作者观察了30例肥厚型心肌病、21例充血型心肌病的血液动力学与组织学改变,也研究了实验性柯萨奇B病毒心肌炎以探讨它与心肌病的关系。左心室收缩功能通过心导管检查,发现肥厚型心肌病的搏血指数与心脏指数正常,而充血型心肌病则减低。通过选择性左心室电影造影观察到肥厚型心肌病的舒张末期及收缩末期容积正常或缩小(舒张末期容积平均70±17毫升/平方米),而充血型心肌病则增大(舒张末期容积平均151±28毫升/平方米)。肥厚型心肌病的喷血分数平均为74±8％,属正常或增高(正常值为67±8％);而充血型心肌病平均为41±19％,低于正常,两组差别显著。
The authors observed hemodynamic and histological changes in 30 patients with hypertrophic cardiomyopathy and 21 patients with congestive cardiomyopathy and also investigated experimental coxsackievirus B myocarditis to investigate its association with cardiomyopathy. Left ventricular systolic function by cardiac catheterization found that stroke and hypertrophic cardiomyopathy Cardiac index normal heart index, while decreased congestive cardiomyopathy. Through selective left ventricular angiography, the end-diastolic and end-systolic volumes of hypertrophic cardiomyopathy were normal or contractile (end-diastolic volume average 70 ± 17 ml / m 2), while congestive cardiomyopathy increased (mean diastolic volume 151 ± 28 ml / m 2). Hypertrophic cardiomyopathy spurt score averaged 74 ± 8%, is normal or increased (normal value of 67 ± 8%); and congestive cardiomyopathy average of 41 ± 19%, lower than normal, the difference was significant between the two groups.
