WebIn the normal heart, over the usual working range of left ventricular volume, the relationship between LVEDP and LVEDV is relatively linear (see Fig. 1-5). However, at high ventricular volumes, the curve becomes very steep such that a small increase in volume results in a large increase in pressure. Web其次，大量临床研究也支持这一观点，早在1987年就有学者发现，心梗溶栓患者的左室射血分数是预测预后的有效指标，而近年的valiant研究也发现，左室射血分数（lvef）、左室舒张末期容积（lvedv）及收缩末期容积（lvesv）均是心衰患者死亡或心衰再入院的独立危险因素。
