一些研究证明,冠心病患者短暂性心肌缺血的发生率在清晨明显增高,该期间心肌梗塞和冠心病猝死发生率亦同时增加。为了确定夜间觉醒和起床对心肌缺血的触发作用,本研究观察了冠心病患者夜间觉醒和起床后又入睡的病人心肌缺血的发生情况。
Some studies have shown that the incidence of transient myocardial ischemia in patients with coronary heart disease significantly increased in the early morning, during which the incidence of myocardial infarction and sudden coronary death also increased. In order to determine the triggering effect of nocturnal awakening and wake-up on myocardial ischemia, this study examined the occurrence of myocardial ischemia in patients with coronary heart disease who awakened at night and fell asleep again.
