Abstract

Background: Recently, prof Anatoly N Rogoza proposed a new vascular index calculated from one-channel volume sphygmography of brachial artery, Rogoza’s Index or Rogoza Index. It may be useful as a new indicator of asymptomatic vascular damage associated with cardiovascular risk in patients with hypertension.

Objective: This study provides just an idea about the Rogoza Index in healthy volunteers as a function of age and sex.

Methods: The object of the study was the set of 120 bpw-files (BPLab format) with oscillometric ambulatory (24-h) blood pressure readings in age-matched group of 60 male and 60 female healthy volunteers. Rogoza Index (ms/cm) was calculated as RWTT/L where RWTT is reflected wave transit time (ms) and L is height (cm).

Results: Averaged 24-h Rogoza Index was 1.1885–0.0063·Age (r=−0.30) for men and 0.93276–0.0025·Age (r=−0.27) for women; averaged daytime Rogoza Index was 1.2054–0.0067·Age (r=−0.32) and 0.90598–0.0022·Age (r=−0.22) and nightime 1.1412–0.0049·Age (r=−0.24) and 1.0076–0.0033·Age (r=−0.31) accordingly. All correlations are significant, p<0.05.

There was also a significant difference between Rogoza Indices in male and female subgroups: for 24-h period Rogoza Index was of 0.88 vs 0.80 ms/cm (mean, p=0.002); for daytime of 0.79 vs 0.87 ms/cm (p=0.001); and for nighttime of 0.84 vs 0.90 ms/cm (p=0.002).

Conclusions: Rogoza Index is sex- and age- dependent like other surrogate indices of arterial stiffness.
