Relationship between the duration of ischemia and final infarct size in STEMI patients treated with abciximab and primary PCI

We studied 89 patients with first time myocardial infarction and treated with primary PCI. There was only a weak correlation between ischemia duration and final myocardial scar size measured with ceMRI six weeks later. Other factors like anterior infarction, a patent artery pre-PCI and effects of reperfusion injury may have had greater influence on infarct size than time-to-treatment per se.
