Key result
Treated hypertensive subjects had a significantly higher risk for first stroke than untreated subjects based on home blood pressure (RH 1.48) and casual blood pressure (RH 1.78).
Why the study?
Does home blood pressure better predict the risk of first stroke compared to casual blood pressure in treated and untreated individuals?
Cohort (n=2,390)
Does home blood pressure better predict the risk of first stroke compared to casual blood pressure in treated and untreated individuals?
Effect estimate: RH 1.48
Home blood pressure measurement is superior to casual screening blood pressure for assessing stroke risk, particularly in patients receiving antihypertensive treatment.
No takes yet. Share an insight, caveat, or question.
May signal residual stroke risk in treated hypertensives; leaves open whether home BP refines prediction over casual measures in trials.
Yasui et al. (2010) conducted a cohort in Hypertension (n=2,390). Antihypertensive medication vs. Untreated individuals was evaluated on First stroke (RH 1.48). Treated hypertensive subjects had a significantly higher risk for first stroke than untreated subjects based on home blood pressure (RH 1.48) and casual blood pressure (RH 1.78).
