Asymptomatic Cardiac Manifestations in Rheumatoid Arthritis in Conakry (Guinea)

Abstract

Introduction: Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatic disease. It is a systemic disease with extra-articular manifestations that can be life-threatening. In sub-Saharan Africa, there is little published information on cardiovascular manifestations in RA. Objective: The objective is to determine the asymptomatic cardiac manifestations during rheumatoid arthritis in Conakry. Patients and Methods: This was a cross-sectional study lasting 6 months from January 1, 2020 to June 30, 2020 in the rheumatology and cardiology departments of the Ignace Deen National Hospital. Patients with RA diagnosed according to the 2010 ACR/EULAR criteria, asymptomatic at the cardiovascular level, which had an ECG and echocardiography, were included in the study. Left ventricular diastolic dysfunction was considered in any patient with an E/A ratio 1, an E/E’ ratio > 10, and an LVEF = 50%, assessed by the Simpson biplane method and classified according to Redfield. Epidemiological, clinical and paraclinical data were analyzed using SPSS statistics 21.0 software. Results: Seventeen cases of rheumatoid arthritis (5.9%) were collected. There was a predominance of women with 14 cases (82.4%). The mean age of patients was 48.2 ± 11.9 years. The average duration of RA was 7.2 ± 4.2 years. Cardiovascular risk factors were dominated by overweight and obesity (58.8%) and sedentary lifestyle (35.3%). RA was predominantly high activity (DAS 28 ≥ 5.1) in 82.4% of patients. Anti-CCP antibodies were positive in 76.9% of cases. Fourteen patients (82.4%) had abnormal cardiac results. The electrocardiogram showed left atrial hypertrophy in 29.4% of cases, left ventricular hypertrophy (11.8%) and ventricular extrasystole (11.8%). The cardiac Doppler scan showed diastolic dysfunction of the left ventricle (47.1%) and moderate pericardial effusion in 11.8% of cases. Conclusion: The study found asymptomatic cardiac manifestations of rheumatoid arthritis. They were dominated by ventricular hypertrophy on electrocardiogram and left ventricular diastolic dysfunction on cardiac Doppler ultrasound. Systematic examination of patients with RA is necessary to detect them early and avoid complications.
