Key result
Bariatric surgery links to reduced MACE, mortality, recurrent MI, and new-onset HF in severe obesity.
Why the study?
Diet and exercise alone are inadequate for managing obesity, prompting the need to analyze the evolution and cardiovascular status of obese patients with increased cardiovascular risk undergoing bariatric surgery.
Does bariatric surgery improve cardiovascular outcomes and structural profile in obese patients with increased cardiovascular risk?
Does bariatric surgery improve cardiovascular outcomes and structural profile in obese patients with increased cardiovascular risk?
Bariatric surgery significantly improves BMI and cardiovascular risk factors, leading to notable refinements in cardiovascular structure and function and reduced mortality and MACE in severe obesity.
May support bariatric surgery for CV risk reduction in severe obesity; leaves open confirmation by randomized trials.
Background and Objectives: Up until now, behavioral interventions and pharmacological therapies were the main approach available for the management of obesity. Diet and exercise, when used as a singular therapeutic method, are inadequate for a successful outcome. Research shows promising results for the surgical treatment of obesity, especially in the area of bariatric surgery (BaS). The relevance of this study is the valuable analysis of the evolution of obese patients with increased cardiovascular risk. Materials and Methods: The patients eligible for BaS commonly suffer from multiple chronic conditions, including type 2 diabetes, obstructive sleep apnea, cardiovascular diseases, and non-alcoholic fatty liver disease. Additionally, obesity contributes to an increased probability of developing certain types of cancer, osteoarthritis, urinary incontinence, and chronic kidney disease. In this review, we focused especially on the cardiovascular status of obese patients who underwent bariatric procedures. Results: BaS has been found to be strongly associated with a reduced incidence of severe complications in individuals with a history of myocardial infarction (MI) and severe obesity. Specifically, this procedure is linked to a lower occurrence of major adverse cardiovascular events and a decrease in overall mortality. Also, BaS is correlated with a reduced risk of recurrent MI and the development of new-onset heart failure. Conclusions: The results of BaS involve a significant amelioration of the BMI, contributing to a considerable decrease in cardiovascular risk factors and to a notable refinement in the cardiovascular structure and function.

Toader et al. (2025) conducted a review in Obesity with increased cardiovascular risk. Bariatric surgery was evaluated on Cardiovascular status, major adverse cardiovascular events, and overall mortality. Bariatric surgery is associated with a reduced incidence of major adverse cardiovascular events, overall mortality, recurrent MI, and new-onset heart failure in patients with severe obesity.
