Abstract
We enrolled 20 patients with type 2 diabetes mellitus without clinical evidence of cardiovascular disease, malignancy, chronic inflammatory disorders, intercurrent illness, renal or hepatic insufficiency or contraindications to clopidogrel who had not taken antiplatelet agents within the preceding two weeks. Ethical approval was obtained from the local ethics committee and all participants provided written informed consent. They were treated with clopidogrel 75 mg daily for 28 days. Fasting peripheral venous blood samples were obtained at baseline and at 28 days.
