Our previous studies [6, 17] found that the positive detection rate of moesin antibody in patients with coronary artery occlusion was significantly higher than that in patients with mild coronary artery stenosis (P < 0.01) and the severity of coronary artery lesions increased when the positive rate of Moesin antibody and OD value increased (P < 0.05). Here, MSN is linked to coronary stenosis.
