Abstract:
Objective To investigate the change of serum CD62p of coronary heart disease (CHD) patients after different doses of clopidogrel administration.Methods One hundred and ninety-one patients with CHD were selected as our subjects.Of which,95 cases were with SAP and 66 cases were with non ST segment elevation acute coronary syndrome (NST-ACS).SAP patients were randomly given clopidogrel at dose of 75 mg/d or 150 mg/d and served as A and B groups.NST-ACS patients were randomly given 300 mg clopidogrel,then randomly divided into C and D groups with sequentially taking clopidogrel at dose of 75 mg/d or 150 mg/d respectively.Thirty healthy peoples were served as E group without drug intervention.Concentrations of serum CD62p were detected by Elisa before taking clopidogrel,24 h and the fifty day of after taking clopidogrel.Results (1) Before taking clopidogrel,the serum concentrations of CD62p in CHD patients were higher (A group:(7.62 ± 2.99) ng/L,B group:(8.48 ± 3.13) ng/L,C group:(9.50 ± 3.32) ng/L,D group:(10.22 ± 5.14) ng/L than that of healthy control group ((5.49 ± 1.99) ng/L,P ＜ 0.05).The Serum CD62p levels in SAP patients were lower than that of NST-ACS patients (P ＜ 0.05).(2)The serum concentrations of CD62p in A and B groups at before taking clopidogrel were (7.62 ±2.99) ng/L and (8.48 ±3.13) ng/L respectively,higher than that four days after taking clopidogrel ((6.79 ± 2.51) ng/L,(6.37 ± 1.80) ng/L;t =2.390,4.520;P ＜0.05 or P ＜0.01).There was no statistical significant difference between A and B groups(P ＞0.05).(3) In C and D groups,the serum CD62p at before taking clopidogrel were (9.50 ±3.32) ng/L and (10.22 ±5.14) ng/L,higher than that after taking clopidogrel for four days ((8.21 ± 2.62) ng/L,(8.17 ± 2.37) ng/L; t =2.084,2.157 ; P ＜ 0.05).No significant difference was seen between C and D groups (P ＞ 0.05).Conclusion The serum CD62p in patients with CHD was higher than that in the healthy control.Clopidogrel administration can decrease serum CD62p in CHD patients.
