Introduction
Structural, humoral and neuronal factors are involved in cardiovascular regulation. The reninangiotensinaldosterone system (RAAS) plays a central role in cardiovascular regulation as both a circulating hormone and a paracrine mediator. The endothelium is a source of paracrine mediators such as nitric oxide (NO), endothelial-derived hyperpolarizing factor (EDHF) and endothelin (Figure 1
). These circulating and local regulatory systems exhibit complex synergisms and interactions; the sympathetic nervous system stimulates secretion of rennin and angiotensin II which, centrally and at the presynaptic level, increase sympathetic nerve activity and enhance endothelin and vasopressin production. Atrial natriuretic peptides on the other hand counteract the RAAS and endothelin. Endothelial substances act primarily locally and exhibit vasoconstrictor, vasodilating, and mitogenic effects. All these regulatory systems are responsible for proper circulatory homeostasis and for structural vascular and myocardial regulation.
