Sixteen cases of polymyositis (PM) were treated at the Central Hospital, Jyväskylä. Features of cardiac involvement were observed in 11 cases (69%). The heart diseases which developed or worsened after the onset of PM were grouped as follows: (1) Sole disturbance of conduction--one case, (2) congestive heart failure--four cases, (3) coronary heart disease with or without congestive heart failure--six cases. Three patients suffered an acute myocardial infarction. Electrocardiography revealed arrhythmias in eight cases and disturbances of conduction in three. In one patient complete atrioventricular block and congestive heart failure necesssitated installation of an intracardiac pacemaker. In four patients congestive heart failure progressed to death. In two autopsied cases changes suggestive of PM were found in the heart muscle. Involvement of the heart in PM was prognostically a bad sign.
于于韦斯屈莱中心医院对16例多发性肌炎（PM）患者进行了治疗。11例（69%）出现心脏受累特征。在PM发病后出现或加重的心脏病分类如下：（1）单纯传导障碍——1例；（2）充血性心力衰竭——4例；（3）伴有或不伴有充血性心力衰竭的冠心病——6例。3例患者发生急性心肌梗死。心电图显示8例心律失常，3例传导障碍。1例患者因完全性房室传导阻滞和充血性心力衰竭而需要安装心内起搏器。4例患者充血性心力衰竭进展至死亡。在2例尸检病例中，心肌发现提示PM的改变。PM患者心脏受累在预后方面是一个不良征象。
