Records from 18 subjects with angiographic idiopathic mitral valve prolapse, 28 subjects with merely exaggerated posterior mitral leaflet systolic bulging, and 100 subjects with normal hemodynamic and angiographic findings were compared with regard to age, sex, height, weight, ponderal index (height/3 square root weight), auscultatory and echocardiographic abnormalities. Chest x-ray films available for subjects with mitral valve prolapse were reviewed. The ponderal index of subjects with mitral valve prolapse (13.1 +/- 0.8) differed from that of subjects with merely exaggerated posterior mitral leaflet systolic bulging (12.6 +/- 0.7) (P less than 0.02) and from that of subjects without angiographic abnormality (12.3 +/- 0.8) (P less than 0.001). The three groups differed in ponderal index when equated statistically for age, height, weight, and sex (P less than 0.001). Among mitral valve prolapse patients, an asthenic habitus occurred independent of the presence of thoracic skeletal abnormalities.
对18例血管造影显示特发性二尖瓣脱垂患者、28例仅有二尖瓣后叶收缩期膨出增大的患者以及100例血流动力学和血管造影检查结果正常的患者的年龄、性别、身高、体重、体重指数（身高/体重的立方根）、听诊及超声心动图异常情况进行了比较。对二尖瓣脱垂患者的胸部X光片进行了复查。二尖瓣脱垂患者的体重指数（13.1±0.8）与仅有二尖瓣后叶收缩期膨出增大的患者（12.6±0.7）不同（P<0.02），与无血管造影异常的患者（12.3±0.8）也不同（P<0.001）。当对年龄、身高、体重和性别进行统计学校正后，三组患者的体重指数仍存在差异（P<0.001）。在二尖瓣脱垂患者中，无力型体质的出现与胸廓骨骼异常无关。
