ONE YEAR FOLLOW-UP OUTCOME IN MULTIVESSEL PERCUTANEOUS CORONARY INTERVENTION

摘要

Introduction: Percutaneous coronary intervention in multivessel disease is a valid op-tion for revascularization. Objective: To assess the outcomes of multivessel percutaneous coronary intervention in patients with multivessel disease; and to identify variables that are predictors of major adverse cardiac events. Method: A retrospective cohort and long-term survival study at the Hermanos Amei-jeiras Hospital. Minimum follow-up was one year. The survival function was estimated by the Kaplan-Meier analysis, and univariate and multivariate analysis were used to identify predictors of major adverse cardiac events. Results: A total of 191 lesions were treated in 87 patients, 11.5% of them had three-vessel disease. The procedure was successful in 97.7% of cases, and radial access was the most commonly used (67.8%). The left anterior descending artery was the most frequently treated one (41%) and 77% of lesions treated were complex lesions (B2 and C). Some type of major adverse cardiac events occurred in 14.9% of the patients; 3.4% of them died from cardiac causes, 2.3% suffered a nonfatal acute myocardial infarction and 10.3% required repeat revascularization. The rate of adverse event-free survival at one year was 89.16%.Three-vessel disease was the only variable that predicted, independently, the occurrence of major adverse cardiac events at one year [p = 0.01, OR 5.03 (1.18 to 21.3, 95% CI)]. Conclusions: Multivessel percutaneous coronary intervention, in properly selected cases, leads to good results one year after surgery. Three-vessel disease was asso-ciated, independently, with the occurrence of major adverse cardiac events during the follow-up.
