residual platelet reactivity, thrombus burden and myocardial reperfusion in patients treated by pci after successful pre-hospital fibrinolysis compared to primary pci

We compared residual platelet reactivity and post pci atherothrombotic burden using ofdi in patients successfully treated by primary pci versus pharmacoinvasive approach (pi) defined as pci after successful pre-hospital fibrinolysis. despite pre-hospital p2y12-inhibitor loading dose, high rates of high on-treatment platelet reactivity were found at the time of pci in both groups. primary pci patients had higher post stenting thrombus burden and lower rates of final normal myocardial blush grade compared to pi. these findings support the use of a pharmacoinvasive reperfusion strategy especially when primary pci cannot be timely performed.
