Do Opioid Addicts Require Higher Doses of Heparin During Percutaneous Coronary Intervention?

Background: Patients who undergo percutaneous coronary intervention (PCI) receive anticoagulants, most commonly heparin to prevent thrombotic events during the procedure. Opioid addicts may require higher doses of heparin for PCI. We aimed to compare the effect of heparin on activated clotting time (ACT) between opioid addicts and non-addicts prior to and during PCI.

Compare Complication of Classic versus Patent Hemostasis in Transradial Coronary Angiography.

Background: Coronary artery disease (CAD) is multifactorial disease, in which thrombotic occlusion and calcification occur usually. New strategies have been made for diagnosis and treatment of CAD, such as transradial catheterization. Hemostasis could be done in two approaches: traditional and patent.
