Taking all subjects into 3 groups, patients with ICM tended to have higher IL-34 levels compared to both patients with CAD and normal cardiac function, and to control subjects without CAD (122.52 ± 115.30 vs. 95.02 ± 101.43 vs. 82.57 ± 84.24 pg/ml, respectively; P < 0.001) (Figure 1B). The gene discussed is IL34; the disease is coronary artery disorder.
