Background
African Americans with heart failure (HF) have the highest rates of depression among all ethnicities in the USA.Objectives
To compare the effects by race on depressive symptoms and topics discussed in the first clinic appointment after HF hospitalization.Methods
This study is a secondary analysis of data from a randomized clinical trial testing a patient group discussion of HF self-management with 93 Caucasians and 77 African Americans.Results
Reduction in depressive symptoms was significantly greater among African American patients within the intervention group (F = 3.99, p = .047) than controls. There were significant differences by race in four topics (dietitian referral, appointment date, help preparing discussion questions, and advice on worsening HF symptoms) concerning patient-physician discussions.Conclusion
The intervention showed greater effect in reducing depressive symptoms among African Americans than Caucasians. Preparing patients for discussions at physician appointments on diet, depressive symptoms, and HF symptoms is recommended. 相似文献2.

Background
More evidence is needed about factors that influence self-management behaviors in persons with heart failure.Objective
To test a correlational mediation model of the independent variables of health literacy, patient activation, and heart failure knowledge with heart failure self-management behaviors.Methods
The study used a prospective, cross-sectional, correlational design. Correlation and multiple regression were used to analyze associations among variables. Results: Of 151 participants, 57% were male, and mean age was 68 years. Heart failure self-management behaviors was positively correlated with patient activation level (p = .0008), but not with health literacy or heart failure knowledge.Conclusions
Persons with heart failure may better manage their condition if sufficiently activated, regardless of their level of health literacy or knowledge of heart failure disease and management processes. 相似文献3.

Background
Concerns remain about the burden of nursing care required to implement pulmonary artery pressure monitoring of heart failure patients.Methods
We conducted a retrospective analysis of patients (N = 15) with a PAP sensor at our center. We defined three categories of PAP activity and estimated the nursing time spent on PAP monitoring.Results
During the 6 months after implantation, the median patient contact time was 67 (55–75) minutes/patient/month and the median frequency of patient contact was 5.8 (4.6–6.4) contacts/patient/month. The intensity of nurse-patient contact decreased after the first 3 months (81 [52–102] minutes/patient/month vs. 45 [29–61] minutes/patient/month; P = 0.005).Conclusions
The intensity of nurse-patient contact increased significantly after PAP sensor implantation but declined after the first 3 months with medical stabilization. These data from our center may serve as a benchmark to project the nursing time required to support PAP monitoring in practice. 相似文献5.

Background
The relationship between physical heart failure (HF) symptoms and pathophysiological mechanisms is unclear.Objective
To quantify the relationship between plasma β-adrenergic receptor kinase-1 (βARK1) and physical symptoms among adults with HF.Methods
We performed a secondary analysis of data collected from two studies of adults with HF. Plasma βARK1 was quantified using an enzyme-linked immunosorbent assay. Physical symptoms were measured with the HF Somatic Perception Scale (HFSPS). Generalized linear modeling was used to quantify the relationship between βARK1 and HFSPS scores.Results
The average age (n = 94) was 54.5 ± 13.1 years, 76.6% were male, and a majority (83.0%) had Class III or IV HF. βARK1 was significantly associated with HFSPS scores (β = 0.22 ± 0.10, p = 0.038), adjusting for other predictors of physical symptoms (model R2 = 0.250, F(7, 70) = 3.34, p = 0.004).Conclusions
Higher βARK1 is associated with worse physical HF symptoms, pinpointing a potential pathophysiologic underpinning. 相似文献6.

