Prevalence of Subclinical Atrial Fibrillation in Heart Failure Patients and Its Relationship With Hospital Readmission

Brief description of study

Multicentre, prospective cohort study in patients with a history of HF with preserved or reduced ejection fraction admitted to hospital with acutely decompensated HF. Eligible and consenting patients will be enrolled at 3 Hamilton, Ontario area hospitals and receive 28-day ECG monitoring implemented at the time of hospital discharge. Patients will be followed for a total of 1 year from hospital discharge.

Detailed Study Description

In patients discharged from hospital after an admission for acute heart failure (HF) decompensation, subclinical atrial fibrillation (AF) of 30 minutes or greater in duration is common (at least 15% of patients without prior AF) and is associated with increased risk of re-hospitalization within 30-days.

Study Objectives:

  1. To evaluate the prevalence of subclinical AF 30 minutes in duration in patients discharged from hospital following an admission for acute HF exacerbation and who have no known history of clinical AF.
  2. To examine the temporal association between subclinical AF 30 minutes in duration and 30-day hospital readmission for HF.
