Autonomic nervous system dysfunction in advanced systolic heart failure.
Summary of "Autonomic nervous system dysfunction in advanced systolic heart failure."
An alteration of the autonomic nervous system has been described in heart failure (HF). The aim of this study was to assess, compare and relate the impairment of both arms of the autonomic nervous systems, the sympathetic and parasympathetic (SNS and PNS) in a same group of patients.

The pathophysiology of heart failure (HF) is characterized by hemodynamic abnormalities that result in neurohormonal activation and autonomic imbalance with increase in sympathetic activity and withdr...
Pathophysiology of heart failure has been considered to be a damaged state of systolic function of the heart followed by a state of low cardiac output that is, systolic heart failure. Even if systolic...
Despite the fact that up to half of all heart failure occurs in patients without evidence of systolic cardiac dysfunction, there are no universally accepted diagnostic markers and no approved therapie...
Right ventricular (RV) dysfunction is associated with poor prognosis in patients with heart failure (HF). Echocardiographic assessment of RV systolic function is challenging. The ability to visualize ...
Amongst patients with heart failure (HF) due to left ventricular systolic dysfunction (LVSD) in sinus rhythm, those with higher resting heart rate (HR) have a worse prognosis. Reducing sinus rate to 5...

Aims: To test the hypothesis that Diastolic dysfunction severity correlates with adverse clinical outcome in patients with systolic heart failure.
The investigators are interested in the role of the autonomic nervous system in the regulation of endothelial function. In particular, the investigators will study how endothelial function...

Medical and Biotech [MESH] Definitions
Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.
The enteric, parasympathetic, and sympathetic nervous systems taken together. Generally speaking, the autonomic nervous system regulates the internal environment during both peaceful activity and physical or emotional stress. Autonomic activity is controlled and integrated by the central nervous system, especially the hypothalamus and the solitary nucleus, which receive information relayed from VISCERAL AFFERENTS; these and related central and sensory structures are sometimes (but not here) considered to be part of the autonomic nervous system itself.
Nerves and plexuses of the autonomic nervous system. The central nervous system structures which regulate the autonomic nervous system are not included.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Conditions associated with damage or dysfunction of the nervous system caused by exposure to heavy metals, which may cause a variety of central, peripheral, or autonomic nervous system injuries.
