急性心肌梗死患者二尖瓣返流的预后意义

目的：探讨急性心肌梗死（AMI）患者二尖瓣返流（MR）的预后意义。方法：对142例AMI患者住院早期（7天内）行超声心动图检查，以彩色多普勒定量测定其MR。并对MR组及无MR组的临床资料、超声心动图指标及预后进行对比分析。结果：90例无MR（63．38％），轻度MR43例（30．28％），中、重度MR9例（6．34％）。MR组较无MR组患者年龄更大、既往心肌梗死发病率及高血压发病率更高（P＜0．05）。MR返流组脉冲多普勒E峰、E／A显著高于无MR组（P均＜0．05）。MR组30天及1年病死率均显著高于无MR组（P均＜0．05）。结论：超声心动图证实的MR对AMI患者的预后具有预测价值。

Prognostic significance of mitral regurgitation in patients with acute myocardial infarction

Objective To evaluate the prognostic significance of mitral regurgitation (MR) in the patients with acute myocardial infarction (AMI).Methods Echocardiographic examination was conducted in 142 AMI patients within 7 days during admission and color Doppler was used to measure MR.The clinical data,echocardiogram indexes and prognosis in the patients with MR or with no MR were compared and analyzed.Results 90 patients (63.38%) had no MR,43(30.28%) had slight MR and 9(6.34%) had moderate or severe MR.The patients with MR were elder and had a history of higher incidence of myocardial infarction and hypertension than the patients without MR (P<0.05).The E wave and E/A ratio detected by pulse Doppler in the patients with MR were higher than those in the patients without MR (P<0.05).30 day and 1 year mortality rates of the patients with MR were higher than those with MR (P<0.05).Conclusion MR detected by echocardiogram has prognostic value in the patients with AMI.
