Single Catheter Primary Percutaneous Coronary Intervention Method in Patients With ST Elevation Myocardial Infarction

The goal of this clinical trial is to test reducing procedure time of percutaneous coronary intervention (PCI) in ST elevation myocardial infarction by single catheter PCI (SC-PCI) method. The main question it aims to answer is:• [question 1] SC-PCI method is skipping catheter exchange with use of a right and left dual purpose universal guiding catheter Ikari Left curve. Does SC-PCI method reduce PCI procedure time? Participants will be randomly assigned to SC-PCI method or conventional method and emergency PCI is performed.Researchers will compare time from sheath insertion to first device activation between the SC-PCI method and the conventional method.

Inclusion Criteria:Age of 21 years or olderAcute ST-segment elevation myocardial infarctionPatients indicated for Primary PCI within 12 hours after onsetExclusion Criteria:Patients with shock requiring insertion of Impella, ECMO or IABP before PCIPatients requiring cardiopulmonary resuscitation due to cardiac arrestPatients requiring temporary pacemaker due to bradycardiaPatients undergoing dialysisPatients judged by the attending physician to be inappropriate for registration
