Night-time diastolic blood pressure variability relates to stroke recurrence in patients who had ischaemic stroke with small artery occlusion.

High night-time DBPV was associated with increased risk of stroke recurrence among patients who had IS of SAO subtype. The results of this study have implications for the secondary prevention management and future research of patients who had IS of SAO subtype. The association between BPV and stroke recurrence in patients who had IS of LAA subtype and SAO subtype should be investigated in larger, population-based studies.
