Dr. Jonathan Afilalo is a cardiologist and researcher at the Jewish General Hospital, and a tenured associate professor at McGill University. He holds a graduate degree in epidemiology from McGill University and level III training in advanced cardiac imaging from Harvard University. His research program is focused on the assessment and treatment of frailty to improve health-related outcomes and successful aging in older adults with cardiovascular disease. He led the first (JACC 2010) and largest (JAMA Cardiology 2016) studies on gait speed in cardiac surgery, and subsequently led the multi-national FRAILTY-AVR study (JACC 2017). He is currently conducting the PERFORM-TAVR trial on home-based exercise and nutrition in frail older adults undergoing transcatheter aortic valve replacement. These contributions were recognized by the Royal College Gold Medical for Research, Canadian Cardiovascular Society Young Investigator Award 2nd Prize, and American College of Cardiology Section Merit Award. Dr. Afilalo (@FrailtyMD) and his team have created digital platforms (frailtytool.com) and open source software (coreslicer.com) to promote knowledge translation in this sphere. Dr. Afilalo is founding director of Canada’s first fellowship program in geriatric cardiology. In addition, Dr. Afilalo is co-director of the Jewish General Hospital’s fellowship program in integrated cardiac imaging, and he has contributed to international guidelines in the fields of echocardiography and cardiovascular magnetic resonance imaging.
