Improvement of exercise tolerance and physical function in elderly patients with heart failure with preserved ejection fraction by QiShen YiQi dripping pills

The combination of QSYQ dripping pills with standard therapy may yield limited improvements in exercise tolerance, physical function, and quality of life for elderly patients with HFpEF, and may potentially mitigate left atrial remodeling. However, given the sample size and design limitations of this study, these findings are exploratory. Their precise clinical value and long-term safety require validation through further large-scale studies.
