach to holistic or integrated care of patients with heart disease and stroke, the European Society of Cardiology Council on Stroke convened a Task Force, with the remit to propose a consensus on Integrated care management for optimizing the management of stroke and associated heart disease. The present position paper summarizes the available evidence and proposes consensus statements that may help to define evidence gaps and simple practical approaches to assist in everyday clinical practice. A post-stroke ABC pathway is proposed, as a more holistic approach to integrated stroke care, would include three pillars of management:

A: Appropriate Antithrombotic therapy.

B: Better functional and psychological status.

C: Cardiovascular risk factors and Comorbidity optimization (including lifestyle changes).

What impact do chronic disease self-management support interventions have on health inequity gaps related to socioeconomic status: a systematic review

Background

The social gradient in chronic disease (CD) is well-documented, and the ability to effectively self-manage is crucial to reducing morbidity and mortality from CD. This systematic review aimed to assess the moderating effect of socioeconomic status on self-management support (SMS) interventions in relation to participation, retention and post-intervention outcomes.

Methods

Six databases were searched for studies of any design published until December 2018. Eligible studies reported on outcomes from SMS interventions for adults with chronic disease, where socioeconomic status was recorded and a between-groups comparison on SES was made. Possible outcomes were participation rates, retention rates and clinical or behavioural post-intervention results.

Results

Nineteen studies were retrieved, including five studies on participation, five on attrition and nine studies reporting on outcomes following SMS intervention. All participation studies reported reduced engagement in low SES cohorts. Studies assessing retention and post-intervention outcomes had variable results, related to the diversity of interventions. A reduction in health disparity was seen in longer interventions that were individually tailored. Most studies did not provide a theoretical justification for the intervention being investigated, although four studies referred to Bandura’s concept of self-efficacy.

Conclusions

The limited research suggests that socioeconomic status does moderate the efficacy of SMS interventions, such that without careful tailoring and direct targeting of barriers to self-management, SMS may exacerbate the social gradient in chronic disease outcomes. Screening for patient disadvantage or workload, rather than simply recording SES, may increase the chances of tailored interventions being directed to those most likely to benefit from them. Future interventions for low SES populations should consider focussing more on treatment burden and patient capacity.

2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease: Executive Summary: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines

A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines

Endorsed by the American Association of Cardiovascular and Pulmonary Rehabilitation, the American Geriatrics Society, the American Society of Preventive Cardiology, and the Preventive Cardiovascular Nurses Association

2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease: Executive Summary: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines

1. The most important way to prevent atherosclerotic vascular disease, heart failure, and atrial fibrillation is to promote a healthy lifestyle throughout life.

2. A team-based care approach is an effective strategy for the prevention of cardiovascular disease. Clinicians should evaluate the social determinants of health that affect individuals to inform treatment decisions.

3. Adults who are 40 to 75 years of age and are being evaluated for cardiovascular disease prevention should undergo 10-year atherosclerotic cardiovascular disease (ASCVD) risk estimation and have a clinician–patient risk discussion before starting on pharmacological therapy, such as antihypertensive therapy, a statin, or aspirin. The presence or absence of additional risk-enhancing factors can help guide decisions about preventive interventions in select individuals, as can coronary artery calcium scanning.

4. All adults should consume a healthy diet that emphasizes the intake of vegetables, fruits, nuts, whole grains, lean vegetable or animal protein, and fish and minimizes the intake of trans fats, processed meats, refined carbohydrates, and sweetened beverages. For adults with overweight and obesity, counseling and caloric restriction are recommended for achieving and maintaining weight loss.

5. Adults should engage in at least 150 minutes per week of accumulated moderate-intensity physical activity or 75 minutes per week of vigorous-intensity physical activity.

6. For adults with type 2 diabetes mellitus, lifestyle changes, such as improving dietary habits and achieving exercise recommendations are crucial. If medication is indicated, metformin is first-line therapy, followed by consideration of a sodium-glucose cotransporter 2 inhibitor or a glucagon-like peptide-1 receptor agonist.

7. All adults should be assessed at every healthcare visit for tobacco use, and those who use tobacco should be assisted and strongly advised to quit.

8. Aspirin should be used infrequently in the routine primary prevention of ASCVD because of lack of net benefit.

9. Statin therapy is first-line treatment for primary prevention of ASCVD in patients with elevated low-density lipoprotein cholesterol levels (≥190 mg/dL), those with diabetes mellitus, who are 40 to 75 years of age, and those determined to be at sufficient ASCVD risk after a clinician–patient risk discussion.

