The aim of this study was to determine nutritional status and malnutrition risk among patients undergoing coronary bypass surgery at preoperative and postoperative terms via two different screening tools (Malnutrition Universal Screening Tool-MUST and Nutritional Risk Screening-NRS-2002), dietary records, blood parameters, body composition analysis (Bioelectrical Impedance Analysis-BIA). Percent body fat and fat mass decreased (p<0.001); while lean body mass and total body water increased at postoperative term compared to preoperative term (p<0.01). Energy intake, carbohydrate, protein and fat percents decreased at postoperative term compared to preoperative term (p<0.01). Serum albumin and total protein were negatively associated with malnutrition risk (p<0.05). While malnutrition risk increased according to MUST, BMI values decreased at preoperative and posterative (p<0.05). According to postoperative NRS-2002, percent body fat was higher whereas lean body mass was lower among patients at risk (p<0.01). Medium risk patients consumed less protein than low risk patients according to preoperative MUST assessment (p<0.05). Energy, carbohydrate, protein, fat intake, g/kg protein and energy intake in percent according to daily recommendation were significantly lower in patients under malnutrition risk according to NRS-2002 (p<0.01). Malnutrition screenig tools as well as food consumption, body composition, blood parameters should be taken into consideration in terms of determination of malnutrition risk among patients undergoing coronary bypass surgery.
