Antithrombotic therapies are effective for prevention of cardiovascular (CV) events, but they cause bleeding. Emerging evidence indicates that extra-cranial bleeding is just as important as myocardial infarction as a marker of risk for subsequent non-fatal and fatal CV events, but this issue has not been prospectively studied.
If the association between bleeding and CV events is causal, prevention of bleeding, by targeting the risk factors, and prevention of the complications of bleeding, by targeting the causal pathways, could substantially reduce the burden of bleeding-related CV events.
The objectives of the INTERBLEED study are to determine, in patients with cardiovascular disease:
1. risk factors for gastrointestinal bleeding;
2. mechanisms linking gastrointestinal bleeding with risk of subsequent major adverse cardiovascular events;
3. impact of GI bleeding on functional outcomes.

John Eikelboom is Associate Professor in the Department of Medicine, McMaster University, and a haematologist in the Thrombosis Service, Hamilton General Hospital. He originally trained in Internal Medicine and Haematology in Perth, Australia and subsequently moved to Hamilton to take up a Tier II Canada Research Chair in Cardiovascular Medicine.
He has co-authored more than 350 articles in peer-reviewed journals. His current research, supported by the Canadian Institutes for Health Research, the Heart and Stroke Foundation and the National Health and Medical Research Council of Australia, focuses on the efficacy and safety of antithrombotic therapies, outcomes after blood transfusion and bleeding, and the mechanisms of variable response to antiplatelet drugs.
Jackie Bosch started working with Salim Yusuf in 1993, before PHRI was formally created, as she was completing her Masters in Clinical Epidemiology, with the intent to learn how to do clinical trials so she could run trials in post-stroke rehabilitation. Most recently, she has been a co-investigator on large trials in primary and secondary prevention of cardiovascular disease and diabetes, as well as understanding the causes of functional decline as well as developing simple, internationally applicable interventions to improve post-stroke disability.
She is Assistant Dean of the Occupational Therapy program, School of Rehabilitation Sciences, McMaster University, and has received awards such as the (McMaster) President’s Award for Outstanding Service, and the PHRI Award for Outstanding Contributions to Global Collaborations. She has more than 65 peer-reviewed publications.
Sumathy Rangarajan has been Program Director, Global Health, since 2016, preceded by many years’ service at PHRI in other roles. She oversees the PURE study team, as well as the INVICTUS rheumatic AF treatment trial, the CANPWR pediatric weight management registry, and others.
She holds both a Bachelor of Science Degree and a Master of Science degree from Pune University in India.
