Research Design & Methods: A cross-sectional study of T1DM patients without a history of cardiovascular disease. CAC and VAT are measured using a CT scan. CAC is scored using the Agatston method. Echocardiography is performed to assess contractile abnormalities. Serum levels of adipocytokines (adiponectin, leptin, IL-6 and TNF-a) are measured using ELISA assays.
