摘要 目的评价超声心动图(UCG)与导管法左室造影(LVG)检测左心室功能的相关性与一致性。方法87例临床诊断冠心病的患者同时行UCG及LVG检查,分别测定左室射血分数(LVEF)并检测左室节段性室壁运动障碍。结果两种方法测定的LVEF值相关性良好(r=0.849,P<0.0001);UCG所测定的LVEF值均值为0.488±0.160,而LVG测定值为0.492±0.188,两者差异无显著性(P=0.8446)。UCG检测左室节段运动异常的总体敏感性和特异性分别达80.4%与75%,阳性预测值与阴性预测值分别达82.0%,73.0%。在LVEF<55%组敏感性和特异性分别达92.3%与100%,阳性与阴性预测值分别为100%与50.0%。结论两种方法测定的LVEF值具有较高的相关性与一致性。UCG检测节段性室壁运动异常有较高的准确性,在冠心病患者左室功能的诊断方面,可作为传统的导管法左室造影一种替代的无创性检查方法。
