Overview

Diabetic cardiac autonomic neuropathy (DCAN) is a common chronic complication that reduces survival in patients with diabetes. Epidemiological surveys have shown that the prevalence of DCAN is 25-75% in people with type 2 diabetes. The onset of DCAN is insidious and easy to be ignored in the early stage. With the progression of the disease, the following clinical symptoms gradually appear, including reduced heart rate variability, exercise intolerance, resting tachycardia, orthostatic hypotension, painless myocardial infarction and even sudden death, which seriously endanger the life and health of type 2 diabetes patients. Existing literature has shown that glucagon-like peptide-1 receptor agonist (GLP-1RA) can improve diabetic peripheral neuropathy and diabetic cognitive dysfunction, but there are few studies on improving diabetic autonomic neuropathy. Insulin resistance is an important risk factor for DCAN. Patients with type 2 diabetes are characterized by insulin resistance, and GLP-1RA is recognized as a drug to improve insulin resistance and control blood sugar in patients with diabetes. In this study, GLP-1RA was used to intervene patients with type 2 diabetes, and the changes in blood sugar control and insulin resistance status of patients were followed up. Special attention was paid to the improvement of autonomic neuropathy in diabetic patients.