10. Nonpharmacological interventions are recommended for all adults with elevated blood pressure or hypertension. For those requiring pharmacological therapy, the target blood pressure should generally be <130/80 mm Hg.

The Equity Impact of Proactive Outreach to Smokers: Analysis of a Randomized Trial

INTRODUCTION

Population-based smoking-cessation services tend to preferentially benefit high-SES smokers, potentially exacerbating disparities. Interventions that include proactive outreach, telephone counseling, and free or low-cost cessation medications may be more likely to help low-SES smokers quit. This analysis evaluated the role of SES in smokers' response to a population-based proactive smoking-cessation intervention.

METHODS

This study, conducted in 2016 and 2017, was a secondary analysis of the Veterans Victory Over Tobacco Study, a multicenter pragmatic RCT of a proactive smoking-cessation intervention conducted from 2009 to 2011. Logistic regression modeling was used to test the effect of income or education level on 6-month prolonged abstinence at 1-year follow-up.

RESULTS

Of the 5,123 eligible, randomized participants, 2,565 (50%) reported their education level and 2,430 (47%) reported their income level. The interactions between education (p=0.07) or income (p=0.74) X treatment arm were not statistically significant at the 0.05 level. The largest effect sizes for the intervention were found among smokers in the lowest education category (≤11th grade), with a quit rate of 17.3% as compared with 5.7% in usual care (OR=3.5, 95% CI=1.4, 8.6) and in the lowest income range (<$10,000), with a quit rate of 18.7% as compared with 9.4% in usual care (OR=2.2, 95% CI=1.2, 4.0).

CONCLUSIONS

In a large, multicenter smoking-cessation trial, proactive outreach was associated with higher rates of prolonged abstinence among smokers at all SES levels. Proactive outreach interventions that integrate telephone-based care and facilitated cessation medication access have the potential to reduce socioeconomic disparities in quitting.

Trends in educational and income inequalities in cardiovascular morbidity in middle age in Northern Sweden 1993-2010

Aims: Research is scarce regarding studies on income and educational inequality trends in cardiovascular disease in Sweden. The aim of this study was to assess trends in educational and income inequalities in first hospitalizations due to cardiovascular disease (CVD) from 1993 to 2010 among middle-aged women and men in Northern Sweden. Methods: The study comprised repeated cross-sectional register data from year 1993-2010 of all individuals aged 38-62 years enrolled in the Västerbotten Intervention Programme (VIP). Data included highest educational level, total earned income and first-time hospitalization for CVD from national registers. The relative and slope indices of inequality (RII and SII, respectively) were used to estimate educational and income inequalities in CVD for six subsamples for women and men, and interaction analyses were used to estimate trends across time periods. Results: Educational RII and SII were stable in women, while they decreased in men. Income inequalities in CVD developed differently compared with educational inequalities, with RII and SII for both men and women increasing during the study period, the most marked for RII in women rising from 1.52 in the 1990s to 2.62 in the late 2000s. Conclusions: The trend of widening income inequalities over 18 years in the middle-aged in Northern Sweden, in the face of stable or even decreasing educational inequalities, is worrisome from a public health perspective, especially as Swedish authorities monitor socioeconomical inequalities exclusively by education. The results show that certain social inequalities in CVD rise and persist even within a traditionally egalitarian welfare regime.

Decomposition of gendered income-related inequalities in multiple biological cardiovascular risk factors in a middle-aged population

Background

Socioeconomic inequalities in cardiovascular disease seem to widen or endure in Sweden. However, research on inequalities in antecedent cardiovascular risk factors (CVRFs), and particularly what underpins them, is scarce. The present study aimed 1) to estimate income-related inequalities in eight biological cardiovascular risk factors in Swedish middle-aged women and men; and 2) to examine the contribution of demographic, socioeconomic, behavioural and psychosocial determinants to the observed inequalities.

Methods

Participants (N = 12,481) comprised all 40- and 50-years old women and men who participated in the regional Västerbotten Intervention Programme in Northern Sweden during 2008, 2009 and 2010. All participants completed a questionnaire on behavioural and psychosocial conditions, and underwent measurements with respect to eight CVRFs (body mass index; waist circumference; total cholesterol; high-density lipoprotein cholesterol; low-density lipoprotein cholesterol; triglycerides; systolic/diastolic blood pressure; glucose tolerance). Data on cardiovascular risk, psychosocial and health behaviours were linked to national register data on income and other socioeconomic and demographic factors. To estimate income inequalities in each CVRF concentration indexes were calculated, and to examine the contribution of the underlying determinants to the observed inequalities a Wagstaff-type decomposition analysis was performed separately for women and men.

