GASTROINTESTINAL BLEEDING, THROMBUS
The low‐molecular‐weight heparin (LWMH) (100 IU/kg, injected subcutaneously every 12 h) is recommended for up to 7 days during the perioperative period. Dabigatran is required to be prescribed after randomization and discontinuation of the LWMH. A bolus of unfractionated heparin (UFH) (100 IU/kg) should be injected intravenously during the PCI procedure. The activated clotting time (ACT) should be monitored every 1 h and an extra UFH should be administered if the ACT is low than 300 s. The platelet glycoprotein IIb/IIIa receptor inhibitors, e.g., Tirofiban, are not recommended unless a heavy thrombus burden is shown in coronary angiography. Other antithrombotic agents, e.g., prasugrel or rivaroxaban, are not allowed to be administered during the study period. Proton pump inhibitors could be administered for patients with high risk of gastrointestinal bleeding. Other medications (e.g., statins, β‐blockers, angiotensin‐converting enzyme inhibitors, etc.) could be administered at the discretion of the attending physicians.
