Brief Summary:
This study is a prospective, multi-center, non-inferior, randomized controlled clinical trial, aims to use optical Coherence tomography to observe the the early- and mid-stage vessel repair and neointimal proliferation. And to assess the safety and effectiveness of the Firehawk™ sirolimus target-eluting coronary stent system with abluminal grooves containing a biodegradable polymer (Firehawk™) comparing the XIENCE everolimus-eluting coronary stent system in the treatment of subjects with ST-elevation myocardial infarction (STEMI).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 44 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Assessment of In-stent Intimal Repair and Vessel Reaction After FirehawkTM Sirolimus Eluting Stent Implantation of STEMI Subjects - An Optical Coherence Tomography (OCT) Study
Actual Study Start Date : March 8, 2019
Estimated Primary Completion Date : December 1, 2020
Estimated Study Completion Date : December 1, 2021

Arm Intervention/treatment
Experimental: Firehawk implantation
22 subjects will be enrolled to receive Firehawk™ sirolimus target-eluting stent(s).
Procedure: percutaneous coronary intervention
Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is a nonsurgical procedure that improves blood flow to your heart.PCI requires cardiac catheterization, which is the insertion of a catheter tube and injection of contrast dye, usually iodine-based, into your coronary arteries. Doctors use PCI to open coronary arteries that are narrowed or blocked by the buildup of atherosclerotic plaque. PCI may be used to relieve symptoms of coronary heart disease or to reduce heart damage during or after a heart attack.
Other Name: PCI

Active Comparator: XIENCE implantation
