Abstract Heart failure with preserved ejection fraction (HFpEF) accounts for over 50% of all heart failure cases nationwide and continues to rise in its prevalence. The complex, multi‐organ involvement of the HFpEF clinical syndrome requires clinic

Systemic sclerosis (SSc) is a rare, auto-immune disease with variably progressive fibrosis of the skin and internal organs, as well as vascular dysfunction. Recently, we demonstrated a decrement in exercising skeletal muscle blood flow and endotheliu

Stimulation of α1-adrenergic receptors eliminated age-related differences in passive leg movement (PLM) by decreasing PLM-induced vasodilation in the young. Systemic β-blockade attenuated the central hemodynamic component of the PLM response in you

The current investigation has demonstrated that l-Cit administration may improve brachial artery endothelium-dependent vasodilation, upper and lower limb microvascular function, and physical capacity in patients with HFpEF, highlighting the potential

Exercise intolerance is a well-described characteristic of heart failure with preserved ejection fraction (HFpEF), but whether disease-related changes in autonomic function contribute to impaired cardiovascular control during exercise is not well und

Background: The arterial baroreflex (ABR) plays an important role in evoking appropriate cardiovascular adjustments in response to perturbations such as exercise. The ABR control of heart rate (HR) becomes attenuated with advancing age and in a varie

As a deficiency in tetrahydrobiopterin (BH(4)), a cofactor for endothelial nitric oxide synthase, has been implicated in the age-related decline in vascular function, this study aimed to determine the impact of acute BH(4) supplementation on flow-med

Obesity is now considered a primary comorbidity in heart failure with preserved ejection fraction (HFpEF) pathophysiology, mediated largely by systemic inflammation. Although there is accumulating evidence for a disease-related dysregulation of blood

Despite two different experimental approaches, acute BH4 supplementation did not affect vascular function in older adults, as measured by flow-mediated vasodilation. Plasma levels of both BH4 and BH2, the BH4 oxidized form, significantly increased af

While there is emerging evidence of peripheral microvascular dysfunction in patients with heart failure with preserved ejection fraction that may be related to systemic inflammation and redox imbalance, disease-related changes in locomotor muscle mic
