研究目的: |
本研究旨在通过随机、双盲、安慰剂对照试验,评估双歧杆菌四联活菌对射血分数保留型心力衰竭(HFpEF)患者的疗效与安全性,炎症反应及生活质量的变化,为益生菌在HFpEF中的临床应用提供循证医学依据。 |

|
Objectives of Study: |
This study aims to evaluate the efficacy and safety of quadruple live Bifidobacterium in patients with heart failure with preserved ejection fraction (HFpEF) through a randomized, double-blind, placebo-controlled trial. The study will focus on cardiac function, inflammatory responses, and quality of life after intervention, thereby providing clinical evidence for the use of probiotics in HFpEF. |
