Central systolic blood pressure (cSBP) to brachial systolic blood pressure (brachSBP) ratio reproducibility during antihypertensive therapy

OBJECTIVES Higher CSBP than brachial SBP in individual patient increases cardiovascular (CV) risk. For follow-up it is important to assess the reproducibility of such measurements. The aim this study was these differences, expressed as a CSBP/BrachSBP ratios. SUBJECTS AND METHODS Eighty-three patients on antihypertensive therapy were analysed for ratios after time interval several month up years. estimation, we used Arteriograph (Tensiomed Ltd.), based blood pressure measurements by cuff oscillometric principle, using pulse wave analysis (PWA) assessment CSBP. RESULTS proportion retained same characteristics (either higher central or peripheral SBP) between first and second measurement 71.1 %. association 1st 2nd measurement, statistically significant, p < 0.001. CONCLUSION In our study, high (60 %) treated hypertensive had SBP, which may adversely influence their prognosis. This characteristic highly reproducible. Taking into account differences increase exactness CV risk estimation contribute explanation residual (Tab. 3, Fig. 1, Ref. 28).
