Prevalence of risk factors at presentation and early mortality in patients aged 80 years or older with ST-segment elevation myocardial infarction.

Background: Elderly patients with ST-segment elevation myocardial infarction (STEMI) are at high risk for complications and early mortality; still, they are underrepresented in clinical trials and observational studies. We studied the risk profiles at presentation and early mortality in elderly (≥80 years) versus younger (<80 years) STEMI patients.

Design: This was a prospective cohort study.
