Reduce Bolus Injection of Bivalirudin
Acute Coronary Syndrome

About this trial
This is an interventional treatment trial for Acute Coronary Syndrome focused on measuring bivalirudin, bolus injection, activated clotting time, Renal insufficiency

This arm, we will choose the patients who's eGFR ≥60ml/min and reduce the bivalirudin bolus injection dose to 80% of the standard dose in clinical practice, and we will adjuste the bivalirudin maintenance dose and rate according to the ACT time during surgery to reduce the ACT value caused by the bolus injection.
