ABSTRACT

Cardiovascular disease remains the leading cause of death in patients with diabetes. Cardiovascular disease in diabetes is multifactorial, and control of the cardiovascular risk factors leads to substantial reductions in cardiovascular events. The 2015 American Heart Association and American Diabetes Association scientific statement, "Update on Prevention of Cardiovascular Disease in Adults With Type 2 Diabetes Mellitus in Light of Recent Evidence," highlighted the importance of modifying various risk factors responsible for cardiovascular disease in diabetes. At the time, there was limited evidence to suggest that glucose-lowering medications reduce the risk of cardiovascular events. At present, several large randomized controlled trials with newer antihyperglycemic agents have been completed, demonstrating cardiovascular safety and reduction in cardiovascular outcomes, including cardiovascular death, myocardial infarction, stroke, and heart failure. This AHA scientific statement update focuses on (1) the evidence and clinical utility of newer antihyperglycemic agents in improving glycemic control and reducing cardiovascular events in diabetes; (2) the impact of blood pressure control on cardiovascular events in diabetes; and (3) the role of newer lipid-lowering therapies in comprehensive cardiovascular risk management in adults with diabetes. This scientific statement addresses the continued importance of lifestyle interventions, pharmacological therapy, and surgical interventions to curb the epidemic of obesity and metabolic syndrome, important precursors of prediabetes, diabetes, and comorbid cardiovascular disease. Last, this scientific statement explores the critical importance of the social determinants of health and health equity in the continuum of care in diabetes and cardiovascular disease.

ABSTRACT

PURPOSE: Despite higher rates of modifiable risk factors for cardiovascular disease (CVD) in gay and bisexual men, few studies have examined sexual orientation differences in CVD among men. The purpose of this study was to examine sexual orientation differences in modifiable risk factors for CVD and CVD diagnoses in men. METHODS: A secondary analysis of the National Health and Nutrition Examination Survey (2001-2012) was conducted. Multiple imputation was performed for missing values. Differences across four distinct groups were analyzed: gay-identified men, bisexual-identified men, heterosexual-identified men who have sex with men (MSM), and heterosexual-identified men who denied same-sex behavior (categorized as exclusively heterosexual). Multiple logistic regression models were run with exclusively heterosexual men as the reference group. RESULTS: The analytic sample consisted of 7731 men. No differences between heterosexual-identified MSM and exclusively heterosexual men were observed. Few differences in health behaviors were noted, except that, compared to exclusively heterosexual men, gay-identified men reported lower binge drinking (adjusted odds ratio [AOR] 0.58, 95% confidence interval [CI] = 0.37-0.85). Bisexual-identified men had higher rates of mental distress (AOR 2.39, 95% CI = 1.46-3.90), obesity (AOR 1.69, 95% CI = 1.02-2.72), elevated blood pressure (AOR 2.30, 95% CI = 1.43-3.70), and glycosylated hemoglobin (AOR 3.01, 95% CI = 1.38-6.59) relative to exclusively heterosexual men. CONCLUSIONS: Gay-identified and heterosexual-identified MSM demonstrated similar CVD risk to exclusively heterosexual men, whereas bisexual-identified men had elevations in several risk factors. Future directions for sexual minority health research in this area and the need for CVD and mental health screenings, particularly in bisexual-identified men, are highlighted.

ABSTRACT

BACKGROUND: The American Heart Association's (AHA) Council on Cardiovascular and Stroke Nursing (CVSN) plays a critical role in advancing the mission of the AHA in the discovery of new scientific knowledge. The aim was to identify priority research topics that would promote and improve cardiovascular (CV) health, provide direction for the education of future nurse scientists, and serve as a resource and catalyst for federal and organizational funding priorities. METHODS: A Qualtrics survey, which included 3 questions about priorities for CVSN nurse researchers, was sent to the CVSN Leadership Committee and all CVSN Fellows of the AHA (n = 208). Responses to the questions were reviewed for word repetitions, patterns, and concepts and were then organized into thematic areas. The thematic areas were reviewed within small groups at the November (2016) in-person CVSN leadership meeting. RESULTS: Seventy-three surveys were completed. Five thematic areas were identified and included (1) developing and testing interventions, (2) assessment and monitoring, (3) precision CV nursing care, (4) translational and implementation science, and (5) big data. Topic areas noted were stroke, research methods, prevention of stroke and CV disease, self-management, and care and health disparities. CONCLUSION: Five thematic areas and 24 topic areas were identified as priorities for CV nursing research. These findings can provide a guide for CV nurse scientists and for federal and foundational funders to use in developing funding initiatives. We believe additional research and discovery in these thematic areas will help reduce the rising global burden of CV disease.

