Acute heart failure is a major and growing public health problem worldwide with high morbidity, mortality, and cost. Despite recent advances in pharmacological management, the prognosis of patients with acute decompensated heart failure remains poor. Consequently, nonpharmacological approaches are being developed and increasingly used. Such techniques may include several modalities of ventilation, ultrafiltration, mechanical circulatory support, myocardial revascularization, and surgical treatment, among others. This document reviews the nonpharmacological approach in acute heart failure, indications, and prognostic implications.

Acute heart failure is a symptom complex of heterogeneous etiology. Clinically, it comprises a broad spectrum ranging from hypertensive pulmonary edema in patients with preserved left ventricular systolic function up to cardiogenic shock in patients with severely depressed left ventricular function. The pathophysiology of acute heart failure is based on a mismatch between myocardial pump function and afterload. Besides causal measures, vasodilators and diuretics are the mainstay of therapy. Catecholamines are indicated only when other drugs are unsuccessful. Opioids are often used in clinical practice but should be used cautiously as they are associated with a negative prognosis. Further adjunctive treatment consists of thromboembolism prophylaxis, non-invasive ventilation and in some cases mechanical circulatory support and renal replacement therapy. This article discusses the differential use of these treatment modalities.

Acute heart failure remains a major cause of morbidity, and its treatment requires an increasing investment of the health care system. Whereas success in treating chronic heart failure has been achieved over the last decades, several pharmacological approaches for acute heart failure have been introduced but have failed to demonstrate any clinical benefit. Serelaxin is a recombinant human relaxin-2 vasoactive peptide that causes systemic and renal vasodilation. Data suggest that the clinical benefits may be attributable to a potential combination of multiple actions of serelaxin, including improving systemic, cardiac, and renal hemodynamics, and protecting cells and organs from damage via neurohormonal, anti-inflammatory, antiremodeling, antifibrotic, anti-ischemic, and proangiogenic effects. Recently, a number of clinical trials have demonstrated that serelaxin infusion over 48 hours improved dyspnea with more rapid relief of congestion during the first days after admission for heart failure. In addition, administration of serelaxin diminished cardiac, renal, and hepatic damage, which were associated with improved long-term mortality. Available data support substantial clinical benefits and significant promise for serelaxin as a treatment option for patients with acute heart failure. This review focuses on the pharmacology and mechanisms of action of serelaxin and provides a detailed discussion of the clinical evidence for this novel therapy in acute heart failure.

Acute heart failure (AHF) is a complex syndrome characterized by worsening heart failure (HF) symptoms that requires escalation of therapy. Intrinsic cardiac abnormalities and comorbid conditions, including lung and renal disease, and sleep-disordered breathing, can contribute to the development of AHF. In this Review, we summarize and discuss the literature on the clinical evaluation and underlying pathophysiology of AHF. Important features of AHF evaluation include identification of precipitating factors to the disease, and assessment of circulatory-renal limitations associated with use of HF medications, prior HF hospitalizations, congestion and perfusion profiles, and end-organ dysfunction. The pathophysiological contributions of endothelial dysfunction, neurohormonal activation, venous congestion, and myocardial injury to the development of AHF are also discussed. These potential causative mechanisms provide a framework for clinicians to evaluate and manage patients with AHF and highlight possible future targets for therapies designed to improve clinical outcomes.

Acute heart failure is a common and serious complication of congenital and acquired heart disease, and it is associated with significant morbidity, mortality, and costs. When a patient is admitted to the hospital with acute heart failure, there are several important goals for the hospital admission, including maintaining adequate perfusion, establishing the underlying aetiology for the heart failure, patient and family education, and discharge from the hospital in a stable condition. The pathway to home discharge is variable and may include inotropic therapy, mechanical circulatory support, and/or heart transplantation. This review will cover the epidemiology, presentation, and management of acute heart failure in children.

