Heart failure is a serious condition where the heart cannot pump blood well enough. Many people live with this daily, facing shortness of breath and fatigue. Standard Western medicine helps, but doctors often wonder if there is more to offer. A new systematic review and network meta-analysis looked at adding oral traditional Chinese medicines containing Astragalus to standard Western medicine. This research involved 1584 patients with heart failure. The goal was simple: did adding these herbal treatments help patients feel better or live longer compared to Western medicine alone? The answer appears to be yes, but the specific medicine matters for different goals.
The researchers analyzed many studies to compare different herbal options. They found that Astragalus Granule combined with Western medicine ranked best for the overall clinical efficacy rate. This means the general success of the treatment was highest with this specific combination. For patients trying to walk further without getting tired, the six-minute walk test showed that Qiangxin Capsule combined with Western medicine was the optimal choice. This test measures how far a person can walk in six minutes, a common way to track heart health.
Other heart health markers also improved with these additions. B-type natriuretic peptide levels, which rise when the heart is under stress, were reduced best by Astragalus Granule combined with Western medicine. Yanxing Decoction combined with Western medicine ranked first for lowering N-terminal pro-B-type natriuretic peptide levels. These are similar stress markers that doctors track to see if the heart is calming down. For improving the left ventricular ejection fraction, which measures how much blood the heart pumps out with each beat, Xinlishen Compound combined with Western medicine was the optimal combination. This helps the heart pump more strongly.
Safety was a major concern for the researchers. The review noted that no adverse events, serious adverse events, discontinuations, or tolerability issues were reported in the included studies. This suggests these medicines are well-tolerated when taken alongside standard care. Additionally, the study looked at left ventricular end-diastolic diameter, which measures the size of the heart chamber. Qili Qiangxin Capsule combined with Western medicine performed best for reducing this size. Finally, Yangxin Tongmai II Prescription combined with Western medicine showed the highest efficacy for decreasing Minnesota Heart Failure Quality of Life Questionnaire scores. Lower scores on this questionnaire mean better quality of life for the patient.
Despite these positive results, there are important caveats. The limitations of the research include a limited number and quality of the included studies. This means the conclusions still require further validation through well-designed randomized double-blind controlled trials. Because the evidence is not yet perfect, people should not overstate what this single review proves. The certainty of the findings is limited by the quality of the original studies. Doctors should wait for more robust trials before changing standard protocols based on this data alone.
What does this mean for patients right now? Adding oral traditional Chinese medicine containing Astragalus to Western medicine treatment can further improve the clinical efficacy of heart failure. This offers a potential new path for patients who want to explore complementary options. However, patients must talk to their doctors before adding any new medicine. The specific type of medicine matters, as different herbs worked best for different outcomes. This review provides a map of which options might help, but it is not a final verdict. The journey to better heart health is complex, and more research is needed to confirm these benefits for everyone.
