Cognitive Impairment in Adults with Incident HF

J Card Fail; ePub 2018 Dec 22; Sterling, et al

In a cohort study, nearly 15% of adults with incident heart failure (HF) had cognitive impairment (CI), suggest that the majority of cognitive decline occurs after HF diagnosis. The REasons for Geographic and Racial Differences in Stroke (REGARDS) study included 436 participants (mean age 70.3 years, 47% female, 39% black). Researchers compared the prevalence of CI among those with incident HF to the prevalence of CI among an age, sex, and race-matched cohort without HF. They found:

  • 14.9% of adults with incident HF had CI.
  • Age, race, gender, education, and anticoagulation use were associated with CI.
  • The prevalence of CI among an age-sex-race match cohort without HF was 13.4%.
  • The majority of CI in HF occurred after HF diagnosis.
