Demographics, chronic diseases, systemic hemodynamics, and laboratory data were obtained at preoperative and later on admission and during the stay in the CVICU. <jats:italic>Outcome measures:<\/jats:italic> Postoperative organ dysfunction, nosocomial infections, length of mechanical ventilation, hospitalization and death. <jats:italic>Results:<\/jats:italic> A total of 2,743 patients (91%) of 3,025 patients who were admitted to the CVICU were enrolled in the study. Preoperative hypoalbuminemia was found in 325 patients (12%): hypoalbuminemia and cachexia in 21 patients (6%), hypoalbuminemia and liver insufficiency in 26 patients (8%), hypoalbuminemia and history of congestive heart failure in 102 patients (31%), and hypoalbuminemia alone in 176 patients (54%). Clinical features of preoperative hypoalbuminemia were age \u226575 years, female gender, left ventricular ejection fraction \u226435%, hematocrit \u226434%, serum creatinine \u22651.9 mg\/dL, systemic oxygen delivery \u2264350 mL\/min \u00b7 m<jats:sup>2<\/jats:sup>, acute stressful conditions (eg, infective endocarditis, acute myocardial infarction, or emergency surgery) and chronic obstructive pulmonary airway disease. Redo operations, combined valve and coronary artery bypass graft, mitral valve replacement, and thoracic aortic surgery were the commonest types of surgery performed in these patients. All types of hypoalbuminemia except for malnutrition cachexia increased the likelihood of postoperative organ dysfunction (cardiac, pulmonary, renal, hepatic, and neurologic), gastrointestinal bleeding, nosocomial infections, length of mechanical ventilation, stay in the CVICU, and hospital death. Cachectic hypoalbuminemia increased the requirement for postoperative parenteral nutrition and prolonged the length of stay in hospital. <jats:italic>Conclusion:<\/jats:italic> Preoperative hypoalbuminemia was attributed to malnutrition cachexia, liver insufficiency or congestive heart failure in &lt;50% of cardiac patients undergoing cardiovascular surgery. All types of hypoalbuminemia except for malnutrition cachexia increased the likelihood of postoperative organ dysfunction, nosocomial infections, prolonged mechanical ventilation, and death. The morbidity and mortality attributed to hypoalbuminemia could be explained by the underlying clinical characteristics rather than malnutrition cachexia in cardiac patients. <jats:italic>(journal of
