Abstract
The current case is a 57-year-old male who had no history of cardiovascular, hypertensive, renal, diabetic, or lipid problems, with a BMI of 24.7 kg/m². He underwent pulse wave velocity (PWV) measurement, with results showing a cardio–ankle vascular index (CAVI) of 11.1/10.7 and an ankle–brachial index (ABI) of 0.98/1.31 (right/left), respectively. The inter-limb difference of 0.33 in ABI exceeded the standard threshold for clinically significant asymmetry. The case remained asymptomatic and showed no clinical signs of peripheral arterial disease (PAD). Because of the discrepancy between ABI and CAVI values, further interpretation of the vascular indices was considered necessary to determine their potential clinical significance.
