Psychosocial recovery from a cardiac event: the influence of perceived control.
OBJECTIVE: To determine the relationship between patients' feelings of control at baseline and psychosocial recovery 6 months after their cardiac event. PATIENTS: One hundred seventy-six patients who had had myocardial infarction, had undergone coronary artery bypass or both. DESIGN: In this longitudinal, comparative survey patients with high perceptions of control were compared with those with low perceptions of control at baseline to determine differences in psychosocial recovery 6 months later. OUTCOME MEASURES: Psychosocial recovery was operationalized as anxiety, depression, and hostility (measured by Multiple Affect Adjective Checklist) and overall psychosocial adjustment to illness (measured by Psychosocial Adjustment to Illness Scale). RESULTS: Significant differences were seen in psychosocial recovery between patients with feelings of high control versus those with feelings of low control (p = 0.006). Patients with feelings of high control at baseline were less anxious (p = 0.002), less depressed (p = 0.001), less hostile (p = 0.02), and had better psychosocial adjustment (p = 0.009) at a 6-month follow-up than those with feelings of low control. CONCLUSION: Feelings of perceived control are important for psychosocial recovery after a cardiac event.

Women's decision to seek care for symptoms of acute myocardial infarction.
OBJECTIVE: To describe the psychosocial processes by which women make the decision to seek care for the symptoms of Acute Myocardial Infarction (AMI). DESIGN: The qualitative method of grounded theory was used to study the prehospital experience of women with symptoms of AMI. PARTICIPANTS: Sixteen women between the ages of 42 and 82 years who were hospitalized in a coronary care unit after AMI. RESULTS: The women delayed a median of 5.4 hours (range 1.5 to 144 hours). The psychosocial processes by which they made the decision to seek treatment after symptom onset were dynamic and multidimensional. The fundamental structure involved two core categories: (1) maintaining control, and (2) relinquishing control. Within these two core categories there were five subcategories: symptom awareness, perceived insignificance, self-treatment, perceived threat, and lay consultation. CONCLUSION: Although these women immediately recognized their symptoms as abnormal, they did not acknowledge their seriousness until after the use of a variety of coping mechanisms and self-treatment behaviors to reduce threat and maintain control over the situation. Interventions to reduce delay should focus on the issue of perceived loss of control during symptom onset and attempt to reduce the sense of threat by describing the benefits of seeking treatment early.

Sexual function in patients with advanced heart failure.
OBJECTIVES: To determine the effect of low ejection fraction on sexual function and the relation between alterations in sexual function and pertinent clinical, demographic, and psychosocial variables in patients with advanced heart failure. DESIGN: This study was descriptive and correlational in design. SETTING: The setting was an outpatient clinic of a university-affiliated hospital. SUBJECTS: Sixty-two male (82%) and female (18%) patients with advanced heart failure (New York Heart Association [NYHA] class III or IV) were studied. MEASURES: Exercise tolerance and symptom severity were assessed by the 6-minute walk and NYHA classification. Ejection fraction was measured by echocardiography. Alterations in the patients' emotional, social, and sexual function were assessed with the self-report version of the Psychosocial Adjustment to Illness Scale. RESULTS: Approximately three quarters of the patients reported a marked decrease in sexual interest and in the frequency of sexual relations caused by illness, with one quarter having ceased all sexual activity. Half the patients described having experienced marked reductions, after heart failure developed, in the pleasure or satisfaction they normally experienced from sex. Few patients had arguments with their spouses about sex or reported significant marital problems as a result of their illness. A significant relation was documented between patients' sexual function and the results of the 6-minute walk (r = 0.32, p < 0.005), as well as between sexual function and NYHA functional class (r = 0.21, p < 0.05). Sexual function was also related to the patient's social environment (r = 0.59, p < 0.001), psychologic distress (r = 0.38, p < 0.001), and domestic environment (r = 0.29, p < 0.05). No significant differences in sexual function were noted when patients were compared on the basis of differences in ejection fraction, medications, gender, or age. CONCLUSION: Advanced heart failure results in marked changes in libido and in the ability to perform sexually. These changes do not affect the marital relationship negatively, at least in the view of the patient. As patients' symptoms of heart failure become increasingly more severe, physicians and nurses need to counsel patients and their spouses about the changes they may experience in their sexual relationships. Attention needs to focus on ways to cope with the decreasing physical status that accompanies advanced heart failure to minimize negative changes in sexual functioning.

