L-Arginine pour Endothelial Dysfunction

C Preuves Preuves limitées issues de petites études, mais certains signaux positifs existent.

Research suggests improvement in FMD and blood pressure. However, the VINTAGE MI trial showed potential harm in acute MI patients. Generally considered safe in stable patients, but should be avoided post-MI.