Background
Symptoms of anxiety, depression, and cognitive impairment are common in heart failure (HF) patients, but there are inconsistencies in the literature regarding their relationship and effects on exercise capacity.Objectives
The aim of this study was to explore the relationships between exercise capacity and anxiety, depression, and cognition in HF patients.Methods
This was a secondary analysis on the baseline data of the Italian subsample (n = 96) of HF patients enrolled in the HF-Wii study. Data was collected with the 6-minute walk test (6MWT), Hospital Anxiety and Depression Scale, and Montreal Cognitive Assessment.Results
The HF patients walked an average of 222 (SD 114) meters on the 6MWT. Patients exhibited clinically elevated anxiety (48%), depression (49%), and severe cognitive impairment (48%). Depression was independently associated with the distance walked on the 6MWT.Conclusions
The results of this study reinforced the role of depression in relation to exercise capacity and call for considering strategies to reduce depressive symptoms to improve outcomes of HF patients. 相似文献7.

Background
Nationally-derived models predicting 30-day readmissions following heart failure (HF) hospitalizations yield insufficient discrimination for institutional use.Objective
Develop a customized readmission risk model from Medicare-employed and institutionally-customized risk factors and compare the performance against national models in a medical center.Methods
Medicare patients age ≥ 65 years hospitalized for HF (n = 1,454) were studied in a derivation cohort and in a separate validation cohort (n = 243). All 30-day hospital readmissions were documented. The primary outcome was risk discrimination (c-statistic) compared to national models.Results
A customized model demonstrated improved discrimination (c-statistic 0.72; 95% CI 0.69 – 0.74) compared to national models (c-statistics of 0.60 and 0.61) with a c-statistic of 0.63 in the validation cohort. Compared to national models, a customized model demonstrated superior readmission risk profiling by distinguishing a high-risk (38.3%) from a low-risk (9.4%) quartile.Conclusions
A customized model improved readmission risk discrimination from HF hospitalizations compared to national models. 相似文献8.

Background
Emergency room utilization and hospital readmission rates are disproportionately high for heart failure patients (HF). Emergency department (ED) utilization is intimately intertwined with hospital readmissions.Objective
Describe the arrival time distribution of HF patients presenting to the ED.Method
The study analyzed heart failure discharge data from the Florida State Emergency Department Database and the Florida State Inpatient Database from the Healthcare Cost and Utilization Project of the Agency for Healthcare Research and Quality. Data were treated as a Poisson process and analyzed using functional data analysis tools.Results
HF arrivals are multi-modal with the largest peak arrival time in the middle of the day as well as a smaller peak in the early morning hours, especially in rural areas.Conclusions
The arrival pattern has minor differences in rural and urban areas. HF clinic appointments should be established in the early morning hours when these patients utilize the ED. 相似文献9.

Background
Heart Failure (HF) is a public health problem globally affecting approximately 6 million in the United States.Objectives
A tailored position statement was developed by the American Association of Heart Failure Nurses (AAHFN) and their Research Consortium to assist researchers, funding institutions and policymakers with improving HF clinical advancements and outcomes.Methods
A comprehensive review was conducted using multiple search terms in various combinations to describe gaps in HF nursing science. Based on gaps described in the literature, the AAHFN made recommendations for future areas of research in HF.Results
Nursing has made positive contributions through disease management interventions, however, quality, rigorous research is needed to improve the lives of patients and families while advancing nursing science.Conclusions
Advancing HF science is critical to managing and improving patient outcomes while promoting the nursing profession. Based on this review, the AAHFN is putting forth a call to action for research designs that promote validity, sustainability, and funding of future nursing research. 相似文献10.

