Tolvaptan to Achieving High Urine Output and Avoiding Hyponatremia in COVID-19 with ADHF Patient: Case Report

Background: Pandemic of Coronavirus Disease 2019 (COVID-19) is a world health problem, with rapidly growing infected subjects. Recently, hyponatremia has been found to be associated with increased morbidity and mortality in hospitalized patients with severe acute respiratory syndrome-Coronavirus 2 (SARS-COV2) pneumonia. On the other hand, Acute heart failure (AHF) is a leading cause of hospitalization and readmission in the US. The standard management of AHF is removing the fluid primarily with loop diuretics or ultrafiltration. Unfortunately, the loop diuretics could lead to electrolyte imbalance.
 Case Description: A Male 71 years old with confirmed COVID-19 came to emergency room with shortness of breath and history of coronary artery disease (CAD). Unfortunately, the infection leads patient to non-ST Elevation Myocardial Infarction (NSTEMI). During the treatment, patient down to acute decompensated heart failure (ADHF). The congestion did not respond to Furosemide 40mg intravenously and Spironolactone 25mg orally.
 Discussion: Arginine‑vasopressin (AVP) levels are elevated in heart failure. AVP acts via V2 cause fluid retention and hyponatremia. Aquaretic (i.e., Tolvaptan) are antagonists of AVP-2 receptors in the renal tubules to promote solute-free water clearance and correct hyponatremia.
 Conclusion: Important to avoid hyponatremia to prevent mortality and sepsis in patient COVID-19.

Biomarkers in the management of acute heart failure: state of the art and role in COVID-19 era.

Acute heart failure (AHF) affects millions of people worldwide, and it is a potentially life‐threatening condition for which the cardiologist is more often brought into play. It is crucial to rapidly identify, among patients presenting with dyspnoea, those with AHF and to accurately stratify their risk, in order to define the appropriate setting of care, especially nowadays due to the coronavirus disease 2019 (COVID‐19) outbreak. Furthermore, with physical examination being limited by personal protective equipment, the use of new alternative diagnostic and prognostic tools could be of extreme importance. In this regard, usage of biomarkers, especially when combined (a multimarker approach) is beneficial for establishment of an accurate diagnosis, risk stratification and post‐discharge monitoring. This review highlights the use of both traditional biomarkers such as natriuretic peptides (NP) and troponin, and emerging biomarkers such as soluble suppression of tumourigenicity (sST2) and galectin‐3 (Gal‐3), from patients' emergency admission to discharge and follow‐up, to improve risk stratification and outcomes in terms of mortality and rehospitalization.

Long‐term outcomes after heart failure hospitalization during the COVID‐19 pandemic: a multisite report from heart failure referral centers in London

AimsPatients hospitalized for heart failure (HF) had worse in‐hospital outcomes during the first wave of the COVID‐19 pandemic. However, their long‐term outcomes are unknown. We describe long‐term outcomes among patients who survived to hospital discharge compared with patients hospitalized in 2019 from two referral centers in London during the COVID‐19 pandemic.Methods and resultsIn total, 512 patients who survived their hospitalization for acute HF in two South London referral centers between 7 January and 14 June 2020 were included in the study and compared with 725 patients from the corresponding period in 2019. The primary outcome was all‐cause mortality. The demographic characteristics of patients admitted in 2020 were similar to the 2019 cohort. Median (IQR) follow‐up was 622 (348–691) days. All‐cause mortality after discharge remained significantly higher for patients admitted in 2020 compared with the equivalent period in 2019 (P < 0.01), which may relate to observed differences in place of care with fewer patients being managed on specialist cardiology wards during the COVID‐19 pandemic.ConclusionHospitalization for HF during the first wave of the COVID‐19 pandemic was associated with higher all‐cause mortality among patients who survived to discharge. Further studies are necessary to identify predictors of these adverse outcomes to improve outpatient management during a critical period in the management of acute HF.

