effect of alpha lipoic acid on cardiac autonomic function and platelet reactivity in type I diabetes

This study is testing whether a supplement called alpha lipoic acid — a natural antioxidant — can improve heart nerve function and reduce abnormal platelet activity (clotting cells) in people with type 1 diabetes. Diabetes can damage nerves over time, including those that control the heart. Alpha lipoic acid may protect against this damage. Participants will receive either the supplement or a placebo (inactive pill) to compare results. You may be eligible if: - You have type 1 diabetes - You are between 18 and 85 years old You may NOT be eligible if: - You have had a heart attack or have cardiac ischemia (reduced blood flow to the heart) - You have an active inflammatory disease - You have a blood cancer or other blood disorder Talk to your doctor about whether this trial might be right for you.
