The results demonstrated that age, dyslipidemia, atrial fibrillation, triglyceride, MR (grades 2 to 4), mean TLR2+/CD14+ cells, TLR2+/CD14+ cells <25%, TLR4+/CD14+ cells <0.25%, mean MPO+/CD14+cells, MPO+CD14+ cells <20%, sST2 <14,000 (pg/mL), and mean sST2 were significantly predictive of mild CCS. The gene discussed is CD14; the disease is atrial fibrillation.