Hemodynamic adaptation to orthostatic stress after orthotopic heart transplantation.
OBJECTIVES: The purpose of this study was to compare the effects of orthostatic stress on cardiovascular stability in heart transplant recipients early and late after transplantation and in healthy controls. BACKGROUND: After transplantation, cardiac reinnervation is heterogeneous, with reports of sympathetic reinnervation after 5 months and parasympathetic reinnervation after 2 to 3 years. METHODS: Sixteen heart transplant recipients early (less than 5 months) after transplantation, 17 recipients late (1 year or more) after transplantation, and 16 matched healthy controls were subjected to 45 minutes of passive upright tilt, with the following variables measured before, during, and after the procedure: cardiac output, heart rate, stroke volume, mean arterial pressure, systemic vascular resistance, and plasma norepinephrine. RESULTS: At rest, heart rate (p < 0.0005) and mean arterial pressure (p = 0.003) were higher, and stroke volume was lower (p < 0.0005), in transplant recipients than they were in controls. With orthostasis, heart rate increased by 30% in controls and by 23% in the late posttransplantation group compared with 13% in the early posttransplantation group (p = 0.028); drop in stroke volume was three times more among controls than among those in either transplantation group (p < 0.001); late transplant recipients had higher norepinephrine increases than did the other two groups (p = 0.012). CONCLUSION: With the exception of heart rate, patterns of hemodynamic response to orthostatic stress after transplantation remain consistent over time and differ from controls. Among transplant recipients, higher mean arterial pressure mitigates the force of gravity and prevents drops in stroke volume. Clinicians may anticipate that transplant recipients will tolerate postural maneuvers well. Later after transplantation, however, orthostatic tolerance is associated with increased norepinephrine release, consistent with enhanced sympathoactivation.

Beyond sociodemographics: factors influencing the decision to seek treatment for symptoms of acute myocardial infarction.
OBJECTIVE: To determine the impact of sociodemographic, clinical, cognitive, emotional, and social factors on patient delay in seeking treatment for symptoms of acute myocardial infarction. DESIGN: Multicenter descriptive survey. SETTING: Forty-three hospitals in North America. SUBJECTS: Two hundred and seventy-seven patients with confirmed acute myocardial infarction enrolled in a thrombolytic clinical trial. OUTCOME MEASURES: Time from symptom onset to arrival at the hospital for treatment. RESULTS: Patients with longer delays were older, had lower incomes, had diabetes, experienced their symptoms at home, did not appraise their symptoms as serious or originating from the heart, had symptoms that were intermittent in nature, waited to see whether symptoms disappeared, worried about troubling others, feared what might happen if they sought treatment, and did not realize the importance of symptoms. CONCLUSION: Patient appraisal of seriousness of symptoms is related to delay, whereas severity, nature, and knowledge of symptoms are not related. Cognitive and emotional responses affect patients' decisions to seek treatment.

Do apnea monitors decrease emotional distress in parents of infants at high risk for cardiopulmonary arrest?
INTRODUCTION: The immediate post-partum period is stressful for most parents. The need to use a home apnea monitor may tax parental coping skills even further. Therefore, we conducted a study to assess the psychosocial consequences of apnea monitoring on parental emotional distress and family functioning. METHOD: We studied 104 parents of infants at high risk for cardiopulmonary arrest. Fifty-two parents had infants who used home apnea monitors, and 52 parents were age-matched and gender-matched control subjects. Data were collected during the infant's hospitalization, and then at 2 weeks, 3 months, and 6 months after discharge. At 1 year, parents were interviewed about their attitudes toward using the apnea monitor. RESULTS: Both groups experienced elevated levels of emotional distress, but the group with infants who used the monitors had significant increases in depression and hostility immediately following discharge from the hospital compared with baseline, whereas the non-monitored group had a significant increase in hostility at 6 months. At 1-year follow-up, the majority of the parents reported that they used the monitor every night, felt more secure in using it, and judged it helpful. DISCUSSION: The immediate period following hospital discharge of infants who need to use a home apnea monitor is characterized by significant emotional distress for the parents, which resolves over time. Anticipatory education and counseling of parents is recommended.

