Pronunciation: TIE-mee
Also written as: TIMI — Thrombolysis in Myocardial Infarction
Standardized angiographic grading system for coronary blood flow assessment.
Full Definition
The Thrombolysis in Myocardial Infarction flow grade is a standardized classification system used to assess coronary artery perfusion during angiography. TIMI flow ranges from 0 (no perfusion) to 3 (normal perfusion), with grades 1 and 2 representing partial perfusion. This grading system is essential in emergency cardiology for evaluating procedural success and predicting clinical outcomes following interventions.
Usage
Usage note: Always specify the grade number (0-3) when documenting.
In Context
- "Post-intervention angiography demonstrated TIMI 3 flow in the previously occluded vessel." — Procedure report
- "The patient presented with TIMI 0 flow in the right coronary artery." — Emergency department note
