OBJECTIVE: To study the traditional Chinese medicine (TCM) syndromes of patients with chronic heart failure (CHF) combined with diuretic resistance by using the Wenyang Huayin Yangxin Prescription, and to observe its therapeutic efficacy. METHODS: A total of 68 CHF patients complicated with diuretic resistance and who had Yangqi deficiency and presenting blood stasis syndrome combined with Tanyin were randomly assigned to a control group and an observation group. The control group was given intravenous furosemide (≥ 80 mg/d) via infusion pump in addition to standard Western medical treatment, while the observation group was given intravenous furosemide (<
80 mg/d) via infusion pump along with the Wenyang Huayin Yangxin Prescription (30 g Astragalus, 15 g Poria, 15 g Baizhu, 15 g Chuanxiong, 10 g Danfu tablet, 10 g Cassia, 10 g Alisma, and 10 g Zhimu). The quantitative index of diuretic resistance was used as the primary outcome measure. In addition, the differences between the two groups in TCM syndromes, cardiac function-related indicators, incidence of endpoint events, and readmission rate were compared. RESULTS: After 2 weeks of treatment, the filtration sodium excretion fraction (FENa) in the observation group was (0.18 ± 0.04)%, while that of the control group was (0.16 ± 0.03)%, showing a statistically significant difference ( CONCLUSION: The Wenyang Huayin Yangxin Prescription, combined with low-dose intravenous furosemide administered through an infusion pump, can improve the TCM syndromes of patients with Yangqi deficiency and blood stasis syndrome combined with Tanyin in addition to CHF complicated by diuretic resistance. This treatment improves the patients' heart function and diuretic resistance, reduces the intravenous dosage of diuretic, and enhances clinical efficacy. This approach should be more widely applied in clinical settings.
