Even though these conversations are tough, people want to have it. With what we know about the rate of cognitive decline in this patient population, there is a major need to meet patients where they are with clarity and compassion to improve overall care in heart failure.\u201d<\/p>\n<p><strong>Additional authors<\/strong>: Hanyu Li, M.S., Min Zhang, Ph.D., Rachael Whitney, Ph.D., Brahmajee K.

Circulation Heart Failure<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p><strong>Trajectory of Cognitive Function After Incident Heart Failure<\/strong><\/p>\n<p>BACKGROUND:<\/p>\n<p>The magnitude of cognitive changes after incident heart failure (HF) is unclear. We assessed whether incident HF is associated with changes in cognition after accounting for pre-HF cognitive trajectories and known determinants of cognition.<\/p>\n<p>METHODS:<\/p>\n<p>This pooled cohort study included adults without HF, stroke, or dementia from 6 US population-based studies from 1971 to 2019. Linear mixed-effects models estimated cognitive change with incident HF diagnosis and the rate of cognitive change over the years after HF, controlling for pre-HF cognitive trajectories and participant factors.<\/p>\n<p>Outcomes included change in global cognition (primary outcome), executive function, and memory (secondary outcomes). Cognitive outcomes were standardized to a\u00a0t\u00a0score metric (mean [SD], 50 [10]); a 1-point difference represented a 0.1-SD difference in cognition.<\/p>\n<p>RESULTS:<\/p>\n<p>We included 29\u2005614 adults (mean [SD] age was 61 [10] years, 55% female, 70% White). During a median follow-up of 6.6 (Q1\u2013Q3, 5.0\u201319.8) years, 1407 (5%) adults received an incident diagnosis of HF. Incident HF diagnosis was associated with initial decreases in global cognition (\u22121.1 points [95% CI, \u22121.4 to \u22120.8]) and executive function (\u22120.6 points [95% CI, \u22121.0 to \u22120.3]). Larger decreases in global cognition after HF were seen with older age, female sex, and White race.<\/p>\n<p>Participants with incident HF diagnosis demonstrated faster and long-term declines in global cognition (\u22120.1 points per year [95% CI, \u22120.2 to \u22120.1]) and executive function (\u22120.2 points per year [95% CI, \u22120.2 to \u22120.1]). The change in memory with incident HF diagnosis was not statistically significant but showed a similar trend with an initial decline of \u22120.5 points (95% CI, \u22121.4 to +0.3) and a slope of \u22120.1 points per year (95% CI, \u22120.3 to 0.0).<\/p>\n<p>CONCLUSIONS:<\/p>\n<p>In this pooled cohort study, incident HF diagnosis was associated with initial decreases in global cognition and executive function and faster, persistent declines in these domains at follow-up.<\/p>\n","protected":false},"excerpt":{"rendered":"Summary: A large new study reveals that heart failure significantly accelerates cognitive decline, causing affected individuals to mentally&hellip;\n","protected":false},"author":2,"featured_media":2839,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[1152,215,1707,1033,400,105,1708,219,233,220,16,15,1709],"class_list":["post-2838","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-aging","tag-brain-research","tag-cardiovascular-disease","tag-cognition","tag-cognitive-decline","tag-health","tag-heart-failure","tag-neurobiology","tag-neurology","tag-neuroscience","tag-uk","tag-united-kingdom","tag-university-of-michigan"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114283421621867757","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/2838","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=2838"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/2838\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/2839"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=2838"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=2838"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=2838"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
