Abstract 14831: Racial Disparities and Modifiable Cardiovascular Risk Factors in Black Patients With Familial Hypercholesterolemia

Abstract

Introduction: Black men and women are at higher risk for atherosclerotic cardiovascular disease (ASCVD) and when diagnosed, have greater morbidity and mortality as compared to individuals from European ancestry (EA). In patients with familial hypercholesterolemia (FH), it remains unknown whether Black patients have similarly increased risk for ASCVD. Hypothesis: To characterize the prevalence of ASCVD and to determine the strongest predictors of ASCVD in Black FH patients compared to EAs. Methods: The prevalence of ASCVD in 173 Black adult patients with FH followed in US-based lipid clinics was assessed retrospectively through a multicenter. A multivariate logistic regression model was used to determine the strongest predictors of ASCVD. Covariates included age, sex, diabetes mellitus, hypertension, and current smoking. ASCVD was defined as coronary, peripheral, and cerebrovascular events including angina, myocardial infarction, coronary angioplasty, peripheral arterial surgery, claudication, peripheral angioplasty, transient ischemic attack, stroke, and carotid endarterectomy. Results: Baseline characteristics of the 173 Black adult patients compared to EAs are shown in table 1. Black patients with FH were more likely to have higher BMI, hypertension, diabetes and to be current smokers. The prevalence of ASCVD in Black patients with FH was 38% compared to 30% in EAs, an absolute difference of 8% (p=0.047). The strongest predictors of ASCVD in Black patients with FH were hypertension and current smoking (table 2). Conclusions: Black patients with FH have a significantly higher prevalence of ASCVD when compared to EAs with FH. The strongest predictors of ASCVD in Black patients with FH were hypertension and current smoking. Aggressive primary prevention strategies specifically focused on the management of hypertension and smoking cessation should be tested for impact on the cardiovascular risk profile of Black patients with FH.
