用彩色多普勒超声对91例急性首次心梗3天内患者的二尖瓣返流进行了测定,并对患者进行了平均22.1月的随访.发现伴二尖瓣返流患者占34%,这些患者女性多,年龄大,梗塞面积大,非Q波梗塞多,Ptfv_1小和房性心律失常多,而且使用强心剂及利尿剂患者多,住院期心功能差,心脏事件多和观察期死亡率高,但二尖瓣返流不是预测死亡的独立因素.表明心梗急性期彩色多普勒测定的二尖瓣返流可能只是反映数种危险因素的一个综合性的信息,而非独立于其它因素之外的预后指标.
Mitral regurgitation in 91 patients with acute first myocardial infarction within 3 days was measured by color Doppler ultrasound and was followed up for a mean of 22.1 months. 34% of patients with mitral regurgitation were found More patients were female, older, larger infarct size, more non-Q infarcts, more small Ptfv_1 and atrial arrhythmias, more cardiac and diuretic patients, poor cardiac function during hospitalization, more cardiac events and higher mortality during observation period , But mitral regurgitation is not an independent predictor of mortality, suggesting that mitral regurgitation in the acute phase of myocardial infarction may only be a comprehensive piece of information that reflects several risk factors, rather than being independent of other factors Out of the prognostic indicators.
