OBJECTIVE: To estimate in-hospital mortality and prevalence of complications of percutaneous transluminal coronary angioplasty (PTCA) in public hospitals. METHODS: Data for 2,913 PTCA were obtained from the Brazilian National Health System (SUS) Hospital Authorization Database in the city of Rio de Janeiro, Southeastern Brazil, between 1999 and 2003. After simple random sampling and data weighting, 529 medical records of patients undergoing PTCA, including all deaths, in four public hospitals (federal and state university, and federal and state reference hospitals) were studied. Comparison tests of mortality according to patient characteristics, comorbidities, complications, types of PTCA procedures, and indications for PTCA were performed using Poisson's regression models. RESULTS: The overall in-hospital mortality was 1.6% (range: 0.9-6.8%). The age distribution of mortality was as follows: 0.2% in patients younger than 50; 1.6% in those 50-69; and 2.7% in those older than 69. High mortality was seen in primary and rescue PTCAs: 17.4% and 13.1%, respectively; and mortality in elective PTCA was 0.8%. The main complications during PTCA were dissection (5%; mortality: 11.5%) and artery occlusion (2.6%; mortality: 21.8%). Bleeding was seen in 5.9% of the patients (mortality: 5.6%) and 3.0% required blood transfusion (mortality: 12.0%). The complication of acute myocardial infarction was seen in 1.1% of patients (mortality: 38%) and stroke was associated with a mortality of 17.5%. CONCLUSIONS: The cardiac in-hospital mortality was high when PTCA was performed for a patient with ST elevation acute myocardial infaction. Elective PTCA had mortality and complications levels above the expected in four public hospitals in the main city of Rio de Janeiro
