There’s also a significant relationship between serum IL-34 levels and the Gensini score evaluated by the results of coronary angiography (r = 0.189, P < 0.001 in all subjects; r = 0.193, P < 0.001 in male; r = 0.245, P < 0.001 in female) with simple linear correlation analysis, which indicated that subjects with higher serum IL-34 levels were more likely have severe coronary artery stenosis, possibly leading to more severe ICM. The gene discussed is IL34; the disease is coronary stenosis.
