Abstract

We investigated whether angiotensin II receptor blockers (ARBs) and angiotensin converting enzyme inhibitors (ACE-Is) are more strongly associated with Alzheimer's disease (AD), vascular dementia (VaD), and other dementias, than other anti-hypertensive drugs. We conducted a nested case-control analysis within the UK general practice research database, with prospectively recorded anti-hypertensive prescribing data. We sampled cases aged ≥60 years and diagnosed between 1997–2008 (5,797 with AD, 2,186 with VaD, 1,214 with unspecified/other dementia) which were matched to up to four controls by age, general practice and gender. We computed odds-ratios and dose response effects for AD, vascular and unspecified/other dementia, comparing those prescribed ARBs or ACE-Is for at least six months with patients prescribed other anti-hypertensives. We controlled for matching factors, co-morbidities, smoking status, an area measure of socioeconomic status, consultation rate and blood pressure and accounted for reverse causality by introducing time-lags of up to eight years prior to diagnosis/index date. Patients diagnosed with AD, vascular and unspecified/other dementia had fewer prescriptions for ARBs and ACE-Is. Inverse associations with AD were strongest for ARBs (odds-ratio; 0.47, 95%CI, 0.37–0.58) compared with ACE-Is (odds-ratio; 0.76, 95%CI, 0.69–0.84) (p difference < 0.001). Associations of ARBs with AD were stronger than for vascular dementia (p difference = 0.01) and unspecified/other dementia (p difference = 0.23). There were inverse dose-response relationships between ARBs and ACE-Is with AD (both p trend < 0.01). The inverse association of ACE-Is with AD diminished when using longer time lags but the ARB-AD association persisted. Patients with AD were around half as likely to be prescribed ARBs. Further randomized controlled trial evidence is required to rigorously test these findings.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
