BACKGROUND:Black men in the United States have higher hypertension (HTN) prevalence than other groups, largely due to adverse social determinants of health, including poor healthcare access. The Community-to-Clinic Linkage Implementation Program (CLIP) is effective for HTN screening in Black-owned barbershops. However, its effect on HTN prevention among Black men is untested. Here, we describe the rationale and study protocol for the development and testing of a barbershop facilitation (BF) strategy, with trained Community Health Workers, to implement and scale CLIP for HTN prevention in Black men. METHODS:The study is part of the American Heart Association (AHA)-funded RESTORE (Addressing Social Determinants to Prevent Hypertension) Health Equity Research Network. The study is tri-phasic: (i) pre-implementation-qualitative examination of factors affecting adoption of CLIP and development of BF strategy, (ii) implementation-cluster randomized control trial to test the effectiveness of CLIP with and without BF. We will partner with 20 barbershops and enroll 420 Black men with elevated blood pressure (BP)/Stage 1 HTN (2017 ACC/AHA HTN guidelines). Outcomes include reduction in BP, rate of CLIP adoption and linkage to care, and incidence of Stage 2 HTN. The study time frame is 12 months, (iii) post-implementation-we will evaluate program sustainability (6 months post-trial conclusion) and cost-effectiveness (up to 10 years). CONCLUSIONS:This study harnesses community-based resources to address HTN prevention in Black men, who are more adversely impacted by HTN than other groups. It has major policy relevance for health departments and other stakeholders to address HTN prevention in Black communities. CLINICALTRIALS.GOV IDENTIFIER/BACKGROUND:NCT05447962.

AIMS/OBJECTIVE:Cardiovascular disease (CVD) is a leading cause of increased disability from work worldwide. Chronic stress including work-related stressors influences cardiovascular health. The purpose of this study was to assess stress levels amongst workers with CVD. The specific aims were to: (i) evaluate associations of the biological marker-hair cortisol concentration (HCC) with perceived stress and (ii) examine associations of HCC and perceived stress with sociodemographic factors and work-related factors. METHODS AND RESULTS/RESULTS:This cross-sectional descriptive study (n = 75) of employed adults (≥ 21 age) with CVD assessed perceived stress, work-related factors including workplace support, job control, job strain, and work-life balance using valid and reliable instruments. Hair cortisol concentration was measured using collected hair samples. Data analyses included descriptive statistics, correlational, and ANOVA analysis. The sample was 64% female; 80% are White, 8% African American, 4% Asian, and 8% Hispanic; mean 12 years with CVD diagnosis. Hair cortisol concentration was significantly correlated with workplace support by co-workers (r = -0.328, P = 0.012), supervisors (r = -0.260, P = 0.05), and skill discretion (-0.297, r = 0.047) but not perceived stress. Those with better work-life balance had lower HCC (F = 3.077, P = 0.054) and lower perceived stress (F = 10.320, P < 0.01). CONCLUSIONS:Although this sample of working adults with CVD reported high levels of perceived stress; only work-related factors were significantly associated with HCC. These results suggest that there are work-related stressors that cut across jobs and workplaces that may contribute to chronic stress in working adults. Healthcare providers across clinical and occupational settings have an important role in addressing work-related stress in working adults with CVD.

BACKGROUND:Hypertrophic cardiomyopathy (HCM) is a common and clinically heterogeneous inherited cardiac disease. Quality of life (QOL) and physical functioning are important clinically but are underexplored in diverse populations with HCM. OBJECTIVES/OBJECTIVE:To examine predictors for and compare QOL and physical functioning in Black and White adults with HCM. METHODS:We analyzed a sub-sample from a longitudinal prospective study on HCM. Eligibility criteria included self-identified Black and White adults (≥18 years) with clinical HCM. QOL was measured with the Minnesota Living with Heart Failure Questionnaire (MLWHF);physical functioning included age-adjusted exercise capacity and NYHA class. Covariates included HCM structural characteristics and common comorbidities. We analyzed data from 434 individuals, 57 (13.1%) of whom self-identified as Black/African American. RESULTS:In this sample, the Black cohort had higher MLWHF scores, 31.2 (27.2) v. 23.9 (22.1), p=0.042, signifying worse QOL, but there were no intergroup differences when QOL was dichotomized. Mean metabolic equivalents (METs) on symptom-limited stress testing were similar, though the Black cohort was younger, 54.6 (13.4) v.62.5 (14.8) years, p=0.001. No one from the Black cohort achieved an "excellent-for-age" exercise capacity, and 64.1% had a "below-average-for-age" exercise capacity vs 47% in the White cohort, though this was not statistically significant, p=0.058. There was no difference between groups in advanced NYHA class. Female gender was associated with worse QOL and physical functioning irrespective of covariates. CONCLUSIONS:This study is a starting point that underscores the need for a more comprehensive examination of well-being and physical functioning in Black populations with HCM.

