“…To date, a fairly large number of advanced PWV measurement technologies have been developed (Jiang et al 2008, Nabeel et al 2017a, 2017b, Benas et al 2019, Milan et al 2019, Salvi et al 2019, Lundström et al 2022. However, the arterial network within which PWV is identified and analyzed is usually heterogeneous.…”

Objective. Pulse wave velocity (PWV) is a key diagnostic parameter of the cardiovascular system state. However, the approaches aimed at the PWV characterization often suffer from inevitable drawbacks. The statistical results demonstrating how closely the PWV in the radial artery (RA) and the respiration phase correlate, as well as the RA PWV evolution during breath-holding (BH), have not been presented in the literature yet. The aims of this study are: a) to propose a simple robust technique for measuring RA PWV, b) to reveal the phase relation between the RA PWV and spontaneous breathing, c) to disclose the BH influence on the RA PWV. Approach. The high-resolution remote breathing monitoring method, Sorption-Enhanced Infrared Thermography (SEIRT), and the described new technique aimed at measuring RA PWV, were used synchronously, and their measurement data were processed simultaneously. Main Results. Spontaneous breathing leaves a synchronous "trace" on the RA PWV. The close linear correlation of the respiration phase and the phase of concomitant RA PWV changes is statistically confirmed in 5 tested persons (Pearson's r is of the order of 0.5-0.8, P<0.05). The BH appreciably affects the RA PWV. A phenomenon showing that the RA PWV is not indifferent to hypoxia is observed for the first time. Significance. The proposed technique for the RA PWV characterization has high prospects in biomedical diagnostics. The presented pilot study deserves attention in the context of mutual respiratory and cardiovascular systems interplay. It may also be useful in cases where the peripheral pulse wave propagation helps assess the respiratory function.

Background Although preterm birth predisposes for cardiovascular disease, recent studies in children indicate normal blood pressure and arterial stiffness. This prospective cohort study therefore assessed blood pressure and arterial stiffness in adolescents born very preterm due to verified fetal growth restriction (FGR). Methods Adolescents (14 (13–17) years; 52% girls) born very preterm with FGR (preterm FGR; n = 24) and two control groups born with appropriate birth weight (AGA), one in similar gestation (preterm AGA; n = 27) and one at term (term AGA; n = 28) were included. 24-hour ambulatory blood pressure and aortic pulse wave velocity (PWV) and distensibility by magnetic resonance imaging were acquired. Results There were no group differences in prevalence of hypertension or in arterial stiffness (all p ≥ 0.1). In boys, diastolic and mean arterial blood pressures increased from term AGA to preterm AGA to preterm FGR with higher daytime and 24-hour mean arterial blood pressures in the preterm FGR as compared to the term AGA group. In girls, no group differences were observed (all p ≥ 0.1). Conclusions Very preterm birth due to FGR is associated with higher, yet normal blood pressure in adolescent boys, suggesting an existing but limited impact of very preterm birth on cardiovascular risk in adolescence, enhanced by male sex and FGR. Impact Very preterm birth due to fetal growth restriction was associated with higher, yet normal blood pressure in adolescent boys. In adolescence, very preterm birth due to fetal growth restriction was not associated with increased thoracic aortic stiffness. In adolescence, very preterm birth in itself showed an existing but limited effect on blood pressure and thoracic aortic stiffness. Male sex and fetal growth restriction enhanced the effect of preterm birth on blood pressure in adolescence. Male sex and fetal growth restriction should be considered as additional risk factors to that of preterm birth in cardiovascular risk stratification.
