Abstract:

Objective

To explore the relationship between carotid artery abnormalities and blood lipids, pulse pressure index (PPI), and ankle-brachial index (ABI) in newly diagnosed type 2 diabetes mellitus (T2DM) patients.

Methods

A total of 219 newly diagnosed T2DM patients from the Department of Endocrinology of the First Affiliated Hospital of Jinan University from January to December 2023 were selected for carotid artery ultrasound examination, blood sample testing, and other examinations. The correlation between carotid artery lesions and blood lipids, pulse pressure, and ankle-brachial index in newly diagnosed T2DM patients was analyzed.

Results

The age, SBP, PP, PPI, Cys C, HDL-C, and the prevalence of hypertension in the carotid artery abnormal group were significantly higher than those in the carotid artery normal group (P<0.05), while the TG level was lower than that in the carotid artery normal group (P<0.05). Spearman correlation analysis showed that the carotid intima-media thickness (CIMT) in newly diagnosed T2DM patients was positively correlated with age, PPI, HDL-C, onset type, and history of hypertension (P<0.05). Logistic regression analysis showed that HDL-C was an influencing factor for carotid plaque formation in newly diagnosed T2DM patients.

Conclusions

Reduced HDL-C levels are a risk factor for carotid artery lesions in newly diagnosed T2DM patients. Therefore, initiating management of lipid indicators as early as possible is particularly important for this patient population. Young patients, in particular, require stricter monitoring and regulation of their lipid levels.
