About
For acute coronary syndrome patients undergoing cardiac catheterization after stenting, we will give dual antiplatelet drugs (dual antiplatelet agents) therapy, the choice of the basis of medical criteria (clinical guidelines) routine as aspirin + clopidogrel or aspirin + ticagrelor, according to medical guidelines currently no other disposal alternative proposal (unless adverse drug tolerance or bleeding can not be administered); idea of this experiment for acute coronary syndrome or conventional cardiac catheterization after stenting, platelet miRNA expression (miR-96 , miR-200b, miR-495, miR-107) after cardiac catheterization and interventional treatment of clopidogrel or ticagrelor acceptance of platelet reactivity (PRU) correlation values (given clopidogrel or ticagrelor determined by the clinician, the patient follow-up experiment to track only and observation), aims to explore under different platelet reactivity (hyper-reactive or hypo-reactive), their differences in miRNA performance.
