BACKGROUND Increased attention has been given to pulse pressure (PP) as a potential independent risk factor for cardiovascular disease (CVD). We examined the relationship between the three indices of blood pressure consisting of systolic blood pressure (SBP), diastolic blood pressure (DBP), and PP (= SBP - DBP), respectively, and incident acute coronary(More)
BACKGROUND Statins reduce the risk of coronary heart disease (CHD) in individuals with a history of CHD or risk equivalents. A 10-year CHD risk >20% is considered a risk equivalent but is frequently not detected. Statin use and low-density lipoprotein cholesterol (LDL-C) control were examined among participants with CHD or risk equivalents in the nationwide(More)
BACKGROUND Perceived stress may increase risk for coronary heart disease (CHD) and death, but few studies have examined these relationships longitudinally. We sought to determine the association of perceived stress with incident CHD and all-cause mortality. METHODS AND RESULTS Data were from a prospective study of 24 443 participants without CHD at(More)
BACKGROUND AND OBJECTIVES Calcification of the mitral and aortic valves is common in dialysis patients (CKD-5D). However, the prognostic significance of valvular calcification (VC) in CKD is not well established. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS 144 adult CKD-5D patients underwent bidimensional echocardiography for qualitative assessment of(More)
PURPOSE To compare the characteristics and prognosis of acute myocardial infarctions (AMIs) that were not the primary reason for hospitalization, and thus not primary discharge diagnosis, to AMIs that were the primary reason for hospitalization. METHODS Primary discharge diagnoses for Reasons for Geographic and Racial Differences in Stroke study(More)
BACKGROUND Lipid management is less aggressive in blacks than whites and women than men. PURPOSE To examine whether differences in lipid management for race-sex groups compared to white men are due to factors influencing health services utilization or physician prescribing patterns. METHODS Because coronary heart disease (CHD) risk influences physician(More)
BACKGROUND Blacks have higher coronary heart disease (CHD) mortality compared with whites. However, a previous study suggests that nonfatal CHD risk may be lower for black versus white men. METHODS We compared fatal and nonfatal CHD incidence and CHD case-fatality among blacks and whites in the Atherosclerosis Risk in Communities study (ARIC), the(More)
The association of atrial fibrillation (AF) with the severity and control of hypertension (HTN) remains unclear. We analyzed data from the national biracial cohort of REasons for Geographic And Racial Differences in Stroke study. The AF prevalence ratios were estimated and full multivariable adjustment included demographics, risk factors, medication(More)
PURPOSE It is unclear whether peer coaching is effective in minority populations living with diabetes in hard-to-reach, under-resourced areas such as the rural South. We examined the effect of an innovative peer-coaching intervention plus brief education vs brief education alone on diabetes outcomes. METHODS This was a community-engaged,(More)
CONTEXT It is unknown whether long-standing disparities in incidence of coronary heart disease (CHD) among US blacks and whites persist. OBJECTIVE To examine incident CHD by black and white race and by sex. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of 24,443 participants without CHD at baseline from the Reasons for Geographic and Racial(More)
