Why the study?
Does plasma noradrenaline correlate with age, sex, or blood pressure in normotensive and hypertensive subjects?
Does plasma noradrenaline correlate with age, sex, or blood pressure in normotensive and hypertensive subjects?
Plasma noradrenaline levels vary by age and sex but do not correlate with supine blood pressure in normotensive or hypertensive individuals.
Answers are grounded in this paper and cite their sources.
Plasma noradrenaline should not guide supine BP assessment; leaves open its age- and sex-specific biomarker utility in prospective studies.
Mean supine plasma noradrenaline was lower in 12 male laboratory staff (0.24 +/- 0.02 microgram/l) than similarly normotensive out-patients (0.44 +/- 0.07 microgram/l). 2. In 164 non-medical hospital staff, plasma noradrenaline increased with age in white males only. 3. Plasma noradrenaline was significantly higher in women than men. 4. There was no relationship between supine blood pressure and plasma noradrenaline in normotensive or hypertensive subjects.
