The primary outcome was incidence of MACE. Univariaable and multivariaable logistic regression analyses were performed, followed by internal validation of the final multivariable model using bootstrap resampling. A nomogram, calibration plots, and decision curve analysis (DCA) were used to evaluate model performance and clinical utility. It is noteworthy that heart failure events were identified based on the documented clinical diagnosis made by the treating physician after comprehensive assessment of symptoms, signs, medical history, and available investigations. Although BNP measurements and echocardiographic assessments were not available for all patients, their absence did not preclude a clinical diagnosis of heart failure in routine practice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The incidence of total MACE increased progressively across RHR tertiles (T1: 20.5%, T2: 38.0%, T3: 52.6%;\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001). In the multivariable model, higher RHR (T2: odds ratio [OR]\u202f=\u202f2.09; T3: OR\u202f=\u202f4.70), higher Hospital Anxiety and Depression Scale (HADS) score (8\u201310: OR\u202f=\u202f6.40; &amp;gt;10: OR\u202f=\u202f2.04), diabetes (OR\u202f=\u202f6.52), elevated intact parathyroid hormone (iPTH) (OR\u202f=\u202f1.001), and lower uric acid (OR\u202f=\u202f0.74) were identified as independent predictors of total MACE. The nomogram demonstrated good discrimination (area under the curve [AUC]\u202f=\u202f0.820, specificity\u202f=\u202f0.843, and sensitivity\u202f=\u202f0.652), with good calibration and potential clinical utility demonstrated by calibration plots and DCA.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this single-center cohort of patients receiving maintenance hemodialysis, elevated RHR was independently associated with an increased risk of MACE after adjustment for psychosocial and metabolic factors, including HADS score, diabetes, uric acid, and iPTH. Incorporating RHR and these clinical variables into a risk model may facilitate early identification of high-risk patients for targeted intervention, although external validation is required before
