Abstract
FUNDAMENTO: Os stents farmacológicos (SF) foram um grande avanço no tratamento da cardiopatia isquêmica, mas críticas têm sido feitas à extrapolação dos resultados favoráveis de ensaios clínicos para a prática clínica diária. OBJETIVO: Avaliar o uso dos stents farmacológicos (SF) no Brasil, entre os anos de 2000 e 2005. MÉTODOS: Por meio do banco de dados da Central Nacional de Intervenções Cardiovasculares (CENIC), da Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista, foram analisados todos os procedimentos com uso de SF entre os anos de 2000-2005. Os grupos foram divididos nos biênios (2000-2001(A), 2002-2003 (B) e 2004-2005(C)), e as características clínicas, angiográficas e os desfechos foram comparados. Análise estatística foi realizada com teste quiquadrado ou ANOVA, sendo significativo p<0,05. RESULTADOS: No período estudado foram avaliados 154.406 procedimentos, e os SF foram utilizados em 10.426 intervenções (7% do total). Observou-se progressivo e estatisticamente significativo aumento uso dos SF no período analisado: 0,14% em 2000-2001, 5% em 2002-2003, e 14% em 2004-2005 (p<0,0001). Após 2001, observou-se aumento dos índices de sucesso (96,58% em 2000-2001 (A), 99,69% em 2002-2003 (B) e 99,56 em 2004-2005 (C), A x B com p<0,001; B x C com p=0,015) e redução nas taxas de óbito hospitalar (1,59% no grupo A, 0,38% no grupo B, 0,66% no grupo C, p=0,59 para A x B; e p<0,0001 para B x C). CONCLUSÃO: O uso dos SF no Brasil cresceu significativamente nos últimos anos, com melhora dos índices de sucesso e diminuição do óbito hospitalar.
BACKGROUND: Drug-eluting stents (DES) represent a major advance in the management of ischemic heart disease, but the extrapolation of favorable results from clinical trials to the real-world practice has been criticized. OBJECTIVE: To assess the use of DES in Brazil between 2000 and 2005. METHODS: Using the database of the National Registry of Cardiovascular Interventions (CENIC - Central Nacional de Intervenções Cardiovasculares) of the Brazilian Society of Hemodynamics and Interventional Cardiology (SBHCI - Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista), all PCI procedures with DES implantation performed between 2000 and 2005 were analyzed. The groups were divided into the following biennia: 2000-2001(A), 2002-2003 (B), and 2004-2005 (C), and patient's clinical and angiographic characteristics were compared, as well as their short-term clinical outcome. Statistical analyses were performed using the chi-square test or ANOVA, and p values of less than 0.05 were considered to be statistically significant. RESULTS: A total of 154,406 PCI procedures were studied, and DES was used in 10,426 (7%) interventions. A progressive and statistically significant increase was found in the use of DES during the period studied: 0.14% from 2000 to 2001, 5% from 2002 to 2003, and 14% from 2004 to 2005 (p < 0.0001). After 2001, there was an increase in success rates (96.58% in 2000-2001 (A), 99.69% in 2002-2003 (B), and 99.56% in 2004-2005 (C), A x B with p < 0.001; B x C with p = 0.015) and a decrease in hospital mortality rates (1.59% in group A, 0.38% in group B, and 0.66% in group C, with p = 0.59 for A x B and p < 0.0001 for B x C). CONCLUSION: In Brazil, the use of drug-eluting stents increased significantly during recent years, resulting in higher success rates and lower hospital mortality.