ABSTRACT

OBJECTIVE: Sexual minority women (lesbian and bisexual) experience significant stigma, which may increase their cardiovascular disease (CVD) risk. The purpose of this study was to examine the prevalence of modifiable risk factors for CVD (including mental distress, health behaviors, blood pressure, glycosylated hemoglobin, and total cholesterol) and CVD in sexual minority women compared with their heterosexual peers. MATERIALS AND METHODS: A secondary analysis of the National Health and Nutrition Examination Survey (2001-2012) was conducted. Multiple imputation with chained equations was performed. Logistic regression models adjusted for relevant covariates were run. Self-report (medical history and medication use) and biomarkers for hypertension, diabetes, and high total cholesterol were examined. RESULTS: The final analytic sample consisted of 7,503 that included 346 sexual minority women (4.6%). Sexual minority women were more likely to be younger, single, have a lower income, and lack health insurance. After covariate adjustment, sexual minority women exhibited excess CVD risk related to higher rates of frequent mental distress (adjusted odds ratio [AOR], 2.05; 95% confidence interval [CI], 1.45-2.88), current tobacco use (AOR, 2.11; 95% CI, 1.53-2.91), and binge drinking (AOR, 1.66; 95% CI, 1.17-2.34). Sexual minority women were more likely to be obese (AOR, 1.61; 95% CI, 1.23-2.33) and have glycosylated hemoglobin consistent with prediabetes (AOR, 1.56; 95% CI, 1.04-2.34). No differences were observed for other outcomes. CONCLUSIONS: Sexual minority women demonstrated increased modifiable risk factors for CVD, but no difference in CVD diagnoses. Several emerging areas of research are highlighted, in particular, the need for CVD prevention efforts that target modifiable CVD risk in sexual minority women.

ABSTRACT

OBJECTIVE: The aim of this study was to describe (1) nurses' physical and mental health; (2) the relationship between health and medical errors; and (3) the association between nurses' perceptions of wellness support and their health. METHODS: A cross-sectional descriptive survey was conducted with 1790 nurses across the U.S. RESULTS: Over half of the nurses reported suboptimal physical and mental health. Approximately half of the nurses reported having medical errors in the past 5 years. Compared with nurses with better health, those with worse health were associated with 26% to 71% higher likelihood of having medical errors. There also was a significant relationship between greater perceived worksite wellness and better health. CONCLUSION: Wellness must be a high priority for health care systems to optimize health in clinicians to enhance high-quality care and decrease the odds of costly preventable medical errors.

ABSTRACT

AIMS: Diabetes affects 29 million adults, and the majority have type 2 diabetes (T2D). Coronary artery disease (CAD) is the leading cause of death, and physical inactivity is an important risk factor. The aims of this study were to examine the contribution of physical inactivity to CAD events, and to identify the independent predictors of CAD events in a sample of older adults with T2D. METHOD: A secondary data analysis of the prospective randomized screening trial "Detection of Ischemia in Asymptomatic Diabetics (DIAD)" study. Cox proportional hazard modeling was used to examine the outcome of CAD events. RESULTS: During the five years of follow-up, the CAD event rate for all subjects (n = 1119) was 8.4% (n = 94). In unadjusted analysis, physical inactivity was significantly associated with development of a CAD event. In the final model, nine baseline variables were significant predictors (p < 0.05) of a CAD: physical inactivity, race, diabetes duration, hemoglobin A1c (HbA1c), peripheral numbness, insulin use, increasing waist-to-hip ratio, family history of premature CAD, and a higher pulse pressure. In men only, there were five predictors (p < 0.05) of a CAD event: diabetes duration, peripheral numbness, HbA1c, increasing waist-to-hip ratio, and higher pulse pressure. The final model in women included three independent predictors (p < 0.05) of a CAD event: diabetes duration, a family history of premature CAD, and higher pulse pressure. CONCLUSION: Several variables predicted CAD events in this sample of older adults with T2D. Understanding baseline characteristics that heighten risk may assist providers in intervening early to prevent its occurrence.

