Cocoa Flavanols and Painfree Walking Distance

November 12, 2013 updated by: Klinik für Kardiologie, Pneumologie und Angiologie, Heinrich-Heine University, Duesseldorf

Long-term Effect of Dietary Intervention With Flavanol-containing Cocoa on Vascular Function of Diabetic Patients

To characterize potential vascular long-term effects of flavanols in patients with peripheral artery occlusive disease (PAOD), a placebo-controlled double-blinded randomized control study will be performed in 62 patients randomized in two groups. Patients will twice daily receive either a flavanol-poor cocoa drink or a flavanol-rich cocoa drink over a period of 60 days months.

Detailed Description

62 Type 2 diabetics according to the criteria of the American Diabetes Association suffering from PAOD with a pain free walking distance less than 250m will be enrolled.

Patients will twice daily receive either a flavanol-poor cocoa drink (13mg/dl)or a flavanol-rich cocoa drink (596mg/dl) over a period of 60 days.

The general condition, the pain free walking distance and the vascular function measured by Doppler Ultrasound will be determined before and two month after cocoa ingestion