Results

Health inequalities ranged from small to substantial with generally greater magnitude in women. The highest inequalities among women were seen in BMI, triglycerides and HDL-cholesterol (Concentration index = − 0.1850; − 0.1683 and − 0.1479 respectively). Among men the largest inequalities were seen in glucose regulation, BMI and abdominal obesity (Concentration index = − 0.1661; − 0.1259 and − 0.1172). The main explanatory factors were, for both women and men socioeconomic conditions (contributions ranging from 54.8 to 76.7% in women and 34.0–72.6% in men) and health behaviours (contributions ranging from 6.9 to 20.5% in women and 9.2 to 26.9% in men). However, the patterns of specific dominant explanatory factors differed between CVRFs and genders.

Conclusion

Taken together, the results suggest that the magnitude of income-related inequalities in CVRFs and their determinants differ importantly between the risk factors and genders, a variation that should be taken into consideration in population interventions aiming to prevent inequalities in manifest cardiovascular disease.

Socioeconomic status predicts second cardiovascular event in 29,226 survivors of a first myocardial infarction

Background

Risk assessment post-myocardial infarction needs improvement, and risk factors derived from general populations apply differently in secondary prevention. The prediction of subsequent cardiovascular events post-myocardial infarction by socioeconomic status has previously been poorly studied.

Design

Swedish nationwide cohort study.

Methods

A total of 29,226 men and women (27%), 40–76 years of age, registered at the standardised one year revisit after a first myocardial infarction in the secondary prevention quality registry of SWEDEHEART 2006–2014. Personal-level data on socioeconomic status measured by disposable income and educational level, marital status, and the primary endpoint, first recurrent event of atherosclerotic cardiovascular disease, defined as non-fatal myocardial infarction or coronary heart disease death or fatal or non-fatal stroke were obtained from linked national registries.

Results

During the mean 4.1-year follow-up, 2284 (7.8%) first recurrent manifestations of atherosclerotic cardiovascular disease occurred. Both socioeconomic status indicators and marital status were associated with the primary endpoint in multivariable Cox regression models. In a comprehensively adjusted model, including secondary preventive treatment, the hazard ratio for the highest versus lowest quintile of disposable income was 0.73 (95% confidence interval 0.62–0.83). The association between disposable income and first recurrent manifestation of atherosclerotic cardiovascular disease was stronger in men as was the risk associated with being unmarried (tests for interaction P < 0.05).

Conclusions

Among one year survivors of a first myocardial infarction, first recurrent manifestation of atherosclerotic cardiovascular disease was predicted by disposable income, level of education and marital status. The association between disposable income and first recurrent manifestation of atherosclerotic cardiovascular disease was independent of secondary preventive treatment but further study on causal pathways is needed.

Expanded cardiac rehabilitation in socially vulnerable patients with myocardial infarction: a 10-year follow-up study focusing on mortality and non-fatal events

OBJECTIVE

Cardiac rehabilitation (CR) has been shown to reduce cardiovascular risk. A research project performed at a university hospital in Denmark offered an expanded CR intervention to socially vulnerable patients. One-year follow-up showed significant improvements concerning medicine compliance, lipid profile, blood pressure and body mass index when compared with socially vulnerable patients receiving standard CR. The aim of the study was to perform a long-term follow-up on the socially differentiated CR intervention and examine the impact of the intervention on all-cause mortality, cardiovascular mortality, non-fatal recurrent events and major cardiac events (MACE) 10 years after.

DESIGN

Prospective cohort study.

SETTING

The cardiac ward at a university hospital in Denmark from 2000 to 2004.

PARTICIPANTS

379 patients aged <70 years admitted with first episode myocardial infarction (MI). The patients were defined as socially vulnerable or non-socially vulnerable according to their educational level and their social network. A complete follow-up was achieved.

INTERVENTION

A socially differentiated CR intervention. The intervention consisted of standard CR and additionally a longer phase II course, more consultations, telephone follow-up and a better handover to phase III CR in the municipal sector, in general practice and in the patient association.

MAIN OUTCOME MEASURES

All-cause mortality, cardiovascular mortality, non-fatal recurrent events and MACE.

RESULTS

There was no significant difference in all-cause mortality (OR: 1.29, 95% CI 0.58 to 2,89), cardiovascular mortality (OR: 0.80, 95% CI 0.31 to 2.09), non-fatal recurrent events (OR:1.62, 95% CI 0.67 to 3.92) or MACE (OR: 1.31, 95% CI 0.53 to 2.42) measured at 10-year follow-up when comparing the expanded CR intervention to standard CR.

