description: Bariatric surgery was associated with 49 cardiovascular deaths among 2037 patients in the control group. The number of total first time (fatal or nonfatal) cardiovascular events (myocardial infarction or stroke, whichever came first) in the control group was 234 events among 2037 patients. Extrapolated from this data the outcome of Nonfatal myocardial infarction or stroke occurred in 188 out of 2037 patients in the control group.
