Abstract

Objectives: To describe the characteristics of pulse wave velocity and related factors in elderly patients with chronic coronary syndrome. Materials and methods: A cross-sectional descriptive study was conducted on patients visiting the University Medical Center at Ho Chi Minh City from May 2024 to March 2025. Pulse wave velocity was measured at the carotid - femoral and recorded. Results: A total of 80 patients were included, with a mean age of 67.65 ± 5.79 years. The average PWV was 11.37 ± 2.65m/s, and 67.5% of patients had elevated PWV. Patients with hypertension had higher PWV than those without hypertension (12.11 ± 2.49m/s vs 9.76 ± 2.29m/s). Patients with elevated PWV had a higher prevalence of hypertension (81.5% vs 42.3%) and diabetes mellitus (44.4% vs 26.9%) compared to those with normal PWV. Conclusion: Elevated pulse wave velocity values ​​are quite common in elderly patients with chronic coronary syndrome, occurring in approximately 67.5% of cases. Hypertension and diabetes are two risk factors associated with increased pulse wave velocity.
