BACKGROUND: Adiponectin, which is a collagen-like plasma protein produced by adipose tissue, has in general anti-atherogenic and anti-inflammatory effects. Recently it was shown to be elevated in chronic heart failure patients. However whether this holds true in the elderly heart failure patients who are often associated with malnutrition remains unknown. ...

BACKGROUND: In the heart elevated levels of TNFalpha can cause lethal heart failure, like Dilated Cardiomyopathy (DCM). The level of TNFalpha production is in part determined by promoter gene polymorphisms. We investigated whether the TNFalpha promoter gene polymorphism is in this way involved in the outcome of end-stage heart failure ...

PURPOSE: Several studies suggest the clinical efficacy of carvedilol in reducing atrial and ventricular arrhythmias in patients with left ventricular dysfunction (LVD) due to congestive heart failure (CHF) or following myocardial infarction. However, the mechanisms supporting its antiarrhythmic efficacy have been derived from experimental studies. In this prospective, placebo-controlled trial ...

BACKGROUND: Plasma levels of adiponectin are decreased in patients with ischemic heart disease, but increased in patients with heart failure (HF). The source of increased adiponectin levels in patients with HF remains unknown. This study examined whether adiponectin, an adipocyte-derived protein with cardioprotective actions, is released from the heart in ...

Imperforate Anus (IA) is an abnormality of the anus and rectum that is present at birth. The infant is born without a normal rectal opening. Anorectal malformations occur in one in 5,000 live births. Anorectal and urogenital malformations are rarely fatal, although some associated anomalies (cardiac, renal) can be life ...

Background In the heart elevated levels of TNFα can cause lethal heart failure, like Dilated Cardiomyopathy (DCM). The level of TNFα production is in part determined by promoter gene polymorphisms. We investigated whether the TNFα promoter gene polymorphism is in this way involved in the outcome of end-stage heart failure ...

Carcinoid heart disease (CHD), reported in 50% to 70% of patients with carcinoid syndrome, is thought to be related to the production of 5-hydroxytryptamine by the tumor. The development of new therapeutic modalities designed to reduce tumor hormone production may have altered the development of CHD. Currently, echocardiography is performed ...

PURPOSE: We have shown previously that reduced integer heart rate variability (HRVi) predicts death in trauma patients. We hypothesized that heart rate multiscale entropy (MSE), a potential measurement of physiologic complexity, would predict death more robustly than HRVi. MATERIALS AND METHODS: Two hundred eighty-five patients had heart rate data meeting ...

INTRODUCTION: Cachexia is common in chronic heart failure (CHF) and may be due to a combination of reduced appetite, and increased metabolic rate due to immune activation. This hypermetabolism, with an increase in acute phase protein turnover, also seen in cancer cachexia, might contribute to weight loss seen in severe ...

BACKGROUND: Cardiac resynchronisation therapy (CRT) improves symptoms and prognosis in patients with heart failure and cardiac dyssynchrony. Guidelines from the National Institute of Health and Clinical Excellence in the United Kingdom recommend CRT for patients with recent or persistent moderate or severe symptoms of heart failure. This analysis investigated whether ...

Compared with earlier models, current pumps are much smaller, simpler, and more efficient, offering long-term or even permanent support. They fit a wider size range of patients and are less invasive to implant. Because they have few moving parts, they are less susceptible to infection and failure. Additionally, they offer ...
