肥厚型心肌病常伴有胸痛和运动时ST 段下移,此时是否合并冠脉狭窄是临床诊断较难解决的问题。作者对劳累时伴胸痛的肥厚型心肌病病人,且冠脉造影量有意义冠脉狭窄而冠脉造影正常的肥厚型心肌病病例,用活动平板运动负荷试验行对照研究,评价其对肥厚型心肌病合并冠心病的临床诊断价值。对象和方法伴有胸痛而选择性冠脉造影正常的肥厚型心肌病病例21例为Ⅰ组,冠脉造影为50%以上有意义的狭窄的肥厚型心肌病病例11例为Ⅱ组,其中冠脉75%以上狭窄7例,50～75%冠脉狭窄为4例,冠
Hypertrophic cardiomyopathy often accompanied by chest pain and ST-segment movement down, at this time is the clinical diagnosis of coronary artery stenosis more difficult to solve the problem. The author of patients with chest pain during exertion of hypertrophic cardiomyopathy patients, and coronary angiography coronary stenosis and coronary angiography of normal cases of hypertrophic cardiomyopathy, exercise treadmill exercise test in a controlled study to evaluate its effect on hypertrophic Clinical diagnosis of cardiomyopathy with coronary heart disease. Subjects and Methods 21 cases of hypertrophic cardiomyopathy with chest pain and normal coronary angiography were selected as group Ⅰ, and 11 cases of hypertrophic cardiomyopathy with coronary stenosis of more than 50% 7 cases of coronary artery stenosis of more than 75%, coronary stenosis of coronary artery from 50 to 75%
