Redox state of human serum albumin as a post-discharge prognostic marker in patients hospitalized for heart failure.

Background: Heart failure (HF) is a global health concern, and oxidative stress has been implicated in its progression. The redox state of human serum albumin, a systemic oxidative biomarker, holds promise as a prognostic marker in HF. This study aimed to investigate the association between the fraction of human mercaptalbumin (fHMA), an indicator of human serum albumin's redox state, and adverse events in HF within a prospective single-hospital-based cohort.

Association of Redox State of Human Serum Albumin with Severity in Patients with Heart Failure.

Oxidative stress plays a crucial role in the progression of heart failure (HF). We surveyed the fraction of human mercaptalbumin [f (HMA) ], an indicator of the redox state of human serum albumin (HSA), in patients with HF and examined whether f (HMA) is associated with the severity of HF.We enrolled consecutive elderly patients hospitalized for acute HF or exacerbation of HF.
