“…As our second objective was correlation between RI and SI, which is found to be significant. Study performed by Brilliante et al, showed a significant correlation of RI and SI with age, heart rate, systolic blood pressure and diastolic blood pressure [21].…”

Introduction: Arterial compliance will result in stabilizing the fluctuations in arterial pressure and blood flow. So arterial stiffness can be a good indicator for monitoring the cardiovascular system. Arterial stiffness can be measured using indices like reflection index (RI), stiffness index (SI) and Brachial Finger Pulse Wave Velocity (BFPWV).Objectives: Aim of our study was to evaluate the changes in RI, SI and BFPWV during different phases of the menstrual cycle and to correlate RI with SI in healthy female subjects between the age group of 18-30 years from Bangalore, India. Materials and Methods:Basal recordings of RI and SI were determined by Photo Pulse Plethysmography (PPG) picked up from the fingertip using BIOPAC system and BFPWV was obtained using Doppler. Recordings were obtained at three different time points during the menstrual cycle. Analysis was done using repeated measures ANOVA with Bonferroni correction.Result: There was a significant decrease in above parameters p<0.05 during the mid-cycle. Correlation between RI and SI was also significant p<0.05. Conclusion:These findings suggests that the menstrual cycle affects the arterial stiffness and one of the factor is oestrogen. Hence, women are less prone to the incidence of cardiovascular diseases before menopause. Screening for arterial stiffness in a general population, using these indices is valid, economical and reliable.

“…The present study agrees with findings on BP in another study. 41 RI at rest reflects the current state of arterial tone, 16,17 and a lower RI is an indicator of more relaxed arteries. Also FST reflects blood flow 42, 43 and is regulated by sympathetic tone, 44 which relates FST to RI and endothelial function, 45 but not to SI.…”

“…Among the young population, lack of health screening may also predispose to increase CVD prevalence finger arterial bed and is influenced by several factors such as ventricular ejection, aortic and peripheral arterial stiffness (AS), peripheral arterial resistance and blood viscosity (Elgendi 2012;Millasseau et al 2002). Several common parameters that were derived from finger PPG are stiffness index (SI), reflection index (RI), crest time and a, b, c, d and e waves, and all were proposed to be indices of vascular function and vascular ageing (Millasseau et al 2002;Brillante et al 2008;Baek et al 2007;Hashimoto et al 2005;Takazawa et al 1998;Tsai et al 2007).…”

ABSTRAK Dua petanda kesihatan salur darah baru yang dihasilkan daripada gelombang fotopletismografi jari (PPG) telah diperkenalkan berdasarkan populasi rakyat Malaysia iaitu indeks kecergasan PPG (PPGF) dan indeks jangkaan risiko salur darah (VRPI). Antara objektif kajian ini adalah untuk mengkaji hubungan antara PPGF dengan petanda penyakit jantung (CVD (Beta = 0.35, p < 0.01), p < 0.01), p = 0.04) dan ketinggian (Beta = 0.24, p < 0.01 ABSTRACTTwo new vascular health markers which are derived from finger photoplethysmography (PPG) waveform have been introduced based on Malaysian population, namely PPG fitness index (PPGF) and vascular risk prediction index (VRPI). The objectives of this study were to investigate the associations between PPGF and other cardiovascular disease (CVD) markers such as carotid femoral pulse wave velocity (PWV CF ), to compare PPGF between those with and without CVD risk factors and to determine the sensitivity of VRPI in identifying young subjects with CVD risk factors. A total of 114 men age 20 to 40 yrs with and without CVD risk factors were recruited. Risk factors included hypertension, smoking, dyslipidemia, abdominal obesity and family history of premature CVD. Subjects were divided into healthy, those with one risk factor and those with at least two risk factors. Their weight, height, peripheral and central blood pressure (BP), PWV CF and PPGF were measured and the sensitivity of VRPI in predicting subjects with CVD risk factor was calculated. Data was analyzed via SPSS version 15 and p < 0.05 was considered significant. The mean age of the subjects was 28.94 ± 4.86 yrs. No differences in PPGF was observed between groups (p > 0.05). The independent variables for PPGF were forward pressure (Beta = 0.35, p < 0.01), PWV CF (Beta = -0.26, p < 0.01), systolic BP (Beta = -0.26, p = 0.04) and height (Beta = 0.24, p < 0.01). The sensitivity of VRPI was 82.02%. In conclusion, PPGF was correlated to PWV CF and may be a potential marker of arterial stiffness. In addition, VRPI is sensitive to be used as an early screening of CVD risk factors.

Arterial stiffness indices in healthy volunteers using non‐invasive digital photoplethysmography

Abstract: Digital photoplethysmography is a portable, operator-independent, reproducible and simple method of measuring arterial stiffness. Ranges of normality of arterial stiffness will depend on the individual's age, race, lipid levels, HR and blood pressure.
