Impact of Lactobacillus Plantarum 299v Probiotic Supplementation on Vascular Function and Exercise Capacity in Chronic Heart Failure With Reduced and Preserved Ejection Fraction.
The goal of this study is to determine the impact of 12 weeks of Lp299v supplementation (20 million cfu/day vs. placebo) on exercise capacity, circulating biomarkers of cardiac remodeling, quality of life, and vascular endothelial function in humans with heart failure and reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) who have evidence of residual inflammation based on an elevated C-reactive protein level. This will be done in the setting of a randomized, double-blind, placebo-controlled trial.
• Age between 21-89 years old
• Clinical diagnosis of Congestive Heart Failure (CHF) in the six months prior to enrollment along with an echocardiogram documenting systolic dysfunction with ejection fraction ≤40%
• Clinical diagnosis of CHF in the six months prior to enrollment along with an echocardiogram documenting diastolic dysfunction with an ejection fraction ≥50%, and a H2FpEFF score of ≥6
• New York Heart Association (NYHA) Class II-IIID heart failure symptoms with either ischemic or non-ischemic etiology OR similar diagnosis with congestive heart failure (CHF) along with an echocardiogram documenting an LV ejection fraction of 50% or more with similar NYHA classification as those with LVEF of 40% or less
• Evidence of systemic inflammation at baseline (C-reactive protein ≥ 2 mg/L at the time of screening)