ABSTRACT

PURPOSE: The primary aim of this study was to assess the feasibility of an exercise counseling intervention for adults of diverse race/ethnicity with heart failure (HF) and to assess its potential for improving overall physical activity, functional capacity, and HF self-care. DESIGN: This study was a quasi-experimental, prospective, longitudinal cohort design. METHODS: Twenty adults were enrolled and completed the 6-minute walk and standardized instruments, followed by exercise counseling using motivational interviewing. Each received an accelerometer, hand weights, and a diary to record self-care behaviors. Participants were followed via phone for 12 weeks to collect step-counts, review symptoms, and plan the following week's step goal. FINDINGS: Results indicate that this intervention was feasible for most participants and resulted in improvements in physical activity, functional capacity, and self-care behaviors. CONCLUSION/CLINICAL RELEVANCE: Brief exercise counseling may be an appropriate option to improve outcomes for stable patients with HF and may be tailored to fit different settings.

ABSTRACT

The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease (CVD) is the leading cause of death and major disability in adults aged 75 and older. Despite the effect of CVD on quality of life, morbidity, and mortality in older adults, individuals aged 75 and older have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older adults with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in nursing homes and assisted living facilities. As a result, current guidelines are unable to provide evidence-based recommendations for diagnosis and treatment of older adults typical of those encountered in routine clinical practice. The objectives of this scientific statement are to summarize current guideline recommendations as they apply to older adults, identify critical gaps in knowledge that preclude informed evidence-based decision-making, and recommend future research to close existing knowledge gaps. To achieve these objectives, a detailed review was conducted of current American College of Cardiology/American Heart Association (ACC/AHA) and American Stroke Association (ASA) guidelines to identify content and recommendations that explicitly targeted older adults. A pervasive lack of evidence to guide clinical decision-making in older adults with CVD was found, as well as a paucity of data on the effect of diagnostic and therapeutic interventions on outcomes that are particularly important to older adults, such as quality of life, physical function, and maintenance of independence. Accordingly, there is a critical need for a multitude of large population-based studies and clinical trials that include a broad spectrum of older adults representative of those seen in clinical practice and that incorporate relevant outcomes important to older adults in the study design. The results of these studies will provide the foundation for future evidence-based guidelines applicable to older adults and enhance person-centered care of older individuals with CVD in the United States and around the world.

ABSTRACT

The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease is the leading cause of death and major disability in adults ≥75 years of age; however, despite the large impact of cardiovascular disease on quality of life, morbidity, and mortality in older adults, patients aged ≥75 years have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older patients with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in a nursing home or assisted living facility. As a result, current guidelines are unable to provide evidence-based recommendations for diagnosis and treatment of older patients typical of those encountered in routine clinical practice. The objectives of this scientific statement are to summarize current guideline recommendations as they apply to older adults, identify critical gaps in knowledge that preclude informed evidence-based decision making, and recommend future research to close existing knowledge gaps.

ABSTRACT

The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease is the leading cause of death and major disability in adults ≥75 years of age; however, despite the large impact of cardiovascular disease on quality of life, morbidity, and mortality in older adults, patients aged ≥75 years have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older patients with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in a nursing home or assisted living facility.

ABSTRACT

AIM: To describe the results of the process evaluation of an exercise counseling intervention using motivational interviewing (MI). BACKGROUND: Exercise can safely be incorporated into heart failure self-care, but many lack access to cardiac rehabilitation. One alternative is to provide exercise counseling in the clinical setting. METHODS: This process evaluation was conducted according to previously established guidelines for health promotion programs. This includes an assessment of recruitment and retention, implementation, and reach. RESULTS: Desired number of subjects were recruited, but 25% dropped out during study. Good fidelity to the intervention was achieved; the use of MI was evaluated with improvement in adherence over time. Dose included initial session plus 12 weekly phone calls. Subjects varied in participation of daily diary usage. Setting was conducive to recruitment and data collection. CONCLUSIONS: Evaluating the process of an intervention provides valuable feedback on content, delivery and fidelity.

