Impact of Preoperative Nutritional Status on the Postoperative Mortality and Morbidity in Patients Undergoing Valvular Heart Surgery

Impact of Preoperative Nutritional Status on the Postoperative Mortality and Morbidity in Patients Undergoing Valvular Heart Surgery

The investigators investigated the clinical impacts of preoperative nutritional status on mortality in patients undergoing valvular heart surgery. Preoperative nutritional status was evaluated by the prognostic nutritional index (PNI), Geriatric Nutritional Risk Index (GNRI), and controlling nutritional status (CONUT) score. The primary outcome was the association between preoperative nutritional status evaluated by PNI, GNRI, and CONUT score and postoperative mortality. The predictive discrimination ability for mortality between PNI, GNRI, and CONUT were compared. Risk factors for mortality were identified.

Inclusion Criteria:

• Patients who underwent valvular heart surgery from January 2013 to February 2018

Exclusion Criteria:

• Patients younger than 18 years
• Patients undergoing combined congenital heart surgery
• Patients undergoing transcatheter valve replacement
