Impact of atrial fibrillation status on clinical outcomes in patients admitted with heart failure.

ABSTRACT:

Background

Few studies comprehensively examine the association of atrial fibrillation (AF) status with rehospitalisation for adverse clinical outcomes in heart failure (HF) patients.

Methods

Patients admitted with a primary diagnosis of HF between 1-July-2003 and 31-March-2021 were identified from the Australian New South Wales Admission-Patient-Data-Collection database and stratified by AF status (no-AF vs new-AF vs prior-AF) (end-of-follow-up: 31-March-2022). Multivariable Cox regression and Fine-Gray competing risk methods were used to assess the association of AF status with risk of MACE/all-cause mortality and rehospitalisation for non-fatal outcomes respectively. MACE was defined as all-cause mortality, admission for myocardial infarction, ischemic stroke, HF or corona
