作者研究了结扎后4周兔冠脉左室壁结构及左室腔内不同层面压力变化。结果表明:急性心梗后4周左室壁出现不均一性增厚,舒张末容积增加。左室中部收缩期压力由正常时略高于流出道压力转为低于后者,收缩期压力升高的时间顺序由正常时室中略早于流出道变为迟于后者。这种逆转性变化可能是心梗后左室重塑的重要始动及增重因素
The authors studied left ventricular wall structures and pressure changes at different levels in the left ventricle of rabbit coronary arteries 4 weeks after ligation. The results showed that 4 weeks after AMI, heterogeneity of left ventricular wall thickening and end-diastolic volume increased. The systolic pressure in the middle part of the left ventricle decreased from slightly higher than that in the outflow tract at normal to lower than that in the latter. The time sequence of systolic pressure increased slightly earlier than that in the outflow tract. This reversal of change may be important after left ventricular remodeling myocardial infarction and weight gain factors
