摘要

目的:探讨小剂量多巴酚丁胺负荷超声心动图（Low-dose dobutamine stress echocardiography

LDDSE）在急性心肌梗死预后中的评价作用。方法:对2004年符合标准的我院心内科47例急性心肌梗死患者病情稳定后进行LDDSE检查

并进行为期5年的系统随访。结果:LDDSE试验过程中无患者出现严重并发症

而整体心功能增强的趋势

表现为LVED缩小、LVEF增高（P<0.05）和WMSI的减少（P<0.05）。5年随访内共失访3例

随访率93.6%。23例死亡

其1、3、5年生存率分别为86.5%、63.2%和42.7%。而超声指标中WMSI对5年生存预后鉴别力最佳

AUC为0.717

95%CI为0.614～0.820（P=0.0001）。而发病时WMSI也是影响其的预后独立危险因素（P<0.05）。结论:小剂量多巴酚丁胺负荷超声心动图的室壁运动检查对急性心肌梗死患者5年生存预后有较好鉴别力

WMSI是影响其预后的独立危险因素。

Abstract

Objective:To investigate the prognostic value for low-dose dobutamine stress echocardiography(LDDSE)in patients with acute myocardial infarction.Methods:In 2004

47 patients with acute myocardial infarction in stable condition were given LDDSE checks in our hospital

and conduct follow-up period of 5 years.Results:No patients with serious complications in LDDSE

the overall cardiac function improved

expressed as LVED decreased

LVEF increased(P <0.05)and WMSI reduced(P <0.05).A total of 3 patients lost in 5-year follow-up

the follow-up rate was 93.6%

and 23 patients dead

the 1

5 year survival rates were 86.5%

63.2% and 42.7%.The WMSI discernment best for the five-year survival prognosis

AUC = 0.717

95% CI 0.614-0.820(P=0.000 1).The WMSI was also an independent risk factor for acute myocardial infarction(P<0.05).Conclusion:Low-dose dobutamine stress echocardiography have good discernment for 5-year survival prognosis of acute myocardial infarction

and the WMSI was the independent prognostic risk factors.