CONCLUSIONS

Despite the significant results of the socially differentiated CR intervention at 1-year follow-up, no long-term effects were seen regarding the main outcome measures at 10-year follow-up. Future research should focus on why it is not possible to lower the mortality and morbidity significantly among socially vulnerable patients admitted with first episode MI.

The MOTIV-HEART Study: A Prospective, Randomized, Single-Blind Pilot Study of Brief Strategic Therapy and Motivational Interviewing among Cardiac Rehabilitation Patients

Background: Psychological distress, biomedical parameters, and unhealthy lifestyles contribute to a poorer prognosis for cardiac disease. Public health's challenge is to motivate patients to utilize self-care. Objective: This prospective, randomized, single-blind pilot study aimed at testing the incremental efficacy of Brief Strategic Therapy (BST) combined with Motivational Interviewing (MI) in improving selected biomedical and psychological outcomes over and beyond those of the stand-alone BST in a residential Cardiac Rehabilitation (CR) program. Method: Fourty-two inpatients (17 females), enrolled in a 1-month CR program, were randomly allocated into two conditions: (a) Three sessions of BST and (b) Three sessions of BST plus MI. Data were collected at baseline, discharge, and after 3 months through phone interviews. Results: At discharge, no significant between-group difference was found in any outcome variable. Changes from pre- to post-treatment within each condition showed significant improvements only in the BST group, where the level of external regulation diminished, and both the participants' self-regulation (Relative Autonomous Motivation Index, RAI) and willingness to change improved. At the 3-month follow-up, within-group analyses on responders (BST = 9; BST + MI = 11) showed a statistically significant improvement in the level of systolic blood pressure in both groups. Discussion: Findings showed no evidence of the incremental efficacy of combining BST and MI over and beyond BST alone on either selected biomedical or psychological outcomes among CR patients. Conclusions: Ends and limitations from the present pilot study should be considered and addressed in future investigations.

Smoking on the margins: a comprehensive analysis of a municipal outdoor smoke-free policy

BACKGROUND

This study examined the formulation, adoption, and implementation of a ban on smoking in the parks and beaches in Vancouver, Canada.

METHODS

Informed by Critical Multiplism, we explored the policy adoption process, support for and compliance with a local bylaw prohibiting smoking in parks and on beaches, experiences with enforcement, and potential health equity issues through a series of qualitative and quantitative studies.

RESULTS

Findings suggest that there was unanimous support for the introduction of the bylaw among policy makers, as well as a high degree of positive public support. We observed that smoking initially declined following the ban's implementation, but that smoking practices vary in parks by location. We also found evidence of different levels of enforcement and compliance between settings, and between different populations of park and beach users.

CONCLUSIONS

Overall success with the implementation of the bylaw is tempered by potential increases in health inequities because of variable enforcement of the ban; greatest levels of smoking appear to continue to occur in the least advantaged areas of the city. Jurisdictions developing such policies need to consider how to allocate sufficient resources to enhance voluntary compliance and ensure that such bylaws do not contribute to health inequities.

Social support and self-management capabilities in diabetes patients: An international observational study

OBJECTIVE

The objective of this study was to explore which aspects of social networks are related to self-management capabilities and if these networks have the potential to reduce the adverse health effects of deprivation.

METHODS

In a cross-sectional study we recruited type 2 diabetes patients in six European countries. Data on self-management capabilities was gathered through written questionnaires and data on social networks characteristics and social support through subsequent personal/telephone interviews. We used regression modelling to assess the effect of social support and education on self-management capabilities.

RESULTS

In total 1692 respondents completed the questionnaire and the interview. Extensive informational networks, emotional networks, and attendance of community organisations were linked to better self-management capabilities. The association of self-management capabilities with informational support was especially strong in the low education group, whereas the association with emotional support was stronger in the high education group.

CONCLUSION

Some of the social network characteristics showed a positive relation to self-management capabilities. The effect of informational support was strongest in low education populations and may therefore provide a possibility to reduce the adverse impact of low education on self-management capabilities.

PRACTICE IMPLICATIONS

Self-management support interventions that take informational support in patients' networks into account may be most effective, especially in deprived populations.

