Preditores e incidência de complicações vasculares após a realização de intervenções coronárias percutâneas: achados do registro IC-FUC / Predictors and incidence of vascular complications after percutaneous coronary interventions: findings from the IC-FUC registry

RESUMO

Introdução: As complicações vasculares (CV) são uma das principais causas de morbidade e mortalidade em pacientes submetidos a intervenções coronárias percutâneas (ICPs), porém estudos anteriores não refletem a prática atual. Objetivos: Avaliar a incidência de CV e seus preditores, em uma população de pacientes tratada com ICP contemporaneamente. Método: Estudo observacional de corte transversal, com implantes de stents coronários, de janeiro de 2000 a dezembro de 2007. As características clínicas e angiográficas e a evolução intra-hospitalar foram avaliadas e registradas em banco de dados informatizados. Foram excluídos aqueles com óbito hospitalar ou cirurgia cardíaca de urgência. CV foram definidas como sangramento maior, cirurgia vascular ou hematoma > 10 cm. Os dados foram analisados com SPSS 11,0, e as características dos pacientes com e sem CV foram comparadas com teste t de Student e teste do qui-quadrado. Os preditores independentes de CV foram identificados por análise de regressão logística múltipla. Resultados: Total de 4.595 pacientes com 5.485 stents implantados, com média de idade de 60,64 + - 10,65 anos e 32 por cento de mulheres. As ICPs foram realizadas pela via femoral...

ABSTRACT

Background: Vascular complications (VC) following percutaneous coronary intervention (PCI) are an important cause of morbidity and mortality. However, available data do not reflect current interventional cardiology practice. Objective: To determinate the incidence of VC and its predictors in a population treated with PCI in contemporary practice. Methods: Cross-sectional study with coronary stent implantation conducted from January/2000 to December/2007. Clinical and angiographic characteristics, as well as in-hospital evolution, were evaluated and recorded in a database. Exclusion criteria included in-hospital death and urgent heart surgery. VC were defined as major bleeding, vascular surgery or hematoma > 10 cm. Data were analyzed using SPSS 11.0 and the characteristics of patients with and without VC were compared using the Student's t test and chi-square test. Multiple Logistic Regression Analysis was performed to determinate the independent predictors of VC. Results: A total of 4,595 patients with 5,485 stents were included in this analysis. Mean age was 60.64 ± 10.65 years and 32% of the patients were female. The transfemoral approach was used in 95% of the PCIs and the transradial approach in 5%. Six French and 7 French introducers were used in 85% and 15% of the PCIs, respectively. A total of 162 (3.3%) patients experienced VC. The multivariate analysis determined that the only predictor for VC was the use of 7 French introducers (odds ratio = 3.05, 95% confidence interval = 1.2-7.8; p = 0.02)...
