Answer

As previously mentioned, approximately 1.5 million Americans per year have an AMI, with a third of these events proving fatal. The survivors of MI have a poor prognosis, carrying a 1.5- to 15-fold higher risk of mortality and morbidity than the rest of the population.

Historically, for example, 25% of men and 38% of women die within 1 year after having an MI, although these rates may overstate the 1-year mortality today, given advances in the treatment of CHF and sudden cardiac death. Among survivors, 18% of men and 34% of women have a second MI within 6 years, 7% of men and 6% of women die suddenly, 22% of men and 46% of women are disabled with CHF, and 8% of men and 11% of women have a stroke.

According to a prospective study using data from the Coronary CT Angiography Evaluation for Clinical Outcomes: An International Multicenter (CONFIRM) Registry, incident mortality and MI rates do not differ significantly between men and women among patients matched for age, risk factors, symptoms, and extent of CAD. [22] These findings conflict with those from the Women’s Health Initiative, which found that in women with nonspecific or atypical chest pain, the risk of nonfatal MI is twice as great as that in men.
