【 摘 要 】

Introduction: Changes in arterial stiffness in hemodialysis patients occur both, in elastic and muscular vessels but only the aortic Pulse Wave Velocity (PWV) has demonstrated to be a high prognostic value index, however, muscular arteries are not involved in the aortic PWV measurement. Objectives: The purpose of this research was: a) to evaluate the aortic and carotid-radial PWV of hemodialysis patients, b) to repeat these measurements in the same cohort after 5 years comparing four different arterial stiffness indexes. Methods: 23 hemodialyzed patients carotid-femoral PWV (PWVcf) and  carotidradial (PWVcr) were evaluated and calculations were as follows: PWV ratio, PWV difference (/PWV), PWV mismatch and PWV percentage change (%PWV). These evaluations were performed using data obtained in 2007 (Time 1) and 2012 (Time 2). Results: PWV ratio showed a significant increase between measurements performed in Time 1 and 2 (from 1.1±0.3 to 1.4±0.4; p≤0.01). Similar increases in negative terms were found when /PWV was calculated from -0.9±3.0 to -2.7±2.9; p≤0.05). Calculated values of PWV mismatch increased significantly > (negative values) between Time 1 and 2 (from 0.0±0.1 to -0.1±0.1; p≤0.02) Percent changes of PWV between Time 1 and 2 (negative values) showed a significant increase (from -4.8±22.0 to -21.5±24.2; p≤0.05). Conclusions: Stiffness indexes, obtained in hemodialyzed patients including both elastic and muscular arteries used in this research showed statistically significant differences when two measures with 5 years interval were compared. However significance levels were not similar.
