• Hypertension and intracranial artery stenosis (ICAS) are closely related; however, few studies have compared the strength of the relationship between strictly measured office and out-of-office blood pressure (BP) measurements. The relationship of day-by-day or short-term variability in BP to asymptomatic ICAS also remains unclear. In apparently healthy 677 men (mean age, 70 years) from a population-based cohort, we examined the association of strictly measured office BP and 7-day home BP with ICAS on magnetic resonance angiography. We conducted 24-h ambulatory BP monitoring in 468 of the men. Variability indices included day-by-day, daytime, and night-time variability, nocturnal decline, and morning pressor surge. Any ICAS was defined as either mild (1-49%) or severe (≥50%) stenosis. We observed mild and severe ICAS in 153 (22.6%) and 36 (5.3%) participants, respectively. In multivariable-adjusted Poisson regression with robust error variance, higher SBP in office, home, or ambulatory BP monitoring was associated with the presence of any or severe ICAS. The associations with ICAS were comparable between office, home, and ambulatory SBP (all heterogeneity P values >0.1). Independent of mean SBP, greater nocturnal decline or morning pressor surge, but not day-by-day, daytime, or night-time variability, in SBP was associated with higher burden of any or severe ICAS. The magnitude of association of strictly measured office BP for asymptomatic ICAS was comparable with that of BP measured at home or in ambulatory BP monitoring. Circadian BP variation based on ambulatory BP monitoring was positively associated with asymptomatic ICAS burden.
