Oxidized Low-Density Lipoprotein (Ox-LDL)‎ and Triggering Receptor-Expressed Myeloid Cell (TREM-1)‎ Levels Are Associated with Cardiometabolic Risk in Nonobese, Clinically Healthy, and Young Adults

Abstract EN

Oxidative and inflammatory substances play an important role in the genesis of processes related to cardiometabolic risk.

High levels of oxidized low-density lipoprotein (Ox-LDL) and of triggering receptor-expressed myeloid cells (TREM-1) are associated with cardiovascular and inflammatory diseases.

In this study, we evaluate the association of the plasma concentrations of Ox-LDL and serum levels of circulating TREM-1 (sTREM-1) with the components of cardiometabolic risk (CMR) and other associated risk parameters.

Although the individuals in this study were young, nonobese, and did not have signs, symptoms, and diagnosis of diseases, they already presented components of CMR.

Ox-LDL lipid fraction correlated positively with CMR-related markers: body mass index (BMI), waist circumference (WC), body fat percentage, total cholesterol, LDL-c, VLDL-c, triglycerides, atherogenic cholesterol, and atherogenic index.

Among these parameters, atherogenic cholesterol had a greater predictive effect for Ox-LDL alterations.

Individuals with higher serum concentrations of sTREM-1 presented higher values for BMI, WC, triglycerides, VLDL-c, and atherogenic cholesterol.

WC showed an effect on the association between the sTREM-1’s inflammatory response and the components of CMR.

The association of oxidative and inflammatory markers with anthropometric parameters and atherogenic cholesterol in nonobese, clinically healthy, and young individuals suggests the importance of early evaluation of these markers in order to prevent future cardiac events.
