Cooling and dilution during heart attack treatment to protect the heart

Trans-coronary Cooling and Dilution for Cardioprotection During Revascularisation for ST-elevation Myocardial Infarction

Not applicable Interventional Royal Brompton & Harefield NHS Foundation Trust · NCT06128993

This study is testing if cooling and diluting the blood during heart attack treatment can help protect the heart and improve recovery for patients undergoing a specific procedure.

What this trial studies

This pilot trial involves 60 patients with ST-Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) at Harefield Hospital. The study aims to assess the feasibility and safety of using trans-coronary cooling and dilution during PCI to reduce the size of myocardial infarction. Patients will be randomly assigned to receive either the cooling intervention or standard care, with evaluations of coronary flow, microvascular function, and myocardial salvage through MRI. The study will also analyze blood biomarkers before and after the intervention.

Who should consider this trial

Good fit: Ideal candidates are individuals presenting with ST-elevation myocardial infarction within 12 hours of symptom onset.

Not a fit: Patients with severe asthma, pregnancy, or severe concomitant diseases with a life expectancy of less than one year may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce heart damage during heart attacks, improving patient outcomes.

How similar studies have performed: While similar approaches have been explored, this specific method of trans-coronary cooling and dilution is relatively novel and has not been extensively tested.
