A controlled trial of intramuscular lidocaine in the prevention of premature ventricular contractions associated with acute myocardial infarction.

abstract：BACKGROUND:Bivalirudin is shown to be a competent substitute for heparin in percutaneous coronary intervention (PCI). The safety and efficacy of bivalirudin in patients undergoing PCI and vascular brachytherapy (VBT) are not known. This study aimed to assess the safety and efficacy of bivalirudin as a single antithromb...
