Systemic arterial hypertension (SAH) is one of the most common conditions seen in primary care of cardiovascular disease and whose consequences; depending on the "target organ" affecting produce ischemic heart disease, cerebral vascular disease or chronic kidney disease. In the pathogenesis of HAS are several physiopathological mechanisms involved; of which currently, to name the most important and frequent play a role in increasing adrenaline levels, the renin-angiotensin-aldosterone system and recently, much the participation of insulin resistance and hyperinsulinemia mentioned. These processes lead to an imbalance between the sympathetic and parasympathetic tone, coupled with hypersensitivity sodium trigger one of the pathophysiologic mechanisms of hypertension.