A cohort study: temporal trends in prevalence of antecedents, comorbidities and mortality in Aboriginal and non-Aboriginal Australians with first heart failure hospitalization, 2000-2009

BACKGROUND/OBJECTIVES

Little is known about trends in risk factors and mortality for Aboriginal Australians with heart failure (HF). This population-based study evaluated trends in prevalence of risk factors, 30-day and 1-year all-cause mortality following first HF hospitalization among Aboriginal and non-Aboriginal Western Australians in the decade 2000-2009.

METHODS

Linked-health data were used to identify patients (20-84 years), with a first-ever HF hospitalization. Trends in demographics, comorbidities, interventions and risk factors were evaluated. Logistic and Cox regression models were fitted to test and compare trends over time in 30-day and 1-year mortality.

RESULTS

Of 17,379 HF patients, 1,013 (5.8%) were Aboriginal. Compared with 2000-2002, the prevalence (as history) of myocardial infarction and hypertension increased more markedly in 2006-2009 in Aboriginal (versus non-Aboriginal) patients, while diabetes and chronic kidney disease remained disproportionately higher in Aboriginal patients. Risk factor trends, including the Charlson comorbidity index, increased over time in younger Aboriginal patients. Risk-adjusted 30-day mortality did not change over the decade in either group. Risk-adjusted 1-year mortality (in 30-day survivors) was non-significantly higher in Aboriginal patients in 2006-2008 compared with 2000-2002 (hazard ratio (HR) 1.44; 95% CI 0.85-2.41; p-trend = 0.47) whereas it decreased in non-Aboriginal patients (HR 0.87; 95% CI 0.78-0.97; p-trend = 0.01).

CONCLUSIONS

Between 2000 and 2009, the prevalence of HF antecedents increased and remained disproportionately higher in Aboriginal (versus non-Aboriginal) HF patients. Risk-adjusted 1-year mortality did not improve in Aboriginal patients over the period in contrast with non-Aboriginal patients. These findings highlight the need for better prevention and post-HF care in Aboriginal Australians.

The association of income with health behavior change and disease monitoring among patients with chronic disease

BACKGROUND

Management of chronic diseases requires patients to adhere to recommended health behavior change and complete tests for monitoring. While studies have shown an association between low income and lack of adherence, the reasons why people with low income may be less likely to adhere are unclear. We sought to determine the association between household income and receipt of health behavior change advice, adherence to advice, receipt of recommended monitoring tests, and self-reported reasons for non-adherence/non-receipt.

METHODS

We conducted a population-weighted survey, with 1849 respondents with cardiovascular-related chronic diseases (heart disease, hypertension, diabetes, stroke) from Western Canada (n = 1849). We used log-binomial regression to examine the association between household income and the outcome variables of interest: receipt of advice for and adherence to health behavior change (sodium reduction, dietary improvement, increased physical activity, smoking cessation, weight loss), reasons for non-adherence, receipt of recommended monitoring tests (cholesterol, blood glucose, blood pressure), and reasons for non-receipt of tests.

RESULTS

Behavior change advice was received equally by both low and high income respondents. Low income respondents were more likely than those with high income to not adhere to recommendations regarding smoking cessation (adjusted prevalence rate ratio (PRR): 1.55, 95%CI: 1.09-2.20), and more likely to not receive measurements of blood cholesterol (PRR: 1.72, 95%CI 1.24-2.40) or glucose (PRR: 1.80, 95%CI: 1.26-2.58). Those with low income were less likely to state that non-adherence/non-receipt was due to personal choice, and more likely to state that it was due to an extrinsic factor, such as cost or lack of accessibility.

CONCLUSIONS

There are important income-related differences in the patterns of health behavior change and disease monitoring, as well as reasons for non-adherence or non-receipt. Among those with low income, adherence to health behavior change and monitoring may be improved by addressing modifiable barriers such as cost and access.

Lifestyle advice and lifestyle change: to what degree does lifestyle advice of healthcare professionals reach the population, focusing on gender, age and education?

Health promotion practice in health care has a high priority in the endeavour to achieve equal opportunities for health and diversity in health among the population. The purpose of the study was to investigate whether there is any connection between the lifestyle advice given by healthcare professionals and the lifestyle change of the population, focusing on age, gender and education level. The study is based on the data from a national population survey in Sweden in which 52 595 patients who had attended health care were interviewed by phone. The participants were asked whether healthcare professionals had raised the subject of lifestyle during the visit and whether the advice they gave had contributed to a lifestyle change. The results indicated that lifestyle issues were raised with 32.2% of those who attended health care, particularly among men, younger patients and those with a high education level. When lifestyle issues were raised, the advice contributed to 39.2% of patients making a lifestyle change, to a higher extent among men, older patients and those with a low education level. The study shows that lifestyle advice given by healthcare professionals, during both emergency and outpatient healthcare visits, is an important contributor to patients' lifestyle change.

