Association Between the Malnutrition Status and All-Cause Mortality in Patients With Moderate and Severe Aortic Stenosis: A Prospective Cohort Study.

ABSTRACT:

Background

Malnutrition status is an important predictor of prognosis in patients after aortic valve replacement. However, the prognostic value of malnutrition status in patients with moderate-to-severe aortic stenosis is unclear. This study aimed to evaluate the effect of malnutrition on all-cause mortality in patients with moderate-to-severe aortic stenosis using the Patient Controlled Nutritional Status (CONUT) score, nutritional risk index, and prognostic nutritional index.

Methods and results

A total of 536 patients with moderate-to-severe aortic stenosis were selected in the ARISTOTLE (Aortic Valve Diseases Risk Factor Assessment and Prognosis Model Construction) study conducted between January 2013 and December 2022 in 3 academic institutions. Patients were grouped ac
