从因胸痛、冠心病(CAD)的危险因素作心导管和冠状动脉造影检查的单纯二尖瓣狭窄82例中检出21例,合并冠状动脉病变。此21例中,男14例、女7例,平均年龄分别为59±5岁和58±18岁;具心纹痛9例、不典型胸痛5例;其中16例冠状动脉呈中～重度病变(至少一支冠脉直径狭窄超过50～70％)。另心导管血液动力学指标(包括二尖瓣区特征性压力曲线,心排量,肺动脉压,肺血管阻力,左室舒张末期压,左室喷血分数等)均不能鉴别有CAD。
Twenty-one patients with mitral stenosis underwent cardiac catheterization and coronary angiography in 21 patients with coronary artery disease were selected from 82 patients with chest pain and coronary heart disease (CAD) risk factors. The 21 patients, 14 males and 7 females, the average age were 59 ± 5 years and 58 ± 18 years; with heart-shaped pain in 9 cases, 5 cases of atypical chest pain; of which 16 cases of coronary artery was moderate to severe disease (At least one coronary stenosis more than 50 to 70%). The other cardiac catheterization hemodynamic parameters (including characteristic mitral pressure curve, cardiac output, pulmonary artery pressure, pulmonary vascular resistance, left ventricular end-diastolic pressure, left ventricular ejection fraction, etc.) can not be identified with CAD.
