Heart failure: An update for nurses.

ABSTRACT: Heart failure (HF) is a chronic syndrome that requires patients to manage signs and symptoms and adhere to a complex medication regimen. This article discusses updates in HF care related to a universal definition and new therapies, focusing on the four pillars of therapy for HF with reduced ejection fraction.

Decision Delay Is a Significant Contributor to Prehospital Delay for Stroke Symptoms.

Prehospital delay after stroke symptom onset is a primary barrier to eligibility for reperfusion therapies. Decision delay is an understudied contributor to prehospital delay. We aimed to explore decision delay as a component of prehospital delay. For this correlational study, 170 Thai acute stroke patients were interviewed to explore their treatment-seeking decision factors: prior stroke knowledge, onset context, and cognitive, emotional, and behavioral factors. Participants' mean age was 61.2 years, and 46% were women. Median decision delay and prehospital delay times were 120 and 372 minutes. Decision delay represented 49% of prehospital delays. Factors shortening decision delay were atrial fibrillation, prior stroke knowledge, perceived cause of symptoms as stroke, perceived severity of symptoms, and advice from bystanders to seek treatment. In contrast, seeking support from others and self-treatment affected prolonged decision delay. Shortening decision delay, often under the patient or bystander control, can reduce overall prehospital delay.

Nurses' personal perceptions of clinical work adaptation during COVID-19.

BACKGROUND: The clinical work of nurses across the United States was profoundly impacted by the Coronavirus (COVID-19) pandemic. Nurses in both hospital and outpatient settings had to adapt quickly to the continuously changing healthcare environment. OBJECTIVE: To describe nurses' responses to open-ended questions of their clinical work adaption during the COVID-19 pandemic. METHODS: A descriptive, cross-sectional survey with four open-ended questions was completed by practicing HF nurses. Content analysis was used to analyze the written data. RESULTS: The 127 nurses who provided one to four narrative responses, 55.1% were clinical registered nurses and 44.9% were advance practice nurses. Four categories emerged: changing paths exemplifies work challenges, developing technical skills and resources, asking better questions while listening, and showing resilience through new paths to optimize work. CONCLUSION: Understanding perceptions of nurses' adaptions to clinical work made during the pandemic provides insight into the challenges and opportunities for development in the future.

Multimorbidity phenotypes in patients presenting to the emergency department with possible acute coronary syndrome.

BACKGROUND: Multimorbidity (> 2 conditions) increases the risk of adverse outcomes and challenges health care systems for patients with acute coronary syndrome (ACS). These complications may be partially attributed to ACS clinical care which is driven by single-disease-based practice guidelines; current guidelines do not consider multimorbidity. OBJECTIVES: To identify multimorbidity phenotypes (combinations of conditions) with suspected ACS. We hypothesized that: 1) subgroups of patients with similar multimorbidity phenotypes could be identified, 2) classes would differ according to diagnosis, and 3) class membership would differ by sex, age, functional status, family history, and discharge diagnosis. METHODS: This was a secondary analysis of data from a large multi-site clinical study of patients with suspected ACS. Conditions were determined by items on the Charlson Comorbidity Index and the ACS Patient Information Questionnaire. Latent class analysis was used to identify phenotypes. RESULTS: The sample (n = 935) was predominantly male (68%) and middle-aged (mean= 59 years). Four multimorbidity phenotypes were identified: 1) high multimorbidity (Class 1) included hyperlipidemia, hypertension (HTN), obesity, diabetes, and respiratory disorders (COPD or asthma); 2) low multimorbidity (Class 2) included only obesity; 3) cardiovascular multimorbidity (Class 3) included HTN, hyperlipidemia, and coronary heart disease; and 4) cardio-oncology multimorbidity (Class 4) included HTN, hyperlipidemia, and cancer. Patients ruled-in for ACS primarily clustered in Classes 3 and 4 (OR 2.82, 95% CI 1.95-4.05, p = 0.001 and OR 1.76, 95% CI 1.13-2.74, p = 0.01). CONCLUSION: Identifying and understanding multimorbidity phenotypes may assist with risk-stratification and better triage of high-risk patients in the emergency department.

Standardized Patient Education for Decompensated Cirrhotic Patients and Impact on Clinician Satisfaction.

