Improved survival after obesity operation in patients with previous myocardial infarction

(Karolinska Institutet) Researchers at Karolinska Institutet and Danderyd Hospital in Sweden have studied the risk of additional myocardial infarctions and early death in severely obese patients who undergo metabolic surgery following a myocardial event. The registry study covering 1,018 individuals shows a lower risk of additional myocardial infarctions and improved survival that cannot be simply attributed to the loss of weight. The study is published in the journal Circulation.
