36 NORMAL RANGES OF AORTIC PULSE WAVE VELOCITY AND AUGMENTATION INDEX DURING THE MENSTRUAL CYCLE OR ORAL TRIPHASIC CONTRACEPTIVE USE AND REPRODUCIBILITY OF THEIR MEASUREMENT BY APPLANATION TONOMETRY

PurposeArterial stiffness, assessed by aortic pulse wave velocity (aPWV) and augmentation index (AIx), increases in menopause, yet there are no norms for these indices in younger women. This pilot study estimates ranges of aPWV (m/s) and AIx (%) during regular menstrual cycles (MC, 28 [138} 4 days)...

Description
Summary:PurposeArterial stiffness, assessed by aortic pulse wave velocity (aPWV) and augmentation index (AIx), increases in menopause, yet there are no norms for these indices in younger women. This pilot study estimates ranges of aPWV (m/s) and AIx (%) during regular menstrual cycles (MC, 28 [138} 4 days) or triphasic oral contraceptive use (OC).Study DesignWomen 18-45 yrs., BMI = 18.5-26 were studied weekly for 8-16 wk.GroupsMC (n = 16) and OC (n = 7).MethodsNoninvasive applanation tonometry (SphygmoCorTM) supine (position 1) and standing (position 2). Menstrual phase estimated by previous cycle length and first day of menses or 1st day off OC. The distributions of aPWV and AIx in each phase were tested (histogram skewness, kurtosis, Kolmogorov-Smirnoff test)ResultsInter-operator measurements were
