Key result
In stroke survivors on antihypertensives, a nocturnal blood pressure dip was associated with higher stroke recurrence compared to nondippers (12.5% vs 1.5% per patient-year; P<0.05).
Why the study?
Does a nocturnal blood pressure dip increase the risk of stroke recurrence and new silent ischemic lesions in patients with chronic ischemic cerebrovascular disease?

Nocturnal dipping may identify higher recurrence risk in treated stroke survivors; leaves open whether modifying patterns improves outcomes.
Cohort (n=81)
Does a nocturnal blood pressure dip increase the risk of stroke recurrence and new silent ischemic lesions in patients with chronic ischemic cerebrovascular disease?
Absolute Event Rate: 12.5% vs 1.5%
p-value: p=<0.05
In stroke survivors treated with antihypertensive agents, a nocturnal blood pressure dip is associated with a significantly higher risk of stroke recurrence and new silent ischemic brain lesions.
Nakamura et al. (1995) conducted a cohort in Chronic ischemic cerebrovascular disease (n=81). Nocturnal blood pressure dip vs. Nondippers was evaluated on Stroke recurrence (p=<0.05). In stroke survivors on antihypertensives, a nocturnal blood pressure dip was associated with higher stroke recurrence compared to nondippers (12.5% vs 1.5% per patient-year; P<0.05).
