Abstract

Magnesium is an essential cation critically involved in cell viability and physiological regulation of all systems and organs. In the cardiovascular system it modulates mechanical, electrical, and structural functions of cardiac and vascular cells, and small changes in extracellular magnesium levels and/or intracellular free magnesium concentration may have profound effects on cardiac excitability, vascular tone, contractility, and reactivity. Magnesium homeostasis is tightly regulated through intestinal absorption and renal excretion and involves specific magnesium transporters, including transient receptor potential melastatin cation channels-6 and -7 and magnesium transporter subtype 1. Perturbations in magnesium metabolism may lead to cellular magnesium deficiency, which has been associated with various pathologies, including cardiovascular disease. This chapter discusses the cellular, physiological, and pharmacological roles of magnesium in the regulation of vascular function and implications of altered magnesium homeostasis in cardiovascular diseases, focusing on hypertension.
