Risk factors which can affect the outcome of CABG

CABG risk factors (which can affect the outcome)

CABG risk factors – those conditions which can affect the outcome of Coronary Artery Bypass Grafting, can be listed as follows:

  1. Age and gender: advanced age and female gender have less favourable outcome.

  2. Previous cardiovascular events: prior cardiovascular surgery, interventions, myocardial infarction, stroke or transient ischemic attacks.

  3. Cardiovascular variables: left ventricular function, hypertension, cardiac arrhythmias.

  4. Diabetes mellitus, chronic renal disease, chronic obstructive pulmonary disease.

  5. Complexity of disease: number of vessels involved, severity of associated valvular stenosis or regurgitation and endocarditis if any.

  6. Hemodynamic status and urgency of surgery.

  7. Pulmonary hypertension, previous chest radiation, liver disease and frailty. Frailty is a newly recognized negative predictor of outcome after any surgery.
