Background: In 5-10% of HTX significant coronary artery sclerosis is transmitted. This study evaluates the impact of donor-transmitted coronary artery sclerosis (DCAS) on quality of life (QOL) and quality-adjusted life years (QALY) after transplantation.
Methods: In 1253 consecutive transplantations single-vessel DCAS was found in 53 patients (DCAS1 group) and double- or triple-vessel DCAS in 26 patients (DCAS2/3 group). Health-related QOL was analyzed by the “Short-Term Inventory 36 Health Survey” (SF-36) scale and QALY were calculated. Patients without DCAS, who were matched for sex, age, indication and time after transplantation, served as controls (NDCAS).
Results: Thirty-day mortality in groups NDCAS, DCAS1 and DCAS2/3 was 12.2%, 13.2% and 61.5%, respectively. However, beyond the first year the annual decrease in all groups was comparable (5.4%/year, 4.3%/year, and 5.0%/year). The SF-36 questionnaire showed no significant differences between the groups in the long-term survival. Quality-adjusted life years were comparable in groups NDCAS (8.0 QALY) and DCAS1 (8.5 QALY) but worse in DCAS2/3 (2.2 QALY).
Conclusions: DCAS represents a risk for early graft failure but impairs neither long-term survival thereafter nor quality of life (QOL). Donor screening by angiography seems to be a good investment to avoid the loss of about 6 quality-adjusted life years (QALY) by transmitted coronary atherosclerosis.
