Association of high-sensitivity cardiac troponin I levels below the sex-specific 99th percentile with late-life dementia: the Perth Longitudinal Study of Ageing Women.

BackgroundElevated high-sensitivity cardiac troponin (hs-cTn) levels are linked with cardiovascular disease and cognitive impairment, both of which are strong risk factors for late-life dementia (LLD). This study examined the association between hs-cTnI levels below the sex-specific 99th percentile for myocardial injury and the incidence of LLD in older women.Methods986 community-dwelling women aged ≥70 years without prior LLD and with hs-cTnI
