在多肌炎中,心脏受累虽早巳发现,但认为少见。为了肯定其心脏受累的程度,作者在21例多肌炎患者用非侵入性心脏诊断技术作了研究。这些患者无急性病毒性心肌炎或肉样瘤病,均未用洋地黄、利尿剂或其他可加强心脏功能的药物。患者均进行了心电图、心音图和超声心动图检查。在超声心动图中测量了二尖瓣斜率(MVS)、在室舒张末期内径(Dd)、左室收缩末期内径(Ds)、在室后壁厚度(LVWT)、左室周边缩短速率(Vcf)和缩短分数(FS)。此外,在15例无心脏疾患者也作了超声心动图检查,作为对照。
In polymyositis, heart involvement has been found, but is considered rare. To confirm the extent of heart involvement, the authors studied noninvasive cardiac diagnosis in 21 patients with polymyositis. None of these patients had acute viral myocarditis or sarcoidosis without using digitalis, diuretics, or other medications that enhance heart function. All patients underwent ECG, phonocardiogram and echocardiography. The changes of mitral valve slope (MVS), end-diastolic diameter (Dd), end-systolic diameter (Ds), posterior wall thickness (LVWT), and left ventricle shortening (Vcf) were measured in echocardiography. And fractional shortening (FS). In addition, echocardiography was also performed in 15 patients without heart disease as a control.
