[Emotional status of patients on the waiting list for heart transplantation]

Psychological assessment of patients on the heart transplant waiting list: A single center experience

OBJECTIVE

To analyze the data of the psychological assessment, focusing attention on the quality of life and the psychological status of patients who are listed for heart transplant.

METHODS

All heart failure patients listed for heart transplant at the Cardiac Surgery Unit of Bari University, Italy, were evaluated from September to November 2023, by administering the Symptom Checklist-90-R (SCL-90-R) and the Short Form Health Survey 36 (SF-36).

RESULTS

Overall, 27 patients were studied. Mean age was 60 years, 88% were males. One third of the patients showed a clinically significant overall mental distress. The symptoms leading to domains such as somatization (55.55%), anxiety (40.74%) and depression (33.33%) were frequently observed. The majority of the population studied (96.30%) showed low levels of perceived physical health status, while 59,62% of them presented levels of perceived physical health status below normal ranges.

CONCLUSIONS

Heart transplant candidates show elements of overall mental distress and low quality of life related to physical health status.

Health behaviors contribute to quality of life in patients with advanced heart failure independent of psychological and medical patient characteristics

BACKGROUND

Little is known about the contribution of health behaviors to quality of life (QoL) in heart transplant candidates. We examined physical activity, dietary habits, psychological, and medical patient characteristics as correlates of QoL among patients enrolled in the multisite Waiting for a New Heart Study.

METHOD

QoL (Minnesota Living with Heart Failure Questionnaire), demographic variables, psychological variables (e.g., depression, coping styles), and health behaviors (physical activity, dietary habits) were assessed in 318 patients (82% male, 53 ± 11 years) at the time of wait-listing and analyzed in 312 patients (excluding six underweight patients). Eurotransplant provided BMI and medical variables to compute the Heart Failure Survival Score (HFSS). Hierarchical multiple regression models were used to assess the independent contribution of health behaviors to QoL.

RESULTS

The HFSS was unrelated to QoL. As expected, psychological characteristics (depression, anxiety, vigilant coping style) contributed to impaired QoL, accounting for 22.9, 35.9, and 12.9% of the variance in total, emotional, and physical QoL, respectively. Physical inactivity further impaired QoL (total: 4.1%, p < 0.001; physical: 7.4%, p < 0.001). Dietary habits typically considered as unhealthy (i.e., infrequent consumption of fruits/vegetables/legumes; frequent intake of foods high in saturated fats) were related to enhanced physical QoL, but only among the overweight and obese patients.

CONCLUSION

Lifestyle interventions to modify negative emotions and to increase physical activity could help to improve QoL in heart transplant candidates, regardless of their disease severity. The role of eating habits in QoL among obese and overweight patients needs further exploration.

Psychosocial and behavioural factors in heart transplant candidates – an overview

Mortality among heart transplant (HTX) candidates remains high. This review of the literature shows that psychosocial characteristics like depression, social isolation and coping strategies contribute to morbidity and mortality in heart failure (HF) patients, and may also be relevant to the prognosis of HTX candidates. Based on the research to date, physical activity favourably affects subjective and objective parameters not only in HF patients, but also in HTX candidates. Depression is prevalent among HTX candidates, especially in ischaemic patients, and seems to be related to earlier transplantation. Findings on the effects of depression on pretransplant mortality are conflicting. Not much is known concerning social isolation, coping, nutrition, or weight loss in this patient group. Identification of modifiable psychosocial and behavioural variables related to clinical status in this patient group is clearly needed and will aid the development of behavioural interventions to supplement medical therapies.

The relationship between depressive symptoms and anxiety and quality of life and functional capacity in heart transplant patients

OBJECTIVE

To establish the relationship between depressive symptoms and anxiety with both the quality of life and functional capacity of heart transplant patients.

METHODS

Thirty-four patients were included. Outcome measures were the Beck Depression Inventory (BDI), the State- Trait Anxiety Inventory (STAI), the Short Form 36 (SF36) and peak oxygen consumption (pVO2).

RESULTS

After the transplant there was a significant negative correlation between the BDI and most of subgroups on the SF36 (p<0.05). There were significant negative correlations found between the pVO2 and both the BDI and STAI-trait anxiety score (p<0.05). Statistically significant improvements were noted in all subgroups on the SF36 and all BDI scores after the transplant, in comparison to the pre-transplant period (p<0.05).

CONCLUSIONS

The functional capacity of a person affects the state of their depression and anxiety. We recommend participation in a cardiac rehabilitation program in the early stages of transplantation and believe that the quality of life, which has been shown to be related to the functional capacity and psychological symptoms, would benefit from this program.

Psychological well-being in adults transplanted in childhood

Few studies have explored the long-term psychological effects on young adults of childhood transplants. The aim of the present work was to examine psychological adaptation related to self-concept, self-esteem and subjective well-being in young adults who had undergone solid organ transplantation in childhood. Twenty-four adults transplanted in childhood participated in the study (13 of them received kidney transplants, five heart transplants and six liver transplants). Participants were of both sexes, aged 18-22, and were selected from three public hospitals in Madrid. The results reveal no differences in psychological adaptation according to the transplant type (kidney, heart, or liver), and a significant difference in negative affect between women and men (women present more negative affect than men). Hierarchical regression analysis, after controlling for possible confounding effects of demographic and clinical variables, showed the predictive power of self-esteem to explain positive affect (60% of the total variance). Furthermore, physical self-concept, health status and time on waiting list explain 71% of the negative affect variance. Our data suggest the importance of self-esteem for the positive affect, and the power of clinical variables for the negative affect in young adults transplanted in childhood.

