Relationship Between Body Mass Index and Left Main Disease: The Obesity Paradox

Prognostic impact of body mass index in patients undergoing coronary artery bypass surgery

“…The finding was consistent with the data of Shirzad et al , who also showed a significant relationship with higher BMI and lower prevalence of left main disease in a population of 15 550 candidates for CABG 17. This indicated that obese patients were more likely to seek medical advice or be referred for CABG in earlier stages of CAD when they were younger.…”

Effect of Body Mass Index on Outcome in Patients With Suspected Coronary Artery Disease Referred for Stress Echocardiography

“…23 This may explain the lower CAD burden and lower prevalence of left main or triple vessel disease in obese patients undergoing coronary angiography and coronary artery bypass graft. 23,24 Interestingly, a more recent study of obese patients referred for coronary computed tomographic angiography without known CAD found that higher BMI had higher CAD risk factor burden, plaque burden, and risk for allcause mortality. 25 There was no specific explanation for these contrasting findings compared with multiple previous studies.…”

The impact of obesity on early mortality after coronary artery bypass grafting

“…The obesity paradox does appear to exist for high BMI patients with established CAD in whom prognosis appears to be generally equal-to or even superior to low or normal BMI patients 35,36 . This paradox needs to be further evaluated and outcome integrated into modern risk scoring systems.…”
