Meta-Analysis of Point-of-Care Lung Ultrasonography Versus Chest Radiography in Adults With Symptoms of Acute Decompensated Heart Failure

Acute decompensated heart failure (ADHF) is a primary cause of older adults presenting to the emergency department with acute dyspnea. Point-of-care lung ultrasound (LUS) has shown comparable or superior diagnostic accuracy in comparison with a chest x-ray (CXR) in patients presenting with symptoms of ADHF. The systematic review and meta-analysis aimed to elucidate the sensitivity and specificity of LUS in comparison with CXR for diagnosing ADHF and summarize the rapidly growing body of evidence in this domain. A total of 5 databases were searched through February 18, 2021, to identify observational studies that reported on the use of LUS compared with CXR in diagnosing ADHF in patients presenting with shortness of breath. Meta-analysis was conducted on the sensitivities and specificities of each diagnostic method. A total of 8 studies reporting on 2,787 patients were included in this meta-analysis. For patients presenting with signs and symptoms of ADHF, LUS was found to be more sensitive than CXR (91.8% vs 76.5%) and more specific than CXR (92.3% vs 87.0%) for the detection of cardiogenic pulmonary edema. In conclusion, LUS is more sensitive and specific than CXR in detecting pulmonary edema. This highlights the importance of sonographic B-lines, along with the accurate interpretation of clinical data, in the diagnosis of ADHF. In addition to its convenience, reduced costs, and reduced radiation exposure, LUS should be considered an effective alternative to CXR for evaluating patients with dyspnea in the setting of ADHF.

Impact on Clinical Outcomes of Periodic Leg Movements During Sleep in Hospitalized Patients Following Acute Decompensated Heart Failure.

Periodic leg movements during sleep (PLM) are characterized by regularly recurring movement of the legs during sleep. Although PLM is common and a predictor of death in patients with chronic heart failure, the clinical significance of PLM in hospitalized patients with a reduced left ventricular ejection fraction (LVEF) following acute decompensated heart failure (ADHF) remains unknown.Methods and Results:After initial improvement of acute signs and symptoms of ADHF, 94 consecutive patients with reduced LVEF who underwent polysomnography were enrolled. They were divided into 2 groups based on the presence or absence of severe PLM defined as PLM index ≥30. The risks for clinical events, composite of all-cause death and rehospitalization, were assessed using a stepwise multivariable Cox proportional model including variables showing P<0.10 in univariate analyses. Severe PLM was observed in 21 patients (22%). At a median follow-up of 5.2 months, 30 patients experienced clinical events (32%). In the multivariable analysis, the presence of severe PLM was significantly associated with increasing clinical events (hazard ratio, 2.16; 95% confidence interval, 1.03-4.54; P=0.042) independent of hemoglobin level and the severity of sleep-disordered breathing. In hospitalized patients with systolic dysfunction following ADHF, severe PLM was prevalent and significantly associated with increased risk of death and/or rehospitalization.

Poor Flow-Mediated Dilation of Brachial Artery in Heart Transplant Recipients is Associated with Severity of Transplant Coronary Arterial Vasculopathy

Introduction: Periodic leg movements during sleep (PLM), regularly recurring movements of the legs during sleep, cause frequent arousal and intermittent eleva- tions of blood pressure and heart rate. One study showed that PLM disorder (PLMD) was associated with increased mortality in patients with chronic heart fail- ure. However, clinical significance of PLMD in hospitalized patients following acute decompensated heart failure (ADHF) remains unknown. Methods: After the initial improvement of acute signs and symptoms of ADHF, we performed polysomnogra- phy on consecutive patients who were left ventricular ejection fraction (LVEF) ! 50%, and were hospitalized due to ADHF between 2012 and 2014. PLMD was defined as PLM index S 25 that we thought was moderate-to-severe PLM. The risks for composite of all-cause mortality and re-hospitalization, were assessed by stepwise multivariable Cox proportional model including variables showing P!0.15 in univar- iate analyses. Results: Overall, 94 patients were enrolled. PLMD was found in 24 patients (26%). At a median follow-up of 5.2 months, 30 patients had an episode of rehospitalization and/or death (32%). In the multivariable analysis, presence of PLMD was significantly associated with increased risk of rehospitalization and/or mortality (hazard ratio, 2.34; P50.024) independent from hemoglobin level and severity of sleep disordered breathing. Conclusion: Presence of PLMD was indepen- dently associated with increased risk of rehospitalization and/or mortality even in hospitalized patient following ADHF.

