We read the following article with great interest: “Aortic Arch Calcification on Routine Chest Radiography is Strongly and Independently Associated with Non-Dipper Blood Pressure Pattern”. In this study, the aim was to evaluate a possible relationship between aortic arch calcification on chest radiographs and the non-dipper blood pressure pattern. Altogether, 406 patients were analyzed and divided into two groups: dipper and non-dipper. Approximately 261 (64%) patients presented the pattern of non-dipper blood pressure, against 145 (36%) with dipper blood pressure. It was found that the non-dipper group presented a higher prevalence of aortic arch calcification (70% vs. 33%, p<0.0001).
