Key result
Pulse wave velocity does not differ between aortic disease and nonaortic atherosclerotic vascular disease.
Why the study?
PWV is used for cardiovascular risk stratification in patients with aortic aneurysm, but it may be affected by aortic disease.
Does pulse wave velocity differ between patients with nonaortic atherosclerotic vascular disease, treated aortic disease, and untreated aortic disease?
Observational (n=381)
No

Pulse wave velocity is primarily driven by age and systolic blood pressure rather than the presence or treatment status of aortic disease, highlighting the importance of blood pressure control.
Background: Patients with an aortic aneurysm are at high cardiovascular risk. Pulse wave velocity (PWV) is used as a parameter for risk stratification but may be affected by aortic disease (AoD). This study aimed to investigate the dependence of PWV on treated or untreated AoD and to identify modifiable factors of PWV. Methods: The measurement of PWV with the Mobil-O-Graph was performed fully automatically in a collective of 381 patients (75.6% male and 24.4% female). Of all patients, 53.8% had nonaortic atherosclerotic vascular disease (AVD), 28.9% had treated AoD, and 17.3% had untreated AoD. Results: There was a statistically significant effect of age (R2 = 0.838) and current systolic blood pressure (SBP) on PWV (page corrected < 0.05). After correction for age, no statistically significant difference was found between the PWV of men and women, patients with different body weights or degrees of chronic kidney disease, diabetics and nondiabetics, and smokers and nonsmokers. Comparison between patients with nonaortic AVD and treated or untreated AoD revealed no statistically significant differences (PWVnonaortic AVD 10.0 ± 1.8 m/s, PWVtreated AoD 10.0 ± 1.5 m/s, PWVuntreated AoD 9.8 ± 1.6 m/s; page corrected > 0.05). Conclusions: PWV determined with the Mobil-O-Graph correlated with age and current SBP. Neither aortic disease versus nonaortic AVD, its treatment, nor other cardiovascular risk factors had a significant effect on PWV. Successful blood pressure control is crucial to avoid high PWV and thus an increase in cardiovascular events.

Schierling et al. (2022) conducted an observational in Aortic disease and nonaortic atherosclerotic vascular disease (n=381). Aortic disease vs. Nonaortic atherosclerotic vascular disease was evaluated on Pulse wave velocity (PWV) (p=>0.05). Pulse wave velocity was significantly affected by age and systolic blood pressure, but showed no significant difference between patients with aortic disease and those with nonaortic atherosclerotic vascular disease.
