We examined the long-term relationship of psychosocial risk and health behaviors on clinical events in patients awaiting heart transplantation (HTx). Psychosocial characteristics (e.g., depression), health behaviors (e.g., dietary habits, smoking), medical factors (e.g., creatinine), and demographics (e.g., age, sex) were collected at the time of listing in 318 patients (82% male, mean age = 53 years) enrolled in the Waiting for a New Heart Study. Clinical events were death/delisting due to deterioration, high-urgency status transplantation (HU-HTx), elective transplantation, and delisting due to clinical improvement. Within 7 years of follow-up, 92 patients died or were delisted due to deterioration, 121 received HU-HTx, 43 received elective transplantation, and 39 were delisted due to improvement. Adjusting for demographic and medical characteristics, the results indicated that frequent consumption of healthy foods (i.e., foods high in unsaturated fats) and being physically active increased the likelihood of delisting due improvement, while smoking and depressive symptoms were related to death/delisting due to clinical deterioration while awaiting HTx. In conclusion, psychosocial and behavioral characteristics are clearly associated with clinical outcomes in this population. Interventions that target psychosocial risk, smoking, dietary habits, and physical activity may be beneficial for patients with advanced heart failure waiting for a cardiac transplant.
Background: We evaluated depression and social isolation assessed at time of waitlisting as predictors of survival in heart transplant (HTx) recipients. Methods and Results: Between 2005 and 2006, 318 adult HTx candidates were enrolled in the Waiting for a New Heart Study, and 164 received transplantation. Patients were followed until February 2013. Psychosocial characteristics were assessed by questionnaires. Eurotransplant provided medical data at waitlisting, transplantation dates, and donor characteristics; hospitals reported medical data at HTx and date of death after HTx. During a median followâ€up of 70 months (<1"93 months postâ€HTx), 56 (38%) of 148 transplanted patients with complete data died. Depression scores were unrelated to social isolation, and neither correlated with disease severity. Higher depression scores increased the risk of dying (hazard ratio=1.07, 95% confidence interval, 1.01, 1.15, P=0.032), which was moderated by social isolation scores (significant interaction term; hazard ratio = 0.985, 95% confidence interval, 0.973, 0.998; P=0.022). These findings were maintained in multivariate models controlling for covariates (P values 0.020"0.039). Actuarial 1â€year/5â€year survival was best for patients with low depression who were not socially isolated at waitlisting (86% after 1 year, 79% after 5 years). Survival of those who were either depressed, or socially isolated or both, was lower, especially 5 years posttransplant (56%, 60%, and 62%, respectively). Conclusions: Low depression in conjunction with social integration at time of waitlisting is related to enhanced chances for survival after HTx. Both factors should be considered for inclusion in standardized assessments and interventions for HTx candidates.

Monatelange Wartezeiten auf einen ambulanten Psychotherapieplatz sind der Regelfall im deutschen Gesundheitssystem. Die Veränderung der Symptombelastung der Patienten in der Wartezeit ist bislang allerdings kaum empirisch untersucht worden. In der vorliegenden Arbeit wurden an einer Stichprobe ambulanter Psychotherapiepatienten die Ausprägungen und Veränderungen der allgemeinen psychischen Symptombelastung während der durchschnittlich sechsmonatigen Wartezeit auf den Psychotherapieplatz untersucht. Zudem wurde überprüft, mit welchen Merkmalen die Symptombelastungen zum Zeitpunkt der Anmeldung zur Therapie und zum Zeitpunkt des Erstgesprächs sowie ihre Veränderungen in der Wartezeit zusammenhängen. Die dabei untersuchten Persönlichkeitsmerkmale wurden aus theoretischen Rahmenmodellen abgeleitet. Hierzu gehören die aktionale Entwicklungspsychologie, das handlungstheoretische Partialmodell der Persönlichkeit mit der darin eingeordneten Vertrauens-Trias und das Androgynie-Modell der psychischen Gesundheit. Nach einem direkten Veränderungskriterium zeigten 48 % der Patienten in der Wartezeit keine bedeutsame Veränderung, 29 % eine Verbesserung und 23 % eine Verschlechterung. Durch die bei der Anmeldung erfassten Persönlichkeitsmerkmale konnten Verbesserungen, Verschlechterungen und gleichbleibende Symptombelastungen in der Wartezeit anhand einer multinomialen logistischen Regressionsanalyse für 60 % der Patienten korrekt vorausgesagt werden. Eine traditionelle normative Geschlechtsrollen-Orientierung stellt einen negativen Prädiktor für eine Verbesserung dar. Soziales Vertrauen konnte Verschlechterungen negativ vorhersagen. Bei Hoffnungslosigkeit handelt es sich um einen marginal negativen Prädiktor für eine Verbesserung. Ein hoch ausgeprägtes Selbstkonzept eigener Fähigkeiten ist ein positiver Prädiktor für eine Verschlechterung. Hinsichtlich der soziodemografischen und störungsbezogenen Merkmale konnten das Alter, das Geschlecht und die Anzahl der Diagnosen die Veränderungen der Symptombelastung in der Wartezeit zu 54 % korrekt vorhersagen. Das Alter ist ein positiver Prädiktor für eine Verschlechterung. Weibliches Geschlecht und die Anzahl an Diagnosen sind negative Prädiktoren für eine Verbesserung. Darüber hinaus wurden differenzierte Zusammenhänge zwischen den Persönlichkeitsmerkmalen und der Symptombelastung exploratorisch untersucht.
