Anaemia and iron deficiency (ID) are common and of prognostic importance in heart failure (HF). In both conditions the epidemiology, diagnosis and therapies have been extensively studied in high-income countries but are still largely unexplored in sub-Saharan Africa (SSA). The lack of adequate and robust epidemiological data in SSA makes it difficult to recognise the significance of anaemia and ID in HF. From a clinical perspective, less attention is paid by clinicians to screening for anaemia in HF, and as far as interventions are concerned, there are no clinical trials in SSA that provide guidance on the appropriate interventional approach...

In heartworm disease, several biomarkers of cardiopulmonary injury and inflammatory activity have been studied during the recent years. D-dimer is a fibrin degradation product present after a clot is degraded, which has been reported to provide support for the diagnosis of pulmonary thromboembolism in heartworm disease. Furthermore, concentrations increment with increased disease severity and during the adulticide treatment. This increase in concentration has proved to be valuable. Cardiac biomarkers troponin I, myoglobin and NT-proBNP demonstrated presence of myocardial injury and heart failure, especially in chronic infections, which in some cases, slightly improve after the adulticide treatment...

BACKGROUND: Blockade of the renin-angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC. METHODS: Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled...

BACKGROUND: Effective management of cardiovascular and chronic kidney disease risk factors offers longer, healthier lives and savings in health care. We examined risk factor management in participants of the SCReening Evaluation of the Evolution of New Heart Failure (SCREEN-HF) study, a self-selected population at increased cardiovascular disease risk recruited from members of a health insurance fund in Melbourne and Shepparton, Australia. METHODS: Inclusion criteria were age ≥60 years with one or more of self-reported ischaemic or other heart disease, irregular or rapid heart rhythm, cerebrovascular disease, renal impairment, or treatment for hypertension or diabetes for ≥2 years...

BACKGROUND: Tolvaptan increases free water clearance (aquaresis) and thereby improves hyponatremia. Although hyponatremia on admission is common in patients with congestive heart failure (CHF), little is known regarding the response to tolvaptan in those who also have chronic kidney disease (CKD) with or without hyponatremia. The aim of this subanalysis was to investigate the differences in treatment response between normo- and hyponatremia patients with CHF and CKD stages G3b-5. METHODS: The Kanagawa Aquaresis Investigators Trial of Tolvaptan on HF Patients with Renal Impairment (K-STAR) was a multicenter, open-label, randomized, controlled prospective clinical trial that included 81 Japanese patients with CHF and residual signs of congestion despite oral furosemide treatment (≥40 mg/day)...

INTRODUCTION: Hyperkalemia is a common complication in patients with heart failure or chronic kidney disease, particularly those who are taking inhibitors of the renin-angiotensin-aldosterone system. RDX7675, the calcium salt of a reengineered polystyrene sulfonate-based resin, is a potassium binder that is being investigated as a novel treatment for hyperkalemia. This study evaluated the pharmacodynamic effects of RDX7675 in mice, compared to 2 current treatments, sodium polystyrene sulfonate (SPS) and patiromer...

Fixed combinations of two or three drugs are being frequently used in cardiovascular diseases. This approach markedly increases adherence of the patients to prolonged therapy and thus leads to better control of the diseases. Fixed combinations are often used in hypertension and coronary artery disease (CAD). Cosyrel is the first fixed combination of betablocker (bisoprolol fumarat) and ACE inhibitor (perindopril arginin) available in czech market. The advantage is availability in several concentrations (10 mg/10 mg, 10 mg/5 mg a 5 mg/10 mg a 5 mg/5 mg) , when first indicates bisoprolol dose and the second perindopril...

Hepatocellular carcinoma (HCC) is the second leading cause of death by cancer worldwide. Resection and liver transplantation are the gold standards, but only a minority of people are eligible. Percutaneous ablation therapies, such as microwave ablation (MWA), have consequently been developed. There is a lack of guidelines regarding the treatment of HCCs in end-stage renal disease (ESRD) patients. Here, we report the case of a 67-year-old patient who was undergoing peritoneal dialysis (PD) for chronic congestive heart failure and who presented with an HCC while undergoing PD...

PURPOSE OF REVIEW: Increasing numbers of geriatric patients will present for thoracic surgery as the population ages. The changes in physiologic reserve as well as the increase in comorbid conditions among this population must be considered in order to optimize patient care in the perioperative period. RECENT FINDINGS: For elderly patients with cancer, the risk-benefit relationship for thoracic surgery remains favorable. Consideration of comorbidities, especially chronic obstructive pulmonary disease and congestive heart failure, is important in the setting of surgical treatment, as they have implications for perioperative care as well as postoperative morbidity and mortality...

