无症状心肌缺血(SMI)是指有心肌缺血的客观证据,但缺乏胸痛或心肌缺血相关的主观症状,此类患者经冠脉造影或死亡后尸检,几乎均证实冠状动脉主要分支有明显狭窄病变。重视对SMI的判断及治疗,对改善患者预后具有重要意义。近年来,我们对40例老年冠心病患者进行12导动态心电图监测,结果分析如下。 Asymptomatic myocardial ischemia (SMI) is an objective evidence of myocardial ischemia but lacks the subjective symptoms associated with chest pain or myocardial ischemia. Coronary angiography or post-mortem autopsy showed almost all of the major coronary artery branches Obvious stenosis. Emphasis on the judgment and treatment of SMI, to improve the prognosis of patients is of great significance. In recent years, we conducted 40 cases of elderly patients with coronary heart disease 12-lead ECG monitoring, the results are as follows.
