Risk factors which can affect the outcome of CABG
|Risk factors which can affect the outcome of CABG
Risk factors which can affect the outcome of Coronary Artery Bypass Grafting (CABG), can be listed as follows:
-
Age and gender: advanced age and female gender have less favourable outcome.
-
Previous cardiovascular events: prior cardiovascular surgery, interventions, myocardial infarction, stroke or transient ischemic attacks.
-
Cardiovascular variables: left ventricular function, hypertension, cardiac arrhythmias.
-
Diabetes mellitus, chronic renal disease, chronic obstructive pulmonary disease.
-
Complexity of disease: number of vessels involved, severity of associated valvular stenosis or regurgitation and endocarditis if any.
-
Hemodynamic status and urgency of surgery.
-
Pulmonary hypertension, previous chest radiation, liver disease and frailty. Frailty is a newly recognized negative predictor of outcome after any surgery.
