Mental Stress-Induced Myocardial Ischemia and Cardiovascular Events in Women after a Premature Myocardial Infarction: A Prospective Cohort Study

Background. Women with premature myocardial infarction (MI) have worse outcomes than similarly aged men despite less severe disease, and stress-related factors have been implicated. We examined sex differences in the association of mental stress-induced myocardial ischemia (MSIMI) with cardiovascular outcomes after premature MI and explored vascular and inflammatory mechanisms. Methods. We studied 602 individuals (mean age 51 years; 46% women) within 8 months of MI who underwent 99mTc-sestamibi myocardial perfusion imaging at rest and after mental stress. MSIMI was defined as a summed differen
