Key result
Essential hypertension was associated with an amplified increase in vascular resistance following a 50-degree head-up tilt, while heart rate responses were similar to normotensive controls.
Why the study?
Does a 50-degree head-up tilt test elicit different heart rate and vascular resistance responses in men with essential hypertension compared to normotensive controls?
Observational (n=56)
Does a 50-degree head-up tilt test elicit different heart rate and vascular resistance responses in men with essential hypertension compared to normotensive controls?
In essential hypertension, the vascular resistance response to orthostasis is amplified with age and baseline resistance, suggesting structural vascular changes, while heart rate responses remain similar to normotensive individuals.
No takes yet. Share an insight, caveat, or question.
Should not yet alter orthostatic testing protocols; hypothesis-generating for vascular remodeling in hypertension.
London et al. (1987) conducted an observational in Essential hypertension (n=56). Essential hypertension vs. Normotensive controls was evaluated on Changes in hemodynamic parameters (heart rate and vascular resistance) following 50-degree head-up tilt. Essential hypertension was associated with an amplified increase in vascular resistance following a 50-degree head-up tilt, while heart rate responses were similar to normotensive controls.
