摘要：

      目的：探讨急性心肌梗死患者发病后早期进行运动心肺功能评定的可行性和必要性。方法：急性卵段抬高心肌梗死（AMI）患者40例。住院期进行三阶段康复治疗。出院前进行运动心肺功能评定，发病后3天进行血氮末端脑钠肽前体（NT-proBNR）浓度测定及超声心动图检查。结果：多元线性回归结果显示，患者的性别、年龄、梗死部位、测定距发病天数、左室射血分数（LVEF）、NT—proBNP均不是影响患者峰值及无氧阈时的代谢当量的主要因素。结论：出院前进行的运动心肺功能评定结果与患者的性别、年龄、梗死部位、测定距发病天数、LVEF、血浆NT—proBNP水平无明显相关性．出院前进行心肺功能评定是必要的。

Abstract:

      Objective: To observe the effects of early cardiopulmonary exercise test after acute myocardial infarction. Method: Forty inpatients with acute myocardial infarction were treated with 3 stages rehabilitation . Cardiopulmonary exercise test was underwent before discharge. NT-proBNP and echocardiography were carried 3 days after AMI. Result: The varieties of gender and age of patients, part of infarction, time of cardiopulmonary exercise test, left ventricular ejection fraction(LVEF) and NT-proBNP were not important factors that affected metabolism equivalents of the peak and anaerobic threshold. Conclusion: There was not obvious relationship between gender and age of patients, part of infarction, time of cardiopulmonary exercise test, LVEF and NT-proBNP with cardiopulmonary exercise test. Cardiopulmonary exercise test should be underwent before discharge.
