INTRODUCTION/OBJECTIVES: Patients with rheumatoid arthritis (RA) are at increased risk for congestive heart failure (CHF) and left ventricular diastolic dysfunction (LVDD), as compared to the general population. High disease activity is to be associated with higher incidence of cardiovascular disease (CVD), CHF, and mortality in RA patients. LVDD is not anticipated in RA patients without CVD symptoms and may be underdiagnosed especially in those with low disease activity.
METHOD: The study group consisted of 70 RA patients (54 women, 16 men) with no CVD and 33 healthy controls, of comparable age. All RA patients had low disease activity (DAS28 ≤ 3.2) from 2 to 7 years. Laboratory and imaging assessments included metabolic, RA-related, and cardiovascular parameters. Echocardiographic and Doppler studies were conducted in patients and controls with assessment of ejection fraction (EF) and diastolic dysfunction (assessed as E/A ratio).
RESULTS: The mean E/A ratio did not differ significantly between RA patients and healthy controls (1.08 (0.28) vs 0.99 (0.21), NS); comparable numbers of patients and controls had abnormal E/A (< 1.0) (26 (37.1%) vs 10 (30.3%), NS). Patients with decreased E/A were significantly older and had higher disease duration, activity, and presence of bone erosions than their RA counterparts with normal E/A. The mean EF was not significantly different in patients and controls.
CONCLUSIONS: The prevalence of DD as expressed by E/A ratio in RA patients with continued low disease activity was not different from that of controls. Higher disease duration and severity may predispose to DD occurrence in patients with preserved EF.
