Summary

This trial will study how a probiotic supplement affects exercise capacity, biomarkers, quality of life, and vascular function in people with HFrEF and inflammation.

Who is the study for?
This trial is for adults aged 21-89 with heart failure diagnosed in the last six months, having either reduced ejection fraction (≤40%) or preserved ejection fraction (≥50%) and inflammation indicated by high C-reactive protein levels. Excluded are those with severe valve disease, certain GI illnesses, pregnant women, recent antibiotic use, severe kidney/lung diseases, active infections or inflammatory diseases, cancer with low survival expectancy, liver failure, on blood thinners like Warfarin or taking Lactobacillus probiotics.
What is being tested?
The study tests if a probiotic called Lp299v can improve exercise capacity and quality of life over 12 weeks compared to a placebo in people with different types of heart failure. It's randomized and double-blind meaning neither participants nor researchers know who gets the real treatment versus placebo during the study.
What are the potential side effects?
Potential side effects from Lp299v may include digestive discomfort such as gas or bloating since it's a probiotic supplement. However specific side effects will be monitored throughout the trial given that this is an investigation into its safety and efficacy.
