Özet
Objective: Aortic arch calcification (AAC) is a surrogate marker for arterial stiffness and hypertension-related vascular damage. Renal resistive index (RRI), a renal Doppler ultrasonography parameter, is used to assess renal hemodynamics. In this study, we aimed to evaluate the relationship between RRI and AAC in patients with hypertension. Methods: Patients with hypertension underwent a chest X-ray and renal Doppler ultrasonography. They were divided into two groups according to RRI (group 1: RRI >= 0.70; group 2: RRI <0.70). Two examiners, blinded to the findings of RRI, reviewed the AAC in these patients. The kappa value was detected to be 0.781 and a p value <0.001 was considered significant. Results: The study included 289 hypertensive patients (mean age 63.87 +/- 11.38 years). In 53.6% (n = 155) of the study subjects, RRI was observed to be >= 0.70. Patients with RRI = 70 were older and had more prevalent AAC as well as left ventricular hypertrophy. A multiple linear regression analysis was carried out to test whether presence of AAC significantly predicted RRI. The results of the regression analysis indicated that presence of AAC significantly predicted RRI (beta = 0.053; p < 0.001). Conclusions: A strong and independent relationship was found between AAC on chest X-ray and RRI in patients with hypertension. (C) 2018 The Author(s) Published by S. Karger AG, Basel
