Abstract:〔Abstract〕 Objective To investigate the efficacy and safety of Qiliqiangxin capsule combined with Canagliflozin in the treatment of chronic heart failure with Qi deficiency and blood stasis syndrome combined with type 2 diabetes mellitus. Methods 56 patients with chronic heart failure with Qi deficiency and blood stasis syndrome combined with Type 2 diabetes, treated by the First Affiliated Hospital of Henan University from January 2022 to June 2022, were given Qiliqiangxin capsule combined with Canagliflozin. Fasting blood glucose (FBG), glycated hemoglobin (HbA1c), left ventricular end-diastolic inner diameter (LVEDD), left ventricular ejection fraction (LVEF), Tei index, creatine kinase isoenzyme MB (CK–MB), hypersensitive cardiac troponin I (hs–cTnI) and N-terminal pro-B type natriuretic peptide (NT–proBNP), soluble tumor growth inhibitory factor 2 (sST2) and matrix metalloproteinase 2 (MMP–2) were compared before and after treatment. Results After treatment, the levels of FBG, HbA1c, LVEDD and Tei indexes were lower than those before treatment, while LVEF was higher than that before treatment, the differences were statistically significant (P < 0.05). After treatment, the levels of CK–MB, hs–cTnI, NT–proBNP, sST2, MMP–2 were lower than those before treatment, and the differences were statistically significant (P < 0.05). After treatment, the scores of patients in the physical field, emotional field and other fields were lower than those before treatment, and the differences were statistically significant (P < 0.05). Conclusion Qiliqiangxin capsule combined with Canagliflozin is effective and safe for treatment of chronic heart failure with Qi deficiency and blood stasis syndrome combined with type 2 diabetes, which improves FBG, HbA1c, cardiac function, heart failure markers and quality of life.
