Increased neurohumoral stimulation resulting in excessive sodium avidity and extracellular volume overload are hallmark features of decompensated heart failure. Especially in case of concomitant renal dysfunction, the kidneys often fail to elicit effective natriuresis. While assessment of renal function is generally performed by measuring serum creatinine-a surrogate for glomerular filtration-, this only represents part of the nephron's function. Alterations in tubular sodium handling are at least equally important in the development of volume overload and congestion...

The European Society of Cardiology has recently published new guidelines on the diagnosis and treatment of acute and chronic heart failure (HF). This article aims to review these recommendations and their level of scientific evidence and to present the most innovative aspects. The most significant deviations from the 2012 edition are: 1) the introduction of the concept of HF with midrange LVEF (40-49%); 2) a new diagnostic algorithm for chronic HF, initially considering the clinical probability; 3) recommendations on preventing or delaying the apparition of HF; 4) indications for the use of the new sacubitril-valsartan compound, the first angiotensin receptor blocker and neprilysin inhibitor; 5) modification of indications for cardiac resynchronisation therapy; and 6) a new algorithm for a combined diagnostic and treatment strategy for acute HF based on the presence or absence of congestion and hypoperfusion...

PURPOSE OF REVIEW: As the number of people living with heart failure continues to grow, future treatments will focus on efficient donor organ donation and ensuring safe and durable outcomes. This review will focus on organ procurement, graft surveillance and emerging therapies. RECENT FINDINGS: Preliminary studies into donation after cardiac death have indicated that this may be an effective means to increase the donor pool. Novel preservation techniques that include ex-vivo perfusion to improve donor metabolic stabilization prior to implantation may also expand the donor pool...

BACKGROUND: Rheumatic heart disease (RHD) is an important and preventable cause of cardiovascular disease. OBJECTIVES: As part of a recent RHD initiative in Uganda and Tanzania, we systematically reviewed group A streptococcal disease (GAS), acute rheumatic fever (ARF), and RHD in these countries. METHODS: Using a systematic review and meta-analysis/meta-synthesis, we searched PubMed, Embase, and grey literature for quantitative and qualitative studies conducted in Uganda and Tanzania that included individuals affected by GAS, ARF, and RHD...

In the 19th century, cardio-active steroid glycosides, shortly cardiac glycosides, were scientifically established as drugs against heart failure. Their in vivo, cellular, and molecular actions as well as their predominant target, Na(+)-K(+)-ATPase, have been comprehensively investigated in the 20th century and the discovery of endogenous cardiac glycosides has fostered this research field. In the last years, however, results from clinical trials and meta-analyses have questioned their therapeutic value due to efficacy and safety issues...

The Cardiovascular Disease in Women Committee of the American College of Cardiology, in conjunction with interested parties (from the National Heart, Lung, and Blood Institute, American Heart Association, and European Society of Cardiology), convened a working group to develop a consensus on the syndrome of myocardial ischemia with no obstructive coronary arteries. In general, these patients have elevated risk for a cardiovascular event (including acute coronary syndrome, heart failure hospitalization, stroke, and repeat cardiovascular procedures) compared with reference subjects and appear to be at higher risk for development of heart failure with preserved ejection fraction...

Acute heart failure (HF) is a major public health problem with substantial associated economic costs. Because most patients who present to hospitals are admitted irrespective of their level of risk, novel approaches to manage acute HF are needed, such as the use of same-day access clinics for outpatient diuresis and observation units from the emergency department. Current published data lacks a comprehensive overview of the present state of acute HF management in various clinical settings. This review summarizes the strengths and limitations of acute HF care in the outpatient and emergency department settings...

B-type natriuretic peptides are markers of myocardial wall stress. BNP or NT-proBNP are used for the differential diagnosis of acute dyspnoe where normal serum concentrations make a cardiac cause unlikely. New data show their importance for risk prediction in different stages of heart failure and in primary prevention. Natriuretic peptide guided therapy improves titration of heart failure medications. Compared to BNP, NT-proBNP is better suited during therapy with the new angiotensin-rezeptor-neprilysin-inhibitor Sacubitril/Valsartan...

PURPOSE OF REVIEW: The goal of this article is to review potential expanded indications for neprilysin inhibitors. This article reviews the rationale and design for ongoing and future trials of sacubitril/valsartan in cardiovascular and non-cardiovascular disease. RECENT FINDINGS: Randomized trial data are lacking for use of sacubitril/valsartan in acute heart failure and advanced heart failure. Mechanistic data from animal studies suggest a role for neprilysin inhibition in the treatment of post-myocardial infarction systolic dysfunction and heart failure with preserved ejection fraction...

