Immune activation and inflammation participate in the progression of chronic heart failure (CHF). Th17 cells and CD4+CD25+ regulatory T (Treg) cells both come from naive Th cells and share reciprocal development pathways but exhibit opposite effects. We hypothesized that the Th17/Treg balance was impaired in patients with CHF, and exercise can improve it.

Heart failure (HF) is a common cardiac syndrome, whose pathophysiology involves complex mechanisms, some of which remain unknown. Diabetes mellitus (DM) constitutes not only a glucose metabolic disorder accompanied by insulin resistance but also a risk factor for cardiovascular disease and HF. During the last years though emerging data set up, a bidirectional interrelationship between these two entities.

Severe right ventricular (RV) failure is more likely reversible than similar magnitudes of left ventricular (LV) failure and, because reversal of both adaptive remodeling and impaired contractility require most often only short periods of support, the use of temporary RV assist devices (t-RVADs) can be a life-saving therapy option for many patients. Although increased experience with t-RVADs and progresses made in the development of safer devices with lower risk for complications has improved both recovery rate of RV function and patient survival, the mortality of t-RVAD recipients can still be high but it depends mainly on the primary cause of RV failure (RVF), the severity of end-organ dysfunction, and the timing of RVAD implantation, and much less on adverse events and complications related to RVAD implantation, support, or removal. Reduced survival of RVAD recipients should therefore not discourage appropriate application of RVADs because their underuse further reduces the chances for RV recovery and patient survival.

Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality.

Regardless of advances in medical and interventional treatment of cardiovascular disease (CVD), a limited number of patients attend a cardiac rehabilitation (CR) programme on a regular basis. Due to modern therapies more individuals will be surviving an acute cardiovascular event, but the expected burden of chronic heart failure will be increasing worldwide.However, both in high- and low-income countries, secondary prevention after an acute myocardial infarction or stroke has been implemented in less than a half of eligible patients.

Composite endpoints combining several event types of clinical interest often define the primary efficacy outcome in cardiologic trials. They are commonly evaluated as time-to-first-event, thereby following the recommendations of regulatory agencies. However, to assess the patient's full disease burden and to identify preventive factors or interventions, subsequent events following the first one should be considered as well.

Despite the successes from refined peri-operative management techniques and immunosuppressive therapies, antibodies remain a serious cause of morbidity and mortality for patients both before and after heart transplantation. Patients awaiting transplant who possess antibodies against human leukocyte antigen are disadvantaged by having to wait longer to receive an organ from a suitably matched donor. The number of pre-sensitized patients has been increasing, a trend that is likely due to the increased use of mechanical circulatory support devices.

Heart failure is a complex disease, which is presented differently by men and women. Several studies have shown that reproductive factors, such as age at natural menopause, parity and polycystic ovarian syndrome (PCOS), may play a role in the development of heart failure. Shared genetics may provide clues to underlying mechanisms; however, this has never been examined.

Nucleic acid (NA)-sensing Toll-like receptors (TLRs) respond to DNA/RNA derived from pathogens and dead cells. Structural studies have revealed a variety of molecular mechanisms by which TLRs sense NAs. Double-stranded RNA and single-stranded DNA directly bind to TLR3 and TLR9, respectively, whereas TLR7 and 8 bind to nucleosides and oligoribonucleotides derived from RNAs.

Protein O-fucosyltransferase-1 (POFUT1) adds O-fucose monosaccharides to epidermal growth factor-like (EGF) repeats found on approximately 100 mammalian proteins, including Notch receptors. Haploinsufficiency of POFUT1 has been linked to adult-onset Dowling Degos Disease (DDD) with hyperpigmentation defects. Homozygous deletion of mouse Pofut1 results in embryonic lethality with severe Notch-like phenotypes including defects in somitogenesis, cardiogenesis, vasculogenesis, and neurogenesis, but the extent to which POFUT1 is required for normal human development is not yet understood.

It is unclear whether non-invasive screening of asymptomatic diabetic patients for coronary artery disease (CAD) may improve cardiac outcomes. Thus, we performed a systematic literature review and meta-analysis of randomised controlled trials (RCT's) on this topic. We searched appropriate RCT's in five online databases (PubMed/MEDLINE, Cochrane Library, Embase, Scopus, and Web of Science) from January 2000 to November 2017 and in 41 recent reviews.

Cardiac Resynchronization Therapy (CRT) is an established therapeutic option for the subset of patients with heart failure (HF), reduced ejection fraction (EF) and dyssynchrony evidenced by electrocardiography. Benefit from CRT has been proven in many clinical trials, yet a sizeable proportion of these patients with wide QRS do not respond to this intervention, despite the updated practice guidelines. Several echocardiographic indices, targeting mechanical rather than electrical dyssynchrony, have been suggested to address this issue, but research so far has not succeeded in providing a single and simple measurement with adequate sensitivity and specificity for identification of responders.