The development of ascites in patients with cirrhosis can cause numerous complications including abdominal discomfort, pain, respiratory distress, decreased mobility, diminished quality of life, and contributes to an increased mortality. Symptom self-monitoring that incorporates evidence-based treatments has been effective when used by patients with noncirrhotic chronic diseases. Guided by the theory of Self-Care of Chronic Illness, a self-monitoring guide was adapted from an existing validated tool. In the context of a pilot quality initiative, staff nurses educated patients with ascites and their caregivers, with the adapted symptom self-monitoring guide using a standardized process. Clinicians were surveyed regarding their satisfaction with the patient education pre- and post-implementation. Results indicated improved clinician satisfaction with the education provided to patients and their caregivers during the clinic visit. Implementation of self-monitoring may improve clinician and patient satisfaction and clinic workflows. Additional evaluation of the self-monitoring guide and its effect on patient satisfaction, impact on hospital admissions, and outpatient paracentesis is warranted.

Integrating Palliative Care Into Heart Failure Management.

BACKGROUND: The World Health Organization defines palliative care as an approach that improves the quality of life of patients and their families through the prevention and relief of suffering by assessment and treatment of physical, psychosocial, and spiritual problems. Any patient with chronic debilitating disease, including heart failure, is a candidate for interdisciplinary palliative care to manage their complex physical and psychosocial needs. CLINICAL RELEVANCE: The philosophy of palliative care has evolved to include a vision of holistic care extended to all individuals with serious illness and their families or caregivers that should be integrated throughout the continuum of care, including the acute phase. The critical care nurse will likely encounter patients with heart failure who are receiving or are eligible to receive palliative care at various time points during their illness. Critical care nurses therefore play a pivotal role in symptom palliation affecting the heart failure patient's quality of life. PURPOSE: To review the models of palliative care and the role that the critical care nurse plays in symptom palliation and preparation of the patient and their family for transition to other levels and settings of care. CONTENT COVERED: This review addresses the principles and models of palliative care along with how to integrate these principles into all phases of the heart failure disease continuum. Also included are recommendations for palliation of symptoms specific to heart failure patients as well as a discussion of the role of the critical care nurse and the importance of shared decision-making.

mHealth Technology and CVD Risk Reduction.

PURPOSE OF REVIEW: To review existing mHealth-based interventions and examine their efficacy in reducing cardiovascular disease (CVD) risk factors. RECENT FINDINGS: A total of 50 articles are included in this review. The majority of the mHealth interventions targeted a specific CVD risk factor, while 4 addressed 2 or more CVD risk factors. Of the 9 mHealth-supported weight loss intervention trials, 4 resulted in significant weight loss. Four out of 7 RCTs targeting improvement in physical activity reported significant improvement, while 4 of the 8 mHealth-supported smoking cessation intervention trials resulted in smoking abstinence. Of the 10 mHealth-based diabetes intervention trials, 5 reported significant reductions in HbA1c; however, only 3 out of the 9 antihypertension interventions resulted in significant reductions in blood pressure. There is a growing body of literature focused on mHealth interventions that address CVD risk factors. Despite the immense potential of mHealth interventions, evidence of their efficacy in mitigating cardiovascular risk is heterogeneous.

Sex Differences in Prehospital Delay in Patients With Acute Stroke: A Systematic Review.

BACKGROUND: In 2009, the window from symptom onset to administration of tissue plasminogen activator for acute ischemic stroke was extended from 3 to 4.5 hours. Yet no systematic review has addressed prehospital delay by sex for stroke symptoms since this change. PURPOSE: We aimed to (1) compare prehospital delay times-the time from symptom onset to hospital arrival-between women and men with acute stroke or transient ischemic attack and (2) summarize factors influencing prehospital delay by sex. METHODS: The CINAHL, MEDLINE, PubMed, Scopus, and PsycINFO databases were searched using PRISMA guidelines. Inclusion criteria were as follows: (1) quantitative research articles published between May 2008 and April 2019, (2) investigation of prehospital delay among women and men 15 years or older who were given a diagnosis of acute stroke or transient ischemic attack, and (3) English-language publications. The Crowe Critical Appraisal Tool was used to evaluate the quality of studies. RESULTS: Fifteen publications (n = 162 856) met inclusion criteria. Most studies (n = 11) showed no sex differences in prehospital delay. Four studies from Asian-Pacific countries and the United States showed that women had significantly longer prehospital delay compared with men. Older age, minority race/ethnicity (black and Mexican American), and underuse of emergency medical services were associated with prolonged prehospital delay in women. CONCLUSIONS: Most study authors found no differences in prehospital delay between women and men; however, women delayed longer in some Asian-Pacific and American studies. Findings of sex differences were inconclusive.

