Overview

Obesity signals elevated perioperative morbidity and recurrent angina risk after CABG without raising mortality; supports risk stratification but leaves causal effects open.

Structured PICO

Does obesity increase operative mortality, perioperative morbidity, and recurrent angina in patients undergoing CABG surgery?

P
Population
500 patients undergoing coronary artery bypass graft (CABG) surgery between 1984 and 1987, consisting of 250 obese patients and 250 age- and sex-matched controls of normal body mass index (BMI).
I
Intervention
Obesity (obese body mass index)
C
Comparator
Normal body mass index (BMI)
O
Outcome
Operative mortality and perioperative morbidityhard clinical

In patients undergoing CABG, obesity does not increase operative mortality but is an independent risk factor for perioperative morbidity and long-term recurrent angina.
