Abstract:
Objective To investigate the relationship between the plasma levels of ET-1,TAT,and hs-CRP and slow coronary flow syndrome (SCFS),and explore effects of coronary endothelial function,coagulation function,and inflammatory reaction on blood flow of coronary artery.Methods A total of 400 cases with normal blood flow of coronary artery by coronary angiogram was randomly selected.The coronary flow patterns were determined by corrected thrombolysis in myocardial infarction frame count method (cT-FC).Among them,45 cases whose average cTFC more than 27 were assigned as SCFS group,the other 45 cases no SCFS.Plasma levels of ET-1,TAT and hs-CRPwere examined with enzyme-linked immunosorbent assay (ELISA),and were compared between two groups.Moreover,multivariate analysis evaluating predictors of SCFS was performed with regression test.Results No statistical difference was found between two groups concerning the gender,history of hypertension,diabetes mellitus,and cigarette alcohol percentage..The plasma level of HDL in SCFS group was lower than that of no SCFS [(1.22 ± 0.42) mmol/L vs (1.44±0.34) mmol/L,t =-2.731,P ＜0.01],but the plasma level of glucose in the former was higher than that of the latter [(5.68 ±0.62) mmol/L vs (5.10 ±0.84) mmol/L,t =3.727,P ＜0.01].However,Plasma levels of ET-1,TAT and hs-CRP in SCFS were higher than that of no SCFS [(94.3 ± 16.78) ng/Lvs (83.5±12.53) ng/L,t =3.051,P ＜0.01;(12.96±3.24)μg/Lvs (8.76 ±2.64)μg/L,t =5.945,P ＜ 0.01 ; (2.48 ± 0.35) μg/L vs (1.38 ± 0.46) μg/L,t =11.259,P ＜ 0.01].Furthermore,Logistic regression analysis showed that ET-1,TAT and hs-CRP were risk factors for SCFS (OR ＞ 1.22).Conclusions Due to coronary endothelial dysfunction,endothelial inflammatory reaction,and activated coagulation function,slow coronary flow of coronary artery occurs.
