Static exercise in untreated systemic hypertension.

The circulatory responses to sustained handgrip at 30 per cent of a maximum voluntary contraction of the forearm muscles (MVC) were examined in untreated hypertensive patients. Arterial pressure increased in all patients, often attaining very high levels. Two main patterns of circulatory response were observed. In group i (8 patients) there was an increase in cardiac index and heart rate, with ...

Determinants of exercise-induced pulmonary arterial hypertension in systemic sclerosis.

BACKGROUND Exercise-induced pulmonary arterial hypertension (EIPH) in systemic sclerosis (SSc) has already been observed but its determinants remain unclear. The aim of this study was to determine the incidence and the determinants of EIPH in SSc. METHODS AND RESULTS We prospectively enrolled 63 patients with SSc (age 54±3years, 76% female) followed in CHU Sart-Tilman in Liège. All patients u...

Aftereffects of exercise on regional and systemic hemodynamics in hypertension.

Several studies have indicated that a single bout of physical exercise induced a significant antihypertensive effect during the hours after the activity. However, little information is presently available on the underlying hemodynamic changes. We examined 13 essential hypertensive patients and nine normotensive subjects in a randomized, crossover study design during 3 hours after a 30-minute pe...

Effects of Physical Activity and Aerobic Exercise Capacity on Aortic Stiffness in Patients With Untreated Hypertension

Background and Objectives: High aerobic exercise capacity and sport-related physical activity are reported to be inversely associated with arterial stiffness in healthy young adults. However, it is unknown whether increased physical activity and/or high aerobic exercise capacity attenuate arterial stiffness in patients with untreated hypertension. Subjects and Methods: We studied subjects with ...

Static Exercise in Humans

Although previous studies in both animals and humans have suggested that cardiac baroreceptors modulate reflex sympathetic vasoconstriction during exercise, more recent studies in conscious animals have not supported this view. To further test this concept in humans, we measured sympathetic nerve discharge with intraneural microelectrodes while we used static handgrip to activate the exercise p...
