[Value of ceramide in the diagnosis and risk prediction of coronary artery disease].

Objective: To evaluate the clinical values of 4 types of ceramides (Cer1, Cer2, Cer3, Cer4) in the coronary artery stenosis, clinical diagnosis and risk prediction. Methods: A total of 890 patients with coronary heart disease (CHD) in Beijing Anzhen Hospital between March 2018 and August 2018 were enrolled. The relationships between different degrees of coronary artery stenosis and ceramide levels was investigated. Diagnostic value of ceramides on acute myocardial infarction was analyzed. Meanwhile, Major adverse cardiac and cerebrovascular events (MACCE) in 1 year after discharging were collected to evaluate the predictive value of ceramides on risk of CHD and stroke. Results: This study showed that there were no significant differences of ceramide levels in CHD patients with different degrees of coronary artery stenosis (P>0.05), and the area under receiver operating characteristic (ROC) curve in the diagnosis of acute myocardial infarction patients was 0.725. Conclusions: Ceramide is proved to be helpful in the diagnosis of acute myocardial infarction and MACCE prediction. The relationships between ceramide and degrees of coronary artery stenosis as well as the prognosis of CHD need further elucidation.
