Although conversion from calcineurin inhibitors to mammalian target of rapamycin inhibitors proved to be effective in regressing left ventricular hypertrophy (LVH) in renal transplant recipients (RTRs) with chronic allograft dysfunction, there are currently no reports of randomized trials on this issue involving de novo RTRs administered everolimus (EVL).


This randomized, open-label, controlled trial evaluated the effect of EVL on the left ventricular mass index (LVMi) of 30 nondiabetic RTRs (21 men; age 28–65 years). Ten were allocated to EVL plus reduced-exposure cyclosporine A (CsA), and 20 to standard dose CsA. LVMi was assessed by echocardiography both at baseline and 1 year later. Blood pressure (BP), hemoglobin, serum creatinine, lipids, trough levels of immunosuppressive drugs, and daily proteinuria were also evaluated twice monthly. Antihypertensive therapy that did not include renin-angiotensin system blockers was administered to achieve BP less than or equal to 130/80 mm Hg.


Changes in BP were similar in the two groups (between group difference 1.2±5.7 mm Hg, P=0.84 for systolic, and −1.5±3.7, P=0.69, for diastolic BP), whereas LVMi significantly decreased in the EVL group alone (between group difference 9.2±3.1 g/m2.7, P=0.005), due to a reduction in both the interventricular septum and the left ventricular posterior wall thickness. EVL therapy together with baseline LVMi were the only significant predictors of LVH regression according to a multivariate model that explained 49% of the total LVMi variance (P=0.0015).


An immunosuppressive regimen consisting of EVL plus reduced exposure CsA proved to be effective in regressing LVH in RTRs regardless of BP, mainly by reducing left ventricular wall thickness.
