Patients with a high BMI had more comorbidities and were more likely to have had coronary artery bypass grafting than valve surgery. A total of 143 patients (6.7%) died during a median follow-up period of 30 months. The major causes of death were congestive heart failure (25.9%), myocardial infarction (14.7%), infection (23.8%) and cancer (13.9%). BMI had no association with long-term mortality, after adjusting for important confounders including the Charlson Comorbidity Index. BMI had a relatively linear relationship with the risk of new-onset atrial fibrillation (odds ratio 1.05 per point increment, 95% confidence interval 1.03 to 1.05) and venous thromboembolism (odds ratio 1.20, 95% confidence interval 1.14 to 1.26). BMI was the second most important predictor after age and accounted for 22% of the variability in the risk of atrial fibrillation. BMI had an inverse relationship with the risk of requiring allogeneic blood transfusion, postoperative intra-aortic balloon pump, or surgical re-exploration. In summary, BMI had differential associations with different short- and long-term outcomes after elective adult cardiac surgery. After adjusting for important confounders including the presence of cancers, we did not observe any \u2018obesity paradox\u2019 and patients with a high BMI were not associated with an increased probability of long-term survival.<\/jats:p>","DOI":"10.1177\/0310057x1304100502","type":"journal-article","created":{"date-parts":[[2019,1,14]],"date-time":"2019-01-14T17:42:16Z","timestamp":1547487736000},"page":"573-583","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":29,"title":["Differential Associations between Body Mass Index and Outcomes after Elective Adult Cardiac Surgery: A Linked Data Cohort Study"],"prefix":"10.1177","volume":"41","author":[{"given":"K.
