Sažetak
Chronic hypertension is a widespread health problem in industrialized countries, with approximately 25% of the adult population affected. The higher the individual's blood pressure, the greater the risk is for developing heart disease, stroke, renal failure, and peripheral vascular disease. Other factors such as cigarette smoking and hyperlipidemia increase the risk for hypertension&#8211; associated complication. The World Health Organization guidelines have defined the criteria for hypertension. These have been subdivided into several categories. Healthy categories include optimal (120/80), normal (<130/85), and high normal (130 to 139/85 to 89). It is important not to make diagnosis of hypertension on the basis of a single measurement, because the stress of visiting a physician may be sufficient to elevate blood pressure in some patients. The two broad categories in hypertension are primary (essential), and secondary hypertension. The cause of primary hypertension is unknown, and it is improbable that there is a single cause to explain the diversity of hemodynamic pathophysiological derangement in this condition. Unknown genetic and environmental factors may play a role in the approximately 95% of patients with essential or primary hypertension. Definable or secondary causes such as renal vascular disease, chronic renal failure, and endocrine abnormalities are uncommon and account for 5% to 10% of cases at most. It is important to recognize hypertension, because it is treatable, and treatment reduces the incidence of complications. This may save the hypertensive patients from life-long expensive medical therapy ; the extent of medical therapy may itself be associated with complication. Once hypertension has been identified in a patient through multiple determinations of blood pressure, a laboratory evaluation should be initiated. This evaluation serves three main purposes: &#8226; to exclude treatable causes of secondary hypertension, &#8226; to detect evidence of organ damage, &#8226; to identify other risk factors that may accelerate cardiovascular disease, &#8226; to monitor the biochemical effects of therapy.
