冠状动脉疾病死亡的病例中,半数以上是突然死于症状开始1小时内;其中多数是由于心外膜大冠状动脉严重粥样硬化。心脏猝死机理多数为心室颤动,病理基础常是心肌缺血。近来临床研究证明,隐性心肌缺血与心脏猝死有关。Droste等对30例隐性心肌缺血的研究发现,这类患者前臂缺血性疼痛阈值较高,疼痛耐受性较强。 More than half of all deaths from coronary artery disease were due to sudden death within 1 hour of onset of symptoms; most of them were due to severe atherosclerotic coronary atherosclerosis. Most of sudden cardiac death ventricular fibrillation, pathological basis is often myocardial ischemia. Recent clinical studies have shown that occult myocardial ischemia and sudden cardiac death. Droste and other 30 cases of occult myocardial ischemia study found that such patients with higher forearm ischemic pain threshold, pain-tolerant.
