用M型超声心动图对51例AMI患者左心功能20项指标测定结果表明,病人组与同龄正常人之间有17项指标差异非常显著,有心衰或死亡者,均有多项指标异常。其中9项指标对区分是否心衰比较敏感,2～3项指标同时异常者反映存在心衰及预后差。作者认为M型超声心动图综合指标有助于评价AMI 病人的心功能和近期预后。
M-mode echocardiography in 51 cases of AMI patients with left ventricular function measured 20 indicators showed that the patient group and normal subjects of the same age there are 17 indicators of significant differences, with heart failure or death, there are a number of indicators of abnormalities . Nine indicators of which are sensitive to distinguish between heart failure, 2 to 3 indicators of abnormalities reflect the existence of heart failure and poor prognosis. The authors believe that M-type echocardiography integrated indicators help to evaluate the AMI patients with cardiac function and short-term prognosis.
