Cardiac sympathetic dysfunction in haemodialysed patients

Cardiac sympathetic dysfunction in haemodialysed patients.

BACKGROUND The aim of this study was to evaluate the cardiac sympathetic nervous system function in haemodialysed(HD), non-diabetic patients by iodine-123 meta-iodo-benzylguanidine(123I-mIBG). MATERIALS AND METHODS Planar scintigraphy of the chest was performed in 36 HD, male patients; 15 minutes and 4 hours post injection of 370 MBq of 123I-mIBG. The semi quantitative analysis of myocardial ...

Diabetic cardiac autonomic dysfunction: parasympathetic versus sympathetic.

BACKGROUND Diabetic cardiac autonomic dysfunction often causes lethal arrhythmia and sudden cardiac death. 123I-Metaiodobenzylguanidine (MIBG) can evaluate cardiac sympathetic dysfunction, and analysis of heart rate variability (HRV) can reflect cardiac parasympathetic activity. We examined whether cardiac parasympathetic dysfunction assessed by HRV may correlate with sympathetic dysfunction as...

CARDIAC ELECTRICAL DYSFUNCTION IN ACUTE BRAIN LESIONS

This study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. Different abnormalities such as: QT -interval, T...

Cardiac sympathetic dysfunction in the prehypertensive spontaneously hypertensive rat.

Recent studies in prehypertensive spontaneously hypertensive rats (SHR) have shown larger calcium transients and reduced norepinephrine transporter (NET) activity in cultured stellate neurons compared with Wistar-Kyoto (WKY) controls, although the functional significance of these results is unknown. We hypothesized that peripheral sympathetic responsiveness in the SHR at 4 wk of age would be ex...
