Additionally, in the diabetic AS cohort, there was an increase in oxidative stress markers (hydrogen peroxide (H2O2), 3-nitrotyrosine, lipid peroxidation (LPO), oxidative glutathione (GSSG)/reduced glutathione (GSH) ratio) within the myocardium and mitochondria, accompanied by impaired NO-sGC-cGMP-PKG signaling, decreased titin phosphorylation, and increased passive stiffness (Fpassive) of cardiomyocytes relative to non-diabetic AS patients. The gene discussed is SGCB; the disease is aortic stenosis.
