Chronic Heart Failure With Preserved Ejection Fraction
Conditions
Brief summary
Main objective: To evaluate the efficacy, safety and clinical dose exploration of Qishen Yiqi dripping pills in the treatment of chronic heart failure with preserved ejection fraction.
Detailed description
Main objective: To evaluate the efficacy, safety and clinical dose exploration of Qishen Yiqi dripping pills in the treatment of chronic heart failure with preserved ejection fraction. Exploratory research objective: To explore the changes of endogenous substances in vivo before and after drug administration, to interpret the mechanism of drug action through metabolomics and systems biology methods, and to find potential clinical biomarkers for exploratory subgroup analysis of clinical trials.

Exclusion criteria
* People with any of the following cardiovascular diseases: 1.
