[Fibrinopeptide A and protein C in heart patients with acute coronary syndromes].
In order to determine the role of thrombosis in the acute coronary syndromes the blood levels of fibrinopeptide A and protein C were examined with an enzyme-immune test in 48 patients treated in the cardiological clinic of the National Centre for Cardiovascular Diseases. 27 patients were with transmural myocardial infarction and 21 patients were with non-transmural myocardial infarction. The average time of the test from the onset of pain is 18.4 +/- 12.2 hours (from 3 up to 72 hours). The mean level for fibrinopeptide A for the whole group of patients is 4.95 +/- 3.1 ng/ml and that of protein C is 70.1 +/- 9.8%. For the group of patients with transmural myocardial infarction the level of fibrinopeptide A is 6.09 +/- 3.49 ng/ml and of protein C is 65.3 +/- 8.0%. For the patients with nontransmural myocardial infarction the levels are respectively 3.49 +/- 1.7 ng/ml for fibrinopeptide A and 76.3 +/- 8.3% for protein C. The difference between the two groups is statistically significant (p less than 0.005). In the patients with non-transmural myocardial infarction from whom the blood for the test was taken before the 24th hour the fibrinopeptide A level is 4.8 +/- 2.4 ng/ml and the protein C level is 69.0 +/- 7.8%. The deviations from the reference group are statistically significant (p less than 0.04). The practical importance of these results is discussed.
