Why the study?
Is blood pressure variability related to sympathetic nervous system activity in patients with untreated essential hypertension?
Is blood pressure variability related to sympathetic nervous system activity in patients with untreated essential hypertension?
Blood pressure variability in untreated essential hypertension appears to be driven by the absolute level of blood pressure and age rather than sympathetic nervous system overactivity.
No takes yet. Share an insight, caveat, or question.
BP variability tied to mean level and age, not sympathetic markers, in untreated hypertension; leaves open SNS contribution pending longitudinal data.
Clément et al. (1979) studied this question.