Describing self-care in Italian adults with heart failure and identifying determinants of poor self-care

BACKGROUND

Self-care improves outcomes in patients with heart failure; however, no studies have been conducted on this topic in Italy.

AIMS

We aimed to describe self-care in Italian adults with heart failure and to identify sociodemographic and clinical determinants of self-care.

METHODS

A cross-sectional design was used to study 1192 heart failure patients enrolled across Italy. We measured self-care using the Self-Care of Heart Failure Index version 6.2, which measures self-care maintenance, management and confidence. Sociodemographic and clinical data were tested as potential determinants of self-care.

RESULTS

The mean age of the sample was 72 (SD = 11) years; 58% were male. In the three areas of self-care, scores ranged from 53.18 to 55.26 and few people were adequate in self-care (14.5% to 24.4% of the sample). Self-care behaviours particularly low in this population were symptom monitoring, exercise, use of reminders to take medicines and symptom recognition. Confidence in the ability to keep oneself free of symptoms and relieve symptoms was low. Taking fewer medications, poor cognition, older age, having a caregiver, being male and having heart failure for a shorter time predicted poor self-care maintenance. Poor cognition, not being employed, being male, and having worse New York Heart Association class predicted poor self-care management. Poor cognition, taking fewer mediations, older age, and male gender predicted poor self-care confidence.

CONCLUSION

Self-care is poor in Italian heart failure patients. Determinants of poor self-care identified in this study can help to target patients' education. Male gender and poor cognition were consistently associated with poor self-care maintenance, management and confidence.

A prospective examination of disease management program use by complex cardiac outpatients

BACKGROUND

The use of disease management programs (DMPs) by patients with cardiovascular disease (CVD) is associated with improved outcomes. Although rates of cardiac rehabilitation (CR) use are well established, less is known about other DMPs. The objectives of this study were to describe the degree of DMP utilization by CVD outpatients, and examine factors related to use.

METHODS

This study represents a secondary analysis of a larger prospective cohort study. In hospital, 2635 CVD inpatients from 11 hospitals in Ontario Canada completed a survey that assessed factors affecting DMP utilization. One year later, 1803 participants completed a mailed survey that assessed DMP utilization.

RESULTS

One thousand seventy-three (59.5%) participants reported using at least 1 DMP. Overall, 951 (52.7%) reported participating in cardiac rehabilitation, and among participants with a comorbid indication, 212 (41.2%) reported attending a diabetes education centre, 28 (25.9%) attended stroke rehabilitation, 35 (12.9%) used a heart failure clinic, and 13 (11.7%) attended a smoking cessation program. A multinomial logistic regression analysis showed that compared with no DMP use, participants that attended 1 or multiple programs were younger, married, diagnosed with a myocardial infarction, less likely to have had a percutaneous coronary intervention and had higher perceptions of personal control over their heart condition. There were few differences between participants that used 1 vs multiple DMPs, however, having diabetes or comorbid stroke significantly increased the likelihood of multiple DMP use.

CONCLUSIONS

Approximately 40% of CVD outpatients do not access DMPs. An integrated approach to vascular disease management appears warranted.

Prevalence of isolated atrial amyloidosis in young patients affected by congestive heart failure

Atrial natriuretic peptide (ANP), whose amyloid is responsible of isolated atrial amyloidosis (IAA), is known to play an important role in the pathophysiology of congestive heart failure (CHF). We provide here the microscopic examination of atrial biopsies from 36 young (mean 40 years) CHF patients distinguished in idiopathic dilated cardiomyopathy (DC) affected and hypertrophic Cardiomyopathy (HC) affected, endorsing the presumptive association of early CHF with IAA. We utilized a multiple method, using Congo red (CR) staining, CR fluorescence (CRF), and immunohistochemistry to assess the presence of IAA in CHF. Immunostaining showed a moderate deposition of IAA in the atrium surrounding working myocardium with small intracellular deposits. Our findings suggest a monitoring of young CHF cases for the development of IAA. Our study also demonstrated how the concurrent use of immunohistochemistry, CR, and CRF may greatly enhance the detection of low-grade amyloid deposits.

