What Researchers Did
Researchers reviewed the current understanding of myocardial reperfusion injury and potential cardioprotective therapies for patients with ST-segment elevation myocardial infarction (STEMI).
What They Found
Despite timely reperfusion therapy for ST-segment elevation myocardial infarction (STEMI) being effective in limiting infarct size, patient morbidity and mortality remain significant due to myocardial reperfusion injury (RI). Currently, there is no effective therapy to prevent RI, with previous attempts using agents like antioxidants and calcium-channel blockers proving unsuccessful, though mechanical strategies such as ischaemic post-conditioning show promise.
What This Means for Canadian Patients
Canadian patients experiencing a heart attack (STEMI) currently benefit from timely reperfusion, but still face risks from reperfusion injury, for which no effective treatment exists. Future research into mechanical cardioprotective strategies could potentially offer new ways to further improve outcomes and reduce complications for these patients.