Thoracic impedance vs chest radiograph to diagnose acute pulmonary edema in the ED

Objective We sought to investigate the relationship between thoracic impedance (Zo) and pulmonary edema on chest radiography in patients presenting to the emergency department (ED) with signs and symptoms of acute decompensated heart failure (ADHF). Design This was a prospective, blinded convenience sample of patients with signs and symptoms of ADHF who underwent measurement of Zo with concomitant chest radiography. Attending physicians blinded to the Zo values interpreted the radiographs, categorizing the severity of pulmonary edema as normal (NL), cephalization (CZ), interstitial edema (IE), or alveolar edema (AE). Intergroup comparisons were analyzed with a 2-way analysis of variance (ANOVA), with P < .05 considered statistically significant and reported using 95% confidence intervals (CIs). Setting We enrolled patients (≥18 years) presenting to a tertiary care medical center ED with signs and symptoms consistent with ADHF. Results A total of 203 patients were enrolled, with 27 (14%) excluded because of coexisting pulmonary diseases. The mean Zo values were inversely related to the 4 varying degrees of radiographic pulmonary vascular congestion as follows: NL, 25.6 (95% CI, 22.9-28.3); CZ, 20.8 (95% CI, 18.1-23.5); IE, 18.0 (95% CI, 16.3-19.7); and with AE, 14.5 (95% CI, 12.8-16.2) (ANOVA, P < .04). A Zo less than 19.0 ohms had 90% sensitivity and 94% specificity (likelihood ratio [LR], − 0.1; LR + 15) for identifying radiographic findings consistent with pulmonary edema. Females had an increased mean Zo value compared to males ( P < .03). Conclusion The Zo value obtained via thoracic bioimpedance monitoring accurately predicts the presence and severity of pulmonary edema found on initial chest radiograph in patients suspected of ADHF.

Hospitalized patients with acute decompensated heart failure: Recognition, risk stratification, and treatment review

Acute decompensated heart failure (ADHF) has emerged as a major healthcare problem. It causes approximately 3% of all hospitalizations in the United States, with the direct medical cost of these hospitalizations estimated at $18.8 billion per year. Early recognition, risk stratification, and evidence-based treatment are crucial in reducing the morbidity, mortality, and costs associated with this disorder. Classic signs and symptoms of ADHF, such as rales, dyspnea, and peripheral edema, may be absent at hospital presentation and, even when present, are not specific to this disorder. As a result, serum B-type natriuretic peptide level is now used to rapidly and accurately detect ADHF. Multivariate analyses have identified renal dysfunction, hypotension, advanced age, hyponatremia, and comorbidities as significant and independent mortality risk factors. Based on these factors, mortality risk can be stratified from very low to very high using published algorithms that have been validated in independent populations. Evidence-based guidelines for the treatment of ADHF are available from both the European Society of Cardiology and the Heart Failure Society of America. In general, an intravenous loop diuretic, either alone or in combination with a vasodilator, is recommended as initial therapy in patients with volume overload, depending on the patient's clinical status. Use of inotropic agents should be limited to the small subset of patients with low-output syndrome and significant hypotension. In any event, frequent monitoring of clinical response is essential, with subsequent therapy determined by this response. Finally, focused patient education during hospitalization may help reduce readmissions for ADHF.

Management of Acute Decompensated Heart Failure

Heart failure, a debilitating complex clinical syndrome, affects nearly 5 million people in the United States and presents a heavy socioeconomic burden. Neurohormonal abnormalities contribute to the pathophysiology of heart failure. Acute decompensated heart failure (ADHF) has emerged as a major health problem associated with poor prognosis, increased costs related to care, reduced quality of life, and frequent readmissions. Symptoms of ADHF are primarily related to congestion and/or low perfusion states. The use of biomakers such as B-natriuretic peptides is useful in distinguishing between cardiac and noncardiac causes of symptoms. Treatment for ADHF begins with identification and treatment of precipitating factors for acute decompensation. Initial goal of therapy is focused on symptom management followed by interventions that delay disease progression, reduce readmission, and prolong survival.
