Recruitment & Eligibility

• Status: Recruiting
• Sex: All
• Target Recruitment: 676

Inclusion Criteria

1) Age = 19 years old
2) Non-ST-segment elevation myocardial infarction
** Angina pectoris or equivalent ischemic chest discomfort with at least 1 of 3 features and,
# occurs at rest, usually lasting > 10 minutes
# severe and new onset (within the prior 4-6 weeks)
# crescendo pattern
** Elevated cardiac biomarkers and,
# = 99% value of high-sensitivity cardiac troponin
** No ST-segment elevation = 0.1 mV in = 2 contiguous leads or newly developed left bundle branch block on 12-lead electrocardiogram
3) PCI within 72 hours after symptom development
4) Multivessel disease: Non-IRA with at least 2.5 mm diameter and 50% diameter stenosis by visual estimation
5) Patient's or protector's agreement about study design and the risk of PCI

Exclusion Criteria

1) Cardiogenic shock at initial presentation or after treatment of infarct-related artery(IRA)*
2) Thrombolysis in Myocardial Infarction(TIMI) flow at non-IRA = 2 at initial coronary angiography
3) Severe procedural complications (e.g. persistent no-reflow phenomenon, coronary artery perforation) which restricts study enrollment by operators' decision
4) Non-IRA lesion not suitable for percutaneous coronary intervention(PCI) treatment by operators' decision
5) Chronic total occlusion at non-IRA
6) History of anaphylaxis to contrast agent
7) Pregnancy and lactation
8) Life expectancy < 1-year due to non-cardiac disease
9) Severe valvular disease
10) History of coronary artery bypass graft(CABG), or planned CABG
11) Severe asthma
12) Patient's refusal for study participation

* The definition of cardiogenic shock
1) Systolic blood pressure(SBP) < 90mmHg for more than 30min, or needs for vasopressor to maintain equal or more than SBP 90mmHg
2) Pulmonary congestion, or increased left ventricular filling pressure by cardiac catheterization
3) At least one sign of impaired organ perfusion: mental obtundation, pallor, coldness, oliguria, increased blood lactate
