No decline in the risk of heart failure after incident atrial fibrillation: A community study assessing trends overall and by ejection fraction.

ABSTRACT:

Background

Patients with atrial fibrillation (AF) experience an increased risk of heart failure (HF). However, data are lacking on current trends in the risk of HF after AF.

Objective

The purpose of this study was to describe the temporal trends in HF occurrence after AF in a community cohort of patients with incident AF from 2000 to 2013.

Methods

Cox regression was used to examine the association of year of AF diagnosis with HF and the predictors of developing HF after AF.

Results

Among 3491 AF patients without prior HF, 750 (21%) developed incident HF over mean follow-up of 3.7 years. Among those with an echocardiogram, 422 (61%) had HF with preserved ejection fraction (HFpEF), and 270 (39%) had HF with reduced ejection fraction (HFrEF). After adjusting for d