The prevalence of the right heart failure (RHF) is poorly known. However, RHF is often a consequence of left heart failure due to an interdependance between both ventricles. RHF should be indentified because of prognostic relevance. RHF is defined by the inability to maintain adequate cardiac output through the lung circulation. It can result from volume overload, pressure overload, or a disorder of systolic function. Adaptive mechanisms such as dilation or hyper-trophy will maintain adequate hemodynamics. Once these mechanisms become insufficient, congestive signs and hemodynamic consequences will appear...

The purpose of the present study was to evaluate the cardioprotective effect of ulinastatin against isoproterenol‑induced chronic heart failure (CHF). Compared with the control group, treatment with ulinastatin decreased interventricular septal thickness and left ventricular posterior wall thickness, and improved the left ventricular ejection fraction, left ventricular fractional shortening and peak E and peak A ratio in the isoproterenol‑induced CHF rat. In addition, ulinastatin suppressed inflammation, oxidative stress and apoptosis in heart tissue from isoproterenol‑induced CHF rats...

Cardiac transplantation remains the gold standard in the treatment of advanced heart failure. With advances in immunosuppression, long-term outcomes continue to improve despite older and higher risk recipients. The median survival of the adult after heart transplantation is currently 10.7 years. While early graft failure and multiorgan system dysfunction are the most important causes of early mortality, malignancy, rejection, infection, and cardiac allograft vasculopathy contribute to late mortality. Chronic renal dysfunction is common after heart transplantation and occurs in up to 68% of patients by year 10, with 6...

Central sleep apnea (CSA) and Hunter-Cheyne-Stokes breathing (HCSB) are caused by failure of the pontomedullary pacemaker generating breathing rhythm. CSA/HCSB may complicate several disorders causing recurrent arousals and desaturations. Common causes of CSA in adults are congestive heart failure, stroke, and chronic use of opioids; opioids have hypoventilatory effects. Diagnosis and treatment of hyperventilatory CSA may improve quality of life, and, when associated with heart failure or cerebrovascular disease, reduce morbidity and perhaps mortality...

Caffeoylxanthiazonoside (CYT) is an active constituent isolated from the fruit of the Xanthium strumarium L plant. The aim of the present study was to investigate the cardioprotective effects of oral administration of CYT on chronic heart failure (CHF) and its underlying mechanisms. A rat model of CHF was first established, and cardiac function indices, including the heart/body weight index, left heart/body weight index, fractional shortening (FS), ejection fraction (EF), cardiac output (CO) and heart rate (HR), were subsequently determined by cardiac ultrasound...

Chronic congestive heart failure (CHF) is the end outcome of organic heart diseases and one of the major diseases harmful to human health. Renal sympathetic denervation (RSD) is the anatomical basis of transcatheter renal sympathetic nerve ablation within the renal artery. To date, the roles of norepinephrine and angiotensin II (Ang II) in myocardial apoptosis and their underlying mechanisms have not been well explored. The aim of the present study was to verify the hypothesis that RSD is likely to inhibit myocardial apoptosis by inhibiting the release of norepinephrine and Ang II...

In their clinical practice, physicians can face heart diseases (chronic or acute heart failure) affecting the liver and liver diseases affecting the heart. Systemic diseases can also affect both heart and liver. Therefore, it is crucial in clinical practice to identify complex interactions between heart and liver, in order to provide the best treatment for both. In this review, we sought to summarize principal evidence explaining the mechanisms and supporting the existence of this complicate cross-talk between heart and liver...

BACKGROUND: Chronic heart failure (CHF) is associated with skeletal muscle abnormalities contributing to exercise intolerance, muscle loss, and negative impact on patient prognosis. A primary role has been proposed for mitochondrial dysfunction, which may be induced by systemic and tissue inflammation and further contribute to low insulin signalling. The acylated form of the gastric hormone ghrelin (AG) may improve mitochondrial oxidative capacity and insulin signalling in both healthy and diseased rodent models...

. INTRODUCTION: The association of hepatitis C virus (HCV), cryoglobulinemia, and membranoproliferative glomerulonephritis (MPGN) is well known. Treatment of underlying HCV infection has greatly improved in recent years with the introduction of direct-acting antivirals (DAA), which have demonstrated curative sustained viral response (SVR) rates for select viral genotypes with the added benefit of less drug side effects. However, a mainstay of newer DAAs is sofosbuvir, which is contraindicated in patients with severe renal impairment...
