Target Temperature Management In Myocardial Infarction - A Pilot Study
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.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Pre- and perinterventional hypothermia
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.

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)

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
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
Lasso di tempo: Time of reperfusion of the culprit lesion in st-elevation myocardial infarction (expected average 120 minutes)
|
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)

Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Safety of a combined cooling strategy as an adjunctive therapy on primary percutaneous coronary intervention in acute st-elevation myocardial infarction
Lasso di tempo: within 45 days (+/- 15 days)
|
Incidence of major adverse cardiac events as defined as: death, heart failure, pulmonary edema, recurrent MI, malignant arrhythmias (i.e.
ventricular fibrillation, sustained ventricular tachycardia) emergent stent revascularisation, any hospitalisation, major/minor bleeding (according to TIMI-bleeding score), infection (clinical relevant infection with the need of systemic antimicrobiotic therapy) within a period of 45±15 days
|
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
Lasso di tempo: during active cooling and rewarming (in average the first 4 hours)
|
Patients are monitored for incidence of shivering using a 4-point scale: 0, no shivering evident; 1, isolated facial or masticatory fasciculation; 2, peripheral shivering; 3, uncontrolled rigor during the cooling procedure (in average the first 4 hours)
|
during active cooling and rewarming (in average the first 4 hours)
|
|
Time to revascularisation (first medical contact to balloon time)
Lasso di tempo: Time of reperfusion (in average 120 minutes)
|
The time to reperfusion of the infarct related artery is crucial in acute ST-elevation myocardial infarction.
To evaluate if the cooling procedure has a substantial influence on this time frame we measure the time from first medical contact to reperfusion.
