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2.

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3.

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4.

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5.

Background
There is limited evidence on the degree of cognitive impairment and its association with physical functional capacity among patients with heart failure (HF) in Korea.Objectives
In this study, we compared cognitive impairment between patients with HF and community-dwelling participants with non-HF medical conditions (medical participants) and its association with physical functional capacity.Methods
We conducted a cross-sectional comparative study and assessed the neuropsychological cognitive status (Seoul Neuropsychological Screening Battery) and physical functional capacity (Duke Activity Status Index) of patients with HF and medical participants using face-to-face interviews.Results
One hundred and eighteen patients with HF (age, 65.45 ± 9.38 years; men, 57.6%; left ventricular ejection fraction, 34.93 ± 8.72%) and 83 medical participants (age, 66.02 ± 8.28 years; men, 47.0%) were included. Using seventh-percentile medical participant Z-scores as cutoffs, memory and executive function were worse in patients with HF than in medical participants: immediate (35.0% vs. 6.0%) and delayed recall memory (34.5% vs. 8.4%), and executive function (28.6% vs. 6.0%). Independent of age, sex, education, comorbidity, and HF status, executive function was a significant predictor of physical functional capacity (b = 1.82, p = .021).Conclusions
More patients with HF had impaired memory and executive function, which were associated with their physical functional capacities. 相似文献6.

Background
Research findings on the value of nurse certification were based on subjective perceptions or biased by correlations of certification status and global clinical factors. In heart failure, the value of certification is unknown.Objectives
Examine the value of certification based nurses' decision-making.Methods
Cross-sectional study of nurses who completed heart failure clinical vignettes that reflected decision-making in clinical heart failure scenarios. Statistical tests included multivariable linear, logistic and proportional odds logistic regression models.Results
Of nurses (N = 605), 29.1% were heart failure certified, 35.0% were certified in another specialty/job role and 35.9% were not certified. In multivariable modeling, nurses certified in heart failure (versus not heart failure certified) had higher clinical vignette scores (p = 0.002), reflecting higher evidence-based decision making; nurses with another specialty/role certification (versus no certification) did not (p = 0.62).Conclusions
Heart failure certification, but not in other specialty/job roles was associated with decisions that reflected delivery of high-quality care. 相似文献7.

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
Exercise confidence predicts exercise adherence in heart failure (HF) patients. The association between simple tests of functional capacity on exercise confidence are not known.Objectives
To evaluate the association between a single 6-min walk test (6MWT) and exercise confidence in HF patients.Methods
Observational study enrolling HF outpatients who completed the Cardiac Depression Scale and an Exercise Confidence Survey at baseline and following the 6MWT. Paired t-test was used to compare repeated-measures data, while Repeated Measures Analysis of Covariance was used for multivariate analysis.Results
106 HF patients were enrolled in the study (males, 82%; mean age, 64 ± 12 years). Baseline Exercise Confidence was inversely associated with age (p < 0.01), NYHA class (p < 0.001), and depression (p < 0.001). The 6MWT was associated with an improvement in Exercise Confidence (F(1,92) = 5.0, p = 0.03) after adjustment for age, gender, HF duration, NYHA class and depression.Conclusions
The 6MWT is associated with improved exercise confidence in HF patients. 相似文献11.

Background
In critically ill patients, clinicians can have difficulty obtaining accurate oximetry measurements.Objective
To compare the accuracy of nasal alar and forehead sensor measurements and incidence of pressure injury.Methods
43 patients had forehead and nasal alar sensors applied. Arterial samples were obtained at 0, 24, and 120 hours. Oxygen saturations measured by co-oximetry were compared to sensor values. Skin was assessed every 8 hours.Results
Oxygen saturations ranged from 69.8%-97.8%, with 18% of measures < 90%. Measurements were within 3% of co-oximetry values for 54% of nasal alar compared to 35% of forehead measurements. Measurement failures occurred in 6% for nasal alar and 22% for forehead. Three patients developed a pressure injury with the nasal alar sensor and 13 patients developed a pressure injury with the forehead sensor (χ2 = 7.68; p = .006).Conclusions
In this group of patients with decreased perfusion, nasal alar sensors provided a potential alternative for continuous monitoring of oxygen saturation. 相似文献12.

