Abstract
Aim. To study the level of matrix metalloproteinases-1 and -2, and tissue inhibitor of metalloproteinases-1, the indicator of left ventricular myocardial deformation in patients with stage 1–2 hypertension.
Methods. 114 patients (40 women and 74 men) with hypertension of 1–2 stages observed in the cardiology “Department of the Road clinical hospital Chita II” were examined. The median age was 42±8.3 years. Left ventriclular diastolic function was studied by using tissue Doppler imaging in apical four-chamber views. Serum matrix metalloproteinase-1, matrix metalloproteinase-2, and tissue inhibitor of metalloproteinases-1 levels were measured in all patients on automated immunoassay analyzers using ready-to-use ELISA kits.
Results. An increase in serum levels of matrix metalloproteinases-1 and -2 in the group of patients with hypertension and diastolic dysfunction by 46 and 47%, respectively, was found against increased levels of serum tissue inhibitor of metalloproteinase-1 (р=0.049). In patients with diastole dysfunction, myocardial global longitudinal strain was decreased in was observed by 22.8% compared with patients without diastole dysfunction (p <0.05). The analysis revealed a moderate negative relationship between left ventricular global longitudinal strain and the serum levels of metalloproteinases-2 (r=0.64, p <0.05).
Conclusion. In patients with hypertension and left ventricular diastolic dysfunction, a decrease in left ventricular global longitudinal strain is associated with the serum level of matrix metalloproteinase-2; a tissue inhibitor of metalloproteinases-1 is unrelated to left ventricular global myocardial strain.
