Variables, including demographics, medical history, hemodynamic condition and laboratory results, were collected and analyzed to find risk factors predicting mortality during hospitalization. \r\nResults: Amonga total of 384 patients enrolled in this study, the hospital mortality rate was 23.4%. By multivariable stepwise regression analysis, nine independent significant predictors associated with mortality during hospitalization were identified: history of stoke, cardiac shock, Killip class III to IV, ventricular tachycardia, pulse rate \u2265 100 bpm and EF \u2264 40% at presentation, in-hospital bleeding, initial serum creatinine concentration \u2265 177 umol\/L and elevated initial WBC level. Prior angina was identified as a protective factor. Hosmer-Lemeshow test indicated good fitness of the predicting variables.\r\nConclusion: Patients aged 80 and over have high mortality during hospitalization, and the risk prediction factors are clinically useful for predicting mortality in old patients with AMI.<\/jats:p>","DOI":"10.1532\/hsf.2265","type":"journal-article","created":{"date-parts":[[2019,4,16]],"date-time":"2019-04-16T13:52:52Z","timestamp":1555422772000},"page":"E165-E169","source":"Crossref","is-referenced-by-count":5,"title":["Risk Factors for Predicting Mortality among Old Patients with Acute Myocardial Infarction during Hospitalization"],"prefix":"10.31083","volume":"22","author":[{"given":"Liwei","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ling","family":"Han","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingguang","family":"Luo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2019,4,16]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2265\/3399","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2265\/3399","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:14:37Z","timestamp":1766398477000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/22\/2\/10.1532\/hsf.2265"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4,16]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,2,28]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.2265","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"type":"electronic","value":"1522-6662"},{"type":"print","value":"1098-3511"}],"subject":[],"published":{"date-parts":[[2019,4,16]]}}}
