Cardiovascular Risk Factors and Echocardiographic Findings in a Predominantly Black Population with Rheumatoid Arthritis and Heart Failure.

Abstract

Among White rheumatoid arthritis (RA) cohorts, heart failure with preserved ejection fraction (HFpEF) is the most prevalent type of heart failure (HF). We aimed to assess the type of HF affecting Black RA patients. 64 patients with RA-HF were compared to age-, sex-, and race-matched RA patients without HF. Left ventricular ejection fraction (LVEF), wall motion abnormalities, left ventricle (LV) mass, and wall thickness were reviewed. 87.3% were Black, 84.4% were women, with a mean age of 69.6 ± 1.38 (± SEM) and BMI (kg/m 2) 29.6 ± 1.07. RA-HF patients had higher rates of hypertension (HTN), chronic kidney disease, and atrial fibrillation. 66.7% had ≥3 cardiovascular risk factors compared to RA patients without HF. 2D-echocardiograms of RA-HF revealed that 62.3% had LVEF ≥50%, 37% had diastolic dysfunction, and 43.1% had wall motion abnormalities. LV mass and relative wall thickness measurements indicated LV eccentric remodeling. The odds ratio for HF was 4.7 (1.5-14.53 CI), p<0.01, among RA-HTN group and 3.5 (1.091-11.7 CI) p<0.01 among smokers. In our predominantly Black RA-HF patients, HFpEF was the most common type of HF. HTN was associated with the highest OR for HF. Eccentric hypertrophic remodeling, a known poor prognostic indicator for cardiovascular events, was found. Further studies are required to confirm our findings.
