Body Mass Index and Chronic Total Occlusion Percutaneous Coronary Intervention Outcomes: Is Overweight the New Normal?

J Invasive Cardiol. 2023 Mar;35(3):E126-E127. doi: 10.25270/jic/22.00033. Epub 2023 Jan 13.


Although high body mass index (BMI) is a known risk factor for the development of cardiovascular diseases, people who are overweight or obese often have better outcomes after cardiac procedures. Whether this "obesity paradox" is observed in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is unknown. Therefore, we examined the association of BMI with the outcomes of CTO-PCI in patients from the large, multicenter PROGRESS-CTO registry after stratifying patients into 3 BMI groups.

Keywords: BMI; chronic total occlusion; clinical outcomes; percutaneous coronary intervention.
