(A) Individual distribution of FVIIa results determined by ELISA in patients presenting with noncardiac chest pain (NCP), unstable angina (UAP), and myocardial infarction (MI). The significance of differences between results of noncardiac chest pain group and (A) unstable angina group, and (B) all patients with acute coronary syndromes, is indicated by the P value. (B) Individual distribution of F1 + 2 results determined by ELISA in patients presenting with noncardiac chest pain (NCP), unstable angina (UAP), and myocardial infarction (MI). The significance of differences between results of noncardiac chest pain group and (A) myocardial infarction group, and (B) all patients with acute coronary syndromes, is indicated by the P value.
