In the present study, we report the in-hospital mortality, hospitalization length, and treatment methods for patients with STelevation myocardial infarction (STEMI) in Tehran Heart Center (THC). <jats:bold>Methods<\/jats:bold>: Records pertaining to patients with STEMI from March 2006 to March 2017 were extracted from the databases of THC. Besides a description of temporal trends, multivariable regression analysis was used to find factors associated with in-hospital mortality. <jats:bold>Results<\/jats:bold>: During the study period, 8,295 patients were admitted with STEMI with a mean age of 60.4 \u00b1 12.5 years. Men accounted for 77.5% of the study population. Hospitalization length declined from 8.4 to 5.2 days, and in-hospital mortality was reduced from 8.0% to 3.9% (both P values &lt; 0.001). In a multivariable model adjusted for age, sex, conventional cardiac risk factors, prior cardiac history, and indices of event severity, primary percutaneous coronary intervention (PCI) (OR: 0.280, 95% CI: 0.186 to 0.512; P&lt;0.001), coronary artery bypass graft (CABG) surgery (OR: 0.482, 95% CI: 0.220 to 0.903; P=0.025), and rescue or facilitated PCI (OR: 0.420, 95% CI: 0.071 to 0.812; P=0.001) were all associated with reduced in-hospital mortality in comparison with medical treatment. Furthermore, primary PCI was a crucial protective factor against prolonged length of hospital stay (OR: 0.307, 95% CI: 0.266 to 0.594; P&lt;0.001). <jats:bold>Conclusion<\/jats:bold>: In-hospital mortality and hospitalization length were almost halved during the study period, and primary PCI has now replaced thrombolysis in the management of STEMI. <\/jats:p>","DOI":"10.34172\/aim.2020.53","type":"journal-article","created":{"date-parts":[[2020,9,4]],"date-time":"2020-09-04T07:25:32Z","timestamp":1599204332000},"page":"514-521","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Twelve-Year History of STEMI Management in Tehran Heart Center: Concomitant Reduction of In-Hospital Mortality and Hospitalization Length"],"prefix":"10.34172","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4950-8334","authenticated-orcid":true,"given":"Seyedmohammad","family":"Saadatagah","sequence":"first","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saeed","family":"Ghodsi","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Negar","family":"Omidi","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamidreza","family":"Poorhosseini","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mojtaba","family":"Salarifar","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saeed","family":"Sadeghian","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Alidoosti","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyed Ebrahim","family":"Kassaian","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan","family":"Aghajani","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyedeh Hamideh","family":"Mortazavi","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaveh","family":"Hosseini","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6695-7751","authenticated-orcid":true,"given":"Babak","family":"Geraiely","sequence":"additional","affiliation":[{"name":"Tehran Heart Center (THC), Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2020,8,1]]},"container-title":["Archives of Iranian Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-514.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-514.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,4]],"date-time":"2020-09-04T07:25:32Z","timestamp":1599204332000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.aimjournal.ir\/Article\/aim-8043"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,1]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2020,8]]}},"URL":"https:\/\/doi.org\/10.34172\/aim.2020.53","relation":{},"ISSN":["1029-2977","1735-3947"],"issn-type":[{"value":"1029-2977","type":"print"},{"value":"1735-3947","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,1]]},"assertion":[{"value":"Academy of Medical Sciences of the I.R.
