AbstractAcute decompensated heart failure is the leading admitting diagnosis in patients 65 and older with more than 1 million hospitalizations per year in the US alone. Traditional tools to evaluate for and monitor volume status in patients with heart failure, including symptoms and physical exam findings, are known to have limited accuracy. In contrast, point of care lung ultrasound is a practical and evidenced-based tool for monitoring of volume status in patients with heart failure. However, few inpatient clinicians currently use this tool to monitor diuresis. We performed semi-structured interviews of 23 hospitalists practicing in 5 geographically diverse academic institutions in the US to better understand how hospitalists currently assess and monitor volume status in patients hospitalized with heart failure. We also explored their perceptions and attitudes toward adoption of lung ultrasound. Hospitalist participants reported poor reliability and confidence in the accuracy of traditional tools to monitor diuresis and expressed interest in learning or were already using lung ultrasound for this purpose. The time required for training and access to equipment that does not impede workflow were considered important barriers to its adoption by interviewees.

Introduction: Dyspnea is a common presenting problem in the emergency department (ED) that frequently creates a diagnostic challenge for physicians. Acute decompensated heart failure (ADHF) represents a common cause that requires prompt diagnosis and management. Recent studies on dyspneic patients have suggested a potential role for point-of-care ultrasound (PoCUS). The objective of this systematic review was to assess the sensitivity and specificity of early bedside lung ultrasound in patients presenting to the ED with dyspnea. Methods: A search of the literature was conducted using PubMed, EMBASE, the Cochrane Library, bibliographies of previous systematic reviews, and abstracts from major emergency medicine conferences. We included prospective studies that assessed the diagnostic accuracy of B-lines from bedside lung ultrasound in the ED patients compared to a clinical diagnosis of ADHF at hospital discharge. The final diagnosis included at least one of CXR, computed tomography, or BNP. Two reviewers independently screened all titles and abstracts for possible inclusions. Two separate content experts full text-reviewed selected studies and performed quality analysis using a modified Critical Appraisal Skills Program (CASP) questionnaire. Extracted data was assessed with summary receiver operator characteristics curve (SROC) analysis with pooled sensitivity and specificity. Heterogenity was tested. Results: The electronic search yielded 3674 articles of which six met the inclusion criteria and fulfilled CASP requirements for methodological quality. The total number of patients in these studies was 1911. Heterogeneity was noted; due to poorer performance by novice users. Meta-analysis of the data showed that in detecting ADHF, bedside lung ultrasound had a pooled sensitivity of 89.6% (95% CI 69.5 to 97.0%) and a pooled specificity of 88.4% (95% CI 75.0 to 95.1%). The positive likelihood ratio was 6.01 (95% CI 2.93 to 12.32) and negative likelihood ratio was 0.13 (95% CI 0.06 to 0.30). Conclusion: This study suggests that in patients presenting to the ED with undifferentiated dyspnea, early point of care lung ultrasound may be used to confirm the diagnosis of ADHF, which may facilitate earlier appropriate management. Test performance may vary according to experience.

Heart failure (HF) is a leading cause of hospitalisation and healthcare costs worldwide. Acute decompensated heart failure accounts for more than 1 million hospitalisations in the US. Despite advances in the quality of acute and chronic HF disease management, gaps in knowledge about effective interventions to support the transition of care for patients with HF remain. Despite multiple trials of promising therapies, standard care consists of decongestion with IV diuretics and haemodynamic support with vasodilators and inotropes and this has remained largely unchanged during the past 45 years. Newer advances in medical innovations and structural heart disease interventions have now given promise to improved survival, outcomes and quality of life for patients with advanced HF of multiple aetiologies. In this article, we focus on structural interventions in the treatment of patients with HF.

Background: Thiazide diuretics are often utilized to overcome loop diuretic resistance when treating acute decompensated heart failure (ADHF). In addition to a large cost advantage, several pharmacokinetic advantages exist when administering oral metolazone (MTZ) compared with intravenous (IV) chlorothiazide (CTZ), yet many providers are reluctant to utilize an oral formulation to treat ADHF. The purpose of this study was to compare the increase in 24-hour total urine output (UOP) after adding MTZ or CTZ to IV loop diuretics (LD) in patients with heart failure with reduced ejection fraction (HFrEF). Methods and Results: From September 2013 to August 2016, 1002 patients admitted for ADHF received either MTZ or CTZ in addition to LD. Patients were excluded for heart failure with preserved ejection fraction (HFpEF) (n = 469), <24-hour LD or UOP data prior to drug initiation (n = 129), or low dose MTZ/CTZ (n = 91). A total of 168 patients were included with 64% receiving CTZ. No significant difference was observed between the increase in 24-hour total UOP after MTZ or CTZ initiation (1458 [514, 2401] mL vs 1820 [890, 2750] mL, P = .251). Conclusions: Both MTZ and CTZ similarly increased UOP when utilized as an adjunct to IV LD. These results suggest that while thiazide agents can substantially increase UOP in ADHF patients with HFrEF, MTZ and CTZ have comparable effects.

