Why the study?
Does isometric exercise cause a higher pressor response in hypertensive individuals compared to healthy normotensive controls?
Does isometric exercise cause a higher pressor response in hypertensive individuals compared to healthy normotensive controls?
Hypertensive patients exhibit an exaggerated pressor response to isometric exercise that is not blunted by standard antihypertensive therapy, suggesting they should avoid strenuous isometric exercises.
Hypertensives may show exaggerated isometric pressor responses despite therapy; hypothesis-generating for exercise guidance, needs prospective trials.
BackgroundThe purpose of this study was to compare the circulatory responses to isometric exercise in hypertensive individuals with healthy controls in South West Punjab.Aims and objectivesThis study was carried out to examine the pressor response to isometric exercise in hypertensives, and to compare it with the response in healthy individuals.Materials and MethodsThe isometric hand-grip test was employed for this study.ResultsWe found that hypertensives have a higher vascular reactivity to isometric hand-grip test and most of the commonly used anti-hypertensive agents are unable to block this rise.We conclude that hypertensives should avoid strenuous isometric exercises as the steep rise in blood pressure is deleterious to myocardium and cerebral arterioles, which may lead to acute left ventricular failure or cerebrovascular accidents.
