Animal studies have provided clearcut evidence that sympathetic factors are involved in the
development and maintenance of high blood pressure (BP). This also appears to be the …

Although animal models of hypertension have clearly shown that high blood pressure is
associated with and is probably caused by an increase in sympathetic cardiovascular …

Background Several hemodynamic variables, such as blood pressure, vascular resistance,
cardiac output, and heart rate, are regulated, among others, by sympathetic cardiovascular …

In several experimental animal models of hypertension, sympathetic factors have been
shown to be involved in the development and/or maintenance of high blood pressure …

Animal studies have shown conclusively that sympathetic neural factors are involved in the
development and/or maintenance of high blood pressure. Whether this is also the case for …

Data collected in experimental animals and in humans support the hypothesis that
sympathetic neural mechanisms are involved in the development and progression of …

Despite early demonstrations that sympathetic activation elevates blood pressure and early
clinical inklings that human hypertension may have a psychosomatic component, the pivotal …

Sympathetic neural factors exert a key role in homeostatic blood pressure control. Evidence
is available that abnormalities in sympathetic function may favour the development and …

There are now numerous studies demonstrating that essential hypertension is accompanied
by sympathetic activation. Using drugs which block cardiac sympathetic effects, it could be …

Several experimental evidences have shown that, under standardized conditions, circulating
catecholamines (CA) or norepinephrine (NE) levels can be used as a valid index of the …
