Factors associated with myocardial salvage immediately after emergent percutaneous coronary intervention in patients with ST-elevation acute myocardial infarction

Abstract

This study demonstrated that patients with a greater improvement of (99m)Tc tetrofosmin myocardial uptake immediately after PCI had better recovery of left ventricular function and smaller final infarct size. Reperfusion time and TIMI flow grade </=2 after PCI were important determinants of myocardial salvage, and nicorandil was a major determinant of myocardial salvage.

Technetium-99m tetrofosmin: Use for myocardial perfusion imaging in the detection of coronary artery disease

“…In terms of its utility in determining the long-term fate of salvaged myocardial tissue, there has been a recent report of a study of patients with ST-segment elevation acute myocardial infarction, which showed that greatly improved technetium-99m tetrofosmin myocardial uptake immediately after treatment heralded better recovery of left ventricular function and smaller final infarct size (one month after emergent percutaneous coronary intervention). 65…”
