Aim: To investigate the application and the related influencing factors of ultrafast pulse wave velocity (ufPWV) in the evaluation of carotid artery elasticity in patients with Immunoglobulin A nephropathy (IgAN).

Material and methods: A total of 156 IgAN patients and 50 healthy individuals were selected as the control group. The ufPWV technique was employed to measure carotid arterial elasticity parameters, including carotid intima-media thickness (cIMT), pulse wave velocity at the beginning of systole (BS-PWV) and pulse wave velocity at the end of systole (ES-PWV).

Results: Across the three groups (control group, IgAN patients with normal renal function, and IgAN patients with renal dysfunction) there was an increasing trend observed in cIMT, BS-PWV, and ES-PWV. Additionally, ES-PWV exhibited higher sensitivity than BS-PWV. Correlation analysis revealed that BS-PWV and ES-PWV were positively correlated with age, body mass index (BMI), systolic blood pressure (SBP), high-sensitivity C-reactive protein (hs-CRP), creatinine (Cr), blood urea nitrogen (BUN), and uric acid (UA) and negatively correlated with estimated glomerular filtration rate (eGFR).

Conclusion: The ufPWV technique allows for the rapid and direct measurement of arterial elasticity parameters in the neck and represents a novel approach for the early diagnosis and quantitative assessment of arterial stiffness risk in IgAN patients.
