SOLIS-OLIVARES, Carlos A  and  SOLIS-SOTO, Juan M. Comparative analysis of angioplasty versus surgery in multivessel coronary artery disease: A community hospital perspective. Rev. Mex. Cardiol [online]. 2012, vol.23, n.2, pp.64-71. ISSN 0188-2198.

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.
