Study on the Relationship between Blood Pressure Variability and Atherosclerosis in Elderly Patients with Essential Hypertension

Objective To investigate the relationship between blood pressure variability and the arterial distensibility in elderly patients with essential hypertension.Methods A total of 126 elderly hypertensive patients were divided into two groups.Auto-survey atherosclerosis apparatus was applied to examine brachial-ankle pulse wave velocity(baPWV).Ambulatory blood pressure monitoring was examined to calculate the systolic and diastolic BP variability.Results BaPWV were significantly higher in EH+CHD group than in EH group(P0.05).DSBP-SD and 24hSBP-SD in EH patients with CHD group were significantly higher than those in EH patients without CHD group(P0.05 or P0.01).Pearson correlation analysis showed that 24 hSBP-SD,DSBP-SD were significantly related to PWV.Conclusion There was positive association between blood pressure variability and arterial distensibility in hypertension patients.
