Background Diuretic resistance is associated with increased mortality in patients with heart failure (HF). Qi Li Qiang Xin Jiao Nang, a Traditional Chinese Medicine, are used in the treatment of HF. However, clinical evidence of their effectiveness in improving diuretic resistance is lacking. Objective To investigate whether Qi Li Qiang Xin Jiao Nang can reduce the risk of diuretic resistance and improve prognosis in patients with acute decompensated chronic heart failure (ADCHF) . Methods This study included 374 HF patients treated in the CICU ward of Tianjin University Chest Hospital from January 2018 to June 2022. Patients were divided into diuretic resistance (118 patients) and non-diuretic resistance groups (256 patients) based on the occurrence of diuretic resistance. Patient data and laboratory results were collected. A 12-month follow-up was conducted to observe rehospitalization due to cardiovascular events or all-cause mortality. Kaplan-Meyer survival curves were plotted for each group, and the Log-rank test was used for comparison. Multivariate Logistic regression analysis was performed to explore factors influencing diuretic resistance. Multivariable Cox regression analysis was used to explore factors affecting the occurrence of endpoint events in ADCHF patients. Results The diuretic resistance group showed higher age, body mass, NT-proBNP, blood urea nitrogen, creatinine, uric acid, and international normalized ratio (INR) but lower 24-hour fluid intake, estimated glomerular filtration rate (eGFR), lymphocyte count, and usage of Qi Li Qiang Xin Jiao Nang. Multivariate Logistic regression analysis indicated that the use of Qi Li Qiang Xin Jiao Nang (OR=0.363, 95%CI=0.186-0.708, P=0.003) and increased 24-hour fluid intake (OR=0.286, 95%CI=0.177-0.461, P |
