Abstract

BACKGROUND:

Significant coronary artery disease (CAD) has been a contraindication for listing patients for lung transplantation. We hypothesize that coronary risk stratification can help identify a sub-set of patients who need additional diagnostic tools and intervention.

METHODS:

We performed a retrospective review of 72 consecutive patients who underwent lung transplantation at our institution from 1995 to 2000. Further, a review of patients who are currently listed for transplantation yielded 48 patients. We then identified the various risk factors for CAD, the diagnostic tools used, and pre-operative intervention. Risk factors identified included smoking history, diabetes, hypertension, hypercholesterolemia, CAD, congestive heart failure, age >50, and arrhythmias. Based on these risk factors, the patients were then classified into 2 groups: low risk (< or =1 risk factors) and high risk (> or =2 risk factors). We identified the patients in each group who underwent coronary angiography (CA), those with angiographic evidence of CAD, and those who received pre-operative intervention.

RESULTS:

Of the 72 patients who underwent lung transplantation, 48 were identified as at high risk for CAD. Of these, 5 patients had CAD diagnosed before surgery using CA, and 1 patient received pre-operative intervention. Of the 48 patients currently on the lung transplant list, we identified 28 patients as high risk for CAD, 12 of whom were noted to have CA, and 2 of whom received pre-operative intervention.

CONCLUSIONS:

Although CAD was once a contraindication for lung transplantation, pre-operative risk stratification allows identification of CAD with CA in a high-risk group. We believe that by using appropriate pre-operative cardiac intervention, patients with severe CAD could successfully undergo lung transplantation.
