|Renal Insufficiency, Chronic Heart Failure With Preserved Ejection Fraction||Dietary Supplement: MitoQ Dietary Supplement: Placebo||Phase 4|
Heart failure is a public health epidemic affecting 6.5 million Americans. Heart failure with preserved ejection fraction (HFpEF) accounts for a large burden of heart failure with the incidence and cost associated with the disease projected to double in the next 20 years. The pathophysiology of HFpEF has not yet been fully elucidated and no proven therapies for improving outcomes in HFpEF currently exist, posing major diagnostic and therapeutic challenges. The addition of chronic kidney disease (CKD) presents a complicated cardio renal syndrome that manifests a distinctly different phenotype and exacerbates the diagnostic and therapeutic challenges of HFpEF. This study aims to address the urgent need to establish treatment targets and therapies by investigating potential underlying biological contributors to HFpEF and its symptoms.
Mitochondrial dysfunction is consistently reported in CKD and heart failure. Mitochondrial dysfunction has been implicated in cardiac, skeletal muscle and vascular dysfunction and is therefore an attractive target for a 'whole systems' therapeutic approach that would encompass exercise intolerance and abnormal blood vessel hemodynamics. A known contributor to and subsequent cyclical result of mitochondrial dysfunction is an abnormally heightened production of mitochondria derived oxidative stress. This study will address the role of mitochondria derived oxidative stress in mitochondrial dysfunction, exercise intolerance and large blood vessel hemodynamics HFpEF patients with and without CKD.
