BACKGROUND: Significant coronary artery disease (CAD) is an exclusion criterion for lung transplantation at most centers. However, the impact of preoperative noncritical CAD (single or multivessel mild <30% or moderate 30% to 50% stenosis) on the outcomes of lung transplantation is unknown.

METHODS: A retrospective review of 268 adult patients who underwent lung transplantation between June 1998 and June 2003 at Barnes-Jewish Hospital, a tertiary care center affiliated with Washington University School of Medicine, was performed.

RESULTS: Two hundred ten patients had coronary angiography performed as part of their pretransplantation evaluation. Among these patients, 177 patients had no CAD, and 33 patients (mild, 16; moderate, 17) had noncritical CAD. Patients with noncritical CAD were older (59 versus 55 years, p < 0.001) and had a higher prevalence of diabetes (24% versus 9%, p = 0.014) and systemic hypertension (58% versus 36%, p = 0.004) than patients without CAD. There was no significant difference in the underlying lung disease, other comorbidities, type of lung transplantation performed, early postoperative complications, and hospital or late mortality between recipients with or without CAD. Among the patients with noncritical CAD, there was no hospital mortality and no late cardiac mortality. Three recipients with preoperative moderate CAD developed late ischemic cardiac events, and revascularization was performed in 2 of these recipients. Long-term survival was similar among recipients with or without preoperative CAD.

CONCLUSIONS: Preoperative noncritical (mild or moderate) CAD was not associated with increased perioperative morbidity or mortality, and it did not adversely affect short-term or long-term survival. Late ischemic events developed in 18% of the recipients with moderate CAD disease with no effect on mortality.