Acute heart failure in elderly patients: a review of invasive and non-invasive management

Acute heart failure (AHF) is a major cause of unplanned hospitalisations in the elderly and is associated with high mortality. Its prevalence has grown in the last years due to population aging and longer life expectancy of chronic heart failure patients. Although international societies have provided guidelines for the management of AHF in the general population, scientific evidence for geriatric patients is often lacking, as these are underrepresented in clinical trials. Elderly have a different risk profile with more comorbidities, disability, and frailty, leading to increased morbidity, longer recovery time, higher readmission rates, and higher mortality. Furthermore, therapeutic options are often limited, due to unfeasibility of invasive strategies, mechanical circulatory support and cardiac transplantation. Thus, the in-hospital management of AHF should be tailored to each patient’s clinical situation, cardiopulmonary condition and geriatric assessment. Palliative care should be considered in some cases, in order to avoid unnecessary diagnostics and/or treatments. After discharge, a strict follow-up through outpatient clinic or telemedicine is can improve quality of life and reduce rehospitalisation rates. The aim of this review is to offer an insight on current literature and provide a clinically oriented, patient-tailored approach regarding assessment, treatment and follow-up of elderly patients admitted for AHF.

Lung Ultrasound–Guided Emergency Department Management of Acute Heart Failure (BLUSHED-AHF): A Randomized Controlled Pilot Trial

ObjectivesThe goal of this study was to determine whether a 6-hour lung ultrasound (LUS)-guided strategy-of-care improves pulmonary congestion over usual management in the emergency department (ED) setting. A secondary goal was to explore whether early targeted intervention leads to improved outcomes. BackgroundTargeting pulmonary congestion in acute heart failure remains a key goal of care. LUS B-lines are a semi-quantitative assessment of pulmonary congestion. Whether B-lines decrease in patients with acute heart failure by targeting therapy is not well known. MethodsA multicenter, single-blind, ED-based, pilot trial randomized 130 patients to receive a 6-hour LUS-guided treatment strategy versus structured usual care. Patients were followed up throughout hospitalization and 90 days’ postdischarge. B-lines ≤15 at 6 h was the primary outcome, and days alive and out of hospital (DAOOH) at 30 days was the main exploratory outcome. ResultsNo significant difference in the proportion of patients with B-lines ≤15 at 6 hours (25.0% LUS vs 27.5% usual care; P = 0.83) or the number of B-lines at 6 hours (35.4 ± 26.8 LUS vs 34.3 ± 26.2 usual care; P = 0.82) was observed between groups. There were also no differences in DAOOH (21.3 ± 6.6 LUS vs 21.3 ± 7.1 usual care; P = 0.99). However, a significantly greater reduction in the number of B-lines was observed in LUS-guided patients compared with those receiving usual structured care during the first 48 hours (P = 0.04). ConclusionsIn this pilot trial, ED use of LUS to target pulmonary congestion conferred no benefit compared with usual care in reducing the number of B-lines at 6 hours or in 30 days DAOOH. However, LUS-guided patients had faster resolution of congestion during the initial 48 hours. (B-lines Lung Ultrasound–Guided ED Management of Acute Heart Failure Pilot Trial; NCT03136198)

Use of Extracorporeal Life Support for Heart Transplantation: Key Factors to Improve Outcome.

Although patients receiving extracorporeal life support (ECLS) as a bridge to transplantation have demonstrated worse outcomes than those without ECLS, we investigated the key factors in the improvement of their posttransplant outcome. From December 2003 to December 2018, 257 adult patients who underwent heart transplantation (HTx) at our institution were included. We identified 100 patients (38.9%) who underwent HTx during ECLS (ECLS group). The primary outcome was 30-day mortality after HTx. The median duration of ECLS was 10.0 days. The 30-day mortality rate was 3.9% (9.2% in peripheral ECLS, 2.9% in central ECLS, and 1.9% in non-ECLS). The use of ECLS was not an independent predictor of 30-day and 1-year mortality (p = 0.248 and p = 0.882, respectively). Independent predictors of 30-day mortality were found to be higher ejection fraction (p < 0.001), Sequential Organ Failure Assessment score (p < 0.001), and total bilirubin level (p = 0.005). In a subgroup analysis, cannulation type was not a predictor of 30-day mortality (p = 0.275). Early ECLS application to prevent organ failure and sophisticated management of acute heart failure may be important steps in achieving favorable survival after HTx.

