Koroner Arter Baypas Cerrahisi Sonrası Atriyal Fibrilasyon: Risk Faktörleri.

Objective: The aim of this study was to determine the risk factors in atrial fibrillation (AF), which is the most common rhythm disorder observed after coronary artery bypass graft (CABG) surgery, and to show whether there is a correlation between C-reactive protein (CRP) and AF. Methods: A total of 250 patients who would undergo coronary artery surgery were retrospectively included in the study. Demographic data, peroperative and postoperative variables of all patients, daily CRP and AF follow-ups until the 6th postoperative day and treatment protocols of AF patients were recorded. Results: AF was detected in 43 (17.2%) of the patients who were followed up. It was found that there was a statistically significant relationship in the multivariate analysis between advanced age, hypertension (HT) and use of preoperative calcium channel blocker and AF (p<0.05). CRP values reached the highest value on the 2nd postoperative day. Although AF was seen in 14 patients (5.6%) in this period, no relation was found between increased CRP levels and the development of AF (p>0.05). It was observed that the length of intensive care and hospital stay of patients with AF was statistically significantly longer (p<0.05). Conclusion: It was found that older hypertensive patients who preoperatively used calcium channel blocker had a higher risk of developing AF. Duration of ICU and hospital stay was longer, and no correlation was found between AF and CRP. [ABSTRACT FROM AUTHOR]
