Dr. Gladstone is interested in pragmatic, clinically relevant research that can be readily applied to practice to improve patient care and outcomes. He is principal investigator of national multicentre clinical trials aimed at optimizing outcomes for patients with stroke and transient ischemic attack (TIA). His research is funded by peer-reviewed grants from the Canadian Stroke Network and the Canadian Institutes of Health Research, among others. He has authored or co-authored more than 100 scientific publications spanning the spectrum of stroke care including stroke prevention, prehospital care, emergency treatment of ischemic and hemorrhagic stroke, transient ischemic attacks, cryptogenic stroke, atrial fibrillation, anticoagulant therapies, outcome measures in stroke recovery and neurorehabilitation. He completed his PhD through the Royal College Clinician-Scientist Training Program and his thesis earned the McNaughton national research award from the Canadian Neurological Society. He has held a Clinician-Scientist Award from the Heart and Stroke Foundation, and is the recipient of the Sunnybrook Hospital Young Investigator Award and the Early Researcher Award from the Ontario Ministry of Research and Innovation.
His major focus is clinical trials research aimed at improving primary and secondary stroke prevention through better detection and treatment of atrial fibrillation. He is principal investigator of EMBRACE, the largest study and first randomized controlled trial of prolonged, noninvasive cardiac rhythm monitoring for patients with cryptogenic stroke or TIA. The results of this trial, published in the New England Journal of Medicine, demonstrated the effectiveness of a new strategy that significantly improves the detection and treatment of this common but often silent stroke risk factor. As part of the Canadian Stroke Prevention Intervention Network, he is leading SCREEN-AF, a primary prevention screening trial that aims to develop a practical and cost-effective strategy to improve the early detection and treatment of atrial fibrillation in primary care patients aged 75 years and older.
He is principal investigator of the SPOTLIGHT study, a randomized trial testing an innovative image-guided emergency treatment protocol to reduce disability and improve recovery for patients with hemorrhagic stroke. He also directs projects within the Ontario Stroke Registry (formerly known as the Registry of the Canadian Stroke Network), one of the world’s largest stroke databases evaluating quality of care, safety issues and practice gaps in stroke management.
He has been working to develop Sunnybrook as a premier regional stroke centre and has been site principal investigator for several national and international clinical trials of new treatments for acute ischemic and hemorrhagic stroke.He is a top-rated teacher and has delivered more than 400 presentations to educate health care professionals about best practices in stroke care.
