Obesity paradox disappears in coronary artery bypass graft patients during 20-year follow-up.

Aims: Although obesity is a risk factor for coronary heart disease (CHD), it might be associated with a favourable prognosis in patients with CHD. The aim of the study was to evaluate this so called 'obesity paradox' during a follow-up period of 20 years in patients who had undergone coronary artery bypass grafting (CABG).

Methods And Results: The study population consisted of 922 CHD patients who had undergone CABG between 1993 and 1994.