Research agenda for tackling inequalities related to migration and ethnicity in Europe

Reducing ethnic inequalities and inequities in health needs to become a higher priority for public health research. Active involvement of migrant and ethnic minority populations in European population health research is necessary, for data show important inequalities but evidence, particularly on effectiveness, is sparse and strategic overviews rarer still. Ethnically disaggregated health surveillance systems are developing slowly, and pragmatically, often using country of birth. The principles to adopt, given the gaps between the ideal and the current reality, need wider discussion. Ethics may provide both principles and impetus. Doing no harm, doing good, respecting the research participants' autonomy are good starting points. More emphasis is needed on justice, fairness and equality, participation and communicating effectively. Ethnic minority groups are willing participants in trials once linguistic and trust-related barriers are overcome, though recruitment costs are higher. Guidelines and strategies by European bodies with research funding or enforcement responsibilities are needed. The research community needs an infrastructure within which to collect and utilize evidence. Research can help migrant and ethnic minority groups to participate more fully in our multi-ethnic societies.

Screening for cardiovascular disease risk factors in an urban low-income setting at baseline and post intervention: a prospective intervention study

BACKGROUND

Not all segments of society might have equal access to screening. We determined predictors for regular cardiovascular health screening at baseline amongst those of low socioeconomic status (SES) and evaluated the effectiveness of a 6-month intervention on screening in this group compared to a high-SES group.

METHODS

The study population involved all residents aged ≥ 40 years in two housing estates comprising owner-occupied housing (high SES) and rental flats (low SES) in Singapore. From 2009 to 2011, residents not being screened regularly at baseline for hypertension, diabetes, and dyslipidaemia were offered free and convenient blood pressure, fasting blood glucose, and lipid testing over 6 months. Chi-squared and multi-level logistic regression identified predictors of regular screening at baseline; likelihood ratio and Cox regression analysis identified predictors of screening participation post intervention.

RESULTS

Participation was 78.2% (1081/1383). At baseline, in the low-SES group, 41.7% (150/360), 38.8% (177/456), and 30.8% (128/416) had gone for regular hypertension, diabetes, and dyslipidaemia screening, respectively; compared with higher numbers in the high-SES group. Sociodemographic factors predicting regular screening in the low-SES community included being married and not smoking. Post intervention, screening rates rose significantly (p < 0.001) by similar proportions in both communities. Staying in a lower-SES community (adjusted relative risk (aRR) 0.61, 95% CI 0.37-0.99, p = 0.048) and having hypertension (aRR 0.45, 95% CI 0.18-0.98, p = 0.049) was associated with lower take-up; Chinese ethnicity (aRR 1.84, 95% CI 1.00-3.43, p = 0.050) and employment associated with higher take-up (aRR 1.57, 95% CI 1.03-2.60, p = 0.040).

CONCLUSION

Participation in cardiovascular health screening was poor amongst those of low SES; a 6-month intervention programme improved participation in this population.

Cardiovascular disease and risk factors in an indigenous minority population. The All-Ireland Traveller Health Study

BACKGROUND

The Traveller community are an indigenous minority group in Great Britain and Ireland who experience premature mortality. While minority populations worldwide are known to have high rates of risk factors for cardiovascular disease (CVD), Traveller CVD risk has not previously been defined.

DESIGN

All-Ireland cross-sectional census survey of the Traveller minority population (n = 10,615 families).

METHODS

A subsample of adult respondents completed a health survey (n = 2023). CVD was defined as self-report of doctor-diagnosed heart attack, angina, or stroke. CVD risk factors and measures of social position were examined in the Traveller group using age-adjusted prevalence and prevalence ratios (PR). Comparisons were made with a general population sample of low socioeconomic status.

RESULTS

Age-adjusted prevalence of CVD in the Traveller population was 5.6% (95% CI 4.6-6.8), similar to that in the comparator population. Compared to those without CVD, Travellers with CVD had a higher prevalence of self-report of diabetes, hypertension, hypercholesterolaemia, current smoking, and a measure of distrust. Compared with the general population sample, Travellers had a higher prevalence of diabetes (adjusted PR 2.8, 95% CI 2.1-3.8) and lifestyle-related risk factors such as smoking (PR 1.3, 95% CI 1.2-1.4), fried food consumption (PR 2.8, 95% CI 2.4-3.2), and physical inactivity (PR 1.3, 95% CI 1.2-1.4).

CONCLUSIONS

This comprehensive census survey confirms CVD as an important health risk in the economically disadvantaged Irish Traveller community. Our findings add to the international knowledge base on minority populations and CVD risk.

