BPV associated with imaging features of SSI on MRI

Abstract

Objectives: A retrospective study was performed to investigate the relationship between blood pressure variability (BPV) and imaging features of single small infarction (SSI) on magnetic resonance imaging (MRI). Materials and Methods: Two hundreds and five patients with SSI and 120 healthy subjects matched with age and sex as the control group were enrolled into this study. All subjects came from the Affiliated Hospital to Qingdao University and Qingdao Municipal Hospital from October 2011 to June 2016. Research subjects were classified into different groups. Blood pressure was measured once a day and recorded during the hospitalization period (7–10 days). The followed up data of patients after discharging from hospital was collected from the follow-up records. Results: Twenty-four hours BPV (SBPMean, DSBPMax, DSBPSD, NDBPMax, NDBPSD, and DDBPCV), day-to-day, and visit-to-visit BPV (SBPMax, SBPSD, DBPMax, and DBPSD) in the SSI group were significantly higher than that in control group. Compared with the giant lacunar group, day-to-day BPV (SBPMean, SBPMax, SBPSD, SBPCV, DBPMean, DBPMax, DBPSD), and visit-to-visit BPV (SBPMean, SBPMax, SBPSD, DBPMean, DBPMax, DBPSD) were significantly higher in the small lacunar infarct group (p
