Abstract

BACKGROUND
Previous studies showed that great difference of inter-arm blood pressure (IABP) was associated with adverse cardiovascular outcomes. However, these studies had measurement bias because blood pressure (BP) was measured sequentially for each arm. Then, the aim of present study, using simultaneous BP measurement, is to investigate the association between ankle brachial index (ABI), brachial ankle pulse wave velocity (baPWV) and IABP difference in patients without cardiovascular disease.
METHODS
We conducted cross sectional study from medical data and selected 153 (116 men, 37 women) patients aged 18 years or older. Simultaneous BP measurements were recorded using automatic oscillometric monitor equipped with dual arm cuffs in both arms. At the same day, ABI, baPWV, and physical parameters were evaluated.
RESULTS
The mean age of the subjects was 52.8 +/- 9.9 and the difference of inter-arm systolic BP (SBP) and diastolic BP (DBP) were 5.6 +/- 4.3 and 4.5 +/- 3.7 mm Hg. Compared with group with an inter-arm SBP difference less than 5 mm Hg, group with an inter-arm SBP difference more than 5 mm Hg was more older (p = 0.012), more higher proportion of patient whose left arm SBP was higher than right (p = 0.004), higher left arm SBP (p = 0.044) and higher baPWV (p = 0.025). However, the difference of IABP in SBP and DBP had no significant correlation with the age (r = 0.152, p = 0.06 and r = 0.03, p = 0.715), ABI (r = 0.021, p = 0.801 and r = 0.131, p = 0.105) and baPWV (r = 0.115, p = 0.158 and r = 0.068, p = 0.403).
CONCLUSIONS
There were no significant correlation between the differences of IABP in simultaneous BP measurements and ABI, baPWV.
