冠心病是≥65岁老年人的主要死亡原因。老年人冠心病的临床表现与年轻人有实质性区别,最常见的是老年人无症状心肌梗死发病率明显增加。这可能与心肌缺血的感觉减退有关,因此精确地评价老年人心绞痛痛感阈值(APT)非常重要。本文试图定量分析老年人APT延长及其与心脏自律功能的关系。
Coronary heart disease is the leading cause of death in ≥65-year-olds. The clinical manifestations of coronary heart disease in the elderly with a substantive difference between young people, the most common is the incidence of asymptomatic myocardial infarction in the elderly significantly increased. This may be related to a decrease in the feeling of myocardial ischemia, so it is important to accurately evaluate the angina pectoris threshold (APT) in the elderly. This article attempts to quantify the relationship between APT prolongation and cardiac autonomic function in the elderly.
