Long-term data on cardiovascular (CV) outcome of renal transplant recipients (RTR) on mTOR-i (mammalian Target Of Rapamycin-inhibitors) are scarce. In a sub-study of the MECANO trial we investigated changes in intima media thickness (IMT), CV risk profile, Major Adverse CV Events (MACE) and survival in RTR on a mTORi versus CNI based regimen. Patients (enrolled 361) were treated with (basiliximab) and triple IS (CsA-Cyclosporine A-(C), MPS (M), prednisolone (P)). At M6 patients were randomized (n = 224) to the CsA group (C, P, N = 89), MPS group (M, P, N = 39) EVL group (Everolimus, P, N = 96). At week 2, M6 and M 24, IMT measurements of the Common Carotid Artery were performed. Cardiovascular risk factors were assessed at baseline, 6 and 24 months of follow-up. Seven years survival and MACE-free survival probability were calculated by the Cardiovascular Risk Calculator for RTR. After 7 years of follow-up, incidence of cardiovascular events and patient survival were assessed. Mean IMT at baseline (N = 192), was 0.64 ± 0.14 mm. At M6 (N = 158), 0.66 ± 0.15, M24 IMT was 0.68 ± 0.15 (N = 95). No significant differences between groups concerning IMT, true CV events and mortality, CV risk profile, predicted MACE/Mortality were found between mTORi and CNI-based regimen after 7 years of follow-up.