Background
Heart failure (HF) self-care is important in reducing clinical events (all-cause mortality, emergency room visits and hospitalizations). HF self-care behaviors are multidimensional and include maintenance (i.e. daily adherence behaviors), management (i.e. symptom response behaviors) and consulting behaviors (i.e. contacting a provider when appropriate). Across these dimensions, patterns of successful patient engagement in self-care have been observed (e.g. successful in one dimension but not in others), but no previous studies have linked patterns of HF self-care to clinical events.Objectives
To identify patterns of self-care behaviors in HF patients and their association with clinical events.Methods
This was a prospective, non-experimental, cohort study. Community-dwelling HF patients (n = 459) were enrolled across Italy, and clinical events were collected one year after enrollment. We measured dimensions of self-care behavior with the Self-Care of HF Index (maintenance, management, and confidence) and the European HF Self-care Behavior Scale (consulting behaviors). We used latent class mixture modeling to identify patterns of HF self-care across dimensions, and Cox proportional hazards modeling to quantify event-free survival over 12 months of follow-up.Results
Patients (mean age 71.8 ± 12.1 years) were mostly males (54.9%). Three patterns of self-care behavior were identified; we labeled each by their most prominent dimensional characteristic: poor symptom response, good symptom response, and maintenance-focused behaviors. Patients with good symptom response behaviors had fewer clinical events compared with those who had poor symptom response behaviors (adjusted hazard ratio = 0.66 [0.46–0.96], p = 0.03). Patients with poor symptom response behaviors had the most frequent clinical events. Patients with poor symptom response and those with maintenance-focused behaviors had a similar frequency of clinical events.Conclusions
Self-care is significantly associated with clinical events. Routine assessment, mitigation of barriers, and interventions targeting self-care are needed to reduce clinical events in HF patients. 相似文献13.

Background
Multidisciplinary disease management programs (MDMP) for patients with heart failure (HF) have been delivered, but evidence of their effectiveness in China is limited.Objective
To determine if a MDMP improves quality of life (QoL), physical performance, depressive symptoms, self-care behaviors and mortality or rehospitalization in patients with HF in China.Methods
This is a randomized controlled single center trial in which patients with HF received either MDMP with discharge education, physical training, follow-up visits and telephone calls for 180 days (n = 31) or standard care (SC, n = 31).Results
Compared with SC, QoL, depressive symptoms, and self-care behaviors were significantly improved by MDMP from baseline to 180 days (37% vs 66%, 20% vs 61%, and 8% vs 33%, respectively, all p < 0.001). There were no differences in physical performance and mortality or rehospitalization during follow-up.Conclusions
A HF MDMP can improve QoL, depressive symptoms and self-care behaviors in China. 相似文献14.

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15.

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16.

Breakthrough candidemia (BTC) on fluconazole was associated with non-susceptible Candida spp. and increased mortality. This nationwide FUNGINOS study analyzed clinical and mycological BTC characteristics.Methods
A 3-year prospective study was conducted in 567 consecutive candidemias. Species identification and antifungal susceptibility testing (CLSI) were performed in the FUNGINOS reference laboratory. Data were analyzed according to STROBE criteria.Results
43/576 (8%) BTC occurred: 37/43 (86%) on fluconazole (28 prophylaxis, median 200 mg/day). 21% BTC vs. 23% non-BTC presented severe sepsis/septic shock. Overall mortality was 34% vs. 32%. BTC was associated with gastrointestinal mucositis (multivariate OR 5.25, 95%CI 2.23–12.40, p < 0.001) and graft-versus-host-disease (6.25, 1.00–38.87, p = 0.05), immunosuppression (2.42, 1.03–5.68, p = 0.043), and parenteral nutrition (2.87, 1.44–5.71, p = 0.003). Non-albicans Candida were isolated in 58% BTC vs. 35% non-BTC (p = 0.005). 63% of 16 BTC occurring after 10-day fluconazole were non-susceptible (Candida glabrata, Candida krusei, Candida norvegensis) vs. 19% of 21 BTC (C. glabrata) following shorter exposure (7.10, 1.60–31.30, p = 0.007). Median fluconazole MIC was 4 mg/l vs. 0.25 mg/l (p < 0.001). Ten-day fluconazole exposure predicted non-susceptible BTC with 73% accuracy.Conclusions
Outcomes of BTC and non-BTC were similar. Fluconazole non-susceptible BTC occurred in three out of four cases after prolonged low-dose prophylaxis. This implies reassessment of prophylaxis duration and rapid de-escalation of empirical therapy in BTC after short fluconazole exposure. 相似文献17.

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18.

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19.

Background
The neutrophil to lymphocyte ratio (NLR), has been proposed as potential indicator of cardiovascular events. Our aim was to determine the relationship between NLR and development of myocardial injury after non-cardiac surgery (MINS).Methods
This observational cohort study included 255 consecutive noncardiac surgery patients aged ≥45 years. Electrocardiography recordings and high sensitivity cardiac troponin T (hscTnT) levels of the patients were obtained for a period of 3 days postoperatively.Results
MINS was detected in 30 (11.8%) patients using the cut-off level of ≥14 ng/L for hscTnT. In the MINS group NLR (3.79 ± 0.7 vs. 2.69 ± 0.6, p < 0.000) values were higher than non-NLR group. The NLR to be independently associated with the development of MINS (OR: 11.690; CI: 4.619–29.585, p < 0.000).Conclusions
NLR seems to be a simple, easy and cheap tool to predict the development of MINS in patient undergoing non-cardiac surgery. 相似文献20.