Navigating Symptom Management in Heart Failure: The Crucial Role of the Critical Care Nurse.

High-acuity, progressive care, and critical care nurses often provide care for patients with heart failure during an exacerbation of acute disease or at the end of life. Identifying and managing heart failure symptoms is complex and requires early recognition and early intervention. Because symptoms of heart failure are not disease specific, patients may not respond to them appropriately, resulting in treatment delays. This article reviews the complexities and issues surrounding the patient's ability to recognize heart failure symptoms and the critical care nurse's role in facilitating early intervention. It outlines the many barriers to symptom recognition and response, including multimorbidities, age, symptom intensity, symptom escalation, and health literacy. The influence of self-care on heart failure management is also described. The critical care nurse plays a crucial role in teaching heart failure patients to identify and respond appropriately to their symptoms, thus promoting early intervention.

The Three Rs for Preventing Heart Failure Readmission: Review, Reassess, and Reeducate.

Despite improvements in heart failure therapies, hospitalization readmission rates remain high. Nationally, increasing attention has been directed toward reducing readmission rates and thus identifying patients with the highest risk for readmission. This article summarizes the evidence related to decreasing readmission for patients with heart failure within 30 days after discharge, focusing on the acute setting. Each patient requires an individualized plan for successful transition from hospital to home and preventing readmission. Nurses must review the patient's current plan of care and adherence to it and look for clues to failure of the plan that could lead to readmission to the hospital. In addition, nurses must reassess the current plan with the patient and family to ensure that the plan continues to meet the patient's needs. Finally, nurses must continually reeducate patients about their plan of care, their plan for self-management, and strategies to prevent hospital readmission for heart failure.

Acute Coronary Syndrome Symptom Clusters: Illustration of Results Using Multiple Statistical Methods.

Researchers have employed various methods to identify symptom clusters in cardiovascular conditions, without identifying rationale. Here, we test clustering techniques and outcomes using a data set from patients with acute coronary syndrome. A total of 474 patients who presented to emergency departments in five United States regions were enrolled. Symptoms were assessed within 15 min of presentation using the validated 13-item ACS Symptom Checklist. Three variable-centered approaches resulted in four-factor solutions. Two of three person-centered approaches resulted in three-cluster solutions. K-means cluster analysis revealed a six-cluster solution but was reduced to three clusters following cluster plot analysis. The number of symptoms and patient characteristics varied within clusters. Based on our findings, we recommend using (a) a variable-centered approach if the research is exploratory, (b) a confirmatory factor analysis if there is a hypothesis about symptom clusters, and (c) a person-centered approach if the aim is to cluster symptoms by individual groups.

Estimated Glomerular Filtration Rate and 6-Minute Walk Distance in African Americans with Mild to Moderate Heart Failure.

BACKGROUND/AIMS: The 6-minute walk test is a measure of functional capacity in patients with heart failure (HF) or chronic kidney disease (CKD). The association between estimated glomerular filtration rate (eGFR) and 6-minute walk distance (6MWD) has not been investigated in African-Americans (AA), despite them having a higher incidence of CKD and chronic HF. Thus, our aim was to determine if eGFR was an independent predictor of 6MWD in AA >50 years of age with HF. METHODS: In this cross-sectional study, we examined the relationship between eGFR and 6MWD in 45 AA patients with HF from an urban outpatient HF clinic, using logistic regression with bootstrapping. RESULTS: The sample consisted of 53% females; mean age = 64.8 ± 9 years, mean eGFR = 61.6 ± 20 mL/min/1.73 m2, and mean 6MWD = 222 ± 78 m. A decrease in eGFR by 10 mL/min/1.73 m2 was associated with 46% higher odds (p = 0.02) of a 6MWD ≤200 m in an unadjusted model and 39-41% higher odds (p = 0.03) of a 6MWD ≤200 m in adjusted models. CONCLUSION: A decrease in eGFR significantly predicted a shorter 6MWD in AA patients with HF. Therefore, a reduction in eGFR may be used as an early marker to identify and manage declining functional capacity in these patients.

