Bio
Dr. Lonn is a Principal Investigator for both the Atherosclerosis Imaging and Cardiovascular Prevention programs at the Population Health Research Institute. After obtaining her medical degree from the Hebrew University in Jerusalem, Dr. Lonn completed clinical training in Internal Medicine, Cardiology and Advanced Imaging at the University of Toronto and research fellowships at the University of Toronto and at McMaster University, where she obtained also a Master of Science degree in Health Research Methodology. She is currently a Professor of Medicine in the Division of Cardiology at McMaster University. Dr. Lonn’s research interests are in clinical trials in cardiovascular prevention, understanding of the determinants of atherothrombotic cardiovascular diseases, including traditional and novel risk factors and ultrasound imaging in atherosclerosis. She has lead several large international trials and was a member of the International Steering Committee of additional landmark cardiovascular prevention trials. She directed the Vascular Research Ultrasound Laboratory at the Population health Research Institute for over 20 years and was the principal investigator of several large multicentre imaging studies in atherosclerosis. She served for many years on the Canadian Cardiovascular Society Council and Executive Committee and serves currently as Ontario Governor on the American College of Cardiology Board of Governors. Dr. Lonn has received research grants from the Medical Research Council of Canada, the Canadian Institutes of Health Research and the Heart and Stroke Foundation of Canada. She published over 220 peer reviewed articles, and 8 book chapters.
Research Interests
- Clinical trials in the primary and secondary prevention of cardiovascular diseases, vascular imaging in atherosclerosis, the study of traditional and emerging cardiovascular risk factors, cardiovascular epidemiology and the use of echocardiographic methods for the assessment of left ventricular mass and left ventricular systolic and diastolic function. Dr. Lonn was the principal investigator of several large international multicentre cardiovascular prevention trials and trials in atherosclerosis using carotid intima media thickness. Currently she is Co-Principal Investigator of the HOPE-3 trial and a member of the international Steering Committee of the COMPASS and TIPS-3 trials.
