Abstract:
Objective To observe the level changes and clinical diagnostic value of follicular statin -1 (FSTL1)in the serum of patients with different types of acute coronary syndrome(ACS).Methods Collected the clinical diagnosis of acute coronary syndrome patients 98 cases,which contained ST segment elevation my-ocardial infarction(STEMI)in 34 cases,non ST elevation myocardial infarction(NSTEMI)in 28 cases,unsta-ble angina pectoris(UA)in 36 cases,while the examination resuLts of healthy people as a control group of 20 cases.The Venous blood was collected and the FSTL1 levels of the 4 groups were detected by ELISA.Results The levels of Serum FSTL1 in ACS group was significantly higher than that in normal control group(P<0.05).Serum FSTL1 of the ACS group were significant correlated with Gensini score,cTNT,hs-CRP(related coefficient:0.210,0.236,0.219 separately).The AUC of FSTL1 was 0.910(95% CI:0.832 -0.988),which was lower than cTNT.The best cut-off value of FSTL1 as a biomarker was 5.65 μg/L(specificity:84.2% and sensitivity:77.5%).Moreover the combination of FSTL1,HDL and cTNT exhibited significantly higher AUC=0.945(95% CI:0.909 -0.981)than did other biomarkers alone or pair combinations.Conclusion In pa-tients with acute coronary syndrome,serum FSTL1 levels has a positive correlation with the degree of coro-nary stenosis and inflammation reaction,and has certain value in the diagnosis of acute coronary syndrome.
