- More than a third of patients with a history of both stroke and hypertension have uncontrolled BP.
Why this matters
- The risk for recurrent stroke rises with BP.
- 37.1% of cohort had uncontrolled BP on examination.
- 80.4% of this subset were receiving antihypertensive medication.
- Among all 84.7% of individuals receiving antihypertensive medication:
- 59.2% were receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers.
- 43.8% were receiving β-blockers.
- 41.6% were receiving diuretics.
- 31.5% were receiving calcium channel blockers.
- Proportion with controlled BP was highest among thiazide diuretic users (70.5%), lowest among users of "other" antihypertensives (51.2%).
- Between 2005-2006 and 2015-2016:
- Use of diuretics declined (from 49.4% to 35.7%; P=.005).
- Use of other antihypertensives remained stable.
- The US nationally representative cross-sectional survey using data from 2005 to 2016 for 4,971,136 individuals aged ≥20 years with history of both stroke and hypertension (National Health and Nutrition Examination Survey).
- Main outcome: uncontrolled BP (>140/90 mm Hg) on physical examination.
- Funding: None disclosed.
- Analyses were limited by unmeasured and residual confounding.
- Stroke was self-reported.
- Subtypes of stroke were unknown.
- BP was measured just once.
- Generalizability is unknown.
