Objective: Risk factors for diabetic cardiovascular autonomic neuropathy (CAN) in patients with type 2 diabetes were analyzed to establish a regression model for evaluating the diagnosis of CAN.
Methods: 325 patients with type 2 diabetes were divided into four groups according to the results of four standard function tests. Every patient was required to offer detailed disease history and accept physical examination, serum and urine tests and examinations including ECG, nerve conduction velocity, retinoscope and Doppler of carotid and lower limb arteries.
