For a duration of 12 weeks, FJHQG will be administered to the intervention group, and the control group will receive standard therapy plus placebo. The primary outcome of the trial is the changes of six-minute walk test at week 24. Secondary outcomes include BNP levels, NYHA classification, major adverse cardiovascular events (MACE), and KCCQ quality of life scales. Other exploratory assessments at the beginning and after a 12-week period will include fluid balance, symptom score scales, echocardiograms, diuretic consumption, and biochemical indices. Monitoring of MACE will continue until 12 weeks after drug discontinuation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
