All Rights Reserved. 57 men and 43 women, aged 22.0±4.2 years were examined to determine the clinical and prognostic value of matrix metalloproteinases in heart remodeling in CTD. Serum concentrations of MMP-1, MMP-9, TIMP-1 were determined by ELI-SA («Cloud-Clone Corp.», China). Imbalance of MMP-1, MMP-9 and their inhibitor - TIMP-1 was revealed in patients with CTD. Significant increase in MMP-1 level was registered in cases of MVP with myxomatous degeneration and mitral regurgitation of II degree. Risk of cardiac remodeling progression at three-year follow-up increases in cases of elevated of MMP-1/TIMP-1 coefficient. Identified changes in the MMPs system in patients with CTD may be used as additional criteria of severity and determination of probability of progression of heart connective tissue structures remodeling.
