Summary

In order to further clarify the interaction of PPIs with clopidogrel anti - platelet effect , the investigators designed a clinical randomized controlled trials of omeprazole and pantoprazole antiplatelet effect of clopidogrel .In this experiment , the investigators have taken a randomized NSTE-ACS hospitalized patients met the inclusion criteria were randomly divided into omeprazole and pantoprazole groups . On the day of admission , all patients taking clopidogrel loading dose 300mg + aspirin 300mg and the subsequent maintenance dose of clopidogrel 75mg + aspirin 300mg and omeprazole group taking omeprazole 20mg / d , pantoprazole group taking pantoprazole 20mg / d. Respectively, on the day of admission ( before medication ) , medication for 12-24 hours , medication after 72 hours , 30 days , each taken early morning fasting venous blood again , measuring AA 、ADP - induced platelet aggregation . And selected 30 days , 6 months and 12 months to record the patient's clinical adverse events ( including death , myocardial infarction , and any revascularization , stent thrombosis , recurrent angina , rehospitalization due to cardiovascular disease , bleeding events) . To assess the impact of PPIs on clopidogrel antiplatelet effect by observing 1 year follow-up results , and further explore the optimal combination of dual anti-platelet and joint PPIs course of treatment , appropriate dosage and the best time to provide reasonable for clinical programs to create a personalized treatment system , improve the patient's quality of life .
