Abstract

Aim: To determine the predictive value of high cardiovascular risk of baPWV and the prevalence of peripheral arterial disease in hypertensive patients. Subjects and methods: 190 patients; 109 men, 81 women; mean age 61±17 years were diagnosed the primary hypertension alone or hypertension with diabetes. All were measured  their extremity blood pressure by using the VP Plus 1000 pulse wave velocity meter. Left arm blood pressure was used to confirm the diagnosis and classify hypertension according to  the ESH 2021. Diagnosis of peripheral arterial disease was based on the ABI index according to the recommendations of the ESC. Upper limb peripheral arterial disease was confirmed by subclavian angiography. Results: The right pulse wave velocity (baPWV) value in hypertensive patients with target blood pressure (normal blood pressure) was 1382.0 ± 211 cm/s; patients with slightly high cardiovascular risk were 1590.2 ± 173.6 cm/s; patients with high cardiovascular risk were: 2101.0 ± 563.4 cm/s and patients with suspected embolism were 2312.5 ± 949.5 cm/s; corresponding left pulse wave velocities were: 1423.3 ± 208.5 cm/s, 1586.5 ± 185.2, 2118.9 ± 586.6 cm/s, 2304.3 ± 983.4 cm/s. The cutoff value for predicting high cardiovascular risk of right baPWV was 1739 cm/s, left baPWV was 1762 cm/s. The rate of peripheral arterial disease in hypertensive patients with and without diabetes was 27.4%. Conclusion: Brachial-ankle pulse wave velocity (baPWV) increases gradually with the level of cardiovascular risk. Pulse wave velocity has a good predictive value for high cardiovascular risk with high sensitivity and specificity. Over quarter hypertensive patients had the peripherial arterial disease, the diabetes caused incresing its prevalence.
