Arterial stiffness is increased in type 1 diabetes (T1D), before any clinical complications of the disease are evident. The aim of the present paper was to investigate the association between cardiac autonomic function and arterial stiffness in a cohort of young T1D patients, without history of hypertension and any evidence of macrovascular and/or renal disease. Large artery stiffness was asses...

Background. Diabetic subjects have a high incidence of cardiovascular accidents, with an altered circadian distribution. Abnormalities in the circadian rhythm of autonomic tone may be responsible for this altered temporal onset of cardiovascular disease. Methods and Results. To assess circadian changes of sympathovagal balance in diabetes, we performed 24-hour power spectral analysis of RR inte...

Gall bladder motor function is impaired in some patients with diabetes. It has been suggested that the abnormalities of gall bladder motility are confined to those patients with autonomic neuropathy. Erythromycin, a motilin receptor agonist, causes gall bladder contraction in both normal subjects and patients with gall stones with impaired gall bladder emptying. The effect of erythromycin on ga...

OBJECTIVE This study examined whether the presence of peripheral sensory neuropathy or cardiac autonomic deficits is associated with postocclusive reactive hyperemia (reflective of microvascular function) in the diabetic foot. RESEARCH DESIGN AND METHODS 99 participants with type 2 diabetes were recruited into this cross-sectional study. The presence of peripheral sensory neuropathy was deter...

The aim of this study was to examine the impact of parental type 2 diabetes on the autonomic nervous system and to determine whether autonomic neuropathy is present and associated with changes in 24-h ambulatory blood pressure (AMBP) and urinary albumin excretion rate (UAER) in nondiabetic subjects with parental type 2 diabetes. We examined 223 nondiabetic offspring of type 2 diabetic subjects ...

1. An association has been reported between QT interval abnormalities and cardiovascular autonomic neuropathy in diabetic patients. The QT interval abnormalities reflect local inhomogeneities of ventricular recovery time and may be related to an imbalance in cardiac sympathetic innervation. Sympathetic innervation of the heart can be visualized and quantified by single-photon emission-computed ...

Objectives To assess if there is an association between the development of chronic complications (retinopathy-DR, nephropathy-DN, peripheral neuropathy– PN and cardiac autonomic neuropathy-CAN) in patients with T1D and 1) the mean glycated Haemoglobin during their followup since diabetes onset (mHbA1c); 2) the standard deviation (SD) of HbA1c over this period, 3) the HbA1c in the first 3 yrs. o...

Intraneural hypoxaemia is recognized as a pathogenic mechanism in diabetic neuropathy. A similar pathophysiological process may occur in chronic obstructive pulmonary disease (COPD). Autonomic neuropathy is not recognized in COPD. We compared 96 patients with hypoxaemic COPD to 22 age-matched control subjects to see whether autonomic dysfunction occurs in COPD and whether there was any correlat...
