COmprehensive Remote Ischemic Conditioning in Myocardial Infarction (CORIC-MI)
Myocardial Infarction, Anterior Wall
About this trial
This is an interventional treatment trial for Myocardial Infarction, Anterior Wall focused on measuring Remote Ischemic Conditioning
Eligibility Criteria
Inclusion Criteria:
- Suspected anterior STEMI: new ST-elevation > 0.1 millivolt (mV) (≥ 0.2 mV in men or ≥ 0.15 mV in women in leads V2-V3) in > two contiguous leads in V1-V6; new or presumed new left bundle branch block;
- Symptom onset no more than 12 h before presentation and planned primary PCI;
- Age 18 to 75 years;
- Willingness and capability to provide informed consent.
Exclusion Criteria:
- Previous anterior myocardial infarction;
- Previous coronary artery bypass graft (CABG);
- Myocardial infarction or stroke within the previous 30 days;
- Treatment with thrombolysis within the previous 30 days;
- Cardiogenic shock;
- Thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3 at coronary angiography;
- Coronary anatomy or mechanical complication of STEMI (ventricular septal rupture, free wall rupture, acute severe mitral regurgitation) warranting emergent surgery;
- Inability to obtain TIMI flow grade ≥ 2;
- Conditions precluding use of RIC (paresis of lower limb, known severe peripheral artery disease or evidence of lower limb ischemia, and etc.);
- Life expectancy of less than 12 months due to non-cardiac disease such as known malignancy or other comorbid conditions;
- Contraindications to CMR;
- Treated with therapeutic hypothermia before admission;
- Pregnancy and lactating women;

Non-CORIC
Comprehensive remote ischaemic conditioning (CORIC) will be induced using an automated RIC device: Per-RIC consists of 5 cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuff on a lower limb. The first inflation began immediately following randomization after admission. In case 5 cycles of RIC were not fully completed when the first balloon inflation or thrombus aspiration was ready to be performed, PCI was not to be delayed. Post-RIC consists of 5 cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuff on a lower limb immediately after PPCI. Delayed-RIC consists of 5 cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuff on a lower limb once daily on 2-28 days after MI.
Controls did not undergo comprehensive remote ischaemic conditioning.
