Objective: To evaluate cardiovascular autonomic neuropathy (CAN) in type 1 Diabetics and to detect its relation to coronary artery calcification.

Patients and methods: It is a cross sectional study included 62 diabetics and 30 controls. Clinical, laboratory assessment and 24 h holter were done for all patients and controls and coronary artery calcium (CAC) scoring by multisclice CT was done for all patients only. t-test, Mann–Whitney U-test and stepwise multiple regression were used for statistical analyses.

Results: CAC score was positive in 8.1% of patients. Heart rate variability (HRV) was significantly lower in diabetics. All parameters of HRV were insignificantly lower in diabetics with positive CAC score. Patients with microalbuminuria had a significantly lower HRV. HRV had a significant correlation with age of patients, duration of disease, HbA1, and Qtc in diabetics.

Conclusion: Percentage of arrhythmia and early atherosclerosis is high in adolescent type 1 diabetic patients. CAN is associated with early atherosclerosis. Cardiac autonomic neuropathy is associated with older age, longer duration, and poor glycemic control and microalbuminuria.
