  1. aincludes patients with ≥1 isolated CABG surgeries; excludes patients with incidental valve surgery .
  2. bincludes patients with ≥1 on-pump procedure prior to incident cancer. Less than 0.2% of patients also had an off-pump procedure.
  3. celective: procedure deferred without increased risk of compromised cardiac outcome; urgent: not elective/emergent, required during same hospitalization to minimize chance of further clinical deterioration, worsening/sudden chest pain, congestive heart failure, acute myocardial infarction (AMI), anatomy, IABP, unstable angina with IV nitroglycerin or rest angina; emergent: ischemic dysfunction (ongoing ischemia including rest angina despite maximal medical therapy (medical and/or IABP), MI within 24 hours before surgery, or pulmonary edema requiring intubation), mechanical dysfunction (shock with or without circulatory support); emergent salvage: CPR enrout to the operating room or prior to anesthesia induction.
  4. Baseline characteristics were assessed at the time of the first open-heart surgery.
  5. %= n/N patients where n=frequency count in each category and N=total number of subjects.
  6. Due to rounding, sum of all percentages may equal 100%.
  7. CABG= coronary artery bypass graft, CPB=cardiopulmonary bypass (or “pump” procedure).