Background
Heart failure education programs are not standardized. The best form of education is unclear. We evaluated whether addition of a novel tablet application to nurse practitioner (NP) education was superior to NP education alone in reducing 30-day readmission after heart failure hospitalization.Methods
From February 2015-March 2016, patients admitted to a quaternary academic center with primary diagnosis of heart failure were randomized to 1) treatment – NP education plus tablet application (interactive conditional logic program that flags patient questions to medical staff), or 2) control – NP education. The primary outcome was reduction in 30-day readmission rate. Secondary outcomes included satisfaction and education assessed via survey.Results
Randomization included 60 patients to treatment and 66 to control. A total of 13 patients withdrew prior to intervention (treatment n = 4, control n = 1) or were lost to follow-up (treatment n = 3, control n = 5). The 30-day readmission rate trended lower for treatment compared with control, but results were not statistically significant (13.2% [7/53], 26.7% [16/60], respectively, P = .08). Similarly, satisfaction trended higher with treatment than control (P = .08). Treatment patients rated explanations from their physicians higher than control (Always: 83.7%, 55.8%, respectively, P = .01).Conclusions
NP education plus tablet use was not associated with significantly lower 30-day readmission rates in comparison with NP alone, but a positive trend was seen. Patient satisfaction trended higher and heart failure explanations were better with NP education plus tablet. A larger study is needed to determine if NP education plus tablet reduces readmission rates following heart failure admission. 相似文献11.

Background
Higher patient-caregiver mutuality is associated with improved patient and caregiver outcomes, but no studies have tested the psychometric characteristics of the mutuality scale (MS) in heart failure (HF) patient and caregiver population.Objectives
To test the validity and reliability of the MS.Methods
A cross-sectional design. The MS validity and reliability were tested with confirmatory factor analysis (CFA) and hypothesis testing, and with Cronbach's alpha and model-based internal consistency index, respectively.Results
CFA supported the validity of the MS in the HF patient and caregiver versions. Hypothesis testing showed significant correlations between both versions of the MS and anxiety, depression, quality of life, and self-care. Also, MS caregiver version scores correlated significantly with caregiver preparedness. Cronbach's alphas and the model-based internal consistency index ranged between 0.72 and 0.94 in both versions.Conclusions
The Mutuality Scale showed supportive validity and reliability for HF patients and caregivers. 相似文献12.

Background
The onset of acute heart failure is known to be associated with increased physical activity and other specific behaviors that can trigger hemodynamic deterioration. This analysis aimed to describe the distribution of triggers in patients hospitalized for acute heart failure, and investigate their effects on in-hospital outcomes.Methods
Consecutive patients hospitalized for acute heart failure between 2010 and 2014 were registered in a multicenter data registration system (72 institutions within Tokyo, Japan). Baseline demographics and in-hospital mortality were extracted from 17,473 patients. Patients with a trigger were grouped based on their triggering event: those with onset during (a) physical activity; (b) sleeping; (c) eating or watching television; (d) bathing or excretion (use of restrooms); and (e) engaging in other activities. These patients were compared with patients without identifiable triggers. Multiple imputation was used for missing data.Results
Patients were predominantly men (57.1%), with a mean age of 76.0 ± 13.0 years; a triggering event was present in 49.1%. No significant difference in baseline characteristics was noted between groups except for younger age, higher blood pressure, and prevalence of signs of congestion in the trigger-positive group. In-hospital mortality rate was 7.9%. Presence of triggers was positively associated with a reduced risk of in-hospital mortality (adjusted odds ratio 0.79; 95% confidence interval, 0.70-0.90; P = .0003). In a delta-adjusted pattern mixture model, the effect of a triggering event on in-hospital mortality remained consistently significant.Conclusion
Triggering events for acute heart failure can provide additional information for risk prediction. Efforts to identify the triggers should be made to classify patients according to risk group. 相似文献13.

Objective
To explore the decision making processes undertaken by community-dwelling individuals with heart failure as they experience symptom changes.Background
Heart failure patients are responsible for daily self-management that includes responding to symptom fluctuations between exacerbations. Despite education, some patients fail to seek timely medical intervention when symptoms change.Methods
Semi-structured interviews were conducted with homecare patients after receiving self-management education. Grounded theory methods and qualitative software were used to collect and analyze the data.Results
Five themes were identified: perceiving symptoms, alleviating actions and control, normalizing symptoms, absence of help seeking behaviors, and decreased functional capacity. Normalizing symptoms included actions taken by participants to mitigate symptom fluctuations. Daily fluctuations were assimilated into normal life resulting in desensitization of symptom recognition and decreased functional capacity.Conclusions
Findings support the need to educate on early symptom recognition, the benefits of safe physical activity, and building a system to support self-management patient-physician collaboration. 相似文献14.

