Brief Summary
To evaluate the safety and efficacy of the MGuard™ Prime stent in the treatment of blocked arteries in coronary arteries in patients undergoing a stenting procedure due to having a heart attack. The MGuard Prime stent wil be compared to other FDA approved bare-metal (BMS) or drug-eluting (DES) coronary stents. The hypotheses are that (1) the MGuard Prime stent will achieve a higher rate of complete ST-segment resolution as seen on the post-procedure ECG as compared to the comparator stent, and will have a similar effect on the rate of all-cause death or recurrent target vessel myocardial infarction at 365 days post-procedure.

Outcome Measures
Primary Outcomes (2)
rate of complete ST-segment resolution within 60-90 minutes
60-90 minutes post-procedure
The primary safety endpoint is a composite of all-cause death or recurrent target vessel myocardial infarction (TV re-MI) at 365 days post-procedure, powered to demonstrate non-inferiority of the MGuard™ Prime Stent compared to the control arm.
365 days post-procedure
Secondary Outcomes (2)
Infarct size assessed by cardiac magnetic resonance imaging (MRI)
5 days post-procedure
In-stent late lumen loss (LLL)
13 months post-procedure
Study Arms (2)
MGuard Prime
EXPERIMENTALMGuard Prime stent
Control
ACTIVE COMPARATOR(BMS/DES) Includes FDA approved bare metal or drug eluting stents, including ENDEAVOR, TAXUS Liberte, XIENCE Prime, PROMUS Element, ION, RESOLUTE, Driver, Vision, VeriFlex and Integrity.

Eligibility Criteria
You may qualify if:
- Subject is more than 18 years of age
- Subject is experiencing clinical symptoms consistent with acute myocardial infarction (AMI) of more than 30 minutes and less than 12 hours in duration.
- ST elevation more than 2 mm per lead in more than 2 contiguous leads is present in one ECG prior to consent.
- Subject agrees to all required follow-up procedures and visits.
- Subject or legal representative provides written, informed consent.
- The target lesion is a de novo lesion in a native coronary artery.
- Based on coronary anatomy, PCI is indicated for the culprit lesion with anticipated use of stenting.
- The reference vessel diameter (RVD) of the infarct lesion is 2.75 to 4.0 mm by visual assessment, assessed either at baseline (if direct stenting is planned), or after pre-dilatation or thrombus aspiration (if direct stenting is not planned).
- The entire lesion length requiring treatment is less than 24 mm (able to be covered by a single study stent), assessed either at baseline (if direct stenting is planned), or after pre-dilatation or thrombus aspiration (if direct stenting is not planned)
- TIMI flow of 2/3 is present prior to randomization (in case of baseline TIMI flow 0/1, blood flow must be restored).
You may not qualify if:
- Left bundle branch block (LBBB), paced rhythm, or other ECG abnormality interfering with assessment of ST-segment.
- Currently enrolled in another investigational device or drug trial that has not completed the primary endpoint or that clinically interferes with the current study endpoints.
- A previous coronary interventional procedure of any kind within 30 days prior to the procedure.
- Female patients of childbearing potential.
- Subject undergoing cardiopulmonary resuscitation (patients in whom cardiopulmonary resuscitation was successfully performed and in whom normal mental status was achieved, may be enrolled).
- Cardiogenic shock (SBP less than 80 mmHg for more than other hemodynamic support device for hypotension).
- The subject requires a staged procedure of the target vessel (including branches) within 12 months or of any non-target vessel within 7 days post-procedure.
- The target lesion requires treatment with a device other than PTCA prior to stent placement (such as, but not limited to excimer laser, rotational atherectomy, etc.). Manual thrombus aspiration may be used per operator discretion, but rheolytic thrombectomy is only permitted for procedural complications after randomization.
- Prior administration of thrombolytic therapy for the current admission
- Co-morbid condition(s) that could limit the subject's ability to participate in the trial or to comply with follow-up requirements, or impact the scientific integrity of the trial.
- Concurrent medical condition with a life expectancy of less than 12 months.
- History of cerebrovascular accident or transient ischemic attack within the last 6 months, or any permanent neurologic deficit
- Prior intracranial bleed at any time, or known intracranial pathology (e.g. tumor, arteriovenous malformation, or aneurysm).
- Active or recent site of major bleeding within 6 months.
- History of bleeding diathesis or coagulopathy or inability to accept blood transfusions.
