Chronic kidney disease and chronic heart failure are closely interlinked; an abnormality in one system adversely impacts upon the function of the other. Despite the wealth of evidence available for beneficial treatment strategies in chronic heart failure, the prognosis remains poor and optimum therapy under-utilised. The applicability of proven therapies ...

BACKGROUND: This pilot study examined the feasibility of monitoring changes in body weight and body-fat percentage (BF%) using commercially available digital weight scale incorporating bioelectrical impedance analyzer (HBF-352-W, Omron Healthcare Co, Kyoto, Japan) to estimate changes in body fluid status in definite heart failure (HF) patients during follow-up. METHODS AND ...

OBJECTIVE: The 1985 International Extracranial-Intracranial (EC-IC) Bypass Trial failed to show a benefit following surgery in patients with varying degrees of angiographic ICA stenosis. More recent studies using modern technology to identify appropriate candidates, however, have generated promising findings. As a result, controversy exists regarding the role of this technique ...

Nocturnal breathing disorders in the form of periodic breathing (PB) are very common in heart failure (HF) patients. There is an increasing interest in simple and affordable tools to screen patients and monitor these disorders at home on a long-term basis. We aimed to assess the pathophysiological and clinical relevance ...

Chronic congestive heart failure (CHF) is associated with an increase in cytokines and inflammatory markers, particularly in elderly patients in whom chronic inflammation is generally present per se. In the present pilot study, neutrophil gelatinase-associated lipocalin (NGAL), a recently discovered cytokine, was analyzed together with different clinical and laboratory parameters ...

Anemia is common in heart failure patients but its prevalence varies widely according to various sources. There is no agreement regarding the definition of anemia to be used and several risk factors have been found to be associated with higher prevalence of anemia in heart failure patients. The prevalence of ...

We assessed the hypothesis that non-invasive measurement of stroke volume index can replace invasive measurements in patients with chronic heart failure. Non-invasive impedance cardiography (ICG) measurements together with invasive hemodynamic thermodilution (TD) measurements were performed in 13 patients with severe chronic heart failure (NYHA III-IV). Agreement between ICG and TD ...

BACKGROUND: Patients with severe congestive heart failure (CHF) often have unexplained elevations in serum concentrations of troponin T (TnT), and it is proposed that this is due to cardiac TnT release because of underlying cardiac disease. We investigated whether impaired renal function is an additional underlying phenomenon contributing to increased ...

Sepsis is a potentially lethal condition, and is one of the major causes of death in non-coronary intensive care units. Sepsis syndrome progresses through a number of increasingly severe stages, from systemic inflammatory response syndrome (SIRS) through sepsis, severe sepsis and septic shock. Each stage of sepsis is potentially characterized ...

sorafenib, a tyrosine-kinase inhibitor, is widely used in the treatment of advanced hepatocellular carcinoma. Drug-related toxicities are generally mild but sorafenib, as other similar agents, may induce elevation of systemic arterial blood pressure levels in relation to an interaction with cardiovascular system probably mediated by HIF pathway. This side effect ...

Patients with chronic heart failure (CHF) with periodic breathing (PB) and Cheyne-Stokes respiration (CSR) tend to exhibit higher mortality and poor prognosis. This study proposes the characterization of respiratory patterns in CHF patients and healthy subjects using the envelope of the respiratory flow signal, and autoregressive (AR) time-frequency analysis. In ...

Overproduction of pro-inflammatory cytokines is a well established factor in the progression of chronic heart failure (CHF). Changes in cellular immunity have not been widely studied, and the impact of standard medication is uncertain. Here we investigate whether a leukocyte redistribution occurs in CHF and whether this effect is influenced ...

BACKGROUND: Amiodarone (AMD) is a strong antiarrhythmic drug but has severe side effects such as pulmonary toxicity. There are no indicators or drugs that can prevent the development of amiodarone-induced pulmonary toxicity (AIPT). METHODS: We collected data for 96 consecutive patients treated with AMD and analyzed clinical factors related to ...

In patients with congestive heart failure (CHF) cachexia as well as Cheyne-Stokes respiration (CSR) are well known disorders. The relationship between CSR and cardiac cachexia however, remains unclear so far. Clinical as well as full-night polysomnographic data from 12 cachectic patients were compared to 13 non-cachectic patients with CHF. The ...

Hypereosinophilic syndromes (HES) constitute a rare and heterogeneous group of disorders, defined as persistent and marked blood eosinophilia associated with evidence of eosinophil-induced organ damage. Cardiac dysfunction is the most frequent result of end-organ damage and is the major cause of morbidity and mortality among patients with HES. Despite patients ...

Extracardiac or genetic abnormalities (EGA) represent a factor in the morbidity of patients with congenital heart disease. We evaluated the way neonates with CHD are screened at our institution and determined the yield for the screening tests. We reviewed the charts of 223 neonates with structural CHD. Subjects were categorized ...

Major characteristics of symptomatic patients with heart failure are exercise intolerance, poor prognosis, and poor quality of life (QOL). However, most QOL questionnaires are applicable for patients with mild to moderate heart failure, and are not sufficiently sensitive to discriminate between patients with NYHA classes III and IV. Therefore, it ...

Beta blockers have a proven benefit in the management of patients with acute coronary syndromes (ACS) and for secondary prevention of coronary events. Current guidelines list such reactive airway diseases (RADs) such as asthma and chronic obstructive pulmonary disease as relative contraindications to beta-blocker use. However, the co-morbid burden of ...

Optimal care of patients with heart failure requires a multifaceted approach that includes guideline-driven, evidence-based therapies, intensive patient education, careful initial and follow-up assessment, and appropriately constructed nutrition prescriptions. Central to the construct of the nutrition prescription is advice regarding sodium consumption. It is intuitively and generally agreed upon that ...

Hyponatremia is the most common electrolyte abnormality found in hospitalized patients with heart failure. It may occur in patients who have hypovolemic, hypervolemic, or euvolemic state. It is usually not corrected by available therapies. It is a major predictor of prognosis, and correction of hyponatremia can be effectively accomplished by ...
Negrão Carlos E - - 2009
BACKGROUND: The progression of heart failure in Chagas' disease has been explained by remodeling, leading to neurohumoral activation, or by the direct parasite damage to parasympathetic neurons during acute phase, leading to early sympathetic activation and progressive heart failure. To help distinguish between these hypotheses we studied muscle sympathetic nerve ...

Anemia is a common comorbidity in patients with heart failure and is associated with worse long-term outcomes. Although the cause of anemia in heart failure is unclear, the weight of evidence suggests that renal dysfunction, along with neurohormonal and proinflammatory cytokine activation in heart failure, favors the development of anemia ...

BACKGROUND: Activation of inducible nitric oxide synthase (iNOS) has been reported in congestive heart failure (CHF) conditions. However, it is unknown whether activation of iNOS affects prognosis of CHF patients. We prospectively studied the influence of activation of iNOS in the forearm on the outcome of CHF patients. METHODS AND ...
