Adjunctive Devices for Patients With Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention
Thrombolysis in Myocardial Infarction Flow Grading System Defined
This table defines the thrombolysis in MI (TIMI) flow grading system. For grade 0, there is complete occlusion of the infarct-related artery. In grade 1, there is some penetration of contrast material beyond the point of obstruction but without perfusion of the distal coronary bed. In grade 2, there is perfusion of the entire infarct vessel into the distal bed but with delayed flow when compared with a normal artery. In grade 3, there is full perfusion of the infarct vessel with normal flow.