Iodine 123

Background: A four-parameter risk model including cardiac iodine-123 metaiodobenzylguanidine (MIBG) imaging and readily available clinical parameters has been recently developed for the prediction of 2-year cardiac mortality risk in patients with chronic heart failure (CHF) using a Japanese CHF database consisting of 1322 patients. However, there is no information available on the usefulness of 2-year MIBG-based cardiac mortality risk score for the prediction of post-discharge prognosis in patients with heart failure with preserved LVEF (HFpEF) who are admitted with acute decompensated heart failure (ADHF). Methods and Results: Patients' data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT-HFpEF) study, which is a prospective multicenter observational registry for ADHF patients with LVEF ≥50% in Osaka. We studied 239 patients who survived to discharge. Cardiac MIBG imaging was performed just before discharge. The 2-year cardiac mortality risk score was calculated using four parameters, including age, LVEF, NYHA functional class, and the cardiac MIBG heart-to-mediastinum ratio on delayed image. The patients were stratified into three groups based on the 2-year cardiac mortality risk score: low- (<4%), intermediate- (4-12%), and high-risk (>12%) groups. The endpoint was all-cause death. During a follow-up period of 1.6±0.8 years, 33 patients had all-cause death. Multivariate Cox analysis showed that 2-year MIBG-based cardiac mortality risk score was an independent predictor of all-cause death (p=0.0009). There was significant difference in the rate of all-cause death among the three groups stratified by 2-year cardiac mortality risk score (Figure). Conclusions: In this multicenter study, the 2-year MIBG-based cardiac mortality risk score was shown to be useful for the prediction of post-discharge clinical outcome in HFpEF patients admitted for ADHF.

AbstractObjectivesDyspnea is a common presenting problem that creates a diagnostic challenge for physicians in the emergency department (ED). While the differential diagnosis is broad, acute decompensated heart failure (ADHF) is a frequent cause that can be challenging to differentiate from other etiologies. Recent studies have suggested a potential diagnostic role for emergency lung ultrasound (US). The objective of this systematic review was to assess the accuracy of early bedside lung US in patients presenting to the ED with dyspnea.MethodsA systematic search of EMBASE, PubMed, and the Cochrane Library was performed in addition to a grey literature search. We selected prospective studies that reported on the sensitivity and specificity of B-lines from early lung ultrasound in dyspneic patients presenting to the ED. Selected studies underwent quality assessment using the Critical Appraisal and Skills Program (CASP) questionnaire.Data Extraction and SynthesisThe search yielded 3674 articles; seven studies met inclusion criteria and fulfilled CASP requirements for a total of 1861 patients. Summary statistics from the meta-analysis showed that as a diagnostic test for ADHF, bedside lung US had a pooled sensitivity of 82.5% (95% confidence interval [CI]=66.4% to 91.8%) and a pooled specificity of 83.6% (95% CI=72.4% to 90.8%).ConclusionsOur results suggest that in patients presenting to the ED with undifferentiated dyspnea, B-lines from early bedside lung US may be reliably used as an adjunct to current diagnostic methods. The incorporation of lung US may lead to more appropriate and timely diagnosis of patients with undifferentiated ADHF.

Abstract Introduction Dyspnea is the most frequent symptom of acute heart failure but it could also be a clinical presentation of some other noncardiogenic conditions. The differentiation of the origin of dyspnea could sometimes be a difficult task. The estimated elevation of left ventricle filling pressure with lung ultrasound proved positive B-lines score &gt; 15 could be reliable as diagnostic methods for acute decompensated heart failure and proof of the cardiogenic origin of dyspnea. Purpose To evaluate the reliability of elevated left ventricle filling pressure and positive lung ultrasound B-lines score in differentiation of the origin of dyspnea. Methods Elevated E/e´&gt;15 as a proof for elevated left ventricle filling pressure and multiple bilateral LUS B-lines (&gt;15) were tested against conventional X-ray and NT-proBNP in 44 patients with cardiogenic dyspnea (23 NYHA III patients and 21 NYHA IV patients) and 42 patients with noncardiogenic dyspnea. Results Elevated left ventricle filling pressure detected with echocardography (E/e´&gt;15) as a proof of acute decompensated heart failure was found in 18 NYHA IV patients and strongly correlated with multiple bilateral LUS B-lines &gt; 15 (all 21 NYHA IV patients), alveolar edema from conventional X-ray (21 NYHA IV patients) and NTproBNP &gt; 1000pg/ml in 17 NYHA IV patients. The results for NYHA III patients differ very much. Elevated filling pressure (E/e´ &gt; 15) from echocardiography was found in 10 patients NYHA III. For the left 13 patients NYHA III E/e´ was in grey zone between 8-14. Multiple bilateral LUS B-lines &gt;15 were found in 18 NYHA III patients. Interstitial pulmonary edema was found in 15 NYHA III patients and NTproBNP &gt; 1000pg/ml was found in 16 NYHA III patients. E/e´ between 8-14 (grey zone) moderately correlated with NT-proBNP and strongly with pulmonary blood flow redistribution and interstitial edema from X-ray. Normal left ventricle filling pressure (E/e´ &lt; 8) was found in 36 noncardiogenic patients. Only 6 patients with noncardiogenic dyspnea were with elevated left ventricle filling pressure (E/e´ &gt; 15) which was explained with their overweight (BMI &gt; 30) and hypervolemia and correlated with negative LUS B-lines. Only 1 patient with noncardiogenic dyspnea was with false positive B-lines score &gt; 15 typical for pneumonia. Conclusions Elevated left ventricle filling pressure detected with Tissue Doppler echocardiography (E/e´&gt;15) and positive LUS B-lines score &gt; 15 are reliable modalities for the diagnosis of cardiogenic dyspnea in patients NYHA IV. In patient NYHA III with cardiogenic dyspnea the two presented modalities proved to be with moderate reliability and need references from conventional X-ray and NT-proBNP.