Captopril Versus Hydralazine-Isosorbide Dinitrate Vasodilator Protocols in Patients With Acute Decompensated Heart Failure Transitioning From Sodium Nitroprusside

The role of oral vasodilators in the management of acute decompensated heart failure (ADHF) is not clearly defined. We evaluated the use of captopril vs hydralazine-isosorbide dinitrate (H-ISDN) in the transition from sodium nitroprusside (SNP) in patients with ADHF. A retrospective chart review was performed of 369 consecutive adult patients in the intensive care unit with ADHF and reduced ejection fraction, who received either a captopril or an H-ISDN protocol to transition from SNP. Captopril patients were matched 1:2 to H-ISDN patients, based on serum creatinine and race (Black vs non-Black). Baseline demographics, serum chemistry and use of angiotensin converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) were similar in both groups. Time to SNP discontinuation (46.9 vs 40.4 hours, P = 0.11) and length of hospital stay (9.86 vs 7.99 days, P = 0.064) were similar in both groups. Length of hospital stay in the intensive care unit was statistically shorter in the H-ISDN group (4.11 vs 3.96 days, P = 0.038). Fewer H-ISDN protocol patients were discharged on ACEis/ARBs (82.9 % vs 69.9%, P = 0.003) despite similar kidney function at time of discharge (serum creatinine 1.1 vs 1.2, P = 0.113). No difference was observed in rates of readmission (40.7% vs 50%, P = 0.09) or mortality (16.3% vs 17.5 %, P = 0.77) at 1 year postdischarge. Similar inpatient and 1-year outcomes were observed between patients using H-ISDN vs ACEi when transitioning from SNP, even though fewer H-ISDN protocol patients were discharged taking ACEis/ARBs despite similar kidney function.

Cardiovascular outcomes of ferric carboxymaltose supplementation for the management of iron-deficient acute and chronic heart failure- a meta analysis

Abstract Funding Acknowledgements Type of funding sources: None. Background-Iron deficiency is prevalent in heart failure patients and is associated with unfavorable clinical outcomes, irrespective of anemia status. The 2016 European Society of Cardiology (ESC) guidelines recommended intravenous ferric carboxymaltose (FCM) for the management of acute and chronic heart failure in symptomatic HF with reduced ejection fraction (EF). Objective- To determine whether the correction of iron deficiency with ferric carboxymaltose confers better clinical outcomes in patients with acute and chronic heart failure Methods-Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to December 28th, 2020. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p &amp;lt; 0.05. The primary outcome of interest was cardiac mortality. Secondary outcomes included first hospitalisation due to worsening heart failure and any other cardiovascular (CV) reason. Results-A total of five studies with 2091( FCM = 1125; placebo = 966) patients were included. Average follow-up period was 2 years. There was no difference in terms of cardiac mortality (RR 0.93, 95% CI 0.71–1.21; p = 0.57; I2 = 0) and hospitalizations for any CV reason (RR 0.83, 95% CI 0.32–2.16; p = 0.70; I2 = 83) with either group at the end of follow-up. As compared to placebo, FCM was associated with significant reduction in hospitalization due to worsening heart failure (RR 0.64; 95% CI 0.41-0.99; p = 0.04; I2 = 56) Conclusion- Amongst patients with iron-deficient acute and chronic heart failure, treatment with ferric carboxymaltose reduced the risk of heart failure hospitalizations, with no apparent effect on the risk of cardiac mortality and hospitalizations for any other CV cause.

Association between early intensive care or coronary care unit admission and post-discharge performance of activities of daily living in patients with acute decompensated heart failure.

