NCT01864343

Brief Summary

The primary goal in the treatment of acute myocardial infarction is to reperfuse the ischemic myocardium to reduce infarct size. Animal data and human data suggest that whole-body cooling to temperatures below 35°C before revascularisation can additionally reduce infarct size and therefore improves outcome in these patients. The purpose of the study is to determine the feasibility and safety of a combined cooling strategy started in the out-of-hospital arena for achieving pre-reperfusion hypothermia in patients with acute st-elevation myocardial infarction.

Outcome Measures

Primary Outcomes (1)

  • Feasibility of a combined cooling strategy for achieving a core temperature of <35.0°C at the time of reperfusion of the infarct related artery

    Blood temperature will be recorded at the time of first wire-crossed lesion of the infarct related coronary stenosis

    Time of reperfusion of the culprit lesion in st-elevation myocardial infarction (expected average 120 minutes)

Secondary Outcomes (3)

  • Safety of a combined cooling strategy as an adjunctive therapy on primary percutaneous coronary intervention in acute st-elevation myocardial infarction

    within 45 days (+/- 15 days)

  • Tolerability of a combined cooling strategy as an adjunctive therapy on primary percutaneous coronary intervention in acute st-elevation myocardial infarction

    during active cooling and rewarming (in average the first 4 hours)

  • Time to revascularisation (first medical contact to balloon time)

    Time of reperfusion (in average 120 minutes)

Study Arms (1)

Pre- and perinterventional hypothermia

EXPERIMENTAL

Cooling will be initiated by the application of cooling pads in the out-of-hospital setting followed by an infusion of 1000-2000ml of cold saline. In the cath lab a endovascular cooling catheter will be placed into the inferior vena cava via a femoral vein to achieve a core temperature of \<35°C prior to revascularization.

Device: EMCOOLS flex pad; Philips Innercool RTx

Interventions

Surface cooling with EMCOOLS flex pads (out-of-hospital); Infusion of 1000ml to 2000ml of cold saline (out-of-hospital); central-venous cooling (Philips Innercool RTx)

Pre- and perinterventional hypothermia
