Interventional - Device
The objective of the PIAAF Family Practice study was to finnd Atrial Fibrillation (AF) among patients 65 years of age or older, a family practice based screening program that will be implemented using three simple methods: manual pulse check; single lead handheld ECG; and blood pressure machine with automated AF detection algorithms.
Sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of each screening test in the Family Practice setting.
Cost effectiveness of screening, OAC prescription rates, risk factors, and user feedback from the screening tools.
Co-Principal Investigators, with Jeff Healey of PHRI, were:

2015 - 2016
Jeff Healey is a Senior Scientist in the Arrhythmia and Heart Failure research program at PHRI, an Associate Professor, Medicine, McMaster University, and Director of Arrhythmia Services at Hamilton Health Sciences. His research involves conducting RCTs and large registries in the fields of atrial fibrillation and cardiac devices. He was the lead author of the SIMPLE trial, published in the Lancet in 2015, which demonstrated that implantable defibrillators could be safely inserted without performing intra-operative defibrillation testing.
He was the lead author of the ASSERT trial, published in New England Journal of Medicine in 2012, demonstrating the increased stroke risk associated with sub-clinical atrial fibrillation detected by pacemakers. Thomson-Reuters recognized ASSERT as the 38th most-cited scientific publication in 2012 (#16 in Medicine).
He was principal investigator and chair of the Canadian Stroke Prevention Intervention Network (CSPIN), a ten-year network grant funded by the Canadian Institutes of Health Research, The Heart and Stroke Foundation of Canada and Industry. He is the past co-chair of the Canadian Cardiovascular Society’s Atrial Fibrillation Guidelines Committee. Jeff has published more than 185 manuscripts.
Study Team Specialist
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.
After years as Associate Program Manager for the Heart Failure and Arrhythmia Program, managing networks such as C-SPIN, and on the ACT COVI-19 research program, Heather was made Study Team Specialist in 2021, to provide regulatory, country and site management expertise to the studies in the Global Health research team. She has as a Master’s degree in Medical Sciences from McMaster University.
