Association between frailty and physical performance in older patients with heart failure.

ABSTRACT:

Background

Frailty is an issue in patients with heart failure (HF). A Korean version of the frailty scale (K-FRAIL) has been developed.

Hypothesis

We aimed to analyze the relationship between the K-FRAIL scale and physical performance in patients with HF.

Methods

This study included 142 patients with HF aged ≥65 years from a single center. Muscular fitness was assessed using the handgrip test and knee extensor strength measurement. Aerobic capacity was assessed using the cardiopulmonary exercise test and 6-min walk test (6MWT). Frailty was assessed using the K-FRAIL questionnaire.

Results

Peak VO₂ and 6MWT scores significantly decreased as frailty worsened, but handgrip and knee extensor strength did not. In the multivariate analysis, peak VO_2</
