Résumé
Although limited walking ability at discharge is a known risk factor for adverse outcomes in older patients with heart failure (HF), the association between pre-admission limitations and adverse outcomes is unknown. Therefore, we evaluated the prevalence of a pre-admission limitation in walking ability and its relationship with post-discharge outcomes among patients with HF with reduced, mid-range, and preserved left-ventricular ejection fraction (HFrEF, HFmrEF, and HFpEF). We followed 2042 patients aged ≥65 years (HFrEF, n = 668; HFmrEF, n = 360; HFpEF, n = 1014) from a multicenter cohort study in Japan. A limitation in walking ability was defined as the necessity of any assistance or a walking aid. Adverse outcomes were defined as the composite of HF rehospitalization and all-cause death within 2 years after discharge. During 2978.0 person-years of follow-up, 563 patients were rehospitalized due to HF exacerbation and 103 patients died. In HFrEF, HFmrEF, and HFpEF groups, the prevalence of a pre-admission limitation in walking ability was 12.1%, 18.6%, and 21.1%, respectively, the crude hazard ratios [95% confidence interval] of a pre-admission limitation in walking ability were 2.46 [1.79-3.39], 1.34 [0.87-2.06], and 1.94 [1.53-2.47], and the adjusted hazard ratios were 2.21 [1.58-3.16], 1.19 [0.75-1.89], and 1.39 [1.06-1.82], respectively. A pre-admission limitation in walking ability is a predictor of post-discharge HF rehospitalization or all-cause death among patients with HFrEF and HFpEF, but not among patients with HFmrEF. Shortly after admission, information regarding pre-admission functional limitations should be obtained to better understand the risk of post-discharge adverse outcomes.

BACKGROUND
Although limited walking ability at discharge is a known risk factor for adverse outcomes in older patients with heart failure (HF), the association between pre-admission limitations and adverse outcomes is unknown. Therefore, we evaluated the prevalence of a pre-admission limitation in walking ability and its relationship with post-discharge outcomes among patients with HF with reduced, mid-range, and preserved left-ventricular ejection fraction (HFrEF, HFmrEF, and HFpEF).
METHODS
We followed 2042 patients aged ≥65 years (HFrEF, n = 668; HFmrEF, n = 360; HFpEF, n = 1014) from a multicenter cohort study in Japan. A limitation in walking ability was defined as the necessity of any assistance or a walking aid. Adverse outcomes were defined as the composite of HF rehospitalization and all-cause death within 2 years after discharge.
RESULTS
During 2978.0 person-years of follow-up, 563 patients were rehospitalized due to HF exacerbation and 103 patients died. In HFrEF, HFmrEF, and HFpEF groups, the prevalence of a pre-admission limitation in walking ability was 12.1%, 18.6%, and 21.1%, respectively, the crude hazard ratios [95% confidence interval] of a pre-admission limitation in walking ability were 2.46 [1.79-3.39], 1.34 [0.87-2.06], and 1.94 [1.53-2.47], and the adjusted hazard ratios were 2.21 [1.58-3.16], 1.19 [0.75-1.89], and 1.39 [1.06-1.82], respectively.
CONCLUSIONS
A pre-admission limitation in walking ability is a predictor of post-discharge HF rehospitalization or all-cause death among patients with HFrEF and HFpEF, but not among patients with HFmrEF. Shortly after admission, information regarding pre-admission functional limitations should be obtained to better understand the risk of post-discharge adverse outcomes.
