Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic thromboembolic pulmonary hypertension is an occlusive disease in pulmonary artery. Only 4% of patients with acute pulmonary embolism develop chronic thromboembolic pulmonary hypertension and acute pulmonary embolism or deep vein thrombosis is reported in the anamnesis of 75% of those with chronic thromboembolic disease. Therefore, the etiology of the disease is not clear. Altought many studies are done, especially the role of inflamation is emhasised underlie the disease.

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.

Matrix metalloprotinase enzymes are known to play a role in atherosclerosis. This research will investigate whether there is atherosclerosis together with inflamattion in the background of chronic thromboembolic hypertension.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PATİENT GROUP(GROUP 1)

This group is the group that underwent pulmonary thromboendarterectomy due to chronic thromboembolic pulmonary hypertension.Sample was taken from the material extracted from this group during operation.

matrix metalloproteinase enzymes 2 and 9

Intervention Type OTHER

concentration of matrix metalloproteinase 2 and 9 enzymes

CONTROL GROUP(GROUP 2)

This group is the group that underwent lobectomy or pneumonectomy for another reason that the pulmonary artery is not affected. Patients operated for a reason other than chronic thromboembolic pulmonary hypertension and samples were taken from the intact pulmonary artery of the removed lung.
