European Heart Journal, 42(S1), https://doi.org/10.1093/eurheartj/ehab724.1350

Background
Patients presenting to primary care with chest pain are often not given a cause. Patients with such unattributed chest pain have an increased risk of future cardiovascular disease (CVD) compared to patients with diagnosed non-coronary che...

Little is known about frailty amongst patients hospitalized with heart failure (HF) on a national level.

Methods:
We conducted a retrospective cohort study of patients admitted to hospital for HF in the United States. We examined how... Read More about The Hospital Frailty Risk Score and its association with in-hospital mortality, cost, length of stay and discharge location in patients with heart failure.
