Abstract:
A pilot study was conducted to investigate blood pressure level and vasoactive factors (VFs) among age- and sex-matched normotensive (NT), prehypertensive (PH), and hypertensive (EH) subjects. The results showed that angiotensin, arginine vasopressin, and endothelin were significantly higher, while adrenomedullin and calcitonin gene-related peptide were lower in the EH group than in the PH and NT groups. Nitric oxide synthase was not different among the three groups. There was a dose-response relationship between VFs and BP status. The results suggested that changes in blood VFs might be early warning signs of the development of prehypertension to hypertension, and important biomarkers for the early prevention of prehypertension.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
