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，静止性(即非痛性)缺血发作 在心率相对较低的情况下观察到的，暗示调解 通过急性冠脉血管收缩，而不是增加心肌需求。 本项目涉及的问题是，此类事件是否 由特定的行为互动触发。一项计划已经完成 为便携式计算机开发的，使患者能够定期 记录心脏监测期间的行为交互作用 最大限度地减少对日常活动的干扰。识别特定的 短暂性心肌缺血发作的行为先兆可能 导致对其进行非药物干预的发展 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.
