POLYMYOSITIS CARDIAC INVOLVEMENT - 2 SENE GALESE CASE-REPORTS

Introduction. - Polymyositis cardiac involvement varies between 37% an d 70%. Exegenesis. - The authors report Mo cases of polymyositis with myocardial involvement observed in Senegal; the first case is a cardia c failure revealing an acute polymyositis occurring in a 44-year-old w oman; the second care is a 34-year-old woman who had polymyositis with tachycardia and dyspnea; in the two cases echocardiography showed a l eft ventricular concentric hypertrophy with preserved systolic functio n and alterated diastolic function; clinical and echocardiographic res olution were obtained by corticosteroid medication. Conclusion, - Myoc ardial localization is the most common polymyositis cardiac involvemen t; clinical symptomatology is rare (3.3% to 6%), sometimes revealing p olymyositis; electrocardiographic abnormalities are found in 18% to 81 % cares and echographic abnormality in 42% cares; cardiac involvement is of bad prognosis.