Background There is limited research on hypertrophic cardiomyopathy (HCM), which is the most common inherited cardiac disorder, in diverse populations, including Black individuals. Current literature lacks comprehensive data on HCM disease expression, comorbidities, and outcomes in this historically disadvantaged group. The purpose of this study was to examine structural HCM characteristics, comorbidities, and outcomes in a Black and White cohort with HCM. Methods and Results The study was a subgroup analysis from a longitudinal, prospective study on HCM, with supplemental chart review. The sample included adults (≥18 years) with a clinical diagnosis of HCM, who self-identified as Black/African American or White. The study sample comprised 434 individuals; 57 (13.1%) were Black, and 180 (41.5%) were women. Black patients were younger than White patients, 54.6 (13.4) versus 62.5 (14.8) years, P=0.001. Black patients were more likely to have sub-basal and diffuse hypertrophy, 22 (38.6%) versus 56 (14.9%), P<0.001, 6 (10.5%) versus 15 (4%), P=0.017, mid-LV obstruction, 7 (12.3%) versus 21 (5.5%), P=0.025, and cardiac fibrosis ≥15%, 10 (22.2%) versus 19 (8.8%), P=0.009, than White patients. Black patients were more likely to experience appropriate implantable cardioverter defibrillator interventions, 5 (38.5) versus 5 (6.8), P<0.001 and were more likely to have ≥2 sudden death risk factors. Comorbidities were largely similar between groups, though more Black participants had Class II obesity, 12 (21.8) versus 30 (8.1), P<0.001. Both groups had similar rates of genetic testing usage. Conclusions This study underscores the need for continued research of HCM in Black populations, including tailored approaches to diagnosis and precise evaluation of cardiac anatomy.

BACKGROUND:Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiac disorder globally, affecting 0.2% to 0.5% of individuals. Existing clinical HCM guidelines do not address diverse populations, specifically minority groups who often experience health disparities. OBJECTIVE:The aim of this study was to describe the state of the science of HCM in black populations. METHODS:This integrated review guided by Whittemore and Knafl's methodology included literature search of multiple databases, data evaluation, and analysis. Publications between 2000 and 2020 were included if they addressed HCM cardiac anatomic manifestations, disease course, symptoms, quality of life, or outcomes in black populations. RESULTS:Six articles met the inclusion criteria. Overall, blacks are underrepresented in HCM research. Certain HCM structural phenotypes are more commonly exhibited in blacks, and physiology drives HCM treatment. Sudden death events and all-cause mortality do not differ between blacks and whites with HCM. Fewer blacks with HCM undergo genetic testing than whites with HCM. The lack of diversity in general genomic databases has resulted in reclassification of several genetic variants identified as more common in blacks. CONCLUSIONS:Blacks are underrepresented in HCM research, even those focused on elucidating HCM manifestations, disease course, and outcomes in black populations. This may be due in part to HCM research that is largely generated from specialty centers that can require patients to navigate complex healthcare systems to reach expert HCM care. Longitudinal studies with large samples of blacks with HCM are necessary to elucidate how HCM affects this population.

Background: Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiac disorder, affecting between 0.2% to 0.5% of the US population. Clinical HCM guidelines do not address diverse populations and there are gaps in the existing literature on Blacks with HCM, a traditionally underserved group. Objective: The purpose of this dissertation was to compare a Black and White cohort with HCM and describe HCM genotype and phenotype, symptom experience, including quality of life, functional capacity and provider assigned functional class (NYHA class), and outcomes differences between groups; to examine the relationship between HCM phenotype, comorbidities, and outcomes; to examine the relationship between functional capacity, HCM structural phenotype, outcomes and co-morbidities.Methods: Secondary analysis of an existing HCM dataset. Results: Blacks comprised 13% of the study sample of 434. Follow - up was a mean 2.2(SD 1.2) years. Both groups had similar magnitude of left ventricular hypertrophy but significant differences in distribution of hypertrophy. Blacks had more cardiac fibrosis. Both groups had similar number of co-morbid conditions, and obesity and hypertension were prevalent across groups. There was overall low mortality in both groups, though Blacks had more aborted sudden death events. While Blacks and Whites had similar functional class and quality of life scores, Blacks had a lower functional capacity. There was no significant association between race, HCM phenotype, symptom experience, and outcomes. Conclusions: Blacks were underrepresented in this sample, consistent with the existing HCM literature. Research with larger samples of Blacks with HCM, especially those who get HCM care in the community, is necessary to allow generalizability of results and to elucidate targets for intervention to reduce health disparities.
