Heart failure (HF) is the leading cause of hospitalization in patients older than 65 years of age. Following HF hospitalization approximately 25% of patients are readmitted within 1 month of discharge and more than 50% of patients are readmitted within 6 months.
Atrial fibrillation (AF) is a common comorbidity in patients with HF and it is a common cause of HF exacerbation. However, the majority of patients are in sinus rhythm when they present to hospital with acutely decompensated HF and the cause cannot be identified in 40-50% of patients.
We hypothesize that subclinical atrial fibrillation (SCAF) is highly prevalent in patients with HF and is an important cause of HF exacerbation and hospitalization. The proposed study is a non-intervention cohort study to determine the prevalence of SCAF in patients discharged after a hospitalization for HF and define its relationship to HF hospital readmission at 30 days.Download Presentation PDF
Multicentre, prospective cohort study
Jorge Wong is a cardiologist and cardiac electrophysiologist at Hamilton Health Sciences, as well as an investigator in the Arrhythmia and Heart Failure program at PHRI. His research interests focus primarily on the intersection between atrial fibrillation and heart failure, atrial fibrillation epidemiology and catheter ablation for atrial fibrillation. His current research program, PROTECT-HF, is examining the relationship between subclinical atrial fibrillation and heart failure re-hospitalization. Jorge holds research grants from the Heart and Stroke Foundation of Canada, the Canadian Cardiovascular Society, and Hamilton Health Sciences.
He obtained his MD at McMaster, followed by his internal medicine and cardiology training at the University of Western Ontario. He subsequently completed his clinical electrophysiology fellowship at the University of Calgary and at the Brigham and Women’s Hospital in Boston. He has a Master of Public Health degree from the Harvard School of Public Health, and is currently pursuing his PhD in Health Research Methods at McMaster.
Associate Program Manager
Heather Beresh has worked at PHRI since May 2002, largely devoted to managing global, multi-centre clinical trials of antithrombotic therapies in patients with atrial fibrillation (AF). She started as research coordinator for the ACTIVE study evaluating dual antiplatelet therapy and angiotensin receptor blockers in patients with AF, then continued with oversight of the AVERROES open label extension trial evaluating a novel oral anticoagulant in the same population, and ARTESiA evaluating anticoagulant therapy in patients with subclinical AF.
In addition, she has coordinated trials of ablation procedures versus anti-arrhythmic medications and trials evaluating screening strategies for AF. Heather also manages network collaborations, including the Canadian Stroke Prevention Intervention Network (CSPIN). She has as a Master’s degree in Medical Sciences from McMaster University.
