Cardiac Autonomic Function Correlates with Arterial Stiffness in the Early Stage of Type 1 Diabetes
نویسندگان
چکیده
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 assessed by measurement of carotid-femoral pulse wave velocity (PWV). Cardiac autonomic function was assessed by the cardiovascular tests proposed by Ewing and Clarke. Patients with a high cardiac autonomic neuropathy score (≥4) had significantly higher PWV than those with a low score (0-1). A negative, heart rate-independent, correlation between PWV and heart rate variation during respiration was observed (r = -0.533, P < 0.001). In multivariable analysis, E/I index was the strongest correlate of PWV (β-coefficient = -0.326, P = 0.002). Cardiac parasympathetic function is a strong predictor of large arterial stiffness, in young T1D patients free of macrovascular and renal complications.

Background: Diabetic neuropathy is an incapacitating disease that afflicts almost 50 percent of patients with diabetes. A late finding in type 1 diabetes, diabetic neuropathy can be an early finding in non insulin-dependent diabetes. Diabetic neuropathies are divided primarily into two groups, sensorimotor and autonomic. Patients may acquire only one type of diabetic neuropathy or may present w...

To focus on early cardiac and vascular autonomic dysfunction that might complicate type 1 diabetes mellitus in children, we planned an observational, cross-sectional study in a population of 93 young patients, under insulin treatment, subdivided in 2 age subgroups (children: 11.5 0.4 years; adolescents: 19.3 0.2 years). Time and frequency domain analysis of RR interval and systolic arterial pre...
