Secondary outcomes were changes in memory and executive function. Outcomes were standardized as mean (SD) T scores of 50 (10); a 1-point difference represented a 0.1-SD difference in cognition. Linear mixed-effects models estimated changes in cognition at the time of MI (change in the intercept) and the rate of cognitive change over the years after MI (change in the slope), controlling for pre-MI cognitive trajectories and participant factors, with interaction terms for race and sex.<\/jats:p><\/jats:sec><jats:sec id=\"ab-noi230029-9\"><jats:title>Results<\/jats:title><jats:p>The study included 30 465 adults (mean [SD] age, 64 [10] years; 56% female), of whom 1033 had 1 or more MI event, and 29\u202f432 did not have an MI event. Median follow-up was 6.4 years (IQR, 4.9-19.7 years). Overall, incident MI was not associated with an acute decrease in global cognition (\u22120.18 points; 95% CI, \u22120.52 to 0.17 points), executive function (\u22120.17 points; 95% CI, \u22120.53 to 0.18 points), or memory (0.62 points; 95% CI, \u22120.07 to 1.31 points). However, individuals with incident MI vs those without MI demonstrated faster declines in global cognition (\u22120.15 points per year; 95% CI, \u22120.21 to \u22120.10 points per year), memory (\u22120.13 points per year; 95% CI, \u22120.22 to \u22120.04 points per year), and executive function (\u22120.14 points per year; 95% CI, \u22120.20 to \u22120.08 points per year) over the years after MI compared with pre-MI slopes. The interaction analysis suggested that race and sex modified the degree of change in the decline in global cognition after MI (race\u2009\u00d7\u2009post-MI slope interaction term, <jats:italic>P<\/jats:italic>\u2009=\u2009.02; sex\u2009\u00d7\u2009post-MI slope interaction term, <jats:italic>P<\/jats:italic>\u2009=\u2009.04), with a smaller change in the decline over the years after MI in Black individuals than in White individuals (difference in slope change, 0.22 points per year; 95% CI, 0.04-0.40 points per year) and in females than in males (difference in slope change, 0.12 points per year; 95% CI, 0.01-0.23 points per year).<\/jats:p><\/jats:sec><jats:sec id=\"ab-noi230029-10\"><jats:title>Conclusions<\/jats:title><jats:p>This cohort study using pooled data from 6 cohort studies found that incident MI was not associated with a decrease in global cognition, memory, or executive function at the time of the event compared with no MI but was associated with faster declines in global cognition, memory, and executive function over time. These findings suggest that prevention of MI may be important for long-term brain health.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamaneurol.2023.1331","type":"journal-article","created":{"date-parts":[[2023,5,30]],"date-time":"2023-05-30T15:31:49Z","timestamp":1685460709000},"page":"723","source":"Crossref","is-referenced-by-count":64,"title":["Association Between Acute Myocardial Infarction and Cognition"],"prefix":"10.1001","volume":"80","author":[{"given":"Michelle C.","family":"Johansen","sequence":"first","affiliation":[{"name":"The Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen","family":"Ye","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alden","family":"Gross","sequence":"additional","affiliation":[{"name":"The Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca F.","family":"Gottesman","sequence":"additional","affiliation":[{"name":"National Institute of Neurological Disorders and Stroke, Bethesda, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dehua","family":"Han","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachael","family":"Whitney","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily M.","family":"Brice\u00f1o","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno J.","family":"Giordani","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Supriya","family":"Shore","sequence":"additional","affiliation":[{"name":"University of Michigan Medical School, Ann Arbor"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitchell S.
