Rapid identification of high\u2010risk patients and subsequent provision of multidisciplinary care are critical. However, traditional risk scores mainly rely on infarct size, age, and hemodynamics, which may offer limited discriminatory ability at the time of hospital arrival. We developed a quick Forrester classification (QFC) using the respiratory rate (RR) and serum lactate levels upon hospital arrival and investigated its association with a reduced LVEF of patients with STEMI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study included consecutive patients with STEMI from 2018 to 2023. Patients were divided into four QFC classes: Class\u20101 (RR\u2009&lt;\u200920 per minute and lactate &lt;\u20092.0\u2009mmol\/L), Class\u20102 (RR\u2009\u2265\u200920 per minute and lactate &lt;\u20092.0\u2009mmol\/L), Class\u20103 (RR\u2009&lt;\u200920 per minute and lactate \u2265\u20092.0\u2009mmol\/L), and Class\u20104 (RR\u2009\u2265\u200920 per minute and lactate \u2265\u20092.0\u2009mmol\/L). The primary endpoint was the LVEF &lt;\u200945% measured by transthoracic echocardiography before discharge.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 569 patients with STEMI (Class\u20101: 118; Class\u20102: 146; Class\u20103: 92; Class\u20104: 213), the QFC Class\u20104 demonstrated the highest proportions of reduced LVEF (26%) and mechanical circulatory support use (13%). In multivariable logistic analysis, Class\u20104 was independently associated with reduced LVEF compared with Class\u20101 (odds ratio 2.47).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      The QFC, based solely on RR and lactate levels, was significantly associated with reduced LVEF in STEMI.
