Figure 2.
A proposed schematic overview of the pathological mechanisms that underlie the progression of CKD to HFpEF. Blue box depicts renal factors; green box depicts coronary microvascular factors; and red box depicts myocardial changes contributing to HFpEF. AGEs, advanced glycation products; CKD, chronic kidney disease; EC, endothelial cell; FGF-23, fibroblast growth factor 23; HFpEF, heart failure with preserved ejection fraction; LV, left ventricle; NO, nitric oxide; RAAS, renin-angiotensin-aldosterone system; ROS, reactive oxygen species; VSMC, vascular smooth muscle cell.
