Minimal antegrade flow may limit infarct size; leaves open whether preserving TIMI 1 flow improves outcomes in primary PCI.
Does residual flow (antegrade or collateral) before direct angioplasty reduce infarct size in patients with acute evolving myocardial infarction?
The presence of residual antegrade or collateral flow to the infarct zone before direct angioplasty in acute myocardial infarction is associated with smaller final infarct size and greater myocardial salvage.
