The study of the specifity of qualitative immunochromatographic method of identifying heart-type fatty acid-binding protein applied to cardiovascular patients without recent acute coronary syndrome

The research was aimed at studying the peculiarities of qualitative immunochromatographic method of identifying heart-type fatty acid-binding protein (h-FABР) applied to patients without acute coronary syndromе. The group consisted of 31 patients (average age - 66,69±2,17 years old) with wide range of cardiovascular diseases and without clinical signs of acute coronary syndromе within 15 days before the test. All patients underwent immunochromatographic express-test defining the level of h-FABР 15 ng/ml which is diagnostic for acute myocardial infarction. Serial determination of creatin kinase-MB was performed to patients with positive express-test h-FABР. Specificity of the express-test h-FABР was 90,6%. It was proved that clinical laboratory characteristics, comorbid pathology, medical treatment received by the patients do not have significant influence on the results of the given diagnostic method.
