Final Myocardial Blush Grade Predicts Troponin I Elevation in Unstable Angina Patients Undergoing Percutaneous Intervention

Improved blush grade in UA patients undergoing PCI is associated with lower post-procedural TnI elevation. Identification of UA patients with poor final MBG may allow a window of opportunity for the administration of adjuvant therapies to improve microvascular perfusion in the future.
