Implication
Baroreflex sensitivity should not inform blood pressure assessment beyond age; leaves open independent prognostic value in longitudinal studies.
Structured PICO
P
Population
48 untreated subjects, mean age 43 (range 20-71) years, with blood pressures ranging from 104 to 202 mmHg systolic and 52 to 120 mmHg diastolic.
I
Intervention
Measurement of carotid baroreceptor-heart rate sensitivity using a modified non-invasive neck-chamber method.
O
Outcome
Carotid baroreflex sensitivity and its relationship with age and blood pressure.surrogate
Carotid baroreflex sensitivity declines with age, but is not independently associated with blood pressure when accounting for age.
