Aortic valve replacement linked to lower dementia risk
Compared with medical management, valve replacement was linked to lower Alzheimer’s disease risk, with a hazard ratio—a relative risk measure—of 0.75.Compared with medical management, valve replacement was linked to lower Alzheimer’s disease risk, with a hazard ratio—a relative risk measure—of 0.75.
