Abbreviations: CreatCl, creatinine clearance; DM, Diabetes Mellitus; LVEF, left ventricle ejection fraction; NYHA, New York Heart Association; sPAP, systolic pulmonary artery pressure.
The median length of stay was 12 (IQR:9-22) days. The incidence rate of in-hospital complications was 28.7%. Eleven patients (10,2%) required re-exploration of the mediastinum for bleeding; 2 patients (1.9%) had a perioperative myocardial infarction. Acute kidney injury requiring renal replacement therapy occurred in 9 patients (8.3%) and stroke in 4 (3.7%). The list of major complications are listed in Table 5.
On univariable analysis, DM (p=0.012), sPAP (p=0.019) and obesity (p=0.013) were significant predictors of in-hospital complications and CreatCl (p=0.015) was associated with reduced risk of in-hospital complications. On multivariable analysis, sPAP (OR 1.023 CI95: 1.0-1.05; p=0.047) and obesity (OR 6.28 CI95: 1.48-25.69; p=0.013) increased the risk of early morbidity in 1.02 and 6.28 folds, respectively (Table 6).
