Key result
Higher pre-procedural nutrition intake was associated with a lower loss of relative muscle mass after transcatheter aortic valve implantation (P = .003).
Why the study?
Sarcopenia is highly prevalent among TAVI candidates, and the sarcopenia index has been proposed as a novel biomarker for muscle assessment.
Does higher pre-procedural nutrition intake reduce the loss of relative muscle mass after TAVI in patients with aortic stenosis?

Higher pre-procedural nutrition intake may protect against muscle mass loss following TAVI, and the sarcopenia index is a useful biomarker for muscle assessment in this population.
Sarcopenia is highly prevalent among candidates for transcatheter aortic valve implantation (TAVI). Sarcopenia index, the ratio of serum creatinine to serum cystatin C, has been proposed to be a novel biomarker in muscle assessment. Retrospective data were collected from patients diagnosed with aortic stenosis who underwent TAVI. Body composition assessment was conducted, and nutrition intake was recorded on a total of 127 patients. Sarcopenia index demonstrated a notably higher area under the curve (AUC) compared to bioelectrical impedance analysis in both male (AUC = 0.779) and female (AUC = 0.764) patients. Higher pre-procedural nutrition intake was found to be associated with a lower loss of relative muscle mass after TAVI (P = .003).

You et al. (2025) conducted a cohort in Aortic stenosis (n=127). Higher pre-procedural nutrition intake was evaluated on Loss of relative muscle mass after TAVI (p=.003). Higher pre-procedural nutrition intake was associated with a lower loss of relative muscle mass after transcatheter aortic valve implantation (P = .003).
