The present study evaluated the prognostic value of 24 h high-sensitivity cardiac troponin I (hs-Troponin I) and assessed whether combining biomarkers and echocardiographic parameters improves short-term risk prediction. Methods: This prospective observational cohort study included 170 consecutive adult patients with confirmed NSTEMI who were admitted to a Medical Intensive Care Unit and prospectively enrolled between February 2022 and January 2023. Clinical, routine biochemical, inflammatory, hematological, lipid, and echocardiographic data were collected during index hospitalization. High-sensitivity cardiac troponin I was measured at admission and again 24 h after hospitalization, with the 24 h value used as the principal marker of myocardial injury in the prediction analyses. The primary endpoint was major adverse cardiovascular events (MACEs), defined as cardiovascular death, recurrent myocardial infarction, ischemic stroke, urgent coronary revascularization, or hospitalization for worsening heart failure, within 3 months. Multivariable logistic regression, Cox regression, sequential prediction modeling, and internal bootstrap validation were performed. Results: MACEs occurred in 88 patients (51.8%). Twenty-four-hour hs-Troponin I, but not admission hs-Troponin I, was independently associated with MACEs (OR 1.57, 95% CI 1.09\u20132.26; p = 0.015) and a shorter time to the first MACE event (HR 1.38, 95% CI 1.07\u20131.78; p = 0.012). Lower left ventricular ejection fraction (LVEF) was also independently associated with adverse outcomes. The addition of 24 h hs-Troponin I, LVEF, and C-reactive protein improved discrimination from an AUC of 0.665 to 0.759 (optimism-corrected AUC, 0.717), with corresponding improvements in reclassification. A simplified multimarker score was independently associated with event-free survival (HR 2.36, 95% CI 1.53\u20133.64; p &lt; 0.001). Conclusions: In patients admitted to a medical intensive care unit with NSTEMI, the integration of 24 h hs-Troponin I, LVEF, and C-reactive protein improved short-term risk prediction beyond that of clinical variables alone. A practical multimarker model based on routinely available parameters identified patients at increased risk of adverse cardiovascular outcomes during early follow-up.<\/jats:p>","DOI":"10.3390\/clinpract16080143","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T08:02:19Z","timestamp":1785830539000},"page":"143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Multidomain Prediction Model Integrating Myocardial Injury, Ventricular Function, and Inflammation for Short-Term Risk Stratification in Patients with NSTEMI"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4134-987X","authenticated-orcid":false,"given":"Emir","family":"Be\u0107irovi\u0107","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, University Clinical Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4391-5226","authenticated-orcid":false,"given":"Minela","family":"Be\u0107irovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University Clinical Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7012-8064","authenticated-orcid":false,"given":"Amir","family":"Be\u0107irovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, University Clinical Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4075-3790","authenticated-orcid":false,"given":"Amir","family":"Tursunovi\u0107","sequence":"additional","affiliation":[{"name":"Department of General and Abdominal Surgery, University Clinical Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajla","family":"Bajri\u0107","sequence":"additional","affiliation":[{"name":"Primary Health Care Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7583-1490","authenticated-orcid":false,"given":"Amil","family":"Softi\u0107","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, University Clinical Center Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4865-8239","authenticated-orcid":false,"given":"Adna","family":"Mujki\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7854-0973","authenticated-orcid":false,"given":"Elma","family":"Mujakovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Tuzla, 75000 Tuzla, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3999-6521","authenticated-orcid":false,"given":"Admir","family":"Abdi\u0107","sequence":"additional","affiliation":[{"name":"Department of Abdominal Surgery, Cantonal Hospital Biha\u0107, 77000\u00a0Biha\u0107, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1728-0649","authenticated-orcid":false,"given":"Lamija","family":"Ferhatbegovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Cantonal Hospital Zenica, 72000 Zenica, Bosnia and Herzegovina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e023645","DOI":"10.1161\/JAHA.121.023645","article-title":"Non-ST-segment-elevation myocardial infarction: When is rapid revascularization critical?","volume":"10","author":"Case","year":"2021","journal-title":"J.
