Mechanism of a hypertensive response to exercise.
Mottram et al. (1) recently reported in the Journal new and unexpected findings: that a hypertensive response to exercise (systolic blood pressure 210 mm Hg in males and 190 mm Hg in females) in normotensive and hypertensive subjects is associated with subtle defects in systolic left ventricular (LV) function. A number of possible mechanisms were proposed. Another explanation, not canvassed, re...
متن کاملHypertensive response to exercise: mechanisms and clinical implication
A hypertensive response to exercise (HRE) is frequently observed in individuals without hypertension or other cardiovascular disease. However, mechanisms and clinical implication of HRE is not fully elucidated. Endothelial dysfunction and increased stiffness of large artery contribute to development of HRE. From neurohormonal aspects, excess stimulation of sympathetic nervous system and augment...
متن کاملCardiovascular response to isometric exercise in normal adolescents.
The purpose of this study was to document the cardiovascular response to submaximal isometric handgrip (IHG) exercise in 32 normal adolescents. Left ventricular (LV) dimensions and systolic time intervals were recorded using echocardiography; blood pressure was measured by sphygmomanometry both at rest and during IHG exercise at 25% maximum contraction. This level of isometric exercise produced...
متن کاملLosartan improves exercise tolerance in patients with diastolic dysfunction and a hypertensive response to exercise.
OBJECTIVES The aim of the study was to test the hypothesis that angiotensin II (Ang II) blockade would improve exercise tolerance in patients with diastolic dysfunction and a marked increase in systolic blood pressure (SBP) during exercise. BACKGROUND Diastolic dysfunction may be exacerbated during exercise, especially if there is a marked increase in SBP. Angiotensin II may contribute to the...
متن کاملCardiopulmonary Exercise Test in Patients with Hypertension: Focused on Hypertensive Response to Exercise.
The cardiopulmonary exercise test (CPET) provides integrative exercise responses including the cardiovascular, pulmonary and skeletal muscle systems. It can be used for the identification of myocardial ischemia, evaluation of exercise capacity and tolerance, and the assessment of chronotropic competence or arrhythmias with the addition of ventilatory and gas exchange measurement information. Am...
