According to the echocardiography,enlarged internal diameter of left ventricle was found in 8 patients and short-axis fractional shortening of left ventricle 5% in 3 patients.Six out of the above 8 patients presented with shortening of accerlerating time,decreasing of accerlerating time/right ventricular ejective time value and moving forward of spectral peak in different degrees.All patients were given antianginal drugs such as β-recepter blockers,nitrate preparations and part by angiotensin converting enzyme inhibitor,diuretics and digoxin,The illncss of 29 patients were gradually controlled within one week.Three patients with AD were complicated by acute left heart failure.No obvious changes in FS of left ventricle were found on echocardiography by bed.

测量肺动脉瓣口血流频谱，左心室内径增大的8例中有6例出现不同程度的血流加速时间缩短，血流加速时间/右心室射血时间比值减小，频谱峰值前移。31例均给予β受体阻滞剂、硝酸酯类等抗心绞痛治疗，部分给予血管紧张素转换酶抑制剂、利尿剂和地高辛，其中29例在1周内卧位型心绞痛逐步得到控制。3例卧位型心绞痛发作时合并急性左心衰竭者，在床旁观察超声心动图，发现左心室短轴缩短率无显著变化，给予利尿剂、减轻前后负荷等治疗，急性左心衰竭得以纠正。
