Abstract

Introduction: End-stage renal disease is a major risk factor for cardiovascular morbidity and mortality, which can be partially eliminated by kidney transplantation. Systolic heart failure might be considered contraindication for kidney transplant, although some patients demonstrate myocardial recovery post-transplant. We aimed to identify and characterize the phenomenon of reverse myocardial remodeling in kidney transplanted patients. Methods: The study is a retrospective cohort of patients undergoing kidney transplants between 2016 and 2019 (n = 604) at Rabin Medical Center. Patients were assessed according to availability of two echocardiographic examinations: pre- and postkidney transplant. The change in estimated ejection fraction (EF) and possible predictors of myocardial recovery were examined. Results: Data of 293 patients was available for the final analysis. Eighty-one (28%) patients had a LVEF improvement equal to or above 5%, whereas 36 (12%) patients had a LVEF improvement of 10% or more post-transplantation. Twenty-five patients (8.5%) had moderate or severe systolic heart failure with LVEF reduced to 40% or less at baseline. 13 of them (52%) had a LVEF improvement of =5%, and 10 patients (40%) had an improvement of =10% in their EF. Cox regression analyses identified female gender as the only independent variable associated with LVEF improvement of at least 10%. Conclusion: Renal transplantation might lead to improved LV systolic function in some patients.