Background
Heart rate variability (HRV), modulated by cardiac autonomic function, is impaired in obstructive sleep apnea (OSA). However, the effect of continuous positive airway pressure (CPAP) on HRV is debated.Objectives
To investigate the associations between CPAP and HRV in OSA.Methods
Based on literature from five databases published through August 2017, we performed a meta-analysis of cohort studies of OSA treated with CPAP. The change of low-frequency band (LF), high-frequency band (HF) and the ratio between LF and HF (LHR) were analyzed.Results
Eleven studies were included. Decreased LF (SMD = ?0.32, 95%CI: ?0.62,?0.01; P = 0.043) and HF (SMD = ?0.51, 95%CI: ?0.95, ?0.08, P = 0.020) were shown while measured on CPAP. When measured off CPAP, HF was increased remarkably (SMD: 0.31, 95%CI: 0.02, 0.60, P = 0.034).Conclusions
CPAP can improve autonomic activity, which might be one mechanism to reduce the risk of cardiovascular diseases in OSA. 相似文献15.

Background
Surgical myectomy reverses heart failure symptoms in the vast majority of obstructive hypertrophic cardiomyopathy patients. However, a small subgroup fails to experience sustained postoperative improvement despite relief of obstruction. Clinical profile of such patients has not been well defined.Methods
Consecutive obstructive hypertrophic cardiomyopathy patients undergoing myectomy at Tufts Medical Center for drug-refractory New York Heart Association III/IV heart failure symptoms, 2004 to 2017, were followed postoperatively for 2.5 ± 2.8 years and assessed for outcome.Results
Of the 503 patients, there were 4 postoperative deaths (0.8%); 480 patients (96%) had sustained improvement to New York Heart Association classes I or II (responders), but 19 (3.8%) developed advanced symptoms (classes III or IV) in the absence of obstruction (nonresponders). Compared with responders, nonresponders were younger (40 ± 13 vs 53 ± 14 years; P < .001) and had greater septal thickness (25 ± 9 vs 20 ± 4 mm; P < .001). Massive hypertrophy (≥30 mm) was 5-fold more common in nonresponders (P < .01). Seven nonresponders developed systolic dysfunction (ejection fraction 20%-47%), 2 days to 6.1 years postoperatively. Four nonresponders underwent heart transplant 3.4 to 9.2 years after myectomy, and 2 others have been listed.Conclusions
Surgical myectomy is highly effective at reversing heart failure symptoms in the vast majority of patients with obstructive hypertrophic cardiomyopathy. However, a small minority experience persistent functional limitation despite surgical relief of outflow obstruction. Predictors of adverse postoperative course were substantial/massive septal thickness and youthful age. Patients who failed to respond symptomatically to myectomy were considered for advanced heart failure treatment, including heart transplantation. 相似文献16.

Background
Congestive heart failure is the leading cause of hospital readmissions. We aimed to assess adherence to and effectiveness of a telehealth protocol designed to prevent hospital admissions for congestive heart failure.Methods
We recruited a random sample of 50 patients with congestive heart failure (mean age 61 years) from a managed care organization. We developed a telehealth platform allowing for daily, real-time reporting of health status and video conferencing. We defined adherence as the percentage of days on which the patient completed the daily check-in protocol. To assess efficacy, we compared admission and readmission rates between the 6-month intervention period and the prior 6 months. Primary outcomes were admissions and readmissions due to congestive heart failure, and secondary outcomes were admissions and readmissions due to any cause.Results
Forty-eight patients (96%) completed the protocol. Approximately half (46%) were at high risk for readmission according to standardized measures. Median 120-day adherence was 96% (interquartile range, 92%-98%), and adherence did not significantly differ across sex, race, age, living situation, depression, cognitive ability, or risk for readmission. Approximately equal proportions of patients were admitted for all causes during the 6-month intervention period versus the comparison period (37% vs 43%; P = .32). Half as many patients were admitted for congestive heart failure during the 6-month intervention period compared with the comparison period (12% vs 25%; P = .11).Conclusion
Adherence to this telehealth protocol was excellent and consistent, even among high-risk patients. Future research should test the protocol using a more rigorous randomized design. 相似文献17.

