Endothelial dysfunction and chronic kidney disease: treatment options

Current Opinion in Investigational Drugs
J Ruth Wu-Wong

Abstract

Endothelial cells detect physical and chemical changes in the blood vessels, and release various factors to counter these changes to maintain homeostasis. Traditional cardiovascular disease risk factors, such as hypertension, dyslipidemia and diabetes, cause endothelial dysfunction characterized by off-balanced vasodilation/vasoconstriction, increased oxidative stress and inflammation, deregulation of thrombosis and fibrinolysis, abnormal smooth muscle cell proliferation, and a deficient repair mechanism. Patients with chronic kidney disease (CKD) have a much higher risk of cardiovascular disease and mortality than the general population. Endothelial dysfunction is commonly observed in CKD, likely preceding other cardiovascular complications. Lipid-lowering agents, such as statins, improve endothelial functions and are effective in reducing cardiovascular disease risk in the general population, but have not demonstrated comparable efficacy in the CKD patient population. Similarly, antidiabetic agents, such as thiazolidinediones, that improve endothelial function in the general population are less efficacious than expected in slowing disease progression and reducing cardiovascular disease risk in CKD patients. Interestingly, age...Continue Reading

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
