Abstract

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is closely related to the development of cardiovascular diseases, and the association between Lp-PLA2 and lower extremity arterial disease (LEAD) in type 2 diabetes mellitus (T2DM) is inconsistent among previous studies. Thus, the present study aimed to investigate whether the increase in Lp-PLA2 is related to the occurrence of LEAD in patients with T2DM. A total of 519 patients with T2DM (173 patients with LEAD and 346 patients without LEAD) were enrolled in this study. The demographics, medical history, serum lipids, glycosylated hemoglobin, Lp-PLA2, and ankle-brachial index (ABI) were recorded and analyzed. The diabetes duration, prevalence of female, prevalence of hypertension, and Lp-PLA2 concentration in the LEAD group were significantly higher than those in the non-LEAD group (duration of diabetes: 15 [10-20] vs 8 [2-12] years, prevalence of female: 49.13% vs 38.73%, prevalence of hypertension: 58.38% vs 38.11%, Lp-PLA2: 145 [108-178] vs 125 [107-138] ng/ml, p < 0.05). Lp-PLA2 was negatively correlated with ABI (r = -0.308, p < 0.001). Results of multivariate logistic regression analysis showed that serum Lp-PLA2 was an independent factor for the development of LEAD (odds...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
