Oxidative stress initiates hemodynamic change in CKD-induced heart disease.

ABSTRACT: Chronic kidney disease (CKD) predisposes to cardiac remodeling and coronary microvascular dysfunction. Studies in swine identified changes in microvascular structure and function, as well as changes in mitochondrial structure and oxidative stress. However, CKD was combined with metabolic derangement, thereby obscuring the contribution of CKD alone. Therefore, we studied the impact of CKD on the heart and combined proteome studies with measurement of cardiac function and perfusion to identify processes involved in cardiac remodeling in CKD. CKD was induced in swine at 10-12 weeks of age while sham-operated swine served as controls. 5-6 months later, left ventricular (LV) function and coronary flow reserve were measured. LC-MS-MS-based proteomic analysis of LV tissue was performed. LV myocar
