The aim of this study was to assess the incidence of in-hospital myocardial infarction and\/or myocardial injury in patients undergoing hip fracture surgery and their association with mortality. Moreover, we evaluated the prognostic value of troponin increase stratified on the basis of peak troponin value. The electronic records of 1970 consecutive hip fracture patients were reviewed. Patients &lt;70 years, those with myocardial infarction &lt;30 days, and those with sepsis or active cancer were excluded from the study. Troponin and ECG were obtained at admission and then at 12, 24, and 48 h after surgery. Echocardiography was made before and within 48 h after surgery. Myocardial injury was defined by peak troponin I levels &gt; 99th percentile. A total of 1854 patients were included. An elevated troponin concentration was observed in 754 (40.7%) patients in the study population. Evidence of myocardial ischemia, fulfilling diagnosis of myocardial infarction, was found in 433 (57%). ECG and echo abnormalities were more frequent in patients with higher troponin values; however, mortality did not differ between patients with and without evidence of ischemia. Peak troponin was between 0.1 and 1 \u00b5g\/L in 593 (30.3%). A total of 191 (10%) had peak troponin I \u2265 1 \u00b5g\/L, and 98 died in hospital (5%). Mortality was significantly higher in both groups with troponin increase (HR = 1.37, 95% CI 1.1\u20131.7, p &lt; 0.001 for peak troponin I between 0.1 and 1 \u00b5g\/L; HR = 2.28, 95% CI 1.72\u20133.02, p &lt; 0.0001 for peak troponin \u22651 \u00b5g\/L) in comparison to patients without myocardial injury. Male gender, history of coronary heart disease, heart failure, and chronic kidney disease were also associated with in-hospital mortality. Myocardial injury\/infarction is associated with increased mortality after hip fracture surgery. Elevated troponin values, but not ischemic changes, are related to early worse outcome.<\/jats:p>","DOI":"10.3390\/jcm9124043","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T22:30:52Z","timestamp":1607985052000},"page":"4043","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Perioperative Myocardial Infarction\/Myocardial Injury Is Associated with High Hospital Mortality in Elderly Patients Undergoing Hip Fracture Surgery"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7764-8919","authenticated-orcid":false,"given":"Carlo","family":"Rostagno","sequence":"first","affiliation":[{"name":"SODc Medicina Interna e Post-Chirurgica, AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Cartei","sequence":"additional","affiliation":[{"name":"SODc Medicina Interna e Post-Chirurgica, AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaia","family":"Rubbieri","sequence":"additional","affiliation":[{"name":"SODc Medicina Interna e Post-Chirurgica, AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice","family":"Ceccofiglio","sequence":"additional","affiliation":[{"name":"SODc Medicina Interna e Post-Chirurgica, AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agnese","family":"Magni","sequence":"additional","affiliation":[{"name":"SODc Medicina Interna e Post-Chirurgica, AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Forni","sequence":"additional","affiliation":[{"name":"Agenzia Regionale Sanit\u00e0, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Civinini","sequence":"additional","affiliation":[{"name":"SOD Ortopedia e Traumatologia AOU Careggi, 50136 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Boccaccini","sequence":"additional","affiliation":[{"name":"SOD Anestesia e Rianimazione AOU Careggi, 50135 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1221","DOI":"10.1161\/CIRCULATIONAHA.117.030114","article-title":"Perioperative Myocardial Injury After Non-cardiac Surgery: Incidence, Mortality, and Characterization","volume":"137","author":"Puelacher","year":"2018","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2264","DOI":"10.1161\/CIRCULATIONAHA.113.002128","article-title":"Myocardial injury after noncardiac surgery and its association with short-term mortality","volume":"127","author":"Nathoe","year":"2013","journal-title":"Circulation"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"523","DOI":"10.7326\/0003-4819-154-8-201104190-00003","article-title":"Characteristics and short-term prognosis of perioperative myocardial infarction in patients undergoing noncardiac surgery: A cohort study","volume":"154","author":"Devereaux","year":"2011","journal-title":"Ann.
