Sumario: | The aim of the study was to perform a comprehensive fundamental analysis of the factors of inflammation, oxidative stress, fibrosis, myocardial dysfunction, ischemia and omega-3 index associated with postoperative atrial fibrillation (POAF) after coronary artery bypass graft (CABG) surgery in patients with coronary artery disease. The study involved 158 patients who were admitted to the hospital to undergo CABG surgery. Patients were divided into two groups: group 1 comprised 111 patients without POAF (82% males, median age—62.0 (56.0; 66.0) years), and group 2 comprised 47 patients with POAF (84.4% males, median age—65.0 (61.0; 70.0) years). POAF occurred 5.2 (2.0; 7.0) days after CABG. In all the patients, we evaluated laboratory tests before and 3–4 days after CABG. All the patients also underwent echocardiography. According to results of multifactorial regression analysis, the odds ratio of POAF development for left atrial diameter >41 mm was 4.3 (95% confidence interval (CI) 2.0–9.7, p < 0.001), interleukin (IL)-6 postoperative levels >22.07 pg/mL—3.0 (95% CI 1.4–8.2, p = 0.006), IL-8 postoperative levels >9.67 pg/mL—2.3 (95% CI 1.2–7.3, p = 0.006), superoxide dismutase postoperative levels in plasma >1100.5 U/g—3.2 (95% CI 1.4–9.2, p = 0.03), glutathione postoperative levels ≤0.194 micromole/g of hemoglobin—1.9 (95% CI 1.2–6.3, p < 0.001), glutathione peroxidase postoperative levels ≤17.36 millimole/g of hemoglobin—2.2 (95% CI 1.1–8.2, p < 0.001), glutathione reductase postoperative levels ≤2.99 millimole/g of hemoglobin—2.3 (95% CI, 1.1–5.7, p < 0.001), malondialdehyde postoperative levels >1.25 micromole/g of hemoglobin—2.0 (95% CI, 1.2–7.9, p < 0.001), NO postoperative levels in plasma >36.4 micromole/L—1.5 (95% CI, 1.1–5.9, p < 0.001) and omega-3 index ≤1.59%—2.6 (95% CI 1.5–9.1, p < 0.001). Our study showed that increased left atrial diameter, high postoperative levels of inflammatory factors, oxidative stress, fibrosis indicators and omega-3 index were associated with POAF in patients who underwent CABG. |
