| Popis: | Aim. To assess the relationship between fibrosis markers and structural and functional parameters in patients with various types of hypertrophic cardiomyopathy (HCM).Material and methods. This prospective comparative non-randomized study included 49 patients with HCM. Patients were divided into 3 groups according to the disease course: group 1 — stable course (n=12; men, 8 (67%), mean age ‒ 41±12 years); group 2 — progressive course (n=26; men, men, 16 (61%). mean age — 57±11 years); group 3 — patients with atrial fibrillation (AF) (n=11; men, 4 (36%), mean age — 63±6 years). Patients underwent standard clinical and paraclinical investigations. The levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) were determined in all patients using enzyme-linked immunosorbent assay in blood serum.Results. In all patients with HCM, elevated levels of MMP-9 and TIMP-1 are noted compared to the reference values. In group 1, the MMP-9 level [Me (Q1; Q3)] was 226 (201;271) ng/ml; TIMP-1 — 410 (267;488) ng/ml; in group 2, the MMP-9 level was 236 (187;285) ng/ml; TIMP-1 — 421 (321;499) ng/ml. In the course with AF, the MMP-9 level was 260 (228;296) ng/ml, while TIMP-1 — 381,5 (305;466) ng/ml; no significant difference was revealed (p=0,59; p=0,90, respectively). A correlation was found between age and MMP-9 levels, as well as between MMP-9 levels and left atrial volume (p=0,034; p=0,035, respectively).Conclusion. The high activity of matrix metalloproteinases and their tissue inhibitors reflects enhanced fibrosis and myocardial remodeling in HCM, which is especially characteristic of patients with AF. |