Bioengineering of a functional cardiac tissue composed of primary cardiomyocytes has great potential for myocardial regeneration and in vitro tissue modeling. However, its applications remain limited because the cardiac tissue is a highly organized structure with unique physiologic, biomechanical, and electrical properties. In this study, we undertook a proof-of-concept study to develop a contractile cardiac tissue with cellular organization, uniformity, and scalability by using three-dimensional (3D) bioprinting strategy.

Hypertrophic cardiomyopathy (HCM) is frequently linked to mutations in the protein components of the myosin-containing thick filaments leading to contractile dysfunction and ultimately heart failure. However, the molecular structure-function relationships that underlie these pathological effects remain largely obscure. Here we chose an example mutation (R58Q) in the myosin regulatory light chain (RLC) that is associated with a severe HCM phenotype and combined the results from a wide range of in vitro and in situ structural and functional studies on isolated protein components, myofibrils and ventricular trabeculae to create an extensive map of structure-function relationships.

Depressive symptoms and physical frailty have been reported to be predictive of adverse outcomes in individuals with heart failure (HF). Depressive symptoms could be a predisposing factor of physical frailty in older adults. Despite the high prevalence of HF, few studies on the relationship between these two factors have been performed in older adults with HF.

Mutations in genes encoding components of sarcomere cause cardiomyopathy, which is often associated with abnormal Casensitivity of muscle contraction. We previously showed that a heart-specific myosin light chain phosphatase small subunit, hHS-M, increases the Ca-sensitivity of muscle contraction. The aim of this study was to investigate the function of hHS-Min vivo and the causative role of abnormal Casensitivity in cardiomyopathy.

The correct management of acute heart failure continues to pose diagnostic and therapeutic challenges. In particular, administering the right type and dose of fluids and drugs, thus avoiding fluid overload while establishing organ perfusion, is of key importance in stabilizing critical patients and improving prognosis. A correct estimate of the fluid volume status, however, may be difficult, as the invasive evaluation of cardiac filling pressures by cardiac catheterization is limited in routine medical practice, and there is no universal consensus on the best tools for its non-invasive evaluation.

The latest guidelines of the European Society of Cardiology have proposed a classification of heart failure based on left ventricular ejection fraction. Three distinct groups have been identified: heart failure with ejection fraction ≥50%, between 40 and 49%, and <40%. This classification has the advantage to be simple but it has been criticized because it is not clear whether the mid-range ejection fraction group is an independent category or just a transition phase between the other two groups.

Inappropriate tests are responsible for longer waiting lists, higher economical costs for the National Health System and major clinical risks due to radiation exposure from prescription abuse of diagnostic testing. Clinical inappropriateness frequently derives from poor knowledge of guidelines, "defensive medicine" approach and/or repeat requests of patients and family members. About one third of non-invasive imaging tests are considered inappropriate.

Obesity is a chronic disease and a risk factor for heart failure. In end-stage heart failure, heart transplantation may be the only available treatment option, but obesity is a contraindication for this treatment because of its unfavourable prognosis. Bariatric surgery and its subsequent weight loss may affect the indication for transplantation in patients with heart failure and morbid obesity.

Acute decompensated heart failure (ADHF) is a common reason for admission to the hospital, and readmission is frequent. Multiple factors contribute to rehospitalizations, but inadequate assessment of volume status leading to persistent congestion is an important factor. We sought to determine if focused cardiac ultrasound (FCU) of the inferior vena cava (IVC), as a surrogate of volume status, would predict readmission of ADHF patients after index hospitalization.

Home telemonitoring is becoming more important to home medical care for patients with heart failure. Since there are no data on home telemonitoring for Japanese patients with heart failure, we investigated its effect on cardiovascular outcomes. The HOMES-HF study was the first multicenter, open-label, randomized, controlled trial (RCT) to elucidate the effectiveness of home telemonitoring of physiological data, such as body weight, blood pressure, and pulse rate, for Japanese patients with heart failure (UMIN Clinical Trials Registry 000006839).

Extracorporeal membrane oxygenation (ECMO) has been used increasingly for both respiratory and cardiac failure in adult patients. Indications for ECMO use in cardiac failure include severe refractory cardiogenic shock, refractory ventricular arrhythmia, active cardiopulmonary resuscitation for cardiac arrest, and acute or decompensated right heart failure. Evidence is emerging to guide the use of this therapy for some of these indications, but there remains a need for additional evidence to guide best practices.

Sacubitril, a neprilysin inhibitor in the combination molecule sacubitril/valsartan, slows down degradation of endogenous natriuretic peptides, thereby enhancing their beneficial cardiovascular effects. However, sacubitril might also promote neuronal dysfunction and cognitive impairment in patients with chronic heart failure (CHF) treated with sacubitril/valsartan, due to possible neprilysin inhibition at the level of Central Nervous System.
A retrospective cohort study was undertaken to detect the effects exerted by sacubitril/valsartan on cognitive function in CHF patients.
