Despite emergency percutaneous coronary intervention (PCI), in-hospital heart failure (HF) remains an important complication. This study aimed to identify factors independently associated with new-onset in-hospital HF and to develop an internally validated prediction model in patients with T2DM and STEMI undergoing emergency PCI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective observational study included 306 adult patients with T2DM and STEMI who underwent emergency PCI at the People\u2019s Hospital of Xinjiang Uygur Autonomous Region between January 2022 and February 2026. Patients were classified into HF (n=65) and non-HF (n=241) groups according to new-onset clinically documented HF during the index hospitalization; all patients classified as having HF had a maximum Killip class \u2265 II. Natriuretic peptides and echocardiographic findings were used as supportive evidence and were not included as predictors. Clinical, laboratory, echocardiographic, and selected procedural variables were analyzed using univariate and multivariable binary logistic regression. Model performance was assessed using discrimination, calibration, 10-fold cross-validation, and bootstrap optimism correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Independent positive associations with in-hospital HF were observed for prior myocardial infarction (OR\u00a0=\u00a06.205, 95% CI: 2.692\u201314.299, P&amp;lt;0.001), smoking (OR\u00a0=\u00a05.552, 95% CI: 2.517\u201312.247, P&amp;lt;0.001), regional wall motion abnormalities (OR\u00a0=\u00a02.415, 95% CI: 1.091\u20135.344, P\u00a0=\u00a00.030), higher white blood cell count (OR\u00a0=\u00a01.143 per 10\n                      <jats:sup>9<\/jats:sup>\n                      \/L, 95% CI: 1.072\u20131.219, P&amp;lt;0.001), higher systolic blood pressure (OR\u00a0=\u00a01.018 per mmHg, 95% CI: 1.001\u20131.034, P\u00a0=\u00a00.032), and age \u226575 years (OR\u00a0=\u00a04.792, 95% CI: 1.394\u201316.472, P\u00a0=\u00a00.013).
