COOL AMI EU Pilot Trial to Assess Cooling as an Adjunctive Therapy to Percutaneous Intervention in Patients With Acute Myocardial Infarction

COOL AMI EU Pilot Trial: A Multicenter, Prospective, Randomized Controlled Trial to Assess Cooling as an adjunctive Therapy to Percutaneous Intervention in Patients with Acute Myocardial Infarction.

Evaluate the retention of subjects after integrating therapeutic hypothermia using the ZOLL Proteus IVTM System into existing STEMI treatment protocols for subjects who present with acute anterior myocardial infarction.

Evaluate the retention of subjects after integrating therapeutic hypothermia using the ZOLL Proteus IVTM System into existing STEMI treatment protocols for subjects who present with acute anterior myocardial infarction.

Eligibility Criteria:

5. Opportunity for at least 10 minutes of cooling with the Proteus IVTM System prior to PCI.
6. Written, informed consent to participate in this clinical trial.

Exclusion Criteria:

All Exclusion Criteria must be answered NO for subject to be eligible for trial inclusion.

1. Previous myocardial infarction.
2. Cardiogenic shock (systolic blood pressure \[SBP\] \<80 mmHg and non-responsive to fluids, or SBP \<100 mmHg with vasopressors, or requirement for an intra-aortic balloon pump \[IABP\]).

7. Previous CABG.
8. Stroke within 90 days of admission.
9. Cardio-pulmonary decompensation present or imminent
10. Contraindications to hypothermia, such as patients with known hematologic dyscrasias which affect thrombosis (e.g., cryoglobulinemia, sickle cell disease, serum cold agglutinins) or vasospastic disorders (such as Raynaud's or thromboangitis obliterans)
