  • Title: Regression of left ventricular hypertrophy in kidney transplant recipients: the potential role for inhibition of mammalian target of rapamycin.
    Author: Paoletti E, Cannella G.
    Journal: Transplant Proc; 2010 Nov; 42(9 Suppl):S41-3. PubMed ID: 21095451.
    Abstract:
    Left ventricular hypertrophy (LVH) contributes to elevated cardiac mortality with graft function in renal transplant recipients. Antihypertensive therapy, and especially angiotensin-converting enzyme (ACE) inhibitors, proved to be effective in regressing the LVH of renal transplant recipients, at least in part by interacting with immunosuppressive agents, thus raising the possibility that immunosuppressive therapy might affect changes in the left ventricular mass (LVM) of recipients. This review mainly focuses on the potential role of mammalian target of rapamycin (mTOR) inhibition to regress cardiac hypertrophy in both experimental models and in the clinical setting. We comment on the results of experimental studies conducted on animal models, which showed regression of cardiac hypertrophy by sirolimus (SRL). We also discuss clinical studies that show that conversion from calcineurin inhibitors to SRL is effective to achieve regression of LVH in both kidney and cardiac transplant recipients, mainly by reducing the true left ventricular wall hypertrophy.
