Objective: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery. The aim of this multicenter study was to determine the relationship between POAF and patients' progress in early rehabilitation after heart valve surgery. Methods: We enrolled 302 patients (mean age, 69±10 years) who had undergone heart valve surgery. POAF was monitored using continuous electrocardiogram telemetry, and the Short Physical Performance Battery (SPPB) was used to assess lower-extremity function before surgery and at the time of discharge. Progress in early rehabilitation was evaluated by the duration from the surgery to independent walking. We determined factors associated delayed early rehabilitation and evaluated the interplay of POAF and delayed early rehabilitation in increasing the risk of decline in lower-extremity function from preoperatively to hospital discharge. Results: Multivariate analysis determined POAF to be independent predictors of delayed early rehabilitation after heart valve surgery (OR: 3.906, P =.01). The association between delayed early rehabilitation and decline in lower extremity function was stronger in patients with POAF (OR: 2.73, P =.041) than in those without (OR: 2.22, P =.052). Conclusions: POAF was clinical predictors of delayed early rehabilitation in patients undergoing heart valve surgery. The combination of POAF with delayed early rehabilitation conferred a high risk of decline in lower-extremity function during hospitalization.

Background: The aim of the present study was to compare the end-tidal O2 pressure (PETO2) to end-tidal CO2 pressure (PETCO2) in cardiac patients during rest and during 2 states of exercise: at anaerobic threshold (AT) and at peak. The purpose was to see which metabolic state, PETO2 or PETCO2, best correlated with exercise limitation. Methods and Results: Thirty-eight patients with left ventricular (LV) ejection fraction <40% underwent cardiopulmonary exercise testing (CPX). PETO2 and PETCO2 were measured during CPX, along with peak O2 uptake (VO2), AT, slope of the increase in ventilation (VE) relative to the increase in CO2 output (VCO2) (VE vs. VCO2 slope), and the ratio of the increase in VO2 to the increase in work rate (ΔVO2/ΔWR). Both PETO2 and PETCO2 measured at AT were best correlated with peakVO2, AT, ΔVO2/ΔWR and VE vs. VCO2 slope. PETO2 at AT correlated with reduced peak VO2 (r=-0.60), reduced AT (r=-0.52), reduced ΔVO2/ΔWR (r=-0.55) and increased VE vs. VCO2 slope (r=0.74). PETCO2 at AT correlated with reduced peak VO2 (r=0.67), reduced AT (r=0.61), reduced ΔVO2/ΔWR (r=0.58) and increased VE vs. VCO2 slope (r=-0.80). Conclusions: PETCO2 and PETO2 at AT correlated with peak VO2, AT and ΔVO2/ΔWR, but best correlated with increased VE vs. VCO2 slope. PETO2 and PETCO2 at AT can be used as a prime index of impaired cardiopulmonary function during exercise in patients with LV failure.
