Increased Circulating Erythrocyte-Derived Microparticles in Patients with Acute Coronary Syndromes

Abstract

Objective: This study is to explore the predictive value of erythrocyte-derived microparticles (ErMPs) in patients with acute coronary syndrome (ACS). Materials & methods: Total 305 subjects were enrolled and divided into the control group and ACS group. Flow cytometry was used to detect the ErMPs. The Gensini score was calculated based on the results of the coronary angiography. Results: Compared with that in the control group, the ErMPs concentration in the ACS group increased significantly and the concentration of ErMPs was correlated with the ACS risk. The concentration of ErMPs and the percentage of ErMPs were positively correlated with the Gensini score. Conclusion: ErMPs may be a new biomarker for predicting the ACS risk and the coronary artery disease severity.
