Brief Summary:
In Colombia, ischemic heart disease and stroke are one of the most important causes of death in 45 years old people. Care of cases of disease represents high costs for the health system in particular and society in general, due to the loss of productive years life and costs for the care of the aftermath. Hypertension (HT) is one of the preventable risk factors for major cerebrovascular disorders. The pathophysiology of Essential hypertension is complex and depends of interaction of genetic and environmental factors. Among the determining elements are the increase in the activity of the sympathetic nervous system, the vasoconstricting and overproduction of hormones associated with sodium retention, disruption in renin secretion with increased production of aldosterone and angiotensin II, the deregulation of the kinins system, the increase in peripheral vascular resistance and activity of Growth factors in atherogenesis and vascular endothelial dysfunction, increased cardiac output, diabetes mellitus, obesity, and lower production of vasodilators such as brain natriuretic peptide (BNP), the prostacyclins and nitric oxide (NO), among others.
Cocoa is a food rich in flavonoids, which stimulate the enzyme activity of endothelial nitric oxide synthase (e-NOS), responsible of the production of NO in vascular smooth muscle. The flavonoids modulate the synthesis of inflammatory substances that are derived from endothelial cells and the immune system.
In a recent study found that with a few grams of cocoa achieves a significant reduction in blood pressure, so the investigators propose a controlled clinical trial to assess the effect of different doses of cocoa on blood pressure and endothelial inflammation in men with essential hypertension, stage I-II without target organ damage, in addition to pharmacologic monotherapy defined for the management of their disease. The investigators hope to determine an optimal dose of cocoa, with long-term effects, by their high content of flavonoids, improves cardiovascular and endothelial parameters with the advantage that it is an economical and easy introduction into the patient's habits.
