本文旨在修正早期的报导并包括更新的研究。定义和发生率隐性心肌缺血是指具有客观证据的无疼痛或未达到通常疼痛程度的心肌暂时缺血。关键是“客观证据”。有关隐性心肌缺血的发病情况目前仍难以获得精确的数据,据患者的临床表现可分为Ⅲ型。I型:完全无临床症状而具备隐性心肌缺血的客观依据。Ⅱ型:无症状的已稳定的心肌梗塞,但证明有隐性心肌缺血。Ⅲ型:有明显的心绞痛,在疼痛间歇时出现隐性心肌缺血。病理生理学疼痛缺乏的原因是神秘的(基至心脏疼痛机制本身仍留有疑问)。通过经皮肤 This article aims to revise earlier reports and includes updated research. Definition and Incidence of Recessive Myocardial Ischemia refers to transient myocardial ischemia with objective evidence of pain-free or general painfulness. The key is “objective evidence.” The incidence of occult myocardial ischemia is still difficult to obtain accurate data, according to the clinical manifestations of patients can be divided into type Ⅲ. Type I: Completely without clinical symptoms but with objective evidence of occult myocardial ischemia. Type II: Asymptomatic stable myocardial infarction, but evidence of implicit myocardial ischemia. Type Ⅲ: a significant angina pectoris, intermittent occult myocardial ischemia occurred in the pain. Pathophysiology The reason for the lack of pain is mystical (base-to-heart pain mechanisms remain problematic). Through the skin
