RESUMO
Introducción: Hasta 60% de los casos tratados con intervención coronaria percutánea (ICP) o cirugía (CRVC) tienen enfermedad coronaria de múltiples vasos (ECMV). Objetivo: Comparar la evolución clínica de estos pacientes después de su comparativo, de una cohorte tratada por ECMV con CRVC o ICP más stents farmacoactivos o bioactivos entre enero de 2004 a julio de 2011. Se utilizó expediente clínico, consignando eventos cardiovasculares adversos. Resultados: Ingresaron 134 pacientes, predominando varones con enfermedad trivascular y angina estable con un seguimiento de 35.7 ± 20.4 meses. El grupo quirúrgico tuvo más dislipidemia (41.9 vs 36.7%), diabetes (59.5 vs 38.3%), hipertensión arterial (67.6 vs 60%), infarto del miocardio antiguo (37.8 vs 23.3%) y lesión tipo C en la arteria descendente anterior (63.9 vs 30.4%), p < 0.05 para todas. Los tratados con ICP tuvieron más necesidad de revascularización repetida (30.50 vs 2.73%) p < 0.01, recurrencia de angina (44 vs 20%), ergometrías positivas (39 vs 18%), hospitalizaciones (25 vs 9%) y deterioro funcional según la New York Heart Association III o IV (22 vs 11%), p < 0.05 para todos. Conclusión: En pacientes de un hospital comunitario con ECMV, la ICP presenta una recurrencia superior de isquemia y revascularización repetida comparada con la CRVC.
Introduction: 60% of the patients treated with coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) suffer from multivessel coronary artery disease. Objective: Our objective was to compare the clinical course of patients with this diagnosis after revascularization. Methods: We consulted and compared the clinical records of a multivessel coronary artery disease cohort treated with either coronary artery bypass grafting or angioplasty with drug eluting stents or bioactive stents between January 2004 and July 2011, consigning adverse cardiovascular events. Results: 134 patients, mostly male, with 3-vessel disease and stable angina, were followed up for 35.7 ± 20.4 months. Dyslipidemia (41.9 vs 36.7%), diabetes mellitus type 2 (59.5 vs 38.3%), hypertension (67.6 vs 60%), old myocardial infarction (37.8 vs 23.3%) and type C lesion in left anterior descendent artery (63.9 vs 30.4%) were all more frequent in the surgery group (p < 0.05). On the other hand, the angioplasty treated patients needed more frequently revascularization (30.50 vs 2.73%; p < 0.01) and hospitalization (25 vs 9%) and had more often angina (44 vs 20%), positive ergometry (39 vs 18%), and functional impairment type New York Heart Association III/IV (22 vs 11%) (p < 0.05). Conclusion: In patients at a community hospital with multivessel coronary artery disease, PCI has a higher recurrence of ischemia and repeated revascularization compared to CABG.
