Tendências seculares da populaçäo com doença isquêmia do coraçäo internada do Instituto do Coraçäo - Säo Paulo / Secular trends in a population with ischemic heart disease admitted to the Instituto do Coraçäo in Säo Paulo

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 percent to 27.7 percent, P<0.001) and diabetic individuals (from 12.4 percent to 17.5 percent, 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 percent and 15.7 percent, P=0.001), among diabetic individuals (24.2 percent and 17.8 percent, 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 percent to 27.2 percent, 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 percent and 5.8 percent, 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

Características demográficas da populaçäo submetida à cinecoronariografia no Instituto do Coraçäo da Faculdade de Medicina da USP de 1986 a 1995 / Demographic characteristics of the population undergoing cine coronary angiography at the Instituto do Coraçäo of the Medical School of USP from 1986 to 1995

OBJECTIVE: To obtain information about the profile and behavior of a population with ischemic heart disease undergoing cine coronary angiography and to determine disease severity. METHODS: Retrospective study assessing patients hospitalized at InCor from 1986 to 1995, in which the variables age, sex, and number of major coronary arteries with obstruction degree > 40 percent were analyzed. RESULTS: We studied 18,221 patients and observed a significant increase in the number of females (22.8 percent to 25.2 percent, P=0.001) and an increase in age (57.1±29.3 to 60.4±10.7 years, P=0.0001). A significant increase in the incidence of multivessel disease was observed, which was more frequent among males (69.2 percent and 64.5 percent) and among the older patients (59.8±9.8 and 56.8±10.7 years, P=0.0001). A reduction in the incidence of single-vessel disease was also observed (66.2 percent vs 69.2 percent and 33.8 percent vs 30.5 percent, respectively, P<0.0001). CONCLUSION: A change in the profile of the population studied was observed as follows: patients undergoing cine coronary angiography at InCor were older, had a greater number of impaired major coronary arteries, and the number of females affected increased, leading to indices suggestive of a poorer prognosis
