Home SBP extremes signal higher mortality risk in older men; extends casual BP U-shape to home monitoring yet leaves causality and interventions open.
Is there an association between the average level of home systolic blood pressure and 4-year mortality in community-dwelling older people?
Both high and low home systolic blood pressure are independent risk factors for mortality in older men, with low SBP linked to noncardiovascular deaths and high SBP to cardiovascular deaths.
Okumiya et al. (1999) studied this question.
