HMH. MiyataKindai University Hospital KMKoichiro MatsumuraKindai University Sakai Hospital KHKazue HamamuraKindai University Hospital

Key Points

To investigate the relationship between nutrition status, muscle mass, and 1-year mortality in patients with aortic stenosis treated with transcatheter aortic valve implantation.
Evaluated nutrition status and muscle mass in patients prior to valve implantation

Structured PICO

Does the combined assessment of nutritional status and muscle mass improve prognostic accuracy for 1-year mortality in patients with aortic stenosis undergoing TAVI?

Population

Patients with aortic stenosis undergoing transcatheter aortic valve implantation (TAVI)

Intervention

Combined assessment of nutritional status and muscle mass

Comparator

Individual markers of nutritional status or muscle mass

Outcome

1-year mortalityhard clinical

Combined assessment of nutritional status and muscle mass improves risk stratification and prognostic accuracy for 1-year mortality in patients undergoing TAVI.

Abstract

The combined assessment of nutritional status and muscle mass improves the identification of high-risk patients undergoing transcatheter aortic valve implantation and enhances the prognostic accuracy beyond individual markers. This approach may aid in refining the risk stratification and tailoring the perioperative management of patients undergoing TAVI.
