摘要
目的：探讨急性心肌梗塞（ＡＭＩ）后血清心肌肌钙蛋白Ｔ（ｃＴｎＴ）峰值与心功能、左室射血分数（ＬＶＥＦ）的关系。方法：分别测定了２４例急性前壁心肌梗塞患者的ｃＴｎＴ、心功能、左室射血分数（ＬＶＥＦ）、左室舒张末期容积（ＥＤＶ）、左室收缩末期容积（ＥＳＶ）。结果：所有前壁ＡＭＩ患者的ｃＴｎＴ峰值与心功能成等级相关，与ＬＶＥＦ成负相关，与ＥＤＶ．ＥＳＶ成正相关；随访６个月，３例死于心力衰竭的病人ｃＴｎＴ峰值均＞１５ｕｇ／Ｌ（平均为１７．２±１．９ｕｇ／Ｌ，ＬＶＥＦ值下降者的ｃＴｎＴ峰值在８—１５ｕｇ／Ｌ之间，ＬＶＥＦ值升高者的ｃＴｎＴ峰值均＜８ｕｇ／Ｌ。结论：前壁ＡＭＩ后ｃＴｎＴ峰值越高，心功能越差。
Objective To approach the relationship
between the peak of cardiac troponin T(cTnT) and cardiac function,left ventricle ejection fraction
(LVEF) in patients with acute myocardial infarction(AMI).Method The serum levels of cTnT was
tested in 24 patients with forewall AMI.LVEF,left ventricular end diastolic volume(EDV) and end
systolic volume(ESV)were determined by Simpson biplane formula.Results The peak of cTnT of
24 forewall AMI Was correlated to cardiac function,EDV and ESV;negatively correlated to
LVEF.Druing 6 months follow up,the peak value of cTnT of 3 died patients was >15ug/L(mean
17 2±1 9ug/L),the peak value of cTnT of decreased LVEF was 8 15ug/L,the increased LVEF
was <8ug/L.Conclusion After forewall AMI,the higher the peak value of cTnT,the poorer the left
ventricular function and prognosis
