Frequently Asked Questions
What is the TIMI Risk Score for UA/NSTEMI used for?
It estimates the 14-day risk of death, new or recurrent heart attack, or need for urgent revascularization in patients with unstable angina or non-ST-elevation myocardial infarction (NSTEMI), using 7 simple clinical criteria.
How does this differ from the STEMI version?
This version applies to unstable angina and NSTEMI (a less severe type of heart attack without full-thickness ST elevation on ECG), while the separate TIMI STEMI score applies specifically to ST-elevation heart attacks and uses different criteria.
What does a high TIMI UA/NSTEMI score suggest?
Higher scores are associated with progressively higher 14-day risk and are often used to help decide on the urgency of invasive treatment strategies, such as early cardiac catheterization.
Is this calculator a substitute for medical advice?
No. This is an educational reference implementation of the standard TIMI UA/NSTEMI risk score, not a substitute for a physicians clinical assessment.
