Short-term (28 days) prognosis between genders according to the type of coronary event (Q-wave versus non–Q-wave acute myocardial infarction versus unstable angina pectoris)

      The type of acute coronary syndrome may account for different prognoses between men and women after myocardial infarction. This study assessed gender differences in 28-day mortality rates for first or recurrent Q-wave and non–Q-wave myocardial infarctions and unstable angina by using data from 5 registries that included 20,836 patients (24.8% women). Mortality rates were higher in women with first Q-wave myocardial infarction but not in the other patients after adjusting for confounding variables.
