Abstract: Objective To study the association between morning surge (MS) of systolic blood pressure (SBP) and white matter lesions in elderly essential hypertensive (EH) patients.Methods Three hundred and thirty-seven elderly EH patients from Zhangqiu of Shandong Province were divided into MS group (n=150) and non-MS group (n=187).Their 24 h ambulatory SBP was monitored.Their white matter hyperintensity (WMH) was assessed according to their brain MRI.Results The total WMH,periventricular WMH,and deep WMH were significantly higher in MS group than in non-MS group (P＜0.01).The MS of SBP was positively related with the total WMH,periventricular WMH,and deep WMH (r=0.561,r=0.563,r=0.283,P＜0.01),and was an independent risk factor for total WMH,periventricular WMH,and deep WMH after adjustment for confunders (r=0.479,r=0.486,r=0.208,P＜0.01).Conclusion MS of SBP is an independently risk factor for WMH in elderly EH patients.