The management of acute decompensated heart failure often requires intensive care. However, the effects of early intensive care unit/coronary care unit admission on activities of daily living (ADL) in acute decompensated heart failure patients have not been precisely evaluated. Thus, we retrospectively assessed the association between early intensive care unit admission and post-discharge ADL performance in these patients. Acute decompensated heart failure patients (New York Heart Association I–III) admitted on emergency between April 1, 2014, and December 31, 2018, were selected from the Diagnosis Procedure Combination database and divided into intensive care unit/coronary care unit (ICU) and general ward (GW) groups according to the hospitalization type on admission day 1. The propensity score was calculated to create matched cohorts where admission style (intensive care unit/coronary care unit admission) was independent of measured baseline confounding factors, including ADL at admission. The primary outcome was ADL performance level at discharge (post-ADL) defined according to the Barthel index. Secondary outcomes included length of stay and total hospitalization cost (expense). Overall, 12231 patients were eligible, and propensity score matching created 2985 pairs. After matching, post-ADL was significantly higher in the ICU group than in the GW group [mean (standard deviation), GW vs. ICU: 71.5 (35.3) vs. 78.2 (31.2) points, P<0.001; mean difference: 6.7 (95% confidence interval, 5.1–8.4) points]. After matching, length of stay was significantly shorter and expenses were significantly higher in the ICU group than in the GW group. Stratified analysis showed that the patients with low ADL at admission (Barthel index score <60) were the most benefited from early intensive care unit/coronary care unit admission. Thus, early intensive care unit/coronary care unit admission was associated with improved post-ADL in patients with emergency acute decompensated heart failure admission.

Good performance in the management of acute heart failure in cardiogeriatric departments: the ICREX-94 experience

ContextA growing number of elderly patients hospitalized for Acute Heart Failure (AHF) are being managed in cardiogeriatrics departments, but their characteristics and prognosis are poorly known. This study aimed to investigate the profile and outcome (rehospitalization at 90 days) of patients hospitalized for AHF in cardiogeriatrics departments in the Val-de-Marne area in the suburbs of Paris, and to compare them to AHF patients hospitalized in cardiology departments in the same area.MethodsObservational study, ICREX-94, conducted in seven cardiology departments in France and three specific cardiogeriatrics departments in Val-de-Marne.ResultsA total of 308 patients were hospitalized for AHF between October 2017 and January 2019. During the 90 days following discharge, 29.6% patients were readmitted to the hospital. Compared with patients hospitalized in cardiology departments, patients in cardiogeriatrics departments were older (p < 0.001), less independent (living more often alone or in an institution) (p < 0.001), more often depressed (p < 0.001), had more often major neurocognitive disorder (p < 0.001), had a higher Human Development Index (HDI, p < 0.001), and were less often diagnosed with amyloidosis (p < 0.001). There was no difference in outcome whether patients were discharged from cardiology or cardiogeriatrics departments. The most frequent precipitating factors underlying AHF decompensation between the first and second hospitalization were arrhythmia and infection.ConclusionAHF patients discharged from cardiogeriatrics departments, compared to cardiology departments, showed clinical differences but had the same prognosis regarding AHF rehospitalization at 90 days.

An Update of Armamentarium for Non Invasive Cardiac Haemodynamics and Congestion Evaluation for Acute Heart Failure Patients

In the management of Acute Heart Failure(AHF) patients ,current guidelines suggest to make a prompt clinical assessments that include patient’s congestion and perfusion status evaluation, in order to start appropriate treatments. Unfortunately ,so far, an accurate evaluation of haemodynamic and fluid status of AHF patients is only possible using invasive methods ;conseguently there is an unmeet need for noninvasive technologies to easly detect different phenotypes of AHF subjects based on different cardiac haemodynamic profiles . Technological advances such as: Biva,Nexfin or NICas could allow for routine noninvasive continuous monitoring of Cardiac Hemodymanics and Fluid content in Acute Heart Failure patients. These non invasive measurements may provide important information for improving diagnosis, developing individualized therapeutic management plans/disposition decisions and predicting short term mortality

Disease Management and Outcomes in Patients Hospitalized for Acute Heart Failure in Japan.

