Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The focus of this project is cardiovascular diabetic autonomic neuropathy (DAN). DAN affects the nerves that control heart rate and blood flow to the heart in people with diabetes. DAN may cause problems with the rhythm of the heartbeat or decrease blood flow to the heart. Three medications will be tested for their effectiveness in DAN.
