急性心肌梗死不同梗死部位早期无创心功能检测60例临床分析

The Analysis of Cardiac Function of Different Parts of Acute Infarcted Myocardium of 60 patients,Tested by Noninvasive Way Early

目的用心阻抗法检测急性心肌梗死早期无创心功能参数,对不同梗死部位的心功能异常特点进行对比,结合临床进行分析。方法2007年1-12月住院的急性心肌梗死患者60例,按梗死部位不同分为前壁组30例,下壁组30例,另设健康对照组30例。应用CHMT3001无创心脏血流动力监测仪检测其心功能。结果急性心肌梗死早期（无论是前壁组或下壁组）均出现泵功能下降,舒张功能减退,收缩功能轻度受损,后负荷增加;前负荷无变化。前壁组与下壁组的心功能参数无明显差异。结论通过无创心功能检测发现了急性心肌梗死早期心功能异常的特点;前壁组病死率（多死于泵衰竭）高于下壁组,但前壁组早期心功能异常与下壁组无明显差异;对前壁心梗早期应采取更积极的恢复心肌再灌注的措施象PCI等,以减少病死率。

Objective To detect parameters of early nonivasive cardiac function of patients with acute myocardia infarction by cardiac impedance. The dysfunction characteristics were compared with different infarcted parts and were analysised by combination with clinic analysis. Methods Sixty hospitalized patients with acute myocardial infarction from Jaurary to December in 2007 were divided into anterior wall group（ include 30 cases ） and inferror wall group （ include 30 cases） by different infarcted parts. Another healthy control group was founded. The cardiac function of all patients detected by CHM T3001 non-invasive hemedynamic device. Results The change of patients with acute myocardial infarction （ both anterior or inferior group） as following： decline in pump function, diastolic dysfunction, systolic function impaired mildly, afterload increased, preload unchanged. No difference was found between the anterior wall and the inferior wall group. Conclusion The characteristics of early cardiac dysfunction was found by noninvasive detection in acute myocardial infarction; the mortality rate of anterior Group （most died from pump failure） higher than that of inferior group, but the significant difference of early cardiac dysfunction was not found between the two groups. In order to reduce mortality, more active methods （as PCI）should be take to recover myocardial reperfusion, early should take a more active recovery myocardial reperfusion as PCI measures so as to reduce the mortality rate.
