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

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.

Obesity in the postmenopausal period is associated with an increased risk of cardiovascular diseases in women. One of the key drivers of cardiovascular risk is endothelial dysfunction; thus, this is also a crucial point for studies on new therapeutic methods of cardioprotective properties. The aim of the current study was to evaluate the effect of two doses of multispecies probiotic Ecologic® Barrier supplement on functional (primary endpoint) and biochemical parameters (secondary endpoint) of endothelial dysfunction in obese postmenopausal women in a 12-week randomized, placebo-controlled clinical trial. A total of 81 obese Caucasian women participated in the trial. The subjects were randomly assigned to three groups that received a placebo, a low dose (LD) (2.5 × 109 colony forming units (CFU) per day), or a high dose (HD) (1 × 1010 CFU per day) of lyophilisate powder containing live multispecies probiotic bacteria. The probiotic supplement was administered each day for 12 weeks in two equal portions. A high dose probiotic supplementation for 12 weeks decreased systolic blood pressure, vascular endothelial growth factor, pulse wave analysis systolic pressure, pulse wave analysis pulse pressure, pulse wave analysis augmentation index, pulse wave velocity, interleukin-6, tumor necrosis factor alpha, and thrombomodulin. Low doses of probiotic supplementation decreased the systolic blood pressure and interleukin-6 levels. The mean changes in the estimated parameters, compared among the three groups, revealed significant differences in the vascular endothelial growth factor, the pulse wave analysis systolic pressure, the pulse wave analysis augmentation index, the pulse wave velocity, the tumor necrosis factor alpha, and thrombomodulin. The post hoc tests showed significant differences for all parameters between HD and the placebo group, and HD and LD (besides pulse wave analysis augmentation index). We show for the first time that supplementation with multispecies probiotic Ecologic® Barrier favorably modifies both functional and biochemical markers of vascular dysfunction in obese postmenopausal women.

Membrane bioincompatibility was demonstrated by successive white blood cell counts and C3a generation. Pulse wave analysis was obtained by applanation tonometry (SphygmoCor) in a sequential way: basal, after 30 minutes with nul ultrafiltration, and after a complete dialysis with ultrafiltration. At 15 minutes of haemodialysis, significant decrease in leukocyte count occurred: versus (), while C3a levels sharply increased from to  ng/mL (). No changes were observed in augmentation index without ultrafiltration: versus . Only aortic systolic blood pressure was lower at 15 minutes: versus  mmHg (), in agreement with a reduction in brachial systolic blood pressure: versus  mmHg (), without changes in aortic or brachial diastolic blood pressure. Important changes in pulse wave analysis were observed after a complete haemodialysis session: augmentation index versus , aortic systolic blood pressure versus mmHg (), without changes in aortic diastolic blood pressure. In summary, haemodialysis with cellulose diacetate acutely induced a transient state of immunoactivation due to bioincompatibility, this phenomenon was nondetectable by pulse wave analysis. Complete haemodialysis session led to important changes in pulse wave analysis.
