摘要
急性心肌梗塞（ＡＭＩ）患者出院前作运动心电图试验有临床实际意义。我科自１９９４年６月至１９９６年４月，给５１例病情稳定的ＡＭＩ患者作此检查，男４１例（６３．４±６．４岁）。女１０例（７０．６±６．２岁）试验距发病３０．６±１４．７天（５～５２天），其中有６例广泛性梗塞。结果：（１）多数患者能达到与其年龄相应的运动量；（２）室性心律失常发生率较高（２５％）；（３）患者发生心绞痛、气急、疲劳及血压下降者亦较多（各约１９％）；（４）２６例患者作了冠脉造影（ＣＡＧ），显示运动心电图试验阳性者多为多支冠脉病变；敏感性为８４．６％，特异性达９２．３％。作者认为，只要掌握适应证及试验时间，作好监护急救准备，试验方法适宜，心肌梗塞患者出院前作运动试验基本是安全的。
It is clinically meaningful to do pre discharge treadmill exercise testing (TET) for patients with convalescent acute myocardial infarction (AMI). Our department performed such testng for 51 AMI patients from June 1994 to April 1996. Among them, 41 were males (63.4±6.4 years old) and 10 were females (70.6±6.2 years old). Timing of the testing was 30.6±14.7 days (5 52 dyas) after AMI. The localizations of infarction were anteroseptal of 21, anterior of 8 including extensive anterior of 5, inferior of 13, and others i.e. subendocardial and posterior of 9. All of the patients took antianginal drugs. The results were as follows: (1) Most of the patients could exercise to the degrees corresponding to those of their ages. (2) The incidence of ventricular arrhythmias was relatively high (25%), VT occurred in 3 patients. (3) Some patients had angina, dyspnea, fatigue or SBP drop during the testing, which means that they should be closely monitored during exercise even though asymtomatic before testing. (4) Twenty six patients were examined with CAG, the results showed that most patients with positive TET had multiple vessel disease, with a sensitivity of 84.6% and specificity of 92.3% . In conclusion, the testing is relatively safe so long as we select appropriate patients, testing methods and timing.
