Core Tip

Core Tip: Hyperkalemia is a potentially life-threatening complication of heart transplantation. Recipients of heart transplant are susceptible to hyperkalemia via multiple mechanisms both during transplantation, as well as in the pre- and post-transplant periods. Hyperkalemia has been well studied in kidney and liver transplantation, however data is limited regarding the incidence, causes, management, and prevention in heart transplant recipients.
