(1) Cognitive assessment should be integrated into the follow-up of patients after heart transplantation. Bürker and co-workers examined the cognitive function of 37 patients three years after transplantation, of which about half received standard immunosuppressive therapy with the calcineurine inhibitor cyclosporine. The rest had been randomly assigned to experimental immunosuppression with everolimus and a much lower dose of cyclosporin, shown to retain renal function better and reduce calcification of the large blood vessels of the new heart. There was no difference in cognitive function between the two groups. Overall, 40% of patients had cognitive impairments such as attention, memory or language problems.
(2) Nearly 40% of long-term heart transplant survivors exhibit impaired test performance on several cognitive measures. All 37 patients included had survived for more than 16 years after transplantation, and they generally scored below population norms on cognitive parameters like precessing speed, executive functions, memory and language. 30 % qualified for mild cognitive impairement.
(3) Patients with clinical significant depression five years after heart transplantation have doubled risk of premature death. 141 heart transplant recipients were included in the study and followed for up to 20 years after transplantation.
