High blood pressure (hypertension) is a chronic disease characterized by a continued rise in numbers of blood pressure in the arteries . Although there is no strict threshold to define the boundary between risk and safety, in accordance with international consensus, a sustained systolic pressure above 139 mm Hg or sustained diastolic pressure greater than 89 mm Hg, are associated with increased measurable risk of atherosclerosis and therefore is considered a clinically significant hypertension. Arterial hypertension, or high blood pressure, characterize by abnormally high pressure of blood against the walls of arteries. (Glasgow, 2002, 155-170)
As hypertension is usually accompany with no symptoms, a significant number of hypertensive patients are unaware of their condition - which is why it is nicknamed the "silent killer". (Dressler, 2001, 608-620)
In my opinion, Hypertension is a public health problem with significant economic and social cost to our country. Its impact on the scope of the insured population seen with increased cardiovascular morbidity and cerebrovascular disease and this led to the formation of the program HTA of that institution.
In my opinion , Hypertension is a morbidity and mortality considerably higher, so it is considered one of the most important public health , especially in developed countries , affecting about one billion people worldwide. Hypertension is an asymptomatic disease and easy to detect, however, presents with severe and lethal complications if not treated early. Chronic hypertension is the single most important modifiable risk for cardiovascular disease and for cerebrovascular disease and renal. (Gerin, 2001, 369-377)
The doctors suggest that, Hypertension, so silent, produces changes in blood flow , at the macro and micro vascular, caused in turn by dysfunction of the inner layer of blood vessels and remodelling of the wall of the arterioles of resistance, which are responsible for maintaining peripheral vascular tone. Many of these changes precede in time the elevation of blood pressure and cause specific organ damage. (Blumenthal, 2002, 569-589)
The nutrition transition and obesity associated with it, appears to play an important role in our series. However, it may also contribute to changes in lifestyle, including less physical activity and increased stress in the population showed a lower Tarata fats and sugars and increased consumption of cereals, tubers, vegetables and fruits, also found greater physical activity and a lower prevalence of hypertension.
An argument for the importance of healthy lifestyles are undoubtedly the information obtained indicates that the higher the body mass index accounted for a greater value of BP which is consistent with other reports in which also mentions a correlation between cardiovascular disease and BMI, diastolic hypertension and BMI. (Sowers, 2001, 379-388)
However, it can be view that, Hypertensive patients who fulfil their treatment are less likely to develop severe hypertension or congestive heart failure . In most cases, the elderly are using lower doses of diuretics as initial antihypertensive therapy. In elderly patients with isolated systolic hypertension is often use as an alternative therapy an inhibitor of calcium channels, long-acting type ...
