BACKGROUND AND AIMS: Erythropoietin (EPO) stimulates erythropoiesis through its specific receptor (EPO-R). Preclinical work has assigned a role for the EPO/EPO-R system in the heart and blood vessels. The potential use of erythropoiesis-stimulating agents (ESAs) for nonhematopoietic indications is a focus of current research. This article considers proven actions of ...

Hypertension is a common disorder linked to increases in cardiovascular mortality and morbidity. Effective treatment decreases this excess mortality. Therapy with a single antihypertensive agent fails to achieve blood pressure goals in up to 75 % of patients. Compared to monotherapy, combination antihypertensive therapy, especially with fixed-dose (single pill) formulations, may ...

Abstract There is overwhelming evidence that a reduction in salt intake from the current level of approximately 9-12 g/d in most countries of the world to the recommended level of 5-6 g/d lowers blood pressure (BP) in both hypertensive and normotensive individuals. A further reduction to 3-4 g/d has a ...
