OBJECTIVE: To assess the clinical and demographic characteristics of a population with ischemic heart disease admitted in the final decades of the 20th century. METHODS: This study retrospectively assessed patients hospitalized with ischemic heart disease divided into the following 2 groups: acute group - 11.181 patients with acute myocardial infarction admitted from 1/1/82 to 12/31/94; and chronic group - 4.166 patients undergoing coronary artery bypass graft surgery from 1/1/84 to 12/31/94. RESULTS: In the acute group, an increase in the percentage of females (from 22.7% to 27.7%, P<0.001) and diabetic individuals (from 12.4% to 17.5%, P<0.001) was observed, as was an increase in age (from 57.4±11.5 to 59.9±12.1 years, P<0.05). In-hospital mortality was greater among females (27.8% and 15.7%, P=0.001), among diabetic individuals (24.2% and 17.8%, P=0.001), and among the elderly (60.9±15.2 and 57.7±11.8 years, P=0.0001). In the chronic group, an increase in the percentage of females (from 17.5% to 27.2%, P=0.001) was observed, as was an increase in age (from 56.3±8.6 to 60.5±9.6 years, P=0.0001). In-hospital mortality was greater among females (8.3% and 5.8%, P<0.05) and among the elderly (58.1±9.1 and 62.1±7.9 years, P=0.0001). CONCLUSION: The characteristics of the population studied with ischemic heart disease point towards a worse prognosis, due to the greater percentages of females, older patients, and diabetic patients, groups known to have greater in-hospital mortality
