Impact of body mass index on long-term mortality in women and men undergoing percutaneous coronary intervention for chronic total occlusion.

Background: The obesity paradox has been described in different patient populations. Data on the relation between obesity and outcomes in patients undergoing percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) are lacking. Therefore, long-term mortality in patients undergoing CTO PCI was assessed according to different body mass index (BMI) categories.

Long-Term Follow-Up of Patients With Previous Coronary Artery Bypass Grafting Undergoing Percutaneous Coronary Intervention for Chronic Total Occlusion.

Successful revascularization of chronic total occlusions (CTOs) has been associated with clinical benefit. Data on outcomes in patients with previous coronary artery bypass grafting (CABG) undergoing percutaneous coronary intervention (PCI) for CTO, however, are scarce. A total of 2,002 consecutive patients undergoing PCI for CTO from January 2005 to December 2013 were divided into patients with and without previous CABG, and outcomes were retrospectively assessed.