Effect of cardiopulmonary resuscitation training for parents of high-risk neonates on perceived anxiety, control, and burden.
OBJECTIVES STUDY OBJECTIVES: (1) To compare the effects of 3 methods of cardiopulmonary resuscitation (CPR) training for parents of infants at risk for cardiac or respiratory arrest on anxiety, perception of control, and sense of burden; and (2) to identify parents' attitudes about CPR training and willingness to perform CPR if needed. METHODS: A longitudinal, controlled trial was conducted with parents and other caretakers of high-risk infants. Subjects were recruited from 5 level III neonatal intensive care units. We enrolled each of 578 subjects in 1 of 4 groups: (1) CPR-Video; (2) CPR-Didactic; (3) CPR-Social Support; or (4) control (no CPR training). Of these, 335 completed the entire study. Data were collected at baseline, and 2 weeks and 6 months after CPR training. The main outcomes measured were perceived anxiety, control, and burden related to caring for a high-risk infant and attitudes about responding to an emergency. RESULTS: Subjects reported moderately high anxiety, sense of burden, and feelings of loss of control before CPR training. Within groups, subjects in all 3 treatment groups reported improvement in perceptions of anxiety, control, and burden 2 weeks after CPR training, with continued improvement evident 6 months after CPR training (P =.001). In contrast, perceptions were unchanged in the control group. Among groups, at 2 weeks there were significant differences in means between control and CPR-Didactic groups (P =.01), and at 6 months there were significant differences in means between control and CPR-Didactic groups (P =.01) and between control and CPR-Social Support groups (P =.01). CONCLUSION: CPR training is an important intervention for promoting a sense of control and reducing the anxiety and sense of burden experienced by parents of neonates at risk for cardiopulmonary arrest.

Treatment-seeking behavior for acute myocardial infarction symptoms in North America and Australia.
OBJECTIVE: The goal of this study was to compare North American and Australian patients' sociodemographic, clinical, cognitive, emotional, and social factors associated with behavior in seeking treatment for symptoms of acute myocardial infarction. PATIENTS: Subjects included 277 North Americans (mean age, 58 +/- 12 years; 72% men) and 147 Australians (mean age, 62 +/- 13 years; 66% men) with acute myocardial infarction. METHODS: Data were obtained with the Response to Symptoms Questionnaire and from the patients' hospital records. RESULTS: In both groups, patients who delayed longer (P </=.05) had lower incomes, known diabetes mellitus, and symptom onset while at home; in addition, they appraised their symptoms as not serious, waited for symptoms to go away, and worried about troubling others. Additional factors associated with longer delay in North Americans (P </=.05) were older age, intermittent symptoms, and attribution of symptoms to a noncardiac cause; other contributing factors include not recognizing the symptoms as cardiac and fearing the consequences of seeking help. In Australians (P </=. 05), contributing factors were fewer years of education, a history of hypertension, and embarrassment about seeking help. CONCLUSION: Programs to reduce delay in response to acute myocardial infarction symptoms must take account of cognitive and emotional processes and differences in response in the particular cultures of patients.

Self-care and quality of life in patients with advanced heart failure: the effect of a supportive educational intervention.
OBJECTIVE: The goal of this study was to determine the effects of a supportive educational nursing intervention on self-care abilities, self-care behavior, and quality of life of patients with advanced heart failure. DESIGN: The study design was an experimental, random assignment. SETTING: The study was located at the University Hospital in Maastricht, The Netherlands. PATIENTS: The study included 179 patients (mean age 73 years, 58% men, New York Heart Association classification III and IV) admitted to a university hospital with symptoms of heart failure. OUTCOME MEASURES: Outcome measures included self-care abilities (Appraisal of Self-care Agency Scale), self-care behavior (Heart Failure Self-care Behavior Scale), 3 dimensions of quality of life (functional capabilities, symptoms, and psychosocial adjustment to illness), and overall well-being (Cantril's ladder of life). INTERVENTION: The intervention patients received systematic education and support by a nurse in the hospital and at home. Control patients received routine care. RESULTS: Self-care abilities did not change as a result of the intervention, but the self-care behavior in the intervention group was higher than the self-care behavior in the control group during follow-up. The effect of the supportive educational intervention on quality of life was limited. The 3 dimensions of quality of life improved after hospitalization in both groups, with no differences between intervention and control group as measured at each follow-up measurement. However, there was a trend indicating differences between the 2 groups in decrease in symptom frequency and symptom distress during the 9 months of follow-up. CONCLUSION: A supportive educational nursing intervention is effective in improving self-care behavior in patients with advanced (New York Heart Association class III-IV) heart failure; however, a more intensive intervention is needed to show effectiveness in improving quality of life.

