Abstract
Both endothelin(ET)-1 and oxidative stress have been the subjects of intense investigation within the cardiovascular field over the past decade and a half, yet little is known about the precise relationship between these important modulators of vascular function. There is a firm evidence that ET-1 can stimulate the production of superoxide via NADPH oxidase activation, and at the same time, reactive oxygen species appear to stimulate ET-1 production. What is less clear is how these changes participate in the pathogenesis of vascular dysfunction. There is mixed evidence on whether oxidative stress plays a role in ET-dependent hypertension, however, a specific influence of ET-induced oxidative stress to reduce vascular reactivity is more convincing. The current review summarizes recent investigations into the relationship between ET-1 and oxidative stress and highlights several areas that require further investigation.

Ischemic Cardiovascular Diseases: Mechanisms, Diagnosis and Therapy
Ischemic cardiovascular disease includes myocardial infarction, coronary atherosclerotic heart disease, angina pectoris, etc., constitute the leading cause of patient mortality by preventing tissues from getting sufficient oxygen and nutrients. Ischemic heart disease, as a clinical condition, is characterized by myocardial ischemia, causing an imbalance between myocardial blood supply and demand, ...read more
TREATMENT OF CARDIOVASCULAR DISEASE IN CHRONIC AND END STAGE KIDNEY DISEASE
Cardiovascular disease still remains the leading cause of death in Chronic and End Stage Kidney Disease, accounting for more than half of all deaths in dialysis patients. During the past decade, research has been focused on novel therapeutic agents that might delay or even reverse cardiovascular disease and vascular calcification, ...read more
