May reflect acute thrombotic processes in unstable angina; extends pathophysiologic understanding but leaves open clinical utility.
Do plasma fibrinopeptide A and platelet factor levels differ between patients with unstable and stable angina?
Elevated fibrinopeptide A levels in unstable angina indicate activation of the coagulation system, distinguishing it from stable angina.
Théroux et al. (1987) studied this question.