Gender differences in health perceptions and meaning in persons living with heart failure.
OBJECTIVE: The goal of this study was to determine whether gender differences exist in health perceptions, psychosocial adjustment to illness, and concerns related to illness in patients with heart failure (HF). DESIGN: Thirty-two patients (50% women) from a single outpatient HF clinic were asked to complete standardized tools to assess health perceptions and psychosocial adjustment to illness. Open-ended questions were used to obtain data on concerns related to HF. RESULTS: The women had higher health perceptions than men did; they also demonstrated better psychosocial adjustment to illness. The qualitative data further suggest that women ascribed more positive meanings to their illness than men did. CONCLUSION: The current study underscored the importance of gender differences in health perceptions related to HF. Patient teaching and counseling can be tailored to address the gender-specific concerns of men and women suffering with this condition to improve patient outcomes.

Relationship between psychosocial variables and compliance in patients with heart failure.
OBJECTIVE: The purpose of this study was to describe the socio-demographic, psychosocial, and social support variables that predict compliance to treatment regimens in HF patients. DESIGN AND SETTING: Semistructured interviews were conducted on 82 patients at an outpatient heart failure clinic to gather data related to compliance behaviors. Five standardized instruments were used to gather data on patients' psychosocial health status and perceived social support. RESULTS: The overall compliance rate was 85.13 (10.01%). Higher levels of compliance (> 90%) were noted for follow-up appointments, medications, smoking, and alcohol cessation. Poor compliance was observed with dietary and exercise recommendations (71% and 53%, respectively). In a multivariate model, higher education, higher mental and physical health status and neuroticism independently contributed to 24% of the variance in overall compliance. CONCLUSION: The study supports that HF patients had poor compliance with dietary and exercise regimens. Since following a dietary and exercise regimen has been demonstrated to reduce morbidity in this population, strategies to increase compliance should be rigorously pursued [corrected].

Decisive situations influencing spouses' support of patients with heart failure: a critical incident technique analysis.
OBJECTIVE: The aim of this study was to describe decisive situations experienced by spouses of patients with heart failure that could potentially affect their ability to provide social support to the patient. METHODS: A qualitative descriptive design with a critical incident technique was used. Twenty-three informants, 15 women and 8 men, who were spouses of patients with severe heart failure were strategically chosen to ensure maximal variation in sociodemographic data and experiences as a spouse. RESULTS: Decisive situations influenced the experience of spouses of patients with heart failure in a manner that was either positive (involvement with others) or negative (feeling like an outsider). When spouses were given attention and treated like persons of value, they experienced involvement with others. In these cases, spouses had someone to turn to and were included in the physical care. In contrast, when spouses were kept at a distance by the patient, were socially isolated, and received insufficient support from children, friends, and health care professionals, they experienced feeling like an outsider. CONCLUSIONS: By identifying spouses' experiences, health care professionals can assess which kind of specific interventions should be used to improve the life situation of the patient with heart failure and his or her spouse.

Effect of positioning on SvO2 in the critically ill patient with a low ejection fraction.
BACKGROUND: Critically ill patients with a low ejection fraction may be vulnerable to decreased mixed venous oxygen saturation (SvO2) resulting from position change. OBJECTIVES: The objectives of this study were to describe the effects of changes in positioning on SvO2 in critically ill patients with a low ejection fraction (< or = 30%) and to describe the contribution of variables of oxygen delivery (DO2) and oxygen consumption (VO2) to the variance in SvO2. METHOD: An experimental two-group repeated-measures design was used to study 42 critically ill patients with an ejection fraction of less than or equal to 30% (M= 19.5%). Patients were assigned randomly to one of two position sequences: supine, right lateral, left lateral; or supine, left lateral, right lateral. Data on SvO2 were collected at baseline, each minute after position change for 5 minutes, and at 15 and 25 minutes. RESULTS: Repeated-measures multivariate analysis of variance showed a difference in SvO2 among the three positions across time (p< .0001), with the greatest differences occurring within the first 4 minutes and in the left lateral position. Stepwise multiple regression showed that VO2 accounted for a greater proportion of the variance in SvO2 with position change than did DO2 (54% [p = .001] vs. 31% [p= .001]). CONCLUSIONS: Changes in SVO2 occur with positioning in critically ill patients with a low ejection fraction. These changes are transient and are the result of changes in VO2 rather than changes in DO2.