Background
Myocardial fibrosis has proved to be an important marker and determinant in the pathogenesis of hypertrophic cardiomyopathy. In particular, scar formation, if substantial, can promote ventricular tachyarrhythmias or progressive heart failure in the absence of left ventricular outflow obstruction. Therefore, an intervention to mitigate myocardial fibrosis would be potentially advantageous to hypertrophic cardiomyopathy patients.Methods
Eligible hypertrophic cardiomyopathy patients were randomized 1:1 in a prospective double-blind fashion to spironolactone 50 mg or placebo to be taken over a 12-month period. The primary endpoint was the effect of mineralocorticoid receptor blockade on serum markers of collagen synthesis and degradation. A number of other functional and morphologic variables and biomarkers comprised secondary exploratory measures.Results
Fifty-three hypertrophic cardiomyopathypatients (41 ± 13 years old; 72% men) were randomized; demographic and clinical variable were well matched at baseline. Absolute change between baseline and 12 months did not differ between hypertrophic cardiomyopathy patients treated with spironolactone and those receiving placebo with respect to serum markers of collagen synthesis or degradation, fibrosis by late gadolinium enhancement on cardiac magnetic resonance imaging, or other clinical variables, including objective measure of functional capacity (peak VO2), New York Heart Association functional class, left ventricular wall thickness, mass and volume, and left atrial size, as well as assessment of diastolic function (P = .4-1.0).Conclusions
These findings do not support the use of spironolactone in hypertrophic cardiomyopathy to improve left ventricular remodeling by mitigating myocardial fibrosis or altering clinical course. 相似文献18.

Background
Early heart failure (HF) symptoms are frequently unrecognized for reasons that are unclear. We explored symptom perception in patients with chronic HF.Methods
We enrolled 36 HF out-patients into a longitudinal sequential explanatory mixed methods study. We used objectively measured thoracic fluid accumulation and daily reports of signs and symptoms to evaluate accuracy of detected changes in fluid retention. Patterns of symptom interpretation and response were explored in telephone interviews conducted every 2 weeks for 3-months.Results
In this sample, 44% had a mismatch between objective and subjective fluid retention; younger persons were more likely to have mismatch. In interviews, two patterns were identified: those able to interpret and respond appropriately to symptoms were higher in decision-making skill and the quality of social support received.Conclusion
Many HF patients were poor at interpreting and managing their symptoms. These results suggest a subgroup of patients to target for intervention. 相似文献19.

Background
Clinical and ethical issues persist in determining candidacy for advanced heart failure (HF) therapies in elderly patients. Selection takes many factors into account, including “activation” (engagement and ability to self-manage).Objective
To investigate effects of age, activation, and depression/anxiety on selection and 6-month survival of participants considered for therapy.Methods
Consecutive people referred for advanced HF therapy completed the Patient Activation Measure and Hospital Anxiety and Depression Scale. We analyzed data from participants by age (≥65 vs. <65 years), stratified by approval for therapy.Results
Among 168 referred, 109 were approved, with no difference in activation between age groups (88% highly activated). Similarly, activation was not associated with age among those not approved. Activation was related to anxiety in older, approved participants, but not to depression.Conclusions
Concerns regarding reduced self-management in the elderly may not be valid. Age alone should not disqualify a candidate for advanced HF therapy. 相似文献20.
