Risk Score of Sabatine et al for a Patient with Unstable Angina Pectoris

Purpose: To evaluate a patient with unstable angina pectoris using the risk score of Sabatine et al.

Description

Sabatine et al developed a risk score for patients with unstable angina pectoris. This can help identify patients who have a survival benefit associated with therapy with glycoprotein IIb/IIIa inhibitor therapy. The authors are from Massachusetts General Hospital, Montreal Heart Institute and Merck Research Laboratories.


Parameters:

(1) age in years

(2) history of coronary artery bypass

(3) antecedent aspirin use

(4) antecedent beta-blocker use

(5) ST wave on presenting ECG

= SUM(points for all 5 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 5

• A higher score indicates greater risk of an endpoint (myocardial infarction, death, refractory ischemia) at 7 days.
