Answer

Before performing coronary artery bypass grafting (CABG), clinicians should carefully examine the patient’s medical history for factors that might predispose to complications, such as the following:

  • Recent myocardial infarction (MI)

  • Previous cardiac surgery or chest radiation

  • Conditions predisposing to bleeding

  • Renal dysfunction

  • Cerebrovascular disease including carotid bruits and transient ischemic attack (TIA)

  • Electrolyte disturbances that might predispose the patient to dysrhythmias

  • Infection including urinary tract infection, skin infections, and dental abscesses

  • Respiratory function including the presence of chronic obstructive pulmonary disease or infection [3]

The Euroscore is one of several scoring systems used to predict CABG mortality. Results can be rendered logistically or as a simple score, which can be calculated by using the Euroscore interactive calculator. [4]
