Matrix Metalloproteinases/Tissue Inhibitors of Metalloproteinases

Abstract

Patients with hypertension but normal LV structure and function had normal MMP/TIMP profiles. Changes in MMP profiles that favor decreased ECM degradation were associated with LVH and diastolic dysfunction. An increased TIMP-1 level predicted the presence of CHF. Although these findings should be confirmed in a larger prospective study, these data do suggest that changes in the MMP/TIMP balance may play an important role in the structural, functional, and clinical manifestations of hypertensive heart disease.
