Methods of reducing or preventing intimal damage caused by mechanical stimulation of endothelial cells
Embodiments of the disclosure encompass methods and/or compositions for ameliorating or preventing intimal damage caused by mechanical stimulation of endothelial cells. The damage may be caused by use of a device within an artery, vein, or capillary of an individual, such as to remove a thrombus, an embolus or an atherosclerotic plaque in the vessel. Treatment and prevention embodiments concern therapeutically effective amounts of one or more antagonists of the SUR1-TRPM4 channel that is upregulated upon the mechanical stimulation.
1. A method of inhibiting or reducing intimal damage caused by advance of a catheter through vasculature of a subject in need thereof comprising administering a therapeutically effective amount of glibenclamide or a pharmaceutically acceptable salt thereof to the subject, wherein the administering is solely local administration to increase local concentrations of the glibenclamide or pharmaceutically acceptable salt thereof in a blood vessel undergoing advance of the catheter.
2. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject is during catheter angiography.
3. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject causes endothelial dysfunction in a blood vessel of the subject.
4. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject causes edema in a blood vessel of the subject.
5. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject causes hemorrhage in a blood vessel of the subject.
6. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject causes intimal dissection in arteries of the subject.
7. The method of claim 1 , wherein the advance of a catheter through vasculature of the subject is during a thrombectomy procedure.
8. The method of claim 1 , wherein the subject is undergoing or has undergone a procedure to remove or disrupt a thrombus or embolus or atherosclerotic plaque in a blood vessel.
9. The method of claim 1 , wherein the subject is undergoing or has undergone a endovascular aneurysm repair procedure.
