Atherosclerosis is characterised by intimal lesion called atheroma that impinge on the vascular lumen and can rupture leading to sudden occlusion. Carotid intimal media thickness is used as a surrogate marker of atherosclerosis. Thus, the aim of the study was to estimate the prevalence of atherosclerotic cardiovascular disease in newly diagnosed diabetics using carotid intimal media thickness. The study was conducted on 50 patients. The result showed that the mean age of the patients was 52.3+ 8.36 years, with majority of the patients belongs to age group of >50 years of age followed by 41-50 years of age. Majority of the patients were females, but higher prevalence of atherosclerosis was observed in males (95%) compared to females (71%) who were diabetics. Patients with other comorbities like HTN has higher prevalence of atherosclerosis. It was observed that patients with risk factors like smoking, alcohol had higher prevalence of atherosclerosis. Diabetes complications and uncontrolled glycemic control also correlates the with atherosclerosis. Dyslipidemia also positively correlates with atherosclerosis prevalence (p<0.05). Overall, these findings highlight the potential utility of CIMT in the detection of subclinical atherosclerosis and a useful tool helping to guide treatment decision for preventing clinical events.
