CD34 and atherosclerosis: RA patients had lower CD34+ cell counts and higher ROS, TLR3, and IL-1β levels.Positive correlation between inflammation markers (CRP, IL-1β) and arterial stiffness indices (PWV, AIx).Chronic inflammation in RA with biomarkers like hsCRP and Fibrinogen is associated with impaired vascular repair and accelerated atherosclerosis.
