Abstract
One hundred consecutive female patients with active systemic lupus erythe matosus (SLE) were studied from the cardiovascular point of view by means of non invasive methods. Seventy percent of the cases presented some type of car diovascular anomaly. Seventy four percent of the resting electrocardiograms were abnormal as well as 72% of the M mode echocardiograms and 55% of the cardiac X ray series. The most frequent observed complications were: pericar ditis and or pericardial effusion (39%), arterial hypertension (22%), ischemic heart disease (16%), myocarditis (14%), congestive heart failure (10%), pulmo nary hypertension (9%), valvular heart disease (9%), pleural effusion (7%) and cerebro vascular accident (3%). We analized each one of these complications and found of special interest the high incidence of ischemic heart disease which is more frequent than has been hitherto reported. Ischemic heart disease was observed in two types of patients: a) Those with long term steroid therapy. In these, the mechanism seems to be an atherosclerotic disease probably induced by the chronic use of steroids. The management of these cases do not differ from other types of coronary heart disease due to atherosclerosis. b) Those with frank episodes of vasculitis in whom the basic mechanism is an inflammatory process of the coronary arteries and its treatment is fundamentally that of the vasculitis. We consider necessary to study routinely all patients with SLE through non invasive cardiological methods.