IntroductionThis study described patients hospitalized for acute heart failure (AHF) in Japan who received intravenous (IV) diuretics and/or vasodilators as the initial therapy.MethodsThe Japan Medical Data Vision database was used to identify adult patients hospitalized for AHF during 2013–2017, who were hemodynamically stable at presentation and treated with IV diuretics and/or IV vasodilators as initial therapy. Treatment patterns and use of cardiac rehabilitation, as well as outcomes (e.g., length of stay [LOS], in-hospital mortality, HF-readmission) were reported overall and by year of AHF hospitalization.ResultsOf 30,360 patients (mean age = 80.0 years; 52.2% male), 87.0% were treated during the hospitalization with IV diuretics, 63.9% with IV vasodilators, and 13.8% with intensified therapies. On average, the duration of IV therapy was 10.6 days. In-hospital cardiac rehabilitation was utilized by 51.7% of the patients for 11.7 days on average. Mean LOS was 23.3 days, while in-hospital mortality and 30-day HF readmission post-discharge were 13.2 and 9.5%, respectively. Hospitalization outcomes remained stable between 2013 and 2017 despite important changes in AHF management such as a decrease in carperitide use (55.9–40.0% in 2017), and increases in use of tolvaptan (from 14.2% in 2013 to 31.3% in 2017) and of cardiac rehabilitation (from 43.2% in 2013 to 56.1% in 2017). Patients with intensified therapies had the longest IV therapy duration (mean 23.8 days vs. 5.5–9.9 days), the highest cardiac rehabilitation services use (60.2 vs. 38.3–57.0%), the longest LOS (mean 36.7 vs. 16.3–22.2 days), and the highest in-hospital mortality (37.4 vs. 3.1–12.4%) compared to the other treatment groups.ConclusionsContemporary treatment for AHF hospitalization in Japan comprises a long duration of IV therapy followed by extended use of oral medications and in-hospital cardiac rehabilitation prior to discharge. Patients requiring intensified therapies had much longer LOS and higher in-hospital mortality.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40119-021-00212-y.

Medical management of pediatric heart failure.

Pediatric heart failure is a complex, heterogenous syndrome that occurs relatively rarely in children, but carries a high burden of morbidity and mortality. This article reflects on the current state of medical therapy for both acute and chronic pediatric heart failure, based on expert consensus guidelines, and the extrapolation of data from trials performed in adults. For the management of acute heart failure specifically, we rely on an initial assessment of the perfusion and volume status of a patient, to guide medical therapy. This paradigm was adapted from adult studies that demonstrated increased morbidity and mortality in heart failure patients whose hemodynamics or examination findings were consistent with a PCWP >18 mmHg and a CI ≤2.2 L/min/m2. The cornerstone of treatment in the acute setting therefore relies on achieving a euvolemic state with adequate cardiac output. In the chronic setting, patients are typically maintained on a regimen of an angiotensin converting enzyme inhibitor, a beta-blocker, and spironolactone. For those with refractory heart failure, intravenous milrinone therapy has become a mainstay of bridging children to cardiac transplantation. The pediatric-specific data driving these clinical practices are limited and often times, conflicting. The future of pediatric heart failure depends on collaboration, quality improvement, and a commitment to pediatric-specific indications for new medical and device therapies.

Blood Pressure Reduction in Hypertensive Acute Heart Failure.

To review the key clinical and research questions regarding blood pressure (BP) reduction with vasodilators in the early management of hypertensive acute heart failure (H-AHF). Despite numerous AHF vasodilator clinical trials in the past two decades, virtually none has studied a population where vasoconstriction is the predominant physiology, and with the agents and doses most commonly used in contemporary practice. AHF patients are remarkably heterogenous by vascular tone, and this heterogeneity is not always discernible through BP or clinical exam. Emerging data suggest that diastolic BP may be a stronger correlate of vascular tone in AHF than systolic BP, despite the latter historically serving as a key inclusion criterion for vasodilator clinical trials. Existing data are limited. A clinical trial that evaluates vasodilators in a manner of use consistent with contemporary practice, specifically within the subpopulation of patients with true H-AHF, is greatly needed. Until then, observational data supports long-standing vasodilators such as nitroglycerin, administered by IV bolus, and with goal reduction of SBP ≤25% as a safe first-line approach for patients with severe H-AHF presentations.