Impact of comorbidities by age on symptom presentation for suspected acute coronary syndromes in the emergency department.

BACKGROUND: It is estimated half of acute coronary syndrome (ACS) patients have one or more associated comorbid conditions. AIMS: Aims were to: 1) examine the prevalence of comorbid conditions in patients presenting to the emergency department with symptoms suggestive of ACS; 2) determine if comorbid conditions influence ACS symptoms; and 3) determine if comorbid conditions predict the likelihood of receiving an ACS diagnosis. METHODS: A total of 1064 patients admitted to five emergency departments were enrolled in this prospective study. Symptoms were measured on presentation to the emergency department. The Charlson Comorbidity Index (CCI) was used to evaluate group differences in comorbidity burden across demographic traits, risk factors, clinical presentation, and diagnosis. RESULTS: The most prominent comorbid conditions were prior myocardial infarction, diabetes without target organ damage, and chronic lung disease. In younger ACS patients, higher CCI predicted less chest pain, chest discomfort, unusual fatigue and a lower number of symptoms. In older ACS patients, higher CCI predicted more chest discomfort, upper back pain, abrupt symptom onset, and greater symptom distress. For younger non-ACS patients, higher CCI predicted less chest pain and symptom distress. Higher CCI was associated with a greater likelihood of receiving an ACS diagnosis for younger but not older patients with suspected ACS. CONCLUSIONS: Younger patients with ACS and higher number of comorbidities report less chest pain, putting them at higher risk for delayed diagnosis and treatment since chest pain is a hallmark symptom for ACS.

Symptoms Suggestive of Acute Coronary Syndrome: When Is Sex Important?

BACKGROUND: Studies have identified sex differences in symptoms of acute coronary syndrome (ACS); however, retrospective designs, abstraction of symptoms from medical records, and variations in assessment forms make it difficult to determine the clinical significance of sex differences. OBJECTIVE: The aim of this study is to determine the influence of sex on the occurrence and distress of 13 symptoms for patients presenting to the emergency department for symptoms suggestive of ACS. METHODS: A total of 1064 patients admitted to 5 emergency departments with symptoms triggering a cardiac evaluation were enrolled. Demographic and clinical variables, symptoms, comorbid conditions, and functional status were measured. RESULTS: The sample was predominantly male (n = 664, 62.4%), white (n = 739, 69.5%), and married (n = 497, 46.9%). Women were significantly older than men (61.3 ± 14.6 vs 59.5 ± 13.6 years). Most patients were discharged with a non-ACS diagnosis (n = 590, 55.5%). Women with ACS were less likely to report chest pain as their chief complaint and to report more nausea (odds ratio [OR], 1.56; confidence interval [CI], 1.00-2.42), shoulder pain (OR, 1.76; CI, 1.13-2.73), and upper back pain (OR, 2.92; CI, 1.81-4.70). Women with ACS experienced more symptoms (6.1 vs 5.5; P = .026) compared with men. Men without ACS had less symptom distress compared with women. CONCLUSIONS: Women and men evaluated for ACS reported similar rates of chest pain but differed on other classic symptoms. These findings suggest that women and men should be counseled that ACS is not always accompanied by chest pain and multiple symptoms may occur simultaneously.

A Review of the Literature on Cardiac Symptoms in Older and Younger Women.

