Association of dipping pattern of blood pressure and atherosclerotic burden of coronary arteries in hypertensive patients

OpenAlex English

Aim The aim of this study was to determine the association between the dipping pattern of BP and coronary artery disease in hypertensive patients.Material and methods A total of 356 hypertensive patients were included in the study. The results of ambulatory BP monitoring, echocardiography, and coronary computerised tomographic angiography were evaluated retrospectively. The patients were divided into two groups on the basis of their ambulatory BP monitoring: 1) patients with the dipping pattern of BP; 2) patients with the non-dipping pattern (NDP).Results Among the 356 patients, 145 were male (40.7 %). The smoking status was higher in patients with NDP (p=0.023). The statin usage in patients with the dipping pattern was higher in patients with NDP (p=0.027). There were no significant differences in the echocardiographic findings. 58.6 % of the patients without plaque formation had the dipping pattern of BP (p<0.05), however 84.4 % of patients with >50 % plaque formation had the NDP of BP (p<0.001).Conclusion The NDP of BP might be related to the increased atherosclerotic process in coronary arteries, and pa-tients with NDP might have an increased atherosclerotic burden for coronary arteries when compared with patients with a dipping pattern.
