Primary outcomePrimary: Concentration of Matrix Metalloproteinase 2 and 9 Enzymes — 89289.89; 86548.72; 205707.83; 152911.57 ng/ml — p=<0.05
Summary
Chronic thromboembolic pulmonary hypertension is an occlusive disease in pulmonary artery.Matrix metalloproteinase enzymes play a substantial role of extracellular matrix remodeling. The clot formed in chronic thromboembolic pulmonary hypertension does not melt and turns into a fibrous state, it occludes the pulmonary artery.In this study, investigators aimed to investigate the role of matrix metalloproteinase enzymes in pulmonary arterial wall remodeling in patients with chronic thromboembolic pulmonary hypertension
