Key result
Preoperative chronic pulmonary diseases independently increased the risk of postoperative hypoxemia following coronary artery bypass grafting by over 8-fold (OR 8.531).

Preoperative chronic pulmonary disease, acute myocardial infarction, and diabetes are significant independent risk factors for developing postoperative hypoxemia after CABG.
No takes yet. Share an insight, caveat, or question.
May warrant preoperative pulmonary risk stratification in CABG; leaves open whether targeted interventions reduce hypoxemia.
Ji et al. (2008) conducted an observational in Coronary artery disease undergoing coronary artery bypass grafting (n=576). Preoperative chronic pulmonary diseases vs. Absence of preoperative chronic pulmonary diseases was evaluated on Postoperative hypoxemia (OR 8.531, 95% CI 3.136-23.210, p=<0.001). Preoperative chronic pulmonary diseases independently increased the risk of postoperative hypoxemia following coronary artery bypass grafting by over 8-fold (OR 8.531).
