平板运动负荷试验检出无症状心肌缺血老人的预后

CLINICAL PROGNOSIS OF THE SE-NILE PATIENTS WITH ASYMPTOMATICMYOCARDIAL ISCHEMIA DETECTEDWITH PLATE EXERCISE TOLERANCETEST

采用西德产随带微机的心电图平板运动负荷试验检出无症状心肌缺血的老年患者３８例，进行２４个月的跟踪随访，结果４例发生心源性猝死，５例发生急性心肌梗塞，９例出现心绞痛，１１例心肌缺血加重。对照组３１例中有３例出现心绞痛，１例发生心源性猝死，２例可疑阳性。两组心脏意外事件（心肌梗塞＋猝死）发生率有显著差异住（Ｐ＜０．０５）．提示：运动诱发的老年无症状心肌缺血患者心脏意外事件发生率高。

follow-up survey to thirty-eight senile pa-tients with asymptomatic myocardial ischemia de-tected with ECG plate exercise tolerance test foundfour cases had cardiogenic sudden death, five had a-cute myocardiac infarction, nine had angina pec-toris, and eleven had more severe myocardial is-chemia. There were three cases of thirty-one con-trols having angina pectoris,one having cardiogenicsudden death and two doubtful positive.The inci-dence of heart accident in the two groups (myocar-diac infarction and sudden death) had significant dif-ference(P<0.05).It suggested that the senile pa-tients with the exercise-induced asymptomatic my-ocardial ischemia had high incidence of heart acci-dent .
