Index of microvascular resistance after early conversion from calcineurin inhibitor to everolimus in heart transplantation: A sub-study to a 1-year randomized trial

In this prospective, open, randomized study comparing early CNI withdrawal with mammalian target of rapamycin inhibitors immunosuppression during the first year after HTx, early transition from CNI-based immunosuppression to EVR-based treatment did not result in differences in microvascular function as assessed by the IMR.
