BACKGROUND: Previous studies have shown low hemoglobin (Hb) to have an adverse effect on survival in patients with congestive heart failure (CHF) and reduced left ventricular (LV) ejection fraction (EF); but its effect on survival in patients with CHF and normal EF is not known. HYPOTHESIS: This study sought to ...

Candesartan is a long-acting angiotensin receptor antagonist that is well absorbed from the gastrointestinal tract, with insurmountable receptor binding abilities. Recent studies have shown candesartan to be an effective therapy for heart failure patients, producing a significant reduction in mortality and morbidity. Importantly, studies have demonstrated that candesartan is effective ...

There are limited systematic data on the incidence, clinical characteristics and outcomes of congestive heart failure (CHF) in patients with hyperthyroidism. The aim of this study was to investigate the incidence, clinical characteristics and outcome of CHF as the initial presentation in patients with primary hyperthyroidism. The prevalence, clinical characteristics ...

Two ways to evaluate the symptoms of heart failure are the New York Heart Association (NYHA) classification and asking patients how far they can walk (walk distance). The NYHA system is commonly used, although it is not clear how individual clinicians apply it. To investigate how useful these measures are ...

OBJECTIVE: We previously noted secondary hyperparathyroidism (SHPT) in African-American patients hospitalized during February, 2005 with either untreated or treated congestive heart failure (CHF) due to ischemic or idiopathic cardiomyopathy. Herein, we hypothesized that housebound African-American patients hospitalized during the period of June 1 through August 31, 2005, with CHF would ...

Autoantibodies specific for the beta(1)-adrenoceptor (beta(1)-AR) have been implicated in the pathology of congestive heart failure (CHF). We hypothesized that the presence of autoantibodies against beta(1)-AR (anti-beta(1)-AR) is associated with left ventricular (LV) remodelling in response to metoprolol. Synthetic beta(1)-AR peptides served as the target antigen in an ELISA (enzyme-linked ...

OBJECTIVE: Pulmonary arterial hypertension related to scleroderma (PAH-Scl) is associated with high morbidity and mortality as well as poorer response to therapy and worse outcomes compared with the idiopathic form of PAH (IPAH). Scleroderma is an autoimmune disease that can affect left and right heart function directly through inflammation and ...

BACKGROUND: The mechanisms underlying high-frequency QRS components (HF-QRS) are incompletely understood. One theory is that HF-QRS are related to the conduction velocity of the heart. The purpose was to test this hypothesis by comparing HF-QRS in patients with left or right bundle branch block (LBBB and RBBB, respectively) to those ...

Evidence exists for race-specific differences in the cause and natural history of heart failure (HF). These differences may have important treatment implications, but relatively limited data on African-Americans exist. A cohort of 89 African-American patients admitted to an urban teaching hospital with diagnoses of HF was examined. Most patients had ...

An Internet-based store-and-retrieval telemedicine system to communicate between patients and their healthcare provider was tested. The system requires no specialized equipment, is Web-based, and allows frequent surveillance of the health status of the patients with heart failure (HF). Thirty six patients were recruited to evaluate a Web-based telemedicine system for ...

Patients with tachyarrythmias as a result of thyroid storm have been typically treated with beta-blockers to decrease the heart rate and alleviate beta-receptor mediated symptoms such as anxiety and tremulousness. We report an unusual case of a previously well young man presenting to the emergency department with atrial flutter and ...

OBJECTIVE: The Thr164Ile-beta(2)-adrenoceptor (AR) polymorphism exhibits lower affinities for catecholamines and reduced basal and agonist-stimulated adenylyl cyclase activity in vitro. It has been suggested that patients with chronic heart failure (CHF) due to ischemic or dilated cardiomyopathy carrying the Thr164Ile-beta(2)AR polymorphism exhibit much more rapid progression to death or heart ...

Previous research (J. C. Coyne et al., 2001) that showed that marital functioning predicted mortality among patients with chronic heart failure (CHF) led to an examination of whether expressed emotion (EE) captured negative marital influences on patient survival. The authors assessed EE using 5-min speech samples obtained from patients (137 ...

Non-potassium-sparing diuretics are commonly used in heart failure (HF). They activate the neurohormonal system, and are potentially harmful. Yet, the long-term effects of chronic diuretic use in HF are largely unknown. We retrospectively analysed the Digitalis Investigation Group (DIG) data to determine the effects of diuretics on HF outcomes. Propensity ...

OBJECTIVES: Congestive heart failure (CHF) is the major cause of death and hospitalization in the elderly population. Simple markers that can be measured anywhere at low cost are necessary to identify patients at high risk. Recent studies have reported that hyperuricemia is a prognostic marker for CHF. However, it is ...

BACKGROUND: Statins may be of potential benefit in patients with congestive heart failure (CHF) due to modulation of neurohormones and their antioxidant, antiinflammatory, and antifibrotic properties. To test this hypothesis, we performed a case-control study by using a prospective registry of patients admitted to our hospital for CHF. METHODS AND ...

BACKGROUND: Aldosterone antagonists reduce morbidity and mortality in patients with severe heart failure, but the mechanisms responsible are not fully understood. Observations in animal models suggest that elevated levels of aldosterone promote oxidative stress and inflammation in the myocardium. It is unknown if these findings are relevant to heart failure ...

Many patients with congestive heart failure develop neurologic dysfunction. This may take the form of a cardiac encephalopathy that shares clinical features with other metabolic encephalopathies. The causes are multiple. There is a particular, previously unreported, syndrome that occasionally develops in some patients with congestive heart failure that resembles the ...
