title: [Pulse pressure as a prognostic indicator of organ damage in patients with essential hypertension].
abstract: Pulse pressure (PP), defined as systolic blood pressure minus diastolic blood pressure, plays an important role as a risk factor for cardiovascular events. Pulse pressure is pulsatile component of blood pressure. A widened pulse pressure reflects increased stiffness of the large arteries. The aim of the study was to evaluate the association between pulse pressure and organ damage in essential hypertension. We examined 60 subjects, 34 women aged 59 +/- 13 years and 26 men aged 48 +/- 17 years with primary hypertension. In every subject we performed 24-hour automatic blood pressure measurement and echocardiography, abdominal ultrasonography, funduscopy, chest x-ray. We measured sodium potassium, creatinine level in serum and in urine, creatinine clearance and microalbuminuria. Pulse pressure is proportional to the stage of hypertension. A dimension of the aorta parallels with measures of blood pressure. The strong correlation between pulse pressure and damage in funduscopy can indicate, that complication in fundus of the eye are dependent more than the level of a pressure. The significantly higher sodium level in serum and the positive correlation between natremia, natriuresis and pulse pressure proves the role of natrium in pathophysiology of hypertension.
