Circulating microRNAs may reflect renal dysfunction and systemic vascular injury. We investigated whether plasma miR-148b-3p is associated with renal function and carotid plaque burden in patients with established CAD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a single-center cross-sectional study of 190 hospitalized patients with coronary artery disease, including 90 with CKD and 100 without CKD. Plasma miR-148b-3p was measured by quantitative polymerase chain reaction. Carotid atherosclerosis was assessed by ultrasonography and quantified by Crouse score. Associations with renal function and plaque burden were evaluated using correlation analysis, multivariable regression, restricted cubic spline analysis, ROC analysis, bootstrap validation, and incremental predictive analyses.

For carotid plaque detection, in exploratory ROC analyses, plasma miR-148b-3p showed limited discrimination in non-CKD patients and moderate discrimination in the CKD subgroup. Although bootstrap resampling suggested internal stability, these estimates require external validation. Integrative analyses identified enrichment of endothelial and atherogenic pathways and highlighted 4 shared candidate genes\u2014MRPS25, ADAMTS5, MMP15, and RAB12.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with established CAD, plasma miR-148b-3p was associated with CKD status, impaired renal function, and carotid plaque burden.
