Evaluation of Ultrafast Hypothermia Before Reperfusion in STEMI Patients

VELOCITY: Pilot Study to Evaluate Ultrafast Hypothermia Before Reperfusion in Patients With Acute ST-Elevation Myocardial Infarction

This study will look at the safety of treating patients with heart attack with mild hypothermia induced using a system of automated peritoneal lavage. The hypothesis is that the Velomedix Automated Peritoneal Lavage System can treat patients with heart attack safely and with adequate performance.

The study aims to determine the safety and feasibility of using the Velomedix Automated Peritoneal Lavage System to treat patients with STEMI using therapeutic hypothermia. Patients will undergo cooling, maintenance and rewarming and applicable data will be gathered on device performance and patient safety. Patient temperature and vital signs will be monitored in addition to various laboratory values. Adverse event reporting will take place at multiple time intervals and follow-up will continue out to 6-months.

Inclusion Criteria:

• Clinical symptoms consistent with acute STEMI lasting at least 30 minutes
• STEMI with ST-Elevation of ≥2 mm in two or more contiguous ECG leads
• Patient eligible for PCI

Exclusion Criteria:

• Cardiac arrest with return of spontaneous circulation
• Known prior history of MI
• Known history of severe COPD requiring supplemental home oxygen
• Patient experiencing intractable cardiogenic shock, or requiring immediate placement of a mechanical cardiac assist device
• Known severe anemia or abnormal platelet count
• Known significant renal insufficiency
• Known contraindication for MRI
• Known contraindications to hypothermia, such as temperature-sensitive hematological dyscrasias or vasospastic disorders
