Echocardiographic characteristics of cardiac involvement in Systemic lupus erythematosus.

Introduction: Echocardiography is a non invasive tool for the assessment of systemic lupus erythematesus (SLE) involvement .

Aim Of Study: to investigate the cardiac involvement in patients diagnosed with SLE assessed by echocardiography and to study relationship between several factors and cardiac manifestation .

Methods: retrospective study of 76 patients with diagnosis of SLE between 2008 and 2017. All patients were asssesed by echocardiography .Patients were assigned into cardiac abnormalities group and non cardiac abnormmalties and compared to study relations between several factors and cardiac manifestation .

Result: Cardiac involvement was found in echocardiography in 52% of patients (40 patients. Echocardiographic findings showed 12 cases ( 38 %) of pericardial effusion . Valvular abnormalities were observed in 19 cases (48 %), Myocardium was involved in 5 cases ( 12.5 %). there were no cases of myocarditis , High arterial pulmonary hypertension was reported in 4 cases (10%). Men were more vulnerable to cardiac involvement in lupus , there was signifiant relationship between disease duration and cardiac abnormalities (p 0.04 ), age was not associated significantly to echocardiographic abnormalites ,positif antiphospholipid antibodies(aPL+) was observed in higher frequency in cardiac involvement group with p<0.01 and especially in valvular anomalies Conclusion : Echocardiography should be routinely indicated for evaluation of cardiac involvement during SLE. These manifestations are most often moderate and asymptomatic. Pericardial effusion, and valvular involvement were the most frequent abnormalities.
