BACKGROUND: Myocardial revascularization in triple-vessel and left main coronary artery (LMCA) diseases can be performed by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The SYNTAX trial demonstrated equivalent clinical results in patients with low to moderate anatomical complexity undergoing CABG or PCI.
OBJECTIVES: To evaluate the incidence of cardiovascular events and rates of new myocardial revascularization in patients with LMCA and triple-vessel lesions undergoing PCI.
METHODS: Nonrandomized, observational cohort study that evaluated patients with triple-vessel or LMCA diseases undergoing PCI with drug-eluting stent in the period from June 2013 to May 2015 at the Hospital SOS Cardio in Florianópolis. Baseline data, main anatomical features, and clinical outcomes were reported during the in-hospital phase and during a 12-month follow-up.
RESULTS: In total, 46 patients with a mean age of 69.9 years were evaluated. At baseline, 39.1% had diabetes mellitus, 19.6% were smokers, 78.3% had dyslipidemia, 10.9% had chronic renal dysfunction, and 15.2% had moderate to severe ventricular dysfunction. As regards the number of arteries affected, 24% had triple-vessel disease and 76% had lesions in the LMCA. During the in-hospital period, there was a 4.34% rate of acute myocardial infarction without ST elevation. During this period, reintervention was not required and no deaths occurred. In the 12-month follow-up, mortality from cardiovascular causes was 4.35%. The rate of new revascularization was 4.3% by CABG and 2.2% by angioplasty.
CONCLUSION: The rates of cardiovascular events were low, indicating that PCI may be an acceptable alternative in selected cases. (Int J Cardiovasc Sci. 2016;29(4):262-269)
