The aim of this investigation is to evaluate the role of coronary calcification, detected by coronary angiography, in the whole spectrum of patients presenting with acute ACS.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>The present study was a post hoc analysis of the MATRIX programme. The primary endpoint was major adverse cardiovascular events (MACE), defined as the composite of all-cause mortality, myocardial infarction (MI), or stroke up to 365 days. Among the 8404 patients randomized in the MATRIX trial, data about coronary calcification were available in 7446 (88.6%) and therefore were included in this post hoc analysis. Overall, 875 patients (11.7%) presented with severe coronary calcification, while 6571 patients (88.3%) did not present severe coronary calcification on coronary angiography. Fewer patients with severe coronary calcification underwent percutaneous coronary intervention whereas coronary artery bypass grafting or medical therapy-only was more frequent compared with patients without severe calcification. At 1-year follow-up, MACE occurred in 237 (27.1%) patients with severe calcified coronary lesions and 985 (15%) patients without severe coronary calcified lesions [hazard ratio (HR) 1.91; 95% confidence interval (CI) 1.66\u20132.20, P &amp;lt; 0.001]. All-cause mortality was 8.6% in patients presenting with and 3.7% in those without severe coronary calcification (HR 2.38, 1.84\u20133.09, P &amp;lt; 0.001). Patients with severe coronary calcification incurred higher rate of MI (20.1% vs. 11.5%, HR 1.81; 95% CI 1.53\u20132.1, P &amp;lt; 0.001) and similar rate of stroke (0.8% vs. 0.6%, HR 1.35; 95% CI 0.61\u20133.02, P = 0.46).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Patients with ACS and severe coronary calcification, as compared to those without, are associated with worse clinical outcomes irrespective of the management strategy.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjacc\/zuad122","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T20:13:33Z","timestamp":1696882413000},"page":"782-791","source":"Crossref","is-referenced-by-count":7,"title":["Coronary calcification in patients presenting with acute coronary syndromes: insights from the MATRIX trial"],"prefix":"10.1093","volume":"12","author":[{"given":"Jorge","family":"Sanz-Sanchez","sequence":"first","affiliation":[{"name":"Cardiology Department, Hospital Universitari i Politecnic La Fe , Valencia , Spain"},{"name":"Centro de Investigaci\u00f3n Biomedica en Red (CIBERCV) , Madrid , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5100-0471","authenticated-orcid":false,"given":"Hector M","family":"Garcia-Garcia","sequence":"additional","affiliation":[{"name":"Interventional Cardiology, MedStar Washington Hospital Center , 10 Irving St NW, Washington, DC 2001 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mattia","family":"Branca","sequence":"additional","affiliation":[{"name":"CTU Bern, University of Bern , Bern , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico","family":"Frigoli","sequence":"additional","affiliation":[{"name":"CTU Bern, University of Bern , Bern , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio","family":"Leonardi","sequence":"additional","affiliation":[{"name":"Coronary Care Unit, Department of Molecular Medicine, University of Pavia and Fondazione IRCCS Policlinico San Matteo , Pavia , Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Gagnor","sequence":"additional","affiliation":[{"name":"Department of Invasive Cardiology, Maria Vittoria Hospital , Turin , Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Calabr\u00f2","sequence":"additional","affiliation":[{"name":"Division of Cardiology, \u2018Sant\u2019Anna e San Sebastiano\u2019 Hospital , Caserta , Italy"},{"name":"Department of Translational Medicine, University of Campania \u2018Luigi Vanvitelli\u2019 , Caserta , Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Garducci","sequence":"additional","affiliation":[{"name":"Cardiology Department, A.O.
