Why the study?
How do RR interval, blood pressure variability, and humoral factors change during postural changes in patients with borderline arterial hypertension compared to normotensive controls?
Population
67 subjects, comprising 29 patients with borderline arterial hypertension and 38 normotensive controls.
Comparison
Postural changes (supine to standing position) vs Normotensive control group undergoing the same…

May link renin to autonomic shifts in borderline hypertension; hypothesis-generating, requires prospective validation before clinical use.
How do RR interval, blood pressure variability, and humoral factors change during postural changes in patients with borderline arterial hypertension compared to normotensive controls?
Borderline arterial hypertension is associated with increased low- and high-frequency oscillations of blood pressure at rest, and renin release during postural changes correlates with autonomic nervous system alterations.
Duprez et al. (1995) studied this question.
