Importance: Direct oral anticoagulant (DOAC)-associated intracranial hemorrhage (ICH) has high morbidity and mortality. The safety and outcome data of DOAC reversal agents in ICH are limited.

Objective: To evaluate the safety and outcomes of DOAC reversal agents among patients with ICH.

Background: The contribution of arterial endothelial dysfunction (ED) to increased cardiovascular disease (CVD) risk among Blacks is not known.

Hypothesis: We investigated whether peripheral arterial ED explains racial disparity in CVD events.

Methods: Data from the Heart Strategies Concentrating on Risk Evaluation (Heart SCORE) study was used.

Background And Purpose: The longitudinal invariance of the Center for Epidemiologic Studies-Depression (CES-D) scale among middle-aged and older adults is unknown. This study examined the factorial invariance of the CES-D scale in a large cohort of community-based adults longitudinally.

Methods: 1,204 participants completed the 20-item CES-D scale at 4 time points 1 year apart.

Sleep apnea and obesity are strongly associated, and both increase the risk for coronary artery disease. Several cross-sectional studies have reported discrepant results regarding the role obesity plays in the relation between sleep apnea and coronary artery calcium (CAC), a marker of subclinical coronary disease. The aim of the present study was to investigate the association between sleep apnea and the presence of CAC in a community cohort of middle-aged men and women without preexisting cardiovascular disease, stratified by body mass index (<30 vs ≥30 kg/m(2)).

Objectives: Insomnia and sleep apnea frequently co-occur and are independently associated with an increased risk of cardiovascular disease, but little is known about cardiovascular disease risk among individuals with comorbid insomnia and sleep apnea. The current study examined traditional risk factors and a physiologic biomarker of cardiovascular risk in comorbid insomnia and sleep apnea.

Design: Community-based participatory research study.

Background: Treatment guidelines for lipids have become increasingly more aggressive. However, naturally low or therapeutically reduced cholesterol levels may be associated with adverse psychological health symptoms, including depression, aggression, and hostility.

Objective: To examine relationships between low total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol levels and measures of psychosocial status among middle-aged adults.

Purpose: To identify factors associated with attrition in a longitudinal study of cardiovascular prevention.

Methods: Demographic, clinical, and psychosocial variables potentially associated with attrition were investigated in 1841 subjects enrolled in the southwestern Pennsylvania Heart Strategies Concentrating on Risk Evaluation study. Attrition was defined as study withdrawal, loss to follow-up, or missing 50% or more of study visits.

Large epidemiologic studies examining differences in cardiovascular disease (CVD) risk factor profiles between European Americans and African Americans have exclusively used self-identified race (SIR) to classify individuals. Recent genetic epidemiology studies of some CVD risk factors have suggested that biogeographic ancestry (BGA) may be a better predictor of CVD risk than SIR. This hypothesis was investigated in 464 African Americans and 771 European Americans enrolled in the Heart Strategies Concentrating on Risk Evaluation (Heart SCORE) Study in March and April 2010.

Background: Cardiovascular health is a new construct defined by the American Heart Association (AHA) as part of its 2020 Impact Goal definition. The applicability of this construct to community-based populations and the distributions of its components by race and sex have not been reported.

Methods And Results: The AHA construct of cardiovascular health and the AHA ideal health behaviors index and ideal health factors index were evaluated among 1933 participants (mean age 59 years; 44% blacks; 66% women) in the community-based Heart Strategies Concentrating on Risk Evaluation (Heart SCORE) study.

Background: Blood pressure predicts the risk of cardiovascular disease events in a linear, graded manner. Factors associated with significant short-term increases in blood pressure are not well established. We aimed to identify predictors of a significant increase in blood pressure over a 1-year period among nonhypertensive, community-dwelling adults.

Background: Lipoprotein particle levels and size distributions differ by race. As a group, blacks have less coronary artery calcification (CAC) than whites. We evaluated whether racial differences in CAC are explained by differences in lipoprotein levels and particle sizes.