Acute heart failure describes the rapid deterioration, over minutes, days or hours, of symptoms and signs of heart failure. Its management is an interdisciplinary challenge that requires the cooperation of various specialists. While emergency providers, (interventional) cardiologists, heart surgeons, and intensive care specialists collaborate in the initial stabilization of acute heart failure patients, the involvement of nurses, discharge managers, and general practitioners in the heart failure team may facilitate the transition from inpatient care to the outpatient setting and improve acute heart failure readmission rates. This review highlights the importance of a multidisciplinary approach to acute heart failure with particular focus on the chain-of-care delivered by the various services within the healthcare system.

Acute heart failure is a prognostic factor due to its high mortality during the acute phase and the increased frequency of medium to long-term adverse events. The pathophysiological mechanisms triggered during these exacerbations can persist after reaching clinical stability, remaining even after the acute episode has ended. A certain degree of neurohormonal activation, oxidative stress, apoptosis and inflammation (among other conditions) can therefore persist, resulting in organ damage, not just of the myocardium but likely the entire cardiovascular apparatus. This new insight into the persistence of harmful mechanisms that last beyond the exacerbations could be the start of a change in perspective for developing new therapeutic strategies that seek an overall control of hemodynamic and congestive changes that occur during acute decompensated heart failure and changes that remain after achieving clinical stability.

Acute heart failure (AHF) in the elderly is an increasingly common clinical problem associated with high in-hospital, short- and long-term mortality rates worldwide. Elderly patients with AHF have different clinical and pathophysiological profiles compared with younger ones. Prevalent cardiovascular comorbidities in the elderly are arterial hypertension and atrial fibrillation, whereas ischemic heart disease and associated risk factors are more common in younger patients. There is a need for greater dissemination of heart failure guidelines and for involvement of multidisciplinary teams for optimizing treatment and eliminating disparities in care in this vulnerable patient group across both sides of the Atlantic.

Hospitalization for heart failure (HHF) is a frequent manifestation of chronic heart failure (CHF), and represents the moment of greatest impact on costs and on risk for the patient, in particular after discharge. Contributing factors to this disappointingly high postdischarge event rate include the incomplete relief of fluid overload, insufficient patient education, the lack of implementation of evidence-based therapies, poor follow-up and inadequate risk stratification before leaving hospital. Among available tools, different biomarkers have been tested, including cardiac troponin (cTn). The value of cTn to monitoring and to stratifying risk before discharge has been evaluated by mean of three strategies: a single measurement before discharge, monitoring with serial sampling during hospitalization, and comparing admission and predischarge values to establishing the cTn "delta". Acute heart failure syndrome (AHFS) is an active and continuing process, which starts at admission, but its evolution might be unpredictable, and the prevention of ongoing myocardial damage (OMD) might be one of the important targets to improve prognosis. OMD is also a dynamic process and can be detected in CHF and HHF, at different moments and in diverse magnitudes, justifying the cTn monitoring. The favorable effect of drugs on cTn release and its association with better prognosis have increased our expectation for the role of serial determination in HHF patients.

Acute heart failure is a leading cause of hospitalization and death, and it is an increasing burden on health care systems. The correct risk stratification of patients could improve clinical outcome and resources allocation, avoiding the overtreatment of low-risk subjects or the early, inappropriate discharge of high-risk patients. Many clinical scores have been derived and validated for in-hospital and post-discharge survival; predictive models include demographic, clinical, hemodynamic and laboratory variables. Data sets are derived from public registries, clinical trials, and retrospective data. Most models show a good capacity to discriminate patients who reach major clinical end-points, with C-indices generally higher than 0.70, but their applicability in real-world populations has been seldom evaluated. No study has evaluated if the use of risk score-based stratification might improve patient outcome. Some variables (age, blood pressure, sodium concentration, renal function) recur in most scores and should always be considered when evaluating the risk of an individual patient hospitalized for acute heart failure. Future studies will evaluate the emerging role of plasma biomarkers.