Acute decompensated heart failure (ADHF) contributes largely to the burden of heart failure and is associated with a poorer prognosis. Although numerous clinical trials evaluated the benefit of newer medications for ADHF, most of them were not successful. Areas covered: This review focusses on the updates on recent developments in chemical pharmacotherapy for the management of ADHF. A MEDLINE search for relevant review articles and original investigations on newer drugs for ADHF provided us with necessary literature...

Pathogenic Leptospira sp. are spirochetal bacteria responsible for leptospirosis, an emerging worldwide zoonosis. These spirochetes are very successful pathogens that infect a wide range of hosts such as fish, reptiles, birds, marsupials, and mammals. Transmission occurs when chronically infected animals excrete live bacteria in their urine, contaminating the environment. Leptospira sp. enter their hosts through damaged skin and mucosa. Chronically infected rats and mice are asymptomatic and are considered as important reservoirs of the disease...

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) frequently experience concurrent comorbidities; therefore, risk assessment for major adverse cardiovascular events (MACEs) is very important. OBJECTIVES: We explored the association between COPD and risk of MACEs with three common clinical events: acute myocardial infarction (AMI), ischemic stroke (IS), and cardiovascular death (CVD). METHODS: We evaluated the predictive value of the CHA2DS2-VASc score (congestive heart failure [C], hypertension [H), age [A], diabetes [D), stroke [S], and vascular disease [VASc]) for MACEs in COPD patients...

Heart failure (HF) is one of the leading causes of hospitalizations for elderly adults in the United States. One in 5 Americans will be >65 years of age by 2050. Because of the high prevalence of HF in this group, the number of Americans requiring hospitalization for this disorder is expected to rise significantly. We reviewed the most recent and ongoing studies and recommendations for the management of patients hospitalized due to decompensated HF. The Acute Decompensated Heart Failure National Registry, together with the 2013 American College of Cardiology Foundation and American Heart Association heart failure guidelines, earlier retrospective and prospective studies including the Diuretic Optimization Strategies Evaluation (DOSE), the Trial of Intensified vs Standard Medical Therapy in the Elderly Patients With Congestive Heart Failure (TIME-CHF), the Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF), the Rapid Emergency Department Heart Failure Outpatient Trial (REDHOT) and the Comparison of Medical, Pacing and Defibrillation Therapies in Heart Failure (COMPANION) trial were reviewed for current practices pertaining to these patients...

Blood-based biomarkers have been extensively studied in a range of cardiovascular diseases and have established utility in routine clinical care, most notably in the diagnosis of acute coronary syndrome (e.g., troponin) and the management of heart failure (e.g., brain-natriuretic peptide). The role of biomarkers is less well established in the management of valvular heart disease (VHD), in which the optimal timing of surgical intervention is often challenging. One promising biomarker that has been the subject of a number of recent VHD research studies is high sensitivity troponin (hs-cTn)...

Giampaolo Niccoli, Josip Anđelo Borovac, Vincenzo Vetrugno, Paolo G Camici, Filippo Crea
Ivabradine is a heart rate reducing agent that exhibits anti-ischemic effects through the inhibition of funny electrical current in the sinus node resulting in heart rate reduction, thus enabling longer diastolic perfusion time, and reduced myocardial oxygen consumption without detrimental changes in arterial blood pressure, coronary vasomotion, and ventricular contractility. The current guideline-based clinical use of Ivabradine is reserved for patients with stable angina pectoris who cannot tolerate or whose symptoms are inadequately controlled with beta blockers...

PURPOSE OF THE REVIEW: Infective endocarditis (IE) is a serious disease with significant morbidity and mortality. Valve surgery is fundamental in the standard of care of selected IE patients. Indeed, valve surgery can be a lifesaving procedure in critically ill endocarditis patients. Our goal from this review is to discuss the indications of surgery in IE population and international cardiac societies' guideline recommendations. RECENT FINDINGS: Though IE is an uncommon disease, its incidence is noted to be on rise in some parts of the world, and the disease is expected to continue to be a major health problem...

Milrinone is a phosphodiesterase 3 inhibitor with both positive inotropic and vasodilator properties. Administered as a continuous infusion, milrinone is indicated for the short-term treatment of patients with acute decompensated heart failure. Despite limited data supporting long-term milrinone therapy in adults with congestive heart failure, children managed as outpatients may benefit from continuous milrinone as a treatment for cardiac dysfunction, as a destination therapy for cardiac transplant, or as palliative therapy for cardiomyopathy...

BACKGROUND: One in three patients hospitalised due to acute exacerbation of COPD (AECOPD) is readmitted within 90 days. No tool has been developed specifically in this population to predict readmission or death. Clinicians are unable to identify patients at particular risk, yet resources to prevent readmission are allocated based on clinical judgement. METHODS: In participating hospitals, consecutive admissions of patients with AECOPD were identified by screening wards and reviewing coding records...
