Key result
Higher pulse-wave velocity was an independent predictor of a smaller nocturnal fall in systolic blood pressure (multiple r = 0.272, P < 0.02).
Why the study?
Is arterial distensibility associated with circadian blood pressure variability in untreated patients without cardiovascular complications?
Population
106 patients (69 men, 37 women; aged 20-72 years) without any cardiovascular complication or treatment
Design
Cross-sectional

Hypothesis-generating for arterial stiffness in blunted nocturnal BP dipping; prospective studies needed before clinical consideration.

Is arterial distensibility associated with circadian blood pressure variability in untreated patients without cardiovascular complications?
Effect estimate: multiple r = 0.272
p-value: p=<0.02
Reduced arterial distensibility is associated with increased blood pressure and a blunted nocturnal fall in systolic blood pressure, suggesting its potential utility in risk-stratifying patients.
Roland Asmar (1996) conducted a cross-sectional in Without cardiovascular complication or treatment (n=106). Higher pulse-wave velocity vs. Lower pulse-wave velocity was evaluated on Nocturnal fall in systolic blood pressure (multiple r = 0.272, p=<0.02). Higher pulse-wave velocity was an independent predictor of a smaller nocturnal fall in systolic blood pressure (multiple r = 0.272, P < 0.02).
