Transcatheter aortic valve implantation (TAVI) has been recognized as a standard therapy for severe aortic valve stenosis. However, since some patients who receive TAVI have poor outcomes, the predictors of clinical outcomes after TAVI are important. The aim of this study was to investigate the association between appetite and long-term clinical outcomes.

We screened consecutive cases who received TAVI at our medical center between July 2014 and October 2018. A total of 139 patients who received transfemoral TAVI were included as the final study population. They were divided into a good appetite group (n = 105) and a less appetite group (n = 34) according to their dietary intake rate (> 90%: good appetite group, ≤ 90%: less appetite group). We defined the intake rate as the average for breakfast, lunch, and dinner on the day just before discharge. We defined two-year major adverse cardiovascular and cerebrovascular events (MACCE) as a composite of cardiovascular death, myocardial infarction, any coronary revascularization, history of hospitalization due to heart failure, and disabling acute cerebral infarction. Kaplan-Meier analyses and multivariate Cox regression analysis were performed.

The median duration of the follow-up period was 372 (189-720) days. Kaplan-Meier curves showed that the less appetite group got MACCE more frequently (event free rate of the less appetite group: 76.5% versus the good appetite group: 94.3%, Log Rank P = 0.01). In multivariate Cox regression analysis, having less appetite was a significant predictor of two-year MACCE (HR 5.26, 95%CI 1.66-16.71, P < 0.01).

In conclusion, among the patients who received transfemoral TAVI, appetite status just before discharge was significantly associated with long-term outcome.
