Treatment of Essential Hypertension does not Normalize Capillary Rarefaction
OBJECTIVES To determine if capillary rarefaction persists when hypertension is treated with angiotensin converting enzyme inhibitor, thiazidic diuretic and/or beta-blocker, and to identify which microcirculatory alterations (structural and functional) persist after anti-hypertensive treatment. METHODS We evaluated 28 well-controlled essential hypertensive patients and 19 normotensive subjects...
متن کاملImpaired skin capillary recruitment in essential hypertension is caused by both functional and structural capillary rarefaction.
Capillary rarefaction occurs in many tissues in patients with essential hypertension and may contribute to an increased vascular resistance and impaired muscle metabolism. Rarefaction may be caused by a structural (anatomic) absence of capillaries, functional nonperfusion, or both. The aim of this study was to assess the extent of structural versus functional capillary rarefaction in the skin o...
متن کاملRetinal capillary rarefaction in patients with untreated mild-moderate hypertension
BACKGROUND Microvascular rarefaction influences peripheral vascular resistance, perfusion and metabolism by affecting blood pressure and flow pattern. In hypertension microvascular rarefaction has been described in experimental animal studies as well as in capillaroscopy of skin and biopsies of muscle tissue in patients. Retinal circulation mirrors cerebral microcirculation and allows non-invas...
متن کاملBlunted nocturnal fall in blood pressure and oxidative stress in men and women with essential hypertension.
Low-density lipoprotein oxidation and antioxidant vitamins E and C were investigated in dipper (nocturnal blood pressure fall > 10%) and nondipper (nocturnal blood pressure fall < 10%) hypertensives. We studied 40 dippers and 28 nondippers balanced for gender, age, and body mass index. Blood samples were drawn for lipid profile determination, assessment of thiobarbituric acid-reactive substance...
متن کاملImpaired microvascular dilatation and capillary rarefaction in young adults with a predisposition to high blood pressure.
Increased vascular resistance in essential hypertension occurs mainly in microvessels with luminal diameters < 100 microm. It is not known whether abnormalities in these vessels are a cause or consequence of high blood pressure (BP). We studied 105 men (aged 23-33 yr) in whom predisposition to high blood pressure has been characterized by both their own BP and those of their parents. Factors th...