Atrial Natriuretic Peptide: Structure, Function, and Physiological Effects: A Narrative Review.

Atrial natriuretic peptide (ANP) is a cardiac peptide with multiple physiological effects, including natriuresis, blood pressure regulation, and renin-angiotensin-aldosterone system (RAAS) antagonism. Pre-proANP is synthesized in the atria and must be extensively cleaved by the protease corin to produce the mature 28 amino acid ANP. The downstream signaling pathway of ANP acts through the guanylyl cyclase receptor and the second messenger cGMP. Studies on ANP's physiological effects have demonstrated its activity on channels present in the apical membrane in the renal nephron, potentially inhibiting or decreasing sodium reabsorption. Recent research has also identified several clinical conditions, such as dilated cardiomyopathy, renal failure, and aging, associated with increased and decreased ANP levels. ANP levels could serve as a potential biomarker for the diagnosis of acute stages of heart failure, and ANP infusion could have a role in the management of acute or chronic heart failure.

Brief intensive observation areas in the management of acute heart failure in elderly patients leading to high stabilisation rate and less admissions

Objectives. Acute heart failure is major cause of hospitalisation in Western countries. As patients with acute heart failure cannot be admitted directly to the wards, they stay in emergency rooms, causing access block. Brief Intensive Observation areas are holding units dedicated to the stabilisation of patients requiring close monitoring. However, these units have been associated with acute exacerbation of heart failure. This study aimed to evaluate the impact of Brief Intensive Observation areas on the management of acute heart failure in elderly patients. Methods. This retrospective, single-centred observational study analysed patients who presented in the emergency room with acute heart failure in 2017 and divided them into two cohorts: those treated in the Brief Intensive Observation and those who were not. The reduction of colour codes at discharge, mortality rate within the emergency rooms, hospitalisation rate, rate of transfer to less intensive facilities and readmission rate at 7, 14 and 30 days after discharge were compared. Results. Of the 694 patients, 62% were transferred to the Brief Intensive Observation for stabilisation. Age and sex between the cohorts were not significantly different. However, compared to non-Brief Intensive Observation patients, the Brief Intensive Observation patients had worse clinical conditions on arrival and longer stabilisation period. The stabilisation rate was higher in Brief Intensive Observation patients than in non-Brief Intensive Observation patients. Conclusions. Brief Intensive Observation areas allows effective stabilisation of elderly patients, better management of beds, reduced admission rates and reduced use of high intensity care unit beds.

Role of transthoracic echocardiogram in acute heart failure.

Acute Heart Failure (AHF) is an increasingly common condition with a poor prognosis. In contrast to CHF where advances in medical therapy and devices has led to significant improvement in morbidity and mortality, the prognosis for AHF has not changed significantly in the last few decades despite efforts to find effective treatment. There are multiple factors that contribute to the high mortality and morbidity of AHF; it can be a diagnostic challenge, determining whether decongestion has been achieved can be difficult, and persisting congestion is commonly present at discharge contributing to early decompensation and rehospitalisation. Transthoracic echocardiogram (TTE) is a unique imaging modality that is non-invasive, can be done at the bedside, in real time during procedures, is affordable and easy to access both in community and inpatient settings. Small hand held 'point of care' scans are increasingly available and being used as an adjunct to improve clinical examination. Consequently, the use of echocardiography to improve outcomes for patients with cardiac disease continues to evolve. In chronic heart failure TTE has established roles in the quantification of HF phenotype, and determination of treatment initiation, escalation and success. However, the role of echocardiogram in AHF is not as well established with society guidelines relying on expert consensus for their recommendations. Use of TTE at all stages of AHF has potential to reduce morbidity and mortality. This review discusses the evidence for use of TTE to improve the diagnosis, prognosis and management of AHF.

