Changes in anxiety and depression over 2 years in medically stable patients after myocardial infarction and their spouses in the Home Automatic External Defibrillator Trial (HAT): a longitudinal observational study.

OBJECTIVE: To compare the long-term effects of cardiopulmonary resuscitation (CPR) training and CPR/automatic external defibrillator (AED) training on anxiety and depression of patients who were medically stable after myocardial infarction (MI) and of their spouses/companions. DESIGN: Longitudinal. PARTICIPANTS: Post-MI patients (N=460) and their spouses/companions from the Home Automatic External Defibrillator Trial. MAIN OUTCOME MEASURES: Depression (Beck Depression Inventory-II scores) and anxiety (State Trait Anxiety Inventory scores). RESULTS: At study entry, 25% of the patients and 15% of their spouses were depressed and 21% of the patients and 19% of the spouses were anxious. The prevalence of depression and anxiety did not change over time in the patients or their spouses. Average depression and anxiety decreased for patients but not for spouses. An intervention group did not contribute significantly to these changes. Psychological distress, indicated by depression or anxiety of the spouse or the patient, occurred in 191 couples. Among psychologically distressed patients (N=128), depression and anxiety decreased over time; the intervention group did not contribute to these changes. The reduction in anxiety among male patients was greater than in female patients (p=0.012, 95% CI 0.002 to 0.018). Among psychologically distressed spouses (N=118), depression decreased over time independently of the intervention. Changes in spouse anxiety depended on the intervention group (p=0.012, 95% CI 0.001 to 0.012); anxiety decreased significantly in the CPR and remained high in the CPR/AED group. CONCLUSION: There was no evidence that home AEDs caused psychological distress among patients. Even among those who were psychologically distressed when they were assigned to receive either CPR training or CPR/AEDs, home AEDs did not influence changes in patients' depression or anxiety or spouses' depression in comparison with CPR training. Among psychologically distressed spouses, AEDs may keep anxiety higher than it would be otherwise. Interventions to reduce anxiety of spouses who are psychologically distressed may be indicated when their partners receive an AED.

Collaboration between civilian and military healthcare professionals: a better way for planning, preparing, and responding to all hazard domestic events.

Collaboration is used by the US National Security Council as a means to integrate inter-federal government agencies during planning and execution of common goals towards unified, national security. The concept of collaboration has benefits in the healthcare system by building trust, sharing resources, and reducing costs. The current terrorist threats have made collaborative medical training between military and civilian agencies crucial. This review summarizes the long and rich history of collaboration between civilians and the military in various countries and provides support for the continuation and improvement of collaborative efforts. Through collaboration, advances in the treatment of injuries have been realized, deaths have been reduced, and significant strides in the betterment of the Emergency Medical System have been achieved. This review promotes collaborative medical training between military and civilian medical professionals and provides recommendations for the future based on medical collaboration.

Changes in psychosocial distress in outpatients with heart failure with implantable cardioverter defibrillators.

Patients given implantable cardioverter defibrillators (ICDs) after arrhythmic events or sudden cardiac arrest (SCA) experience psychosocial distress. ICDs now are inserted for the primary prevention of SCA in patients with heart failure; the psychosocial impact of ICDs on patients with heart failure is unknown. Changes in psychosocial status in these ICD recipients were examined. ICD recipients (n = 57) completed depression, anxiety, and social support inventories every 6 months for up to 2 years. Initially, 35% of recipients were depressed and 45% of recipients were anxious. In linear mixed models, depression decreased over time overall but increased in those who experienced ICD shocks. Anxiety decreased in New York Heart Association class III ICD recipients but not in class II ICD recipients. Decreases in social support were related to age: the younger the patient the greater the decrease. A significant proportion of ICD recipients were depressed or anxious, or had diminished social support even after 2 years. Investigation of strategies to improve ICD recipients' psychosocial status is warranted.

Relationship of depression, anxiety, and social isolation to chronic heart failure outpatient mortality.

OBJECTIVES: The Psychosocial Factors Outcome Study (PFOS) investigated the prevalence of depression and anxiety and the relationship of psychosocial factors to mortality in outpatients with heart failure (HF). BACKGROUND: Considerable evidence links psychosocial factors to coronary heart disease mortality and sudden cardiac death (SCD). The contribution of psychosocial factors independent of disease severity to HF outpatient mortality is not well elucidated. METHODS: Patients (N = 153) from 20 Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) sites participated in the PFOS. SCD-HeFT provided demographic, medical history, and cardiac data. Participants completed questionnaires to assess psychosocial status at PFOS entry. RESULTS: Depression and anxiety were common in HF outpatients (36% Beck Depression Inventory-II > or = 13; 45% State Trait Anxiety Inventory > or = 40). Depression, anxiety, and social support amount did not differ in the SCD-HeFT treatment groups: implantable cardioverter defibrillator, amiodarone, and placebo medication. Fifteen (9.8%) patients died during mean follow-up at 23.6 months (SD = 8.2). In Cox regression controlling for treatment, depression, anxiety, and social isolation separately predicted mortality; perceived HF-specific functional status did not. Depression (ln) [P = .04, hazard ratio (HR) = 1.81] and social isolation (P = .04, HR = 2.25), but not anxiety, predicted mortality independent of demographics, clinical predictors, and treatment. When simultaneously including significant demographic, clinical, and psychosocial predictors and treatment groups, depression (ln) (P = .022, HR = 2.2) and social isolation (P = .094, HR = 1.75) predicted mortality. All-cause mortality was 12% for depressed patients and 9% for others. CONCLUSION: This study finds a high prevalence of anxiety and confirms the high prevalence of depression in the HF outpatient population. Depression and social isolation predicted mortality independent of demographic and clinical status in HF outpatients.
