Abstract:
Objective To investigate the correlation ofchemokine CX3CL1 and the major adverse cardiovascular events (MACCE) within 1 year in patients with ST elevation myocardial infarction (STEMI).Methods Five hundred patients with STEMI were continuously selected from the Department of Emergency,General Hospital of Shenyang Command,and 5ml venous blood was extracted at the time of admission.Plasma CX3CL1 levels were detected by ELISA.The median of CX3CL1 plasma concentration of all selected patients (2108.3pg/ml) was used to assign the patients to low expression group (＜2108.3pg/ml) and high expression group (≥ 2108.3pg/ml).The baseline information and the medical history of patients were recorded and followed up by telephone inquiry for 1 year.The endpoint events were defined as MACCE (including cardiac death,heart failure,nonfatal stroke and nonfatal myocardial infarction).Based on the MACCE in 1 year following up,patients were assigned into MACCE group and non-MACCE group.Multivariable Cox regression analysis was performed to analyze the correlation between CX3CL1 level and MACCE in STEMI patients.Results The plasma CX3CL1 level significantly increased in MACCE group compared with that in Non-MACCE group,the difference was statistically significant (P＜0.01).Kaplan-Meier and Cox regression analysis showed that the plasma concentration of CX3CL1 was independently associated with the occurrence of MACCE within 1 year (HR=1.124,95％CI:1.032-1.217,P=0.003).Conclusion Chemokine CX3CL1 concentration in plasma is positively correlated with the prognosis of patients with STEMI,and can be used in the prognosis assessment of STEMI patients.
