The Obesity Paradox, Heart Surgery, and Blood Transfusion

Historically, there has not been a great understanding about the “obesity paradox,” which suggests that overweight and obese patients may have better outcomes than normal weight patients who undergo cardiac bypass surgery. Our newly published research confirms that while overweight and mildly obese patients do experience less blood transfusion and post-surgical bleeding than patients of normal weight, much of the observed reduction in transfusion rates in obese patients can be accounted for by other known confounds. The lack of linear effect of increasing BMI on blood transfusion risk is a novel finding and warrants additional research.

The full, peer-reviewed research is now available in the journal, Perfusion. An abstract of the findings was first presented at the 37th Annual Meeting of the American Academy of Cardiovascular Perfusion (AACP) in February 2016.
