Functional versus structural changes of forearm vascular resistance in hypertension.

Structural changes in resistance vessels have been considered an important factor in triggering and maintaining chronic hypertension in humans and in experimental animals. To determine whether the increased forearm vascular resistance observed following vasodilator maneuvers in hypertensive patients is predominantly due to structural or to functional changes, we examined the influence of differ...

Magnesium and Vascular Changes in Hypertension

Many factors have been implicated in the pathogenesis of hypertension, including changes in intracellular concentrations of calcium, sodium, potassium, and magnesium. There is a significant inverse correlation between serum magnesium and incidence of cardiovascular diseases. Magnesium is a mineral with important functions in the body such as antiarrhythmic effect, actions in vascular tone, cont...

Structural vascular changes in hypertension: role of angiotensin II, dietary sodium supplementation, blood pressure, and time.

The dose and time dependence of angiotensin II (Ang II) induced hypertension and structural vascular changes and the effect of dietary sodium supplementation on these relationships were investigated. Male Sprague-Dawley rats were treated with 50, 100, or 200 ng . kg-1 . min-1 Ang II subcutaneously for 4 or 12 weeks on normal sodium diet (0.7% NaCl) or with 50 ng . kg-1 . min-1 Ang II SC for 12 ...

Relevance of vascular structural and smooth muscle sensitivity changes in hypertension.

This is a mini-review of the vascular changes that occur in experimental hypertension. Augmented vascular resistance and reactivity appear to be due to an increase both in wall thickness and in vascular smooth muscle sensitivity. The increase in wall thickness is an adaptive change that is secondary to the increase in arterial pressure; the altered smooth muscle sensitivity occurs in the absenc...

Localization of vascular resistance changes during hypertension.

Aincrease in the vascular resistance of virtually every organ system is a wellknown characteristic of hypertension, as modeled by spontaneously hypertensive rats (SHR) and renovascular hypertensive rats. However, the most important issue may be where in the macrovasculature and microvasculature of a given organ the greatest increase in resistance occurs. The relevance of this issue can be consi...
