William McIntyre

PHRI Investigator, William McIntyre received the 2023 Canadian Cardiovascular Society (CCS) Young Investigator Award at the annual Canadian Cardiovascular Congress (CCC) meeting hosted by CCS.

This recognition took place during the event held from October 25th to 29th in Montreal, Canada, where McIntyre presented his research findings on “Atrial Fibrillation Recurrence in Patients With Transient New-Onset Atrial Fibrillation Detected During Hospitalization for Noncardiac Surgery or Medical Illness,” published in the Annals of Internal Medicine.

McIntyre received recognition for his research on Atrial Fibrillation Occurring Transiently with Stress (AFOTS). The study investigates patients who develop new-onset atrial fibrillation (AF) during hospitalization for non-cardiac surgery or medical illness. It revealed a significant 1-year AF recurrence rate of 33.1% in these patients compared to a much lower 5.0% in a matched control group. This emphasizes that AF detected during hospitalization is frequently not reversible.

The Young Investigator Award was created in 1970 and is presented to a young investigator whose clinical or basic science activities are in the area of cardiovascular disease.

McIntyre is an Assistant Professor of Cardiology with McMaster University’s Department of Medicine, a cardiologist at Hamilton Health Sciences, and an Investigator in the Arrhythmia and Heart Failure research program at PHRI. McIntyre has an extensive publication history, with more than 150 peer-reviewed articles to his name. His research focus encompasses areas such as atrial fibrillation, including screening, detection, and cardioversion, as well as cardiac devices and methodologies in randomized clinical trials.

Notably, in 2018, McIntyre was recognized with the CCS Trainee Excellence in Education Award. He has also received fellowship awards from CIHR and the Canadian Stroke Prevention Intervention Network (C-SPIN), in addition to research grants from the Canadian Cardiovascular Society (CCS) Atrial Fibrillation Awards Program and the Heart and Stroke Foundation of Canada.
