In transplant recipients, calcineurin inhibitors (CNIs) are associated with adverse cardiac effects while mTOR inhibitors have been reported to be beneficial. We performed a randomized controlled trial (RCT) in de novo renal transplant recipients examining cardiac responses of everolimus vs. CNI. This was a substudy of the three-yr CENTRAL study, an RCT on safety and efficacy of early (week 7 post-engraftment) conversion from cyclosporine A (CsA) to everolimus vs. continued CsA. Thirty-nine recipients [median age 64 yr, (range 31-81)] completed echocardiographic evaluations at baseline, one, and three yr. After three yr, there was no difference between groups in left ventricle (LV) diastolic function, LV systolic function, LV morphology, and blood pressure response. We observed a relevant decrease in LV mass (CsA; 9.6%, p = 0.008, vs. everolimus; 7.0% reduction, p = 0.15), stabilized LV diastolic function, and a trend toward lower systolic blood pressure with 6 mmHg decrease in both arms (CsA, p = 0.08; everolimus, p = 0.14). Diastolic blood pressure was significantly reduced (8 mmHg decrease, p = 0.002) only in everolimus patients. After three-yr follow-up, no clinically relevant effect on cardiac function of an early conversion from CsA to an everolimus-based immunosuppressive regimen was detected in de novo renal transplant recipients.
