Abstract
Background: A-FABP is a promising link between metabolic syndrome and atherosclerosis. It is not well known whether level of A-FABP predicts results of SPECT. Patients & methods: In 82 subjects (53 males) with a median age of 54 years, who were first-degree relatives of patients with cardiovascular disease, the following tests and examinations were performed: A-FABP, calcium score (CS) and SPECT. Results: Subjects with positive and negative SPECT results differed significantly in the noncategorized CS (p = 0.001), uric acid (p = 0.025) and the total cholesterol:high-density lipoprotein ratio (p = 0.043), but not in other parameters (including A-FABP). To predict SPECT results, the best model proved to be a logistic regression model with gender and noncategorized CS as predictors, with an area under the receiver operating characteristic curve of 0.89 (the sensitivity and specificity based on a CS cutoff of 11.1 were 77.78 and 75.34%, respectively). Conclusion: The serum level of A-FABP is not a predictor of a positive SPECT result.
