Behavior and Myocardial Ischemia. Recent ambulatory electrocardiography studies reveal that myocardial ischemia out‐of‐hospital exhibits features that may not be evident during controlled exercise testing. Specifically, out‐of‐hospital ischemia: (1) is more frequently asymptomatic or silent; (2) occurs during a wide variety of mental, as well as physical, activities; (3) is triggered at relatively low heart rate elevations compared to exercise; (4) exhibits a circadian rhythm; and (5) exhibits variability over time. This article reviews recent field and laboratory research suggesting that behavioral factors, including mental stress, may contribute to the typical features of myocardial ischemia out‐of‐hospital.
