ABSTRACT
INTRODUCTION:
Several factors intervene in the evolution of the characteristics of Coronary artery bypass grafting (CABG), such as demographic changes, surgical technique, and perioperative care. Our objective was to analyze the evolution of the characteristics of coronary artery disease in patients treated with CABG and its immediate results.METHODS:
In an analytical study, we analyzed a cohort of patients with isolated CABG from January 2006 to December 2008 and from January 2016 to December 2018 in Hospital Clínico Regional Concepción, Chile. After the ethics committee's approval, we reviewed the database and surgical protocols. We used Chi-square and U Mann Whitney tests for statistical analysis (SPSSv25®), considering significant p < 0,05.RESULTS:
We analyzed 1,400 isolated CABG, 658 from the first period and 742 from the second, with a mean age of 62.0 ± 8.7 and 64.6 ± 9.3 respectively (p < 0.001). The subgroup with ventricular dysfunction in the second period showed a significant increase in diabetes mellitus, chronic obstructive pulmonary disease, acute myocardial infarction (AMI), and severe ventricular dysfunction. The second group decreased off-pump surgery and increased the use of ≥ 2 arterial grafts (p < 0.05). The Additive EuroSCORE I increased from 3.6 ± 2.5 to 4.4 ± 2.7 (p = 0.001). High-risk subgroup 137 (20.8%) to 236 (31.8%), p < 0.001. Mortality of 13 (1.98%) and 16 (2.2%) in the first and second group respectively, p = 0.813.CONCLUSION:
There was a significant increase in the estimated surgical risk; however, mortality remained unchanged. The increase in surgical risk is consistent with the increase in mean age and prevalence of comorbidities, as well as the increase in severe ventricular dysfunction in the group ofpatients with ventricular dysfunction and recent AMI in the second period.
