Psychosocial, neuropsychological and neurological status in a sample of heart transplant recipients

Abstract

The sample for this psychosocial follow-up study was formed using the 71 surviving patients from a total of 100 who underwent heart transplantation up until March 1990 at Kiel University Hospital. Forty of these could be investigated comprehensively. The neurological investigation comprised EEG and auditory and visually evoked potentials. The psychological investigation started with several neuropsychological tests; additionally all patients were interviewed and they completed questionnaires concerning anxiety, depression, ways of coping, personality characteristics and life satisfaction. Within the entire sample, there were few indications for specific psychological impairment. The psychosocial status of the patients was not significantly related to the time which had elapsed since they underwent transplantation. There were few associations between neuropsychological and psychosocial data, and several indicators of early postoperative complications which are described in the literature (e.g., length of stay in the intensive care unit). Clinically relevant subgroups (formed on the basis of neuropsychological test results, anxiety and depression) did not differ in terms of these indicators. Nevertheless, a considerable proportion of the patients (25%) were characterized by having a higher level of affective and neuropsychological impairment. Although based upon retrospective investigations, the results of this follow-up generally correlate with those gained from Anglo-American countries. In interpreting the results one needs to consider the possible influence of premorbid personality characteristics as well as denial which may be typical for patients undergoing heart transplantation.
