Patients recovering from unstable angina or myocardial infarction exhibit a persistent hypercoagulable state for at least 6 months, highlighting ongoing thrombotic risk.
During the acute phase of unstable angina and myocardial infarction, patients exhibit increased coagulation system activity. Over the next 6 months, patients with unstable angina or myocardial infarction experiencing an uneventful clinical course manifest a persistent hypercoagulable state with minimal generation of fibrin.
Merlini et al. (Fri,) studied this question.