Biomarkers in Acute Heart Failure: Diagnosis, Prognosis, and Treatment.

Heart failure is a global health problem. An episode of acute heart failure (AHF) is a period of substantial morbidity and mortality with few advances in the management of an episode that have improved outcomes. The measurement of multiple biomarkers has become an integral adjunctive tool for the management of AHF. Many biomarkers are now well established in their ability to assist with diagnosis and prognostication of an AHF patient. There are also emerging biomarkers that are showing significant promise in the areas of diagnosis and prognosis. For improving the management of AHF, both established and novel biomarkers may assist in guiding medical therapy and subsequently improving outcomes. Thus, it is important to understand the different abilities and limitations of established and emerging biomarkers in AHF so that they may be correctly interpreted and integrated into clinical practice for AHF. This knowledge may improve the care of AHF patients. This review will summarize the evidence of both established and novel biomarkers for diagnosis, prognosis and management in AHF so that the treating clinician may become more comfortable incorporating these biomarkers into clinical practice in an evidence-based manner.

Impact of daily bedside echocardiographic assessment on readmissions in acute heart failure: The JECICA randomized trial

Acute Heart Failure (AHF) management is challenging, with high morbidity and readmission rates. There is little evidence of the benefit of HF monitoring during hospitalization. We hypothesized that a fast, daily bedside echocardiographic assessment (JetEcho) would improve therapeutic adjustment and outcome. In this prospective, open, two parallel-arm randomized study, 248 patients hospitalized for AHF were assigned to either JetEcho aimed to achieve normal left ventricular filling pressure (LVFP) and volemia, or standard care (SC). The primary outcome was the 30-day readmission rate. Key secondary outcomes were readmission and mortality rates at six months. The primary outcome occurred in 22 of 115 patients (19%) in the JetEcho group and in 17 of 112 patients (15%) in the SC group (relative risk [RR] 1.26; 95% confidence interval [CI], 0.70–2.24; P = 0.4). Six-month readmission rate for cardiac or renal causes was lower in the JetEcho group [ N = 23 (21%)] versus the SC group [ N = 38 (36%)] (RR 0.58; 95%CI, 0.37–0.90; P = 0.01). Six-month mortality did not differ [HR 0.63 (95% CI; 0.3–1.4) P = 0.3] ( Table 1 ) ( Fig. 1 ). The study found no benefit of bedside echography in reducing 30-day readmission rate. However, readmissions for cardiac and renal causes was lower at six months in the JetEcho group, suggesting delayed beneficial effects.

The inodilator levosimendan: 20 years of experience in various settings of cardiac care

Levosimendan emerged in the 1990s as a first-in-class inotrope and vasodilator that enhances cardiac contractility by sensitizing the contractile response to cardiac troponin C and causes vasodilatation by opening potassium-dependent ATP channels on vascular smooth muscle cells. Since its clinical debut in 2000, it has established itself as a valuable resource in the management of acute decompensated heart failure and is one of very few successful medical innovations of its kind in that field in recent decades. Its pharmacology is notable for delivering inotropy without an increase in myocardial oxygen consumption and for an array of secondary (‘pleiotropic’) effects that include an anti-ischemic effect, pre-conditioning and post-conditioning and cardioprotective effects and anti-oxidative effects. Proceeding from those properties it has been proposed that in addition to its use in various scenarios of low cardiac output levosimendan may be beneficial in other conditions associated with acutely decompensated heart failure, including right ventricular failure, subarachnoid hemorrhage, and cardiogenic shock with multi-organ dysfunction. The potential of levosimendan for kidney protection in situations of the cardio-renal syndrome has been identified. Additional lines of investigation include the use of levosimendan for perioperative hemodynamic support, its administration as repeated intermittent infusions to sustain patients with advanced heart failure and its application in a range of critical care settings. Levosimendan has also provided a template and a starting point for the development of a new generation of cardio-active drugs and is currently being evaluated in advanced clinical trials for the management of pulmonary hypertension in patients with heart failure with preserved ejection fraction.
