BEHAVIORAL FACTORS IN TRANSIENT MYOCARDIAL ISCHEMIA

短暂性心肌缺血是冠心病的一种表现。 近年来，沉默的情节（即，无痛性）缺血已经被 在心率相对较低的情况下观察到， 急性冠状动脉血管收缩而不是心肌需求增加。 本项目探讨的问题是，这些事件是否 由特定的行为互动触发。 一个程序已经被 为便携式计算机开发，使患者能够定期 记录心脏监测期间的行为交互， 尽量减少对日常活动的干扰。 确定具体 短暂性心肌缺血发作的行为前因可能 导致非药物干预的发展， 预防

Transient myocardial ischemia is a manifestation of coronary heart disease. In recent years, episodes of silent (i.e., nonpainful) ischemia have been observed in the context of relatively low heart rates, suggesting mediation by acute coronary vasoconstriction rather than increased myocardial demand. The present project addresses the question of whether such episodes are triggered by specific behavioral interactions. A program has been developed for a portable computer which enables patients to regularly record behavioral interactions during periods of cardiac monitoring with a minimum of intrusion into daily activities. Identification of specific behavioral antecedents of episodes of transient myocardial ischemia could lead to the development of nonpharmacological interventions for their prevention.
