Hypothesis: PWV don’t correlate with age in the upper limb but in the aorta and lower limb.
Aim: To study the relationship between ageing and indices based on pulse wave transit time (PWTT) between the toe and the finger.
Material and methods: measurements were performed in 300 patients in primary care and occupational practice, after 5 minutes of supine rest using a new device (pOpmètre® - Axelife SAS - France) which measures the toe and finger PWTT relative to R-ECG wave. Difference of PWTT between the toe and finger (DTF) was computed and, using a chart based on body height, we calculated the PWVtf [PWVtf = k *subject’s height / DTF] and the pOpscore® (toePWV / fingerPWV) indices.
Results: Of the tested 300 patients, 147 (93 men and 54 women aged 45yrs ± 2 vs. 40yrs ± 2, p=0.048 respectively) with 0 or only 1 conventional risk factor and without known POAD or Vasodilator therapy.
Sex anova (F; p) | Age (years) (r2; p) | Weight (Kg) (r2; p) | Height (cm) (r2; p) | SBP (mmHg) (r2; p) | DBP (mmHg) (r2; p) | MBP (mmHg) (r2; p) | BMI (Kg/m2) (r2; p) | |
---|---|---|---|---|---|---|---|---|
DTF (sec) | 0.01;ns | 0.69;10−4 | 0.001;ns | 0.02;0.08 | 0.29;10−4 | 0.07;10−3 | 0.18; 10−4 | 0.04;0.01 |
PWVtf (m/s) | 0.10;ns | 0.69;10−4 | 0.003;ns | 0.01;ns | 0.22;10−4 | 0.03;0.02 | 0.12; 10−4 | 0.014; ns |
pOpscore® | 0.04;ns | 0.60;10−4 | 0.008;ns | 0.01;ns | 0.23;10−4 | 0.07;10−3 | 0.15; 10−4 | 0.02;0.04 |
Using stepwise regression analysis, (variables to enter: Age, BMI, SBP, DBP, MBP), 1) DTF was dependent with age (p <0.0001) and SBP (p <0.01); 2) PWVtf with age (p <0.0001), SBP (p <0.01) and DBP (p <0.05); 3) pOpscore® was dependent only with age (p <0.0001) not with SBP (p > 0.07).
Conclusion: In this study,
- 1-
All variables were correlated to age and blood pressure.
- 2-
pOpscore® is related only to ageing independently from blood pressure.
- 3-
pOpmètre® is a promising technique for the routine determination of vascular ageing in primary care medicine.
