近年研究证实无症状性心肌缺血(SMI)在冠心病患者中颇为常见,在所谓正常人群中也有发现。SMI可能引起急性心肌梗塞或猝死,但如能及时检出将可能改善患者的预后。在不同人群中SMI确切的流行情况还不清楚。我们对150名中年男性干部用动态心电图(DCG)及活动平板运动试验(ETT)检测缺血型ST段压低(STD),结果如下。
Recent studies have confirmed that asymptomatic myocardial ischemia (SMI) is quite common in patients with coronary heart disease, also found in the so-called normal population. SMI may cause acute myocardial infarction or sudden death, but if prompt detection will likely improve the patient’s prognosis. The precise prevalence of SMI in different populations is unclear. We examined ischemic ST-segment depression (STD) in 150 middle-aged male cadres with ambulatory electrocardiogram (DCG) and treadmill exercise test (ETT). The results are as follows.
