Implication

May indicate early autonomic shifts in borderline hypertension; leaves open whether spectral analysis aids risk stratification.

Structured PICO

Does short-term variability of blood pressure and heart rate differ between normotensive, borderline hypertensive, and mildly hypertensive men?

P
Population
96 men (aged 35 to 45 years), including 33 normotensive, 29 borderline hypertensive, and 34 mildly hypertensive individuals.
I
Intervention
Intra-arterial blood pressure and electrocardiogram recording over a 30-hour period (Oxford method) with frequency domain analysis.
C
Comparator
Normotensive individuals.
O
Outcome
Power spectrum density estimates of systolic blood pressure, diastolic blood pressure, and heart rate over low-frequency (0.02-0.075 Hz), midfrequency (0.075-0.15 Hz), and high-frequency (0.15-0.35 Hz) bandwidths.surrogate

Spectral analysis of blood pressure variability reveals that borderline hypertensive individuals exhibit altered baroreceptor oscillations shifted to lower frequencies, suggesting altered sympathetic nervous system function.
