Clinical Trial Summary

To investigate the relationship betweeen plasma S-adenosylhomocysteine (SAH) levels and endothelial dysfunction, we plan to enroll approximately 150 patients with high risk of cardiovascualr disease,who will be measaured the flow-mediated dilation by B-ultrasound, and then measaured the plasma levels of methionine metabolites, such as SAH, SAM, and analyze the association.


Clinical Trial Description

To investigate the relationship betweeen plasma S-adenosylhomocysteine (SAH) levels and endothelial dysfunction, we plan to enroll approximately 150 patients with high risk of cardiovascualr disease,who will be measaured the flow-mediated dilation by B-ultrasound, and then use HPLC-MS/MS to measaure the plasma levels of methionine metabolites, such as SAH, SAM, and use methylated specifical PCR to detect the promoter DNA methylation of p66shc, and use ELISA kits to measure the plasma ROS levels of CVD patients, such as MDA, 8-iso-prostaglandin F2a, and finally analyze the association between SAH, ROS levels, promoter DNA methylation of p66shc, and flow-mediated dilation. ;
