Association of frailty with in-hospital outcomes in elderly patients with heart failure.

Background: Frailty is prevalent in elderly patients with cardiovascular diseases. However, the association between frailty and in-hospital outcomes for elderly patients with heart failure and reduced ejection (HFrEF) remains unknown.

Aim: To evaluate the predictive efficacy of frailty, compared with pre-frailty, for adverse events in these patients.

Methods: Elderly patients (≥ 60 years) with HFrEF were assessed. Frailty was evaluated with the Fried phenotype criteria, and physical performance was evaluated based on handgrip strength and the short physical performance battery (SPPB). The composite incidence of adverse events, including all-cause death, multiple organ failure, cardiac shock, and malignant arrhythmia, during hospitalization was recorded.

Results: Overall, 252 elderly individuals with HFrEF [mean age: 69.4 ± 6.7 years, male: 169 (67.0%)] were included. One hundred and thirty-five (53.6%) patients were frail and 93 (36.9%) were pre-frail. Frail patients were older, more likely to be female, to have a lower blood pressure, and to present with left ventricular thrombosis ( all < 0.05). Frail patients with HFrEF had a higher incidence of in-hospital mortality (11.9% 4.3%, = 0.048). Multivariate analyses showed that female gender (OR = 0.422), aging (OR = 1.090), poor cardiac functional class (OR = 2.167), frailty (OR = 2.379), and lower handgrip strength (OR = 1.106) were independent predictors of in-hospital adverse events ( all < 0.05).

Conclusion: Frailty may be associated with poor in-hospital outcomes for elderly patients with HFrEF. The influence of frailty on long-term prognosis in these patients deserves further investigation.
