Risk Factors for Gastrointestinal Complications Following CABG Surgery

Purpose: Purpose: To identify risk fators for GI complications following a coronary artery bypass graft (CABG) surgery as reported by Rodriguez et al.

Description

Rodriguez et al identified risk factors for gastrointestinal (GI) complications following coronary artery bypass graft (CABG) surgery. The presence of gastrointestinal complications is associated with increased inpatient mortality, so can help identify patients who may benefit from more aggressive management. The authors are from Stanford University and the University of North Carolina at Chapel Hill.


 

Gastrointestinal complications following CABG include: GI bleeding, pancreatitis, ileus, diverticulitis, hepatic failure, mesenteric ischemia, and cholecystitis

 

Parameters:

(1) age

(2) need for hemodialysis (a surrogate for renal failure)

(3) use of an intraaortic balloon pump (IABP)

(4) concomitant valve procedure

(5) artery used for the bypass graft

where:

• The use of an internal mammary artery was found to be protective, which means use of another is a risk factor.

• An urgent surgery was also listed as a risk factor, but the odds ratio of 1.2 is fairly low.

 

total number of risk scores =

= SUM(points for all 5 parameters)

 

Interpretation:

• minimum number of risk factors: 0

• maximum number of risk factors: 5

• The higher the number of risk factors the greater the risk of a GI complication.
