Coronary artery calcification, carotid intima-media thickness and cardiac dysfunction in young adults with type 2 diabetes mellitus

Cardiovascular diseases (CVD) are the major causes of mortality in patients with type 2 diabetes mellitus (T2DM). There is paucity of information on prevalence of subclinical atherosclerosis and cardiac dysfunction in young adults with T2DM. This study aimed to assess the prevalence of subclinical atherosclerosis and cardiac dysfunction in young adults with T2DM, asymptomatic for CVD. Sixty-two patients with T2DM, age between 30 and 50 years were evaluated for coronary artery calcium (CAC) score, carotid intima-media thickness (CIMT) and flow-mediated dilatation (FMD) at the brachial artery. All were subjected to 2D-color Doppler echocardiography, electrocardiography and testing for serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hsCRP). The results were compared with those in 60 age, sex and BMI-matched healthy controls. Prevalence of a positive CAC score was comparable among subjects with and without T2DM (14.5% vs 11.7%). Patients with T2DM had a significantly higher CIMT (0.54 ± 0.15 vs 0.49 ± 0.10 mm, p = 0.01), left ventricular (LV) mass (170 ± 36 vs 147 ± 23 g, p
