[Cardiac manifestations of polymyositis. Apropos of 2 Senegalese cases].
BACKGROUND
Polymyositis cardiac involvement varies between 37% and 70%. EXEGENESIS: The authors report two cases of polymyositis with myocardial involvement observed in Senegal; the first case is a cardiac failure revealing an acute polymyositis occurring in a 44-year-old woman; the second case is a 34-year-old woman who had polymyositis with tachycardia and dyspnea: in the two cases echocardiography showed a left ventricular concentric hypertrophy with preserved systolic function and altered diastolic function; clinical and echocardiographic resolution were obtained by corticosteroid medication.


CONCLUSIONS
Myocardial localization is the most common polymyositis cardiac involvement; clinical symptomatology is rare (3.3% to 6%). sometimes revealing polymyositis; electrocardiographic abnormalities are found in 18% to 81% cases and echographic abnormality in 42% cases; cardiac involvement is of bad prognosis.
