Whether novel artificial intelligence\u2013based automated analyses deliver similar information for risk stratification is unknown. Therefore, this study aimed to investigate feasibility and prognostic implications of artificial intelligence\u2013based, commercially available software analyses.<\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n Cardiovascular magnetic resonance data (n=1017 patients) from 2 myocardial infarction multicenter trials were included. Analyses of biventricular parameters including ejection fraction (EF) were manually and automatically assessed using conventional and artificial intelligence\u2013based software. Obtained parameters entered regression analyses for prediction of major adverse cardiac events, defined as death, reinfarction, or congestive heart failure, within 1 year after the acute event. Both manual and uncorrected automated volumetric assessments showed similar impact on outcome in univariate analyses (left ventricular EF, manual: hazard ratio [HR], 0.93 [95% CI 0.91\u20130.95];\n P<\/jats:italic>\n <0.001; automated: HR, 0.94 [95% CI, 0.92\u20130.96];\n P<\/jats:italic>\n <0.001) and multivariable analyses (left ventricular EF, manual: HR, 0.95 [95% CI, 0.92\u20130.98];\n P<\/jats:italic>\n =0.001; automated: HR, 0.95 [95% CI, 0.92\u20130.98];\n P<\/jats:italic>\n =0.001). Manual correction of the automated contours did not lead to improved risk prediction (left ventricular EF, area under the curve: 0.67 automated versus 0.68 automated corrected;\n P<\/jats:italic>\n =0.49). There was acceptable agreement (left ventricular EF: bias, 2.6%; 95% limits of agreement, \u22129.1% to 14.2%; intraclass correlation coefficient, 0.88 [95% CI, 0.77\u20130.93]) of manual and automated volumetric assessments.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n User\u2010independent volumetric analyses performed by fully automated software are feasible, and results are equally predictive of major adverse cardiac events compared with conventional analyses in patients following myocardial infarction.<\/jats:p>\n <\/jats:sec>\n \n Registration<\/jats:title>\n \n URL:\n https:\/\/www.clinicaltrials.gov<\/jats:ext-link>\n ; Unique identifiers: NCT00712101 and NCT01612312.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.120.016612","type":"journal-article","created":{"date-parts":[[2020,9,2]],"date-time":"2020-09-02T09:01:16Z","timestamp":1599037276000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":37,"title":["Fully Automated Cardiac Assessment for Diagnostic and Prognostic Stratification Following Myocardial Infarction"],"prefix":"10.1161","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1508-1125","authenticated-orcid":false,"given":"Andreas","family":"Schuster","sequence":"first","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0505-2582","authenticated-orcid":false,"given":"Torben","family":"Lange","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f6ren J.","family":"Backhaus","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolin","family":"Strohmeyer","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia C.","family":"Boom","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonas","family":"Matz","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pneumology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"},{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes T.","family":"Kowallick","sequence":"additional","affiliation":[{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"},{"name":"Institute for Diagnostic and Interventional Radiology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim","family":"Lotz","sequence":"additional","affiliation":[{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"},{"name":"Institute for Diagnostic and Interventional Radiology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Steinmetz","sequence":"additional","affiliation":[{"name":"German Centre for Cardiovascular Research (DZHK), partner site G\u00f6ttingen G\u00f6ttingen Germany"},{"name":"Department of Pediatric Cardiology University Medical Center G\u00f6ttingenGeorg\u2010August University G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shelby","family":"Kutty","sequence":"additional","affiliation":[{"name":"Helen B.
