Introduction: Redox imbalance and oxidative stress are involved in the pathogenesis of
arrhythmias. They also play a significant role in pathogenesis of heart failure (HF). In …

Background Oxidative stress has been linked to heart failure (HF) in humans. Antioxidant-
based treatments are often ineffective. Therefore, we hypothesize that some of the HF …

Systolic and diastolic myocardial dysfunction has been demonstrated to be associated with
an activation of the circulating and local renin–angiotensin–aldosterone system (RAAS), and …

Heart failure (HF) is a major health problem, causing significant morbidity and mortality. Its
complex pathophysiology has not yet been fully elucidated. There is growing evidence that …

Background: The aim of the study was to assess changes of substances of oxidative stress
in patients treated with cardiac resynchronization therapy (CRT). Methods: The study …

Aims: Redox homeostasis is tightly controlled and regulates key cellular signaling pathways.
The cell's antioxidant response provides a natural defense against oxidative stress, but …

Oxidative stress (OS) is a keystone in the pathology of the ischemia reperfusion sequence
(acute coronary syndromes, cardiac surgery, transplantation). In heart failure, the implication …

Objective: It was the aim of this study to investigate the serum oxidative stress level in
nonischemic patients with heart failure (HF). Subjects and Methods: The study included 37 …

Regardless of the progress in therapeutic drugs and devices to treat heart failure (HF) during
the last few years, the clinical outcome of this disease remains deleterious. Impaired left …

Introduction: There is experimental evidence that heart failure (HF) is an oxidative stress and
that HF myocytes may be damaged by oxygen‐derived free radicals. However, the …
