We hypothesized that patients with IS with a medical history of MI may experience more severe strokes and have a higher risk of in\u2010hospital mortality and complications than patients with IS without a medical history of MI.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              Consecutive in\u2010hospital data were extracted from the China Stroke Center Alliance database from August 2015 to July 2019. Patient characteristics, hospital tests, in\u2010hospital mortality, and complications were analyzed and compared in patients with IS with or without a history of MI. Of 893\u00a0429 patients with IS, we identified 81\u00a0646 (9.1%) patients with a history of MI (MI group). Compared with patients with IS without MI, MI group patients were older, had a lower prevalence of current smoking, had a higher prevalence of a relative medical history, and took more medications before admission. Compared with the group with IS without MI, the MI group had a higher National Institute of Health Stroke Scale score after onset (4.0 versus 3.0; Hodges\u2010Lehmann estimator, 22.5) and a higher proportion of severe strokes (National Institute of Health Stroke Scale score \u226515) (7.1% versus 4.4%; absolute standardized difference=11.6%). In the fully adjusted models, the risk of in\u2010hospital mortality was higher in the MI group (odds ratio [OR], 1.74; 95% CI, 1.57\u20131.92;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001).