ABSTRACT

OBJECTIVE: The primary aim of this secondary analysis was to determine whether cardiac autonomic neuropathy independently predicted adverse cardiac outcomes in asymptomatic individuals with type 2 diabetes. Additional aims include the determination of the correlation of standard autonomic testing measures and power spectral analysis of heart rate variability, and the association of diabetes-related and cardiac risk factors with cardiac autonomic neuropathy measures. METHODS: Cardiac autonomic neuropathy was assessed at the study entry into the Detection of Ischemia in Asymptomatic Diabetics study, using autonomic heart rate and blood pressure testing, and power spectral analysis of heart rate variability. All participants were prospectively followed for the composite clinical outcome of cardiac death, acute coronary syndromes, heart failure, or coronary revascularization. RESULTS: Over 5 years of follow-up, 94 of 1119 (8.4%) subjects developed symptomatic cardiac disease. In unadjusted bivariate analyses, abnormalities in several cardiac autonomic neuropathy tests, including lower Valsalva and Standing Heart Rate Ratios, higher resting Heart Rate, greater systolic blood pressure decrease on standing, and lower low-frequency power, were predictive of symptomatic disease. Independent predictors of poor cardiac outcome were a lower Valsalva Heart Rate Ratio, non-Black ethnicity, longer diabetes duration, higher glycated hemoglobin (HbA1c), insulin use, reported numbness in the extremities, higher pulse pressure, family history of coronary artery disease, and higher waist-to-hip ratio. Clinical factors independently associated with a lower Valsalva Heart Rate Ratio were insulin use, clinical proteinuria, higher pulse pressure, use of angiotensin-converting enzyme inhibitor and non-Black ethnicity. CONCLUSION: Cardiac autonomic neuropathy predicted adverse cardiac outcomes in asymptomatic type 2 diabetes without known cardiac disease. Clinical variables may help to identify patients who might have cardiac autonomic neuropathy and warrant consideration for autonomic testing.

ABSTRACT

PURPOSE: The purpose of this secondary analysis was to determine changes in physical inactivity from baseline to 5 years and to identify factors associated with and predictive of physical inactivity among individuals with type 2 diabetes enrolled in the Detection of Ischemia in Asymptomatic Diabetics (DIAD) study. METHODS: DIAD was a prospective randomized screening trial that assessed the prevalence of silent ischemia in asymptomatic patients with type 2 diabetes. Subjects were recruited from diabetes and primary care practices at 14 centers throughout the United States and Canada. This is a secondary data analysis of the physical activity data (type and hours/week) collected. No intervention was conducted. RESULTS: In all subjects, physical inactivity rose from 24% at baseline to 33% at 5 years (S = 28.93; P < .0001). This change was significant in both men (S = 11.44; P < .0001), increasing from 23% to 31%, and women (S = 18.05; P < .0001), increasing from 25% to 36%. Gender differences were noted in several factors associated with baseline physical inactivity as well as in factors predictive of physical inactivity at 5 years. Important factors associated at both time points included lower level of education, current employment, presence of peripheral and autonomic neuropathy, and indicators of overweight/obesity. Baseline physical inactivity was strongly predictive of physical inactivity at 5 years (odds ratio, 3.27; 95% confidence interval, 2.36-4.54; P < .0001). CONCLUSIONS: Gender-related differences were noted in factors associated with and predictive of physical inactivity.

ABSTRACT

BACKGROUND: The Detection of Ischemia in Asymptomatic Diabetics (DIAD) study demonstrated a low 5-year hard cardiac event rate. We hypothesized that a blunted heart rate response (HRR, maximum percent change) to adenosine, a simple marker of cardiac autonomic neuropathy, will identify a cohort at higher cardiac risk. METHODS: In DIAD, 518 participants were randomized to screening adenosine myocardial perfusion imaging (MPI) and had available data. HRR <20% was considered abnormal. The primary endpoint was a composite of nonfatal myocardial infarction and cardiac death. RESULTS: During 4.7 ± 0.9 years of follow-up 15 (3%) participants experienced the primary outcome. Participants with lower HRR experienced more events than those with higher HRR (8%, 3%, 1%, for HRR <20% (n=79), 20-39% (n=182) and ≥ 40% (n=257), respectively, p=0.01). In a Cox proportional regression model that included MPI abnormalities and HRR, both were independently associated with cardiac events (p for model <0.001). HRR <20% was associated with 9-fold increased risk (p=0.007) and moderate/large abnormal MPI was associated with 6-fold increased risk (p=0.004). Participants with both abnormal MPI and HRR (n=8) were at highest risk for cardiac events (38%) whereas those with HRR ≥ 40%, irrespective of MPI abnormalities (n=234), were at extremely low risk (≤1%, log-rank p<0.001). CONCLUSIONS: In DIAD, abnormal HRR to adenosine infusion is an independent predictor of cardiac events. This easily obtained marker of cardiac autonomic neuropathy identifies asymptomatic patients with type 2 diabetes mellitus at increased risk, particularly when associated with abnormal MPI, who may warrant further testing and more aggressive cardiovascular risk factor management.
