Key Finding
QSYQ formula improved heart failure outcomes in mice by restoring myocardial energy metabolism through AMPK pathway activation, increasing ATP production while reducing oxidative stress and improving cardiac function.
Researchers investigated a traditional Chinese herbal formula called Qishenyiqi (QSYQ) to see if it could help treat heart failure, a serious condition where the heart cannot pump blood effectively. Heart failure is often linked to problems with how the heart muscle produces and uses energy. The study used mice with surgically induced heart failure and treated them with QSYQ for four weeks. The researchers found that QSYQ significantly improved heart function, reducing heart enlargement and scarring (fibrosis) while improving the heart's pumping ability. Most importantly, the formula helped restore the heart's energy production by fixing problems in the mitochondria—the tiny power plants inside cells. Using advanced analysis techniques, scientists discovered that QSYQ works by activating a key energy regulator called AMPK, which then helps the heart better process both glucose and fatty acids for fuel. The treatment also reduced harmful oxidative stress and increased ATP production, the main energy currency of cells. This study provides scientific evidence for how traditional Chinese herbal medicine can address the underlying metabolic problems in heart failure, not just the symptoms. While this research was conducted in animals and focused on herbal formulas rather than acupuncture specifically, it demonstrates how traditional Chinese medicine approaches may complement conventional heart failure treatments.

This preclinical study examined Qishenyiqi formula's (QSYQ) mechanisms in transverse aortic constriction (TAC)-induced heart failure using multi-omics analysis. Mice received QSYQ (1170 or 585 mg/kg) or vehicle for four weeks post-TAC surgery. QSYQ treatment significantly improved ejection fraction, reduced cardiac hypertrophy and fibrosis, and decreased ANP/BNP biomarkers. Transmission electron microscopy revealed restored mitochondrial ultrastructure, while functional assays demonstrated increased ATP synthesis, reduced ROS production, and stabilized membrane potential. Integrated proteomics and metabolomics identified AMPK pathway activation as the primary mechanism, with downstream upregulation of PPARα and PGC-1α mediating improved glucose and fatty acid metabolism. The study provides molecular evidence for QSYQ's cardioprotective effects through metabolic remodeling. Clinical translation requires human trials, but findings support traditional herbal formulas as adjunctive metabolic therapy in heart failure management, particularly for patients with metabolic dysfunction.
