Compound Astragalus Oral Liquid (CAOL) is a traditional Chinese medicine formulation with anti\u2010inflammatory, antioxidant, and tonifying properties. However, its effects and underlying mechanisms in post\u2010acute myocardial infarction heart failure (AMI\u2010HF) remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To evaluate the cardioprotective efficacy of CAOL in a rat model of AMI\u2010HF and elucidate the associated molecular mechanisms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>CAOL constituents were identified by UPLC\u2010Q\u2010TOF\/MS, and network pharmacology predicted potential targets. A rat model of AMI\u2010induced HF was established by left anterior descending (LAD) coronary ligation. Animals received CAOL at low, medium, and high doses, or perindopril. Cardiac function, histopathology, serum oxidative and inflammatory markers, and myocardial molecular expression were assessed by echocardiography, staining, ELISA, Western blotting, and RT\u2010qPCR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      CAOL treatment improved cardiac performance in a dose\u2010dependent manner, as evidenced by increased LVEF and improvements in LVIDd and LVIDs. Histological analyses demonstrated that CAOL reduced myocardial necrosis, inflammatory cell infiltration, and collagen deposition in a dose\u2010dependent fashion. CAOL also ameliorated serum markers of inflammation and oxidative stress.
