Study on the Registration of Coronary Heart Disease Patients Undergoing PCI

Dual antiplatelet therapy, comprising a low-dose aspirin and a kind of P2Y12 Receptor Inhibitors, has been the mainstay of the management in patients with acute coronary syndromes and/or undergoing Percutaneous Coronary Intervention (PCI). While variability to P2Y12 receptor inhibitors is common in patients and is a major cause of adverse cardiovascular events. Low response to P2Y12 receptor inhibitors will result high platelet reactivity (HPR) and patients who exhibit HPR are at increased risk of atherothrombotic occlusion events. Vice versa, high response to P2Y12 receptor inhibitors will lead to low platelet reactivity (LPR) and increase the risk of hemorrhage.Now, the absence of a universal definition of therapeutic window for different racial and actual clinical situations and lacking the gold standard test to quantify it limit the use in clinic practice.So this clinical trial try to use patient's platelet reactivity combine with type of adverse reaction, forms, influencing factors to find a proper therapeutic windows for P2Y12 receptor inhibitors in Chinese people.
