Abstract

Objective: To investigate the relationship between aortic stiffness and postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass grafting (CABG).

Methods: This study included 110 patients undergoing elective isolated CABG. Aortic stiffness was measured using a noninvasive oscillometric sphygmomanometer before surgery. Characteristics of patients with and without POAF were compared.

Results: POAF developed in 32 (29.1%) patients. Patients with POAF were older (63.7±8.6 vs. 58.3±8.4; P=0.014). Chronic obstructive pulmonary disease (COPD) was more common in patients with POAF (11.5% vs. 37.5%; P=0.024), whereas the frequency of hypertension, diabetes mellitus, smoking, and previous coronary artery disease did not differ. C-reactive protein and cholesterol levels were similar between patients with and without POAF. Left atrial diameter was greater in patients with POAF (35.9±1.6 vs. 36.7±1.7; P<0.039). Peripheral (p) and central (c) systolic and diastolic blood pressures were also similar between the groups, whereas both p and c pulse pressures (PP) were greater in patients with POAF (pPP: 44.3±11.9 vs. 50.3±11.6; P=0.018, cPP: 31.4±8.1 vs. 36.2±8.9; P=0.008). Pulse wave velocity (PWV) was significantly higher in POAF (8.6+1.3 vs. 9.4+1.3; P=0.006). PWV, pPR and COPD were independent predictors of POAF in multivariate regression analysis. In receiver operating characteristic analysis, PWV and pPP have similar accuracy for predicting POAF (PWV, area under the curve [AUC]: 0.661, 95% confidence interval [CI] [0.547-0.775], P=0.009) (pPP, AUC: 0.656, 95% CI [0.542-0.769], P=0.012).

Conclusion: COPD, PWV, and PP are predictors of POAF. PP and PWV, easily measured in office conditions, might be useful for detecting patients with a higher risk of POAF.