OBJECTIVE: To describe acute and prodromal cardiac symptoms in older and younger women. DATA SOURCES: PubMed, CINAHL, MEDLINE, and Web of Science databases were searched for articles published between January 2000 and January 2015. STUDY SELECTION: A combination of the MESH terms acute coronary syndrome, myocardial infarction, symptoms, prodromal symptoms, sex, gender, and age was used. The search was limited to studies on humans published in English and original articles related to symptoms of acute coronary syndrome (ACS) in women with symptoms stratified by age or analyses adjusted for age and/or sex. DATA EXTRACTION: A total of 432 articles were identified, and 20 met the inclusion criteria. DATA SYNTHESIS: Key findings for differences in acute ACS symptoms for women based on age included the following: (a) typical chest pain and pain of any kind were less likely in older women (≥65 years); (b) women were more likely to have nonpain symptoms of nausea, dyspnea, and fatigue after adjustment for age; (c) most researchers did not adjust for menopausal status or hormone replacement therapy; and (d) findings were consistent across international cohorts. The most common prodromal symptoms in women after adjustment for age included unusual fatigue, discomfort in arms, sleep disturbance, anxiety, general chest discomfort, discomfort in jaws/teeth, and shortness of breath. Although chest symptoms were reported by some women, they were not reported by most women. CONCLUSION: Women older than 65 years with ACS experienced fewer symptoms, more ambiguous symptoms, less chest pain, and more dyspnea. Women older than 50 years were more likely to report prodromal symptoms that include sleep disturbance. Many symptom differences that were statistically significant by age, such as chest pain and shortness of breath, may not be clinically relevant.

Measurement of Dyspnea in Ambulatory African Americans With Heart Failure and a Preserved or Reduced Ejection Fraction.

BACKGROUND: Dyspnea is a burdensome and disabling heart failure (HF) symptom. Few studies examining dyspnea in HF have included African Americans (AAs), despite their developing HF at a younger age and having the highest mortality rates. OBJECTIVE: The purpose of this cross-sectional study was to examine dyspnea in AA patients with HF and a preserved ejection fraction (HFpEF) compared with those with a reduced ejection fraction (HFrEF), before and after the 6-minute walk test (6MWT). METHODS: A convenience sample of ambulatory AA patients (HFrEF, n = 26; HFpEF, n = 19) 50 years or older was recruited from an urban HF clinic. The Borg Scale and a visual analog scale (VAS) were used to measure dyspnea intensity before and after the 6MWT. Activity limitations related to dyspnea were described using the modified Medical Research Council Dyspnea Scale. Group comparisons were analyzed using repeated-measures analysis of variance and χ 2tests. Convergent validity was determined between the Borg and VAS using Bland-Altman plots. RESULTS: No significant differences were found in age, gender, and comorbidities between HF groups. Most HFpEF patients reported dyspnea at baseline (Borg, 63%; VAS, 73%) and after the 6MWT (Borg, 78%; VAS, 79%). In the HFrEF group, the prevalence of baseline dyspnea was greater when measured with the VAS (Borg, 34%; VAS, 80%) but was similar between instruments after the 6MWT (Borg, 64%; VAS, 77%). Both groups reported a similar change in dyspnea intensity during and after the 6MWT. The Bland-Altman plots indicated moderate agreement at each time point. Most patients described walking hurriedly or uphill as dyspnea-provoking on the Modified Respiratory Council Dyspnea Scale. CONCLUSIONS: The prevalence of dyspnea at baseline and after the 6MWT was high for both groups, but intensity varied with the dyspnea instrument used.

Effects of exercise interventions on peripheral vascular endothelial vasoreactivity in patients with heart failure with reduced ejection fraction.

Changes in vascular function, such as endothelial dysfunction are linked to the progression of heart failure (HF) and poorer outcomes, such as increased hospitalisations. Exercise training may positively influence endothelial function in HF patients with reduced ejection fraction. The aim of this manuscript is to summarise HF studies evaluating the influence of exercise training on endothelial function as measured by flow mediated vasodilation as a primary outcome and to provide recommendations for future research studies designed to improve peripheral vascular function in HF. Databases were searched for studies published between 1995 and December 2011. Two reviewers determined eligibility and extracted information on study characteristics and quality, exercise interventions, and endothelial function. Eleven articles (N=318 HF participants with an ejection fraction <40%) were eligible for full review. Aerobic, resistance, or combined exercise training improved endothelium-dependent vasodilation as measured by ultrasound or plethysmography. There is less evidence supporting improvement in endothelium-independent function with exercise training. Sample sizes were small and predominantly male. Future research is needed to address the best mode and optimal dose of exercise for all patients with HF including women and subgroups with specific co-morbidities.
