INTRODUCTION:In patients undergoing lung transplantation (LTx), the impact of pre-existing coronary artery disease (CAD) on long-term outcomes is not well understood. This study examines the outcomes of patients undergoing LTx with and without CAD.
METHODS: 655 consecutive patients that underwent LTx at a single center from 2008 thru 2012 were evaluated prospectively in a hospital based registry. All patients >45 years of age underwent pre-LTx catheterization per institutional protocol. Presence of CAD defined as prior CABG, stenting, myocardial infarction (MI) or stenosis >50% in major epicardial vessel.
RESULTS: Of the 655 patients, 158 (24%) were identified as having CAD. Demographics for with and without CAD are age(66.4 vs 58.1 years, p<0.001), female (19.6 vs 50.3%, p<0.001), median LAS score (41.56 vs 40.62, p=0.57), and double LTx (72.8 vs 89.2, p<0.001). In patients with CAD, 1.9% had prior MI, 13.9% had prior stenting, 46.2% had newly diagnosed stenosis >50%, and 30.4% had at prior CAD with residual stenosis of >50%. Forty-five patients underwent revascularization prior to LTx.
Figure 1a shows survival curves for patients with and without CAD. Figure 1b illustrates outcomes for patients that underwent revascularization were similar to those without CAD and worse outcomes for those without revascularization.
CONCLUSIONS: There is a trend towards worse outcomes in patients with CAD undergoing LTx but outcomes are improved in those who received pre-operative revascularization with stents. Further randomized studies are necessary in this cohort to examine the impact of moderate coronary disease and revascularization on outcomes.
