Associations between in-hospital daily protein intake and adverse clinical outcomes in older patients with heart failure.

ABSTRACT:

Aims

The adverse effects of low daily protein intake (DPI) on clinical outcomes in patients with heart failure (HF) are known; however, an optimal DPI to predict event adverse outcomes remains undetermined. Moreover, whether protein restriction therapy for chronic kidney disease is applicable in patients with HF and renal dysfunction remains unclear.

Methods and results

In this single-centre, ambispective cohort study, we included 405 patients with HF aged ≥65 years (mean age, 78.6 ± 7.5 years; 50% women). DPI was estimated from consumption over three consecutive days before discharge and normalized relative to the ideal body weight [IBW, 22 kg/m² × height (m)²]. The primary outcome was a composite of all-cause mortality and HF-related readmission withi
