Study Summary

The primary objective of this study is to evaluate if, in patients with severe obesity (body mass index (BMI) ≥35 kg/m2) and high-risk cardiovascular disease (CVD), bariatric surgery compared to medical weight management (MWM) safely reduces the risk of major cardiovascular events. The cost-effectiveness of bariatric surgery will also be examined. Separate sub-studies will be performed to examine the relationship between bariatric surgery and mental health, cardiac structure and function, genomics, proteomics and metabolomics.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
