Resumen breve

The purpose of this study is to look at the link between emotional stress and heart disease in men and women. Taking part in this study involves one clinic visit, one week of at home monitoring, and follow up phone calls every 6 months for 3 years.

Descripción detallada

In the U.S. and globally, coronary heart disease (CHD) is the number one killer of women. Despite scientific advances, it is unclear whether the pathophysiology of CHD differs between women and men. The study of CHD in women has historically been centered on older women, however, women with early onset CHD are informative for the study of early risk factors and pathophysiology. Furthermore, young women with a myocardial infarction (MI) have emerged as a group in need of special study as this group has higher mortality compared with men of similar age despite less severe disease. These disparities remain unexplained and suggest sex differences in the pathophysiology, risk factors and prognostic factors of acute MI.

The psychosocial sphere is a largely neglected area for CHD prevention in women. Social and emotional exposures mostly beginning early in life (depression, early life adversities, poverty and posttraumatic stress symptoms) are more common in younger women with MI compared with men and community controls. In addition to being more prevalent, it is possible that emotional stress is a stronger risk factor in young women than other groups. A significant challenge, however, is to measure stress in a valid way.

Building on previous work, the current project will clarify sex differences in pathways of risk linking emotional stress to mental stress-induced myocardial ischemia (MSI) and cardiovascular outcomes in young post-MI patients. Within 8 months of MI, 300 patients ≤60 years of age (at the time of the MI), 50% women, will be tested in the lab with a stress challenge to asses MSI using an established protocol with myocardial perfusion imaging. Participants will be monitored at home for 1 week, and then followed for clinical events for 3 years.
