RESUMEN

Introdução: O escore SYNTAX estratifica a complexidade angiográfica e estabelece o prognóstico de portadores de doença triarterial e/ou com lesão de tronco, sendo uma importante ferramenta para decidir a melhor estratégia de revascularização. Avaliamos o impacto do escore SYNTAX no prognóstico de pacientes com doença arterial coronariana multiarterial da prática clínica tratados por intervenção coronária percutânea. Métodos: Identificamos no Registro SAFIRA pacientes com acometimento multiarterial tratados eletivamente com stents farmacológicos. Os pacientes foram agrupados em escore SYNTAX ≤ 8; escore SYNTAX > 8 e ≤ 16; e escore SYNTAX > 16, e comparados quanto aos eventos cardíacos adversos maiores. Resultados: No período de 2009 a 2014, identificamos 244 pacientes, que preencheram os critérios de inclusão para o estudo. Foram distribuídos em escore SYNTAX ≤ 8 (n = 61; 25%), > 8 e ≤ 16 (n = 116; 47,5%), e > 16 (n = 67; 27,5%). A média de idade foi de 64,6 ± 11,5 anos e 73% eram do sexo masculino. O escore SYNTAX variou de 1 a 39, com média de 13,4 ± 6,8. No período de 3,6 ± 2,1 anos, observaram-se maiores taxas de eventos cardíacos adversos maiores no grupo > 16 (4,9% vs. 6,9% vs. 11,9%; p < 0,01), às custas de maior revascularização do vaso-alvo (1,6% vs. 2,6% vs. 7,5%; p = 0,08).

Background: The SYNTAX score stratifies the angiographic complexity of coronary artery disease and establishes the prognosis of patients with triple vessel and/or left main coronary artery disease, being an important tool to decide the best revascularization strategy. We assessed the impact of the SYNTAX score in the prognosis of a daily practice population with multivessel coronary artery disease treated by percutaneous coronary intervention with drug-eluting stents. Methods: We identified in the SAFIRA Registry elective patients with multivessel coronary artery disease treated with drug-eluting stents. Patients were grouped in SYNTAX score ≤ 8; SYNTAX score > 8 and ≤ 16, and SYNTAX score > 16, and clinical outcomes in terms of major adverse cardiac events were stratified according to the SYNTAX score groups. Resultados: Between 2009 and 2014, we identified 244 patients that met the study inclusion criteria. Patients were distributed in those with SYNTAX score ≤ 8 (n = 61; 25%), > 8 and ≤ 16 (n = 116; 47.5%), and > 16 (n = 67; 27.5%). Mean age was 64.6 ± 11.5 years and 73% were male. The SYNTAX score ranged between 1 and 39, with an average of 13.4 ± 6.8. In the follow-up period of 3.6 ± 2.1 years, there were higher rates of major adverse cardiac events in group > 16 (4.9% vs. 6.9% vs. 11.9%; p < 0.01) due to a higher incidence of target vessel revascularization (1.6% vs. 2.6% vs. 7.5%; p = 0.08).
