Abstract
Background Cardiovascular assessment is central to evaluation of liver transplant (LT) candidates. However, there is a lack of consensus on the diagnostic algorithm for screening for coronary artery disease (CAD), and the place for invasive coronary angiography (ICA) remains undefined. Methods We retrospectively analysed 1201 adults who underwent elective LT assessment over a 5-year period. For patients who underwent LT, survival data to 5 years post-LT was collected. Results ICA was performed in 259 (21.6%): 134 no CAD, 58 mild, 33 moderate, and 34 severe. Detection of CAD was associated with age (OR 1.08, P < 0.01), current smoking (OR 4.92, P < 0.01) and prior CAD (OR 8.93, P < 0.001). Poor performance on cardiopulmonary exercise test (CPET) was associated with age (OR 1.02, P < .05) and diabetes mellitus (OR 1.54, P < 0.05). 122 (10.2%) patients were declined due to severity of cardiovascular disease. 169/779 (21.7%) patients listed for LT had undergone ICA, and CAD was present in 73/169 (43.2%). The non-risk-adjusted all-cause post-LT 5-year survival was 82.6%, with no difference in survival in those with and without CAD on ICA. In patients with CAD, diabetes was associated with reduced survival (OR 3.78, P < 0.05). Conclusions Multi-modality cardiac evaluation is useful in high-risk patients undergoing LT assessment. ICA can be used with non-invasive assessments and risk factors to delineate candidacy. In selected patients with CAD, LT has been undertaken with comparable post-LT survival.
