Overview
Brief Summary
The purpose of the study is to investigate the clinical outcomes, safety and cost-effectiveness of intravascular OCT imaging in patients with acute myocardial infarction undergoing percutaneous coronary intervention (PCI). About 4500 patients with acute myocardial infarction (estimated 1500 with OCT guidance and 3000 without OCT guidance during PCI）will be prospectively enrolled in 20 sites in China. The total duration of the study is expected to be 5 years, 2 years for enrolment and 3 years for follow up.
Detailed Description
This is a prospective, multi-center, non-randomized, observational registry study of patients with acute myocardial infarction (AMI) that require catheterization. The purpose of this registry is to investigate the clinical outcomes, safety and cost-effectiveness of intravascular OCT imaging in patients with AMI undergoing PCI.The duration of the study is expected to be 5 years, 2 years for enrolment and 3 years for total follow up.The clinical study will be conducted in 20 centers in China.Approximately 4500 subjects (1500 with OCT imaging and 3000 without OCT imaging) will be enrolled in this study.Subjects will be followed up at 1, 3, 6, 12months and every 6 months afterwards up to 5 years. All subjects need to be followed for at least 12 months.

Eligibility Criteria
Inclusion Criteria
- •Patients presenting with:a.Symptoms of myocardial ischemia lasting for ≥ 30 minutes.b.Definite ECG changes indicating STEMI: ST elevation of greater than 0.1 mV in two contiguous limb leads or 0.2 mV in two contiguous precordial leads, or presumed new left bundle branch block. c. NSTEMI
- •Referred for primary PCI.
- •Are able to provide written Informed Consent prior to any study related procedure.
Exclusion Criteria
- •Patient who is unable to comply with the follow-up schedule.
- •Left main occlusion
- •Unable to restore TIMI flow grade III before stenting
- •Prior coronary artery bypass surgery (CABG)
- •Cardiogenic shock

Outcomes
Primary Outcomes
Major cardiovascular adverse events rate
Time Frame: 1 year
In patients treated conservatively, the safety objectives are to evaluate the occurrence of any adverse events in 1 year (re-infarction, re-hospitalization, revascularization by PCI or CABG, cardiac death, stoke, and major bleeding)
Secondary Outcomes
- The incidence of procedural complications(baseline)
- The rate of procedural strategy changes during the primary PCI(baseline)
- Major cardiovascular adverse events rate(2 and 3 year)
- the indience of different plaque characteristic in the setting of STEMI(baseline)
