Key result
Summer months were associated with lower daytime blood pressure but a higher prevalence of isolated nocturnal hypertension (15.2% vs 9.8%, P=0.003) compared to winter.
Why the study?
Do summer months influence ambulatory blood pressure monitoring values compared to winter months in patients referred for hypertension evaluation?

Seasonal BP variation may require year-round ambulatory monitoring; leaves open clinical implications of summer-associated isolated nocturnal hypertension.

While summer is associated with lower daytime blood pressure, it is paradoxically associated with higher night-time blood pressure, non-dipping patterns, and isolated nocturnal hypertension.
Fedecostante et al. (2012) conducted an observational in Hypertension (n=1,395). Summer season (July and August) vs. Winter season (January and February) was evaluated on Isolated nocturnal hypertension (INH) (p=0.003). Summer months were associated with lower daytime blood pressure but a higher prevalence of isolated nocturnal hypertension (15.2% vs 9.8%, P=0.003) compared to winter.
