ABSTRACT

Introduction: Although coronary artery bypass surgery is an effective and durable treatment in patients with ischemic heart disease the risk of subsequent ischemic events persists due to the progression of coronary artery disease. Objective: To identify the possible association between the different atherogenic risk factors (smoking, hypertension (HBP), diabetes mellitus, obesity and dyslipidemia) and adverse cardiac events after coronary surgery. Methods: An observational, analytical and longitudinal study was conducted, which included 314 patients treated by myocardial revascularization surgery. Results: Patients were characterized by a high load of atherogenic risk factors mainly HBP (81.8%) and smoking (60.8%). The incidence of adverse events was 14.3%, of which myocardial infarction (8.9%), obstruction of the bridges (8.6%) and death of cardiovascular cause (8.3%) predominated. The diastolic diameter of the LV (54.2 ± 9.6 vs. 46.3 ± 11.1 mm) (p <0.001 *) was significantly higher in patients with adverse events and the LV ejection fraction (LVEF) significantly lower in this group (54.8 ± 12.9 vs 59.8 ± 10.2%) (p 0.004 *) compared to those who did not have adverse events. Patients with LVEF less than 50% and associated AHT showed a 2.36 times higher probability of adverse events than other variables (p <0.001 *). Conclusions: The combination of hypertension and decreased LVEF identifies patients with a high probability of developing adverse cardiac events after coronary surgery.
