Gender differences in triggering of acute myocardial infarction

There is growing evidence that the onset of acute myocardial infarction (AM I) is related to numerous endogenous and exogenous daily rhythms. AMI may o ccur at any time of day, but peak incidence occurs during the morning.(1-5) The morning increase in adrenergic activity, hormone levels, and coagulabi lity could create a transient risk state, and thus precipitate AMI.(6-11) S ome daily activities or unusual events produce similar physiologic response s and it is currently accepted that physical exertion, mental stress, and o ther conditions may trigger AMI.(1,2,4,12-17) We have reported that infarct ions of anterior and inferior wall may have different typical triggers.(1) In this study, we report on the role of gender in triggering AMI.
