[Cardiovascular manifestations of dermatopolymyositis].

The cardiovascular symptoms of six patients suffering from polymyositis were considered with reference to Pearson's classification. Transmural ischaemia type ventricular repolarisation anomalies were noted in two patients while clinica signis of cardiopathy were not present. A progressive disturbance in intraventricular condition was noted in one case. In another patient signs of atrial tachycardial type paroxysms with a variable A-V block were noted. Dilatative cardiomyopathy with progressive congestive decompensation and hyperkinetic ventricular arrhythmias were noted in two patients. These conditions responded partially to medical treatment. ECGraphic signs of pseudonecrosis and clinicoechographic signs of mitral valve prolapse were noted in another patient. These signs were not accompanied by either coronary or valvular clinical involvement equivalents.
