RESUMEN
by lfow cytometry. According to CAG morphology, the plaques included 3 types as Type I, Type II and TypeⅢ. The patients also received coronary CT angiography (CTA), upon CTA value, the plaques were classiifed by soft plaque, ifbrous plaque and calciifed plaque. Expressions of platelet surface EMMPRIN and GPVI among different groups were compared. Results:①Compared with Control group, ACS and SAP groups had increased expressions of EMMPRIN (5.82 ± 0.81 and 3.45 ± 0.48) vs (1.35 ± 0.15) and GPVI (16.22 ± 5.27 and 8.20 ± 2.87) vs (4.14 ±1.17); the expressions in ACS group were higher than those in SAP group, allP Conclusion: Expression levels of platelet surface EMMPRIN and GPVI were closely related to the stability of coronary plaque, both of them were the risk factors for severe coronary lesions. EMMPRIN and GPVI may have certain predictive value for early diagnosis of arteriosclerosis in ACS patients.
