thrombolysis in myocardial infarction score
Pronunciation: TIE-mee
Also written as: TIMI — Thrombolysis in Myocardial Infarction
A standardized grading system for coronary blood flow used in cardiac catheterization procedures.
Full Definition
The Thrombolysis in Myocardial Infarction (TIMI) score is a widely used classification system that grades coronary blood flow from 0 to 3, where TIMI 0 indicates complete occlusion and TIMI 3 represents normal flow. Originally developed for clinical trials of thrombolytic therapy, the TIMI flow grade is now routinely used to assess procedural success in percutaneous coronary interventions. The scoring system helps standardize reporting of angiographic results and correlates with clinical outcomes.
Usage
Usage note: Always specify the numerical grade (0-3) when documenting TIMI flow.
In Context
- "Post-intervention angiography demonstrated TIMI 3 flow in the left anterior descending artery." — Cardiac catheterization report
- "The patient achieved TIMI 2 flow after thrombolytic therapy, indicating partial reperfusion." — STEMI treatment summary
