Myocardial infarction (MI) is a serious health problem which causes substantial morbidity and mortality. The seriousness of coronary artery disease is heightened by the fact that approximately a third of patients present with sudden death as their first manifestation,1 and efforts to prevent infarctions before they occur have fuelled an area of research which investigates inciting events, or "triggers", of MI, arrhythmias, and sudden death. The idea that an MI can be incited by an identifiable event is an old one, but research into cardiovascular triggers has only recently begun to elucidate specific culprits. Triggering research continues to evolve in concert with our understanding of the pathophysiological mechanisms involved in MI, with the eventual hope of developing effective preventive strategies.
The circadian rhythm in the incidence of cardiac events was one of the first triggering patterns to be discovered; peak frequencies of MI and sudden cardiac death were observed in
