Materials and Methods. The 293 cases of patients with myocardial infarction treated in our hospital from August 2017 to August 2021 were selected as the subjects of this retrospective study, 13 cases were shed due to transfer and moving, and the rest were divided into 140 cases each in the emergency and elective groups according to emergency percutaneous coronary intervention (PCI) and elective PCI. The patients\u2019 myocardial infarct volume ventricular volume, microcirculatory obstruction volume ventricular volume, microcirculatory obstruction volume\/myocardial infarct volume, and LVEF, combined with BP and troponin T, were analysed by CMR for comparative analysis, hemodynamic, and cardiac function index differences. Results. The hemodynamics (CO, CI, SV, SI, LVSW1, and LCW) measured at different times were significantly different between the two groups; patients in the emergency group had significantly lower EDV and ESV than the elective group at 7-10\u2009d postoperatively; and EDV, ESV, and LVEF improved in both groups after 3 months, while EDV, ESV, and LVEF improved significantly better in the emergency group than in the elective group, and the difference was statistically significant (\n                    <jats:inline-formula>\n                      <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.05<\/a:mn>\n                      <\/a:math>\n                    <\/jats:inline-formula>\n                    ). The myocardial infarct quality, VSM score, and ventricular wall motion abnormality score were significantly lower in the emergency group than in the elective group from 7 to 10\u2009d after PCI; myocardial infarct quality, VSM score, and ventricular wall motion abnormality score improved in both groups at 3 months after PCI; and the degree of improvement of myocardial infarct quality and VSM score was significantly better in the emergency group than in the elective group (\n                    <jats:inline-formula>\n                      <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.05<\/c:mn>\n                      <\/c:math>\n                    <\/jats:inline-formula>\n                    ). Conclusion. Acute myocardial infarction patients with significant effect of emergency PCI treatment can be on their postmyocardial infarction left ventricular function, and in the treatment of coronary heart disease, myocardial infarction diagnosis has a certain reference value.\n                  <\/jats:p>","DOI":"10.1155\/2022\/5629763","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T14:05:30Z","timestamp":1657029930000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["Cardiac Magnetic Resonance Assessment of the Protective Effect of Remote Ischemic Postconditioning on Coronary Microcirculation after Reperfusion Therapy for Acute ST-Segment Elevation Myocardial Infarction"],"prefix":"10.1155","volume":"2022","author":[{"given":"Chun","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Gerontology, Shibei Hospital of Jing\u2019an District, Shanghai 200443, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyong","family":"Duan","sequence":"additional","affiliation":[{"name":"Department of Gerontology, Zhongshan Hospital Wusong Branch, Fudan University\/Shanghai Baoshan District Wusong Central Hospital, Shanghai 200940, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9567-5649","authenticated-orcid":true,"given":"Jin","family":"Shu","sequence":"additional","affiliation":[{"name":"Department of Gerontology, Shibei Hospital of Jing\u2019an District, Shanghai 200443, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yajuan","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Gerontology, Shibei Hospital of Jing\u2019an District, Shanghai 200443, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1714\/3207.31839.PMID"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1159\/000509100"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000351"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-94311-4"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinimag.2020.04.024"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ihj.2019.12.003"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s11886-014-0557-5"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.5603\/KP.a2016.0098"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.3760\/cma.j.issn.0253-3758.2010.08.002"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3760\/cma.j.issn.0253-3758.2016.05.006"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.tcm.2018.09.004"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2020.10.062"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1093\/ehjacc\/zuab049"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1097\/MCC.0000000000000835"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.2174\/1573403X16999201210195702"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1186\/1475-925X-14-S2-S7"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.7861\/clinmed.20-2-s6"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9061997"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.2174\/1573405614666180815115756"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2020.109251.Epub"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.3889\/oamjms.2018.270"},{"issue":"2","key":"22","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1002\/mdc3.13070","article-title":"Conventional magnetic resonance imaging in the diagnosis of Parkinsonian disorders: a meta-analysis","volume":"8","author":"W.
