Introduction New medical therapies and technical advances, as well as the increased experience in interventional cardiology, made it necessary to carry out this new registry, the CONAREC XIV protocol, on the use of percutaneous coronary intervention (PCI), a procedure that is safe and effective for the treatment of coronary disease. Objective To evaluate the characteristics of patients, indications, and results of PCI in our country. Material and Methods A prospective consecutive registry was performed during 6 months in patients that underwent PCI at centers that had a Residency in Cardiology. Background, clinical condition upon admission, therapy, results and in-hospital complications were assessed. Results The recorded patients were 1,500. The average age was 62,8 ± 10,8 years and 78,3% were males. Background: 72% arterial hypertension, 56,6% dyslipemia, 19,2% diabetes and 22,4% smokers. Clinical conditions were: 20% asymptomatic, 16,2% stable chronic angina, 45% non ST segment elevation acute coronary syndrome (NSTE-ACS), 19% ST elevation acute coronary syndrome (STE-ACS). In 74,7% of the cases PCI was performed in one of the vessels. Stents were used in 94,5% of the cases and in 18,7%, drug eluting stents were used. The use of functional tests previous to PCI in stable patients was of 53,9%, whereas in STE-ACS was of 31,6%. The median evolution time up to PCI in the STEACS was 1 day with 25-75% (ICR) interquartile range of 0 to 3. In ST-AMI, the door-to-balloon time was 60 minutes (ICR 40-105) and mortality was 8%. Conclusions PCI is used mainly in the treatment of acute coronary syndromes. High use rate of stents and drug eluting stents was evident. The use of functional tests was low. The complications rate was similar to those shown in international registries.
