Antihypertensive medications and risk of Alzheimer's disease: Evidence for specific medication use

open access: yesAlzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.
Abstract BACKGROUND Hypertension is a modifiable risk factor for Alzheimer's disease (AD). Specific antihypertensive classes may lower/increase AD risk by affecting the renin–angiotensin–aldosterone system. METHODS We investigated AD risk in relation to antihypertensive medications in a population‐based study of 33,714 incident AD cases and 897,872 ...

Self‐Administered Etripamil Nasal Spray Slows Ventricular Rate in Patients With Atrial Fibrillation: A Post Hoc Analysis of the NODE‐303 Study

open access: yesJournal of Cardiovascular Electrophysiology, Volume 37, Issue 4, Page 859-863, April 2026.
ABSTRACT Introduction Currently, there are no available fast‐acting agents to control the ventricular rate (VR) during atrial fibrillation (AF) episodes that can be self‐administered by patients on an as‐needed basis without medical supervision. Here, we aim to evaluate the effect of intranasal etripamil on VR in patients treating presumed paroxysmal ...