A systematic review and meta-analysis of the effectiveness of behavioural smoking cessation interventions in selected disadvantaged groups

AIMS

A systematic review and meta-analysis was conducted to assess the methodological quality and effectiveness of behavioural smoking cessation interventions targeted at six disadvantaged groups; the homeless, prisoners, indigenous populations, at-risk youth, individuals with low socio-economic status and individuals with a mental illness.

METHODS

Medline, EMBASE, the Cochrane Library and PsycInfo databases were searched using MeSH and keywords for studies conducted in developed countries prior to October 2010. Included studies were assessed for methodological quality. A DerSimonian and Laird random effects meta-analysis was conducted where possible to explore the effectiveness of interventions for the different subgroups. A narrative review was conducted for studies unable to be included in the meta-analysis. Outcomes examined were abstinence rates at short-term (up to 3 months) and long-term (6 months or the longest) follow-up.

RESULTS

Thirty-two relevant studies were identified. The majority (n = 20) were rated low in methodological quality. Results of the meta-analysis showed a significant increase in cessation for behavioural support interventions targeted at low-income female smokers at short-term follow-up [relative risk (RR) 1.68, confidence interval (CI) 1.21-2.33], and behavioural support interventions targeted at individuals with a mental illness at long-term follow-up (RR 1.35, CI 1.01-1.81). Results of the narrative review showed several promising interventions that increased cessation rates at 6-month or longer follow-up.

CONCLUSIONS

Few well-controlled trials have examined the most effective smoking cessation strategies for highly disadvantaged groups, especially among the homeless, indigenous smokers and prisoners. The use of behavioural smoking cessation interventions for some socially disadvantaged groups appears promising; however, overall findings are inconsistent. Further research is needed to establish the most effective interventions for vulnerable high-risk groups. Special attention should be given to increasing sample size and power, and to sound evaluation methodology to overcome methodological limitations of conducting research with these high-risk groups.

Mortality, incidence of cardiovascular diseases, and educational level among the diabetic and non-diabetic populations in two large Italian cities

AIMS

We investigated if diabetes modifies the effect of the association of education with mortality and incidence of cardiovascular diseases.

METHODS

We identified 44,889 diabetics using multiple data sources. They were followed up from January 2002 up to December 2005, and their mortality, incidence of myocardial infarction and stroke, by educational level were analysed, and compared with those of the local non-diabetic population.

RESULTS

The all-cause Standardized Mortality Ratios among diabetics, compared with non-diabetics, were 170 for men and 175 for women. Standardized Incidence Ratios were 199 for myocardial infarction, and 183 for stroke in men and, respectively, 281, and 179 in women. Among non-diabetics there was a clear inverse relation with educational level for all outcomes, whereas among diabetics no significant social difference in incidence was found; slight social differences in mortality were present among men, but not among women. The effect of diabetes on social differences was enhanced in the youngest population.

CONCLUSIONS

Diabetes increases the risk of death and the incidence of vascular diseases, but reduces their inverse association with education. This is likely related to the high accessibility and good quality of health care provided by the local networks of diabetic centres and primary care.

Social determinants of cardiac disease biomarkers: investigating a Swedish male cohort at ages 50 and 70

BACKGROUND

Social status is associated with cardiovascular disease (CVD) prevalence and incidence.

AIMS

to investigate relationships between socioeconomic position (SEP) and common CVD biomarkers including adiponectin not previously investigated in a Swedish-population sample, and to assess if these associations changed with age.

DESIGN

Population-based longitudinal cohort study of men born 1920-24 with clinical measurements, blood samples, questionnaire data, and register-based information on SEP and cause of death.

METHODS

A total of 2322 men attended an investigation at age 50 of which 1221 attended a reinvestigation at age 70. Association between SEP and CVD biomarkers [cholesterol, low-density lipoprotein/high-density lipoprotein (LDL/HDL), apolipoprotein (Apo) ApoB/ApoA1, and adiponectin] were analysed by linear regression (adjusted for age, body mass index, and physical activity). SEP was measured as occupational class and educational level. CVD mortality over 36 years of follow-up was analysed by Cox regression.

RESULTS

At age 50, we found a significant inverse association of education with cholesterol level, LDL/HDL ratio and ApoB/ApoA1 ratio. Cholesterol was also associated with occupational class, statistically significant after adjustment for all covariates. At age 70, no significant associations were found between either measurement of SEP and any of the biomarkers studied. Highest educated men had decreased risk for CVD mortality during follow-up.

CONCLUSIONS

Associations of SEP with cholesterol levels and LDL/HDL ratio that exist at age 50 are no longer apparent in the same group of men at age 70. We found no significant association between SEP and adiponectin levels at age 70.
