摘要 目的随着GMPI在国内的不断推广,临床医生需要了解GMPI与M型超声心动图在筛查异常LVEF方面的一致性。方法从入住该院心血管内科的住院患者中连续选取同时行静息GMPI与M型超声心动图的患者129例。LVEF<50%认为异常,LVEF≥50%认为正常,采用kappa检验比较两种检测手段筛查异常LVEF的一致性。随后将患者分为灌注缺损组(SRS>3)与灌注正常组(SRS≤3),分别比较两种检测手段筛查异常LVEF的一致性。结果两种检测手段筛查异常LVEF的一致性较好,kappa值为(0.819±0.057)。无灌注缺损时(76例),两种检测手段一致性进一步提高,kappa值为(0.941±0.059)。有灌注缺损时(43例),两种检测手段一致性欠佳,kappa值为(0.63±0.113)。结论 GMPI与M型超声心动图筛查异常LVEF有较好的一致性,两种检测手段都可以很好的应用于异常LVEF的筛查。灌注缺损时一致性降低。