Evidence of time-dependent autonomic reinnervation after heart transplantation.
BACKGROUND: Confirming the clinical significance of reinnervation is important in understanding and anticipating how heart rate (HR) responses of transplant recipients to physiologic stress differs early and late after transplant from that of normal individuals. OBJECTIVES: To evaluate the functional significance of cardiac reinnervation early and late after heart transplantation. METHODS: Handgrip and deep breathing tests, passive 80 degrees head-up tilt, and heart rate (HR) responsiveness of 33 transplant recipients (n = 16 at < 5 months and n = 17 at > 1 year after transplant) were compared with those of 16 age- and sex-matched control participants. RESULTS: HR responses to handgrip and passive tilt were absent early after transplant. HR acceleration normalized but was blunted late after transplant. These findings are consistent with late (>1 year) sympathetic reinnervation in transplant recipients. CONCLUSIONS: When caring for transplant recipients, nurses should consider the time elapsed since transplant in evaluating HR responsiveness to common procedures and interventions.

Factors differentiating dropouts from completers in a longitudinal, multicenter clinical trial.
BACKGROUND: Subject dropout from a prospective, longitudinal trial can produce biases in the remaining sample that affect study findings and their interpretation, yet little is known about factors contributing to dropout. OBJECTIVE: To determine characteristics differentiating those who complete from those who drop out of a longitudinal multicenter clinical trial. METHODS: In this study, 578 parents and other caretakers of infants at risk for cardiopulmonary arrest enrolled in a longitudinal trial investigating the psychosocial impact of cardiopulmonary resuscitation training. In this secondary analysis, the baseline sociodemographic, emotional, psychosocial, and infant characteristics of those who dropped from the trial were compared with those who completed the study. RESULTS: The study was completed by 60% (n = 347) of the participants. Those most likely to drop out were fathers or other caretakers (vs. mothers) employed outside the home who spoke English (vs. Spanish); were assigned to an experimental group (vs. a control group); had higher levels of depression, hostility, and overall psychosocial distress; and held negative views about health care. CONCLUSION: Although a few sociodemographic characteristics differentiated dropouts from completers, personal, emotional and psychosocial factors were the predominant predictors of dropouts. Other reputed sources of retention difficulties (e.g., income, education, minority status, lack of social support, or problems with family functioning) did not predict dropout.

Is anxiety early after myocardial infarction associated with subsequent ischemic and arrhythmic events?
OBJECTIVE: Acute myocardial infarction is often accompanied by anxiety, but the effect of this emotion on recovery is unclear. The purpose of this study was to determine the association between patient anxiety early after acute myocardial infarction and the incidence of subsequent in-hospital complications. METHODS: We assessed anxiety level within 48 hours of patient arrival at the hospital in 86 confirmed myocardial infarction patients. Anxiety was measured using the Brief Symptom Inventory. Myocardial infarction complications were defined as reinfarction, new onset ischemia, ventricular fibrillation, sustained ventricular tachycardia, or in-hospital death. RESULTS: More complications were seen in patients with higher versus lower levels of anxiety (19.6% vs 6%; p = .001). Multiple logistic regression was used to control for those clinical and sociodemographic factors that can influence the incidence of complications and demonstrated that higher anxiety level was independently predictive of complications. Patients with higher anxiety levels were 4.9 times (p = .001) more likely to have subsequent complications. CONCLUSIONS: Anxiety early after myocardial infarction onset is associated with increased risk of ischemic and arrhythmic complications. This finding suggests that anxiety should be considered among the conventional risk factors for in-hospital acute myocardial infarction complications.
