ABSTRACT
Objective:
To study relationship among ambulatory pulse pressure (PP), pulse pressure index (PPI) and carotid intima-media thickness (IMT) in aged patients with hypertension.Methods:
The 24h ambulatory blood pressures of 159 subjects were measured, and their ambulatory PP [(mean systolic blood pressure (SBP) - mean diastolic blood pressure (DBP)] and ambulatory PPI (ambulatory PP/mean SBP) were calculated. Color Doppler ultrasonography was used to measure carotid IMT. Relationship between ambulatory PPI and carotid IMT was analyzed.Results:
Pearson correlation analysis indicated that carotid IMT was correlated with age (r=0.353), mean SBP (r=0.594), mean DBP (r=-0.355), ambulatory PP (r=0.855) and ambulatory PPI (r=0.883), P<0.001 all. Multivariant gradual regressive analysis indicated that carotid IMT possessed significant linear correlation with ambulatory PP and ambulatory PPI (R2=0.789), and standardized regression coefficient β of ambulatory PPI (β=0.621) was higher than that of ambulatory PP (β=0.284).Conclusion:
Ambulatory pulse pressure index and ambulatory pulse pressure are good indicators for evaluation of carotid arteriosclerosis, and value of ambulatory pulse pressure index is more than.