Two-year follow-up of quality of life in patients referred for heart transplant

BACKGROUND

Assessment of physical and mental health has become one of the ultimate tests of health-related quality of life (HRQOL) for patients with advanced heart failure. Little is known, however, about the comparative effects of surgical or medical treatment on the HRQOL of these chronically ill patients over time.

METHODS

We examined 77 patients (74% of whom were male), aged 56.1 +/- 12.7 years who were referred for heart transplant evaluation at a single heart failure center to describe the effects of time and treatment status on changes in HRQOL scores (physical and mental health and depression) using the Short Form-12 and the Beck Depression Inventory at 2 time points during their illness trajectory. The 2 evaluations on average were 2 years apart (mean 24.5 +/- 2.8 months). All patients were evaluated at baseline, and 3 groups were identified at the time of the 2-year follow-up: transplant recipients (n = 17), transplant candidates (n = 13), and medically stable patients considered too well to receive a transplant (n = 47). Nonparametric statistics were used to analyze group differences in HRQOL scores. The significance level was set at a P value less than .05.

RESULTS

Demographic and HRQOL scores were not significantly different among the 3 groups at baseline. During follow-up, physical health and depression scores significantly improved over time in all patients, but changes in mental health were minimal. Group comparisons showed that although all patients continued to have low HRQOL scores at the time of follow-up evaluation, medically stable patients had higher mental health scores and less depressive symptoms than their counterparts.

CONCLUSION

Our results support the need for ongoing HRQOL assessment with an emphasis on timely recognition and treatment of psychologic distress throughout the heart failure illness trajectory. Heart transplant recipients and candidates equally need special attention and follow-up because they both seem to have emotional and psychologic repercussions.

Depression in patients with heart failure

BACKGROUND

Psychologic comorbidities, particularly depression, often accompany heart failure and add to the complexity of clinical management. We conducted a study to describe the prevalence of depression, the differences between patients with minimal versus mild to severe depression, and the correlates of depression in patients with heart failure.

METHODS AND RESULTS

Data were collected from 200 patients with symptoms of heart failure resulting from systolic dysfunction. Psychologic assessment included depression, perceived control, neuroticism, educational needs, and social support/network. Patients were, on average, 57.0 (+/-12.1) years old, male (168, 84.0%), and in New York Heart Association (NYHA) class II or III (n=140, 70.0%) with a mean ejection fraction of 25.5+/-6.4%. They had an average maximal oxygen uptake of 15.8 (+/-4.6) mL x kg x min and 6-minute walk distance of 1345.0 (+/-302.1) feet. Minimal depression was described by 105 (52.5%) patients, mild by 62 (31%), moderate by 30 (15%), and severe by 3 (1.5%). The significant differences between patients with minimal depression compared to mild to severe depression were NYHA class (chi2=14.05, P=.003), maximal oxygen uptake (t=2.62, P=.010), 6-minute walk distance (t=4.22, P < .001), beta-blocker therapy (chi2=15.21, P < .001), perceived control (t=7.93, P < .001), and neuroticism (t=-8.85, P < .001).

CONCLUSIONS

More than half the patients studied did not report experiencing significant depression. In those who did, both physical and psychosocial variables accounted for 48.6% of the variance. These findings warrant further research and indicate a need to test interventions aimed at enhancing perceived control, reducing neuroticism, and meeting educational needs to reduce depression in patients with heart failure.

Standardized Psychological Evaluation Pre- and Posttransplantation: A New Option

A multicenter study was undertaken involving three teams in Italy to obtain a homogeneous psychological evaluation of patients needing organ transplantations. After a preliminary formulation of a common questionnaire individualizing 22 items, yielding a final score from 0 to 44, 294 forms were analyzed for correlations between variables. The sample responses were related to individual variables as well as by cluster analysis to aggregate typical profiles. Clustering of variables was observed in three areas that showed two variables (no. 6, "ongoing psychotic disturbances" and no. 10 "drugs") to be separate. Area 1 ("psychopathology") highlights psychic disturbances, cognitive disorders, and unhealthy behavioral styles; area 2 ("anxia") correlates anxious symptoms to pretransplant examinations and waiting time; area 3 ("depression") ties personal emotional resources and affective factors. Cluster analysis of the sample identified four groups: Group 1 (16.6%) "at risk;" mean score 25.2 (range 16-31); Group 2 (21.7%) "intermediate-at risk," mean score 32 (range 25-38); Group 3 (29.6%) "intermediate-ideal," mean score 35.3 (range 26-40); and Group 4 (31.9%) "ideal candidate," mean score 40.7 (range 36-44). The two "intermediate" groups were studied for mean values for area 1; namely, a cut-off value of 1.78 constituted a better or worse prognostic factor to assign the patient to either Group 2 or 3. Using a uniform method of psychological evaluation before transplantation reduced single operator subjectivity, obtaining comparable results in different transplant centers and allowing planning interventions for at-risk patients.
