Arterial stiffness potently predicts mortality in dialysis patients. Pulse-wave analysis permits the non-invasive assessment of indices of arterial stiffness and the central pressure waveform by applanation tonometry. The aim of this study was to assess the reproducibility of pulse-wave analysis in patients with chronic renal failure. A total of 188 subjects (23 healthy controls, along with 71 pre-dialysis, 67 dialysis and 27 transplant patients) took part. Duplicate measurements were recorded of brachial blood pressure using the semi-automated Omron 705 device and of the radial artery pressure waveform using applanation tonometry. The central pressure aortic waveform was then obtained by application of a transfer function incorporated into the SphygmoCor software. Central aortic mean blood pressure (MBP), indices of arterial stiffness [augmentation index (AIx) and time to reflection (TR)] and the subendocardial viability ratio (SEVR) were analysed for intra-observer, inter-observer and long-term reproducibility using Bland-Altman plots. The mean (±S.D.) intra-observer difference was 0±4% for AIx, 0±20 ms for TR, 0±3 mmHg for aortic MBP and 0±18% for the SEVR. Inter-observer mean differences were 0±3% for AIx, 1±7ms for TR, 1±4mmHg for aortic MBP and 1±9% for the SEVR. For the long-term study, the mean differences were -1±9% for AIx, -2±13mmHg for aortic MBP, -2±12ms for TR and 1±29% for the SEVR. Pulse-wave analysis showed excellent reproducibility in all the studies, and is therefore suitable for use in all patients with chronic renal failure. Further prospective and interventional studies are now required to assess whether AIx and TR are important prognostic indices of cardiovascular events, and therefore relevant surrogate indices of arterial stiffness in this susceptible population.

The aim of our study was to investigate the association between pulse wave velocity (PWV) and pulse wave analysis (PWA)-derived measurements for the evaluation of arterial stiffness. A total of 20 (7 male and 13 female) healthy, non-smoking individuals, with mean age 31 ± 12years were included. PWV and PWA measurements were performed using a SphygmoCor apparatus (Atcor Medical Blood Pressure Analysis System, Sydney Australia). PWV significantly correlated with all central aortic haemodynamic parameters, especially with pulse pressure (PP) (p < 0.0001), augmentation index corrected for 75 pulses/min (AI75) (p = 0.035) and augmentation pressure (AP) (p = 0.005). Male subjects presented significantly higher PWV compared with females (p = 0.03), while there were no differences in PP, AP and AI75. In conclusion, PWA is strongly correlated with PWV as a method for the evaluation of arterial stiffness.

Introduction: Arterial stiffness is recognised as a significant cardiovascular risk factor and an independent predictor of all causes of cardiovascular death. Women are the largest population exposed to cigarette smoke either at work or from their partner. The objectives of this study are to compare the arterial stiffness (augmentation index and pulse wave velocity) between second hand smoke (SHS) and non second hand smoke (non-SHS). Designs and method: Comparative cross-sectional study was conducted among 118 healthy female subjects (64 SHS and 54 non- SHS). The women were in the SHS group if their spouse is a smoker and they had an exposure to cigarette smoke for at least three years, minimum of15 minutes two days a week. Pulse wave analysis and pulse wave velocity was used to study the arterial stiffness. Pulse wave analysis reported as percentage of augmentation index. Pulse wave velocity equal to carotid femoral distance (meter) divided by time (second) Results: The mean augmentation index (AIx) for SHS groups was 17.9 (SD7.06) and for non SHS groups was 20.7(SD6.11). The mean of Pulse wave velocity was 8.94 (SD1.36) in SHS groups and 9.02 (SD8.68) in non SHS groups. ANOVA and ANCOVA shown significance difference in crude mean (p = 0.047) and estimated marginal mean (p = 0.028) of augmentation index between SHS and non - SHS after controlling for age and BMI. However, there was no significant difference in crude mean (p = 0.795) and estimated marginal mean (p = 0.716) pulse wave velocity between SHS and non - SHS after controlling for age and BMI. Conclusion: An increase in augmentation index amongst non SHS in this study most probably due to exposure to environmental tobacco at work compared to exposure to spouse’s smoke Bangladesh Journal of Medical Science Vol.18(2) 2019 p.340-346
