title: [Clinical and angiographic profile in coronary artery disease: hospital outcome with emphasis on the very elderly].
abstract: BACKGROUND
  knowing the risk factors and clinical manifestations of coronary artery disease (CAD) allows us to intervene more effectively with a particular population.
  
  
  OBJECTIVE
  to identify clinical and angiographic profiles of patients undergoing cardiac catheterization, treated at a tertiary hospital and treated by percutaneous coronary interventions (PCI).
  
  
  METHODS
  the study of 1,282 patients who underwent 1,410 cardiac catheterizations, selected from March/2007 to May/2008 from a database in a general hospital for diagnosis of coronary artery disease (CAD). Risk factors, indication for examination, technical details of PCI and in-hospital outcomes were prospectively collected.
  
  
  RESULTS
  there were 688 (54.0%) males, mean age 65.4 ± 10.9 years and 20.0% above 75 years age. The most frequent clinical condition was acute coronary syndrome (ACS) without ST-segment elevation (STS) (38.7%). The multi artery CAD occurred in 46.4%, PCI was indicated in 464 patients, 547 target lesions were treated (type B2 or C, 86.0%), and of these, 14.0% treated with drug eluting stents. Among those with AMI with STS, primary PCI was performed in 19.0% of the patients, from these, 77.0% were transferred from the origin hospitals late (late PCI) and had not received prior thrombolytic, and 4.0% had PCI rescue. Angiographic success was achieved in 94.2% of PCIs. Death occurred in 5.6% of patients, with average age of 75.2 ± 10.2 years.
  
  
  CONCLUSIONS
  the prevalence of elderly (20.1% being > 75 years) and male was observed. From the risk factors for CAD, the most common were systemic hypertension and dyslipidemia. There was a predominance of ACS. Age > 75 years old, multiarterial CAD and chronic renal failure were predictors of in-hospital deaths.
