Reducing Visit-To-Visit Variability in Systolic Blood Pressure for Im¬proving the Progression of Carotid Atherosclerosis and Endothe¬lial Dysfunction in Patients with Hypertension Management |
|
| چکیده انگلیسی مقاله |
Background: Visit-to-visit variability (VVV) in blood pressure (BP) creates challenges to hypertension control and was independent associated with increased all-cause mortality in hypertensive patients. The major goal of the present study was to investigate the association of VVV in systolic (S)BP with progression of carotid atherosclerosis and endothelial dysfunction in on-treated hypertensive patients. Methods : Overall, 356 hypertensive patients were enrolled and completed the trial. Clinic BP was measured at baseline and at 3 monthly thereafter. Carotid artery ultrasound and endothelial function were evaluated at baseline and annually follow-up visit. VVV in BP was assessed by standard deviation (SD) and coefficient of variation (CV) of serial follow-up BP measurements. The patients were divided into low, middle, and high group by tertile of SD in SBP. Results : Decrease percentage of maximum intima-media thickness (IMT) and stiffness index β and increase percentage of brachial flow-mediated dilation (FMD) and nitric oxide (NO) in lower groups were significant greater than in higher groups ( P < 0.05). Change percentage of stiffness index β and endothelin-1 positively, and change percentage of FMD and NO negatively correlated with SD, CV, maximum, and delta of SBP ( P < 0.05). SD and CV of SBP were risk factors for change percentage of IMT, stiffness index β, FMD, NO, and endothelin-1 independently of other influential factors, such as age, and mean SBP. Conclusion : Excessive VVV in SBP maybe increase carotid atherosclerosis and impair endothelial function in on-treated hypertensive patients. Reducing VVV in SBP is benefit for patients with hypertension management. Keywords : Blood pressure variability, Atherosclerosis, Endothelial dysfunction, Antihypertension |
