T wenty-five years ago, the understanding of heart failure (HF) was straightforward. HF was a clinical syndrome due to left ventricular (LV) systolic dysfunction apparent as a reduced ejection fraction (EF). Based on this understanding , large randomized trials were conducted using an EF<0.30 or 0.35 as a key entry criterion. These studies demonstrated that the use of angiotensin-converting enz...

Current guidelines for the management of heart failure (HF) divide patients with HF into 2 categories: those with reduced ejection fraction (EF of ≤40%; HFrEF) and those with preserved ejection fraction (>40%; HFpEF). It has been recognized that a subset of patients with HFpEF previously had HFrEF. These patients with recovery or improvement in EF (HFiEF) may be clinically distinct from those w...

The electro-Fenton (EF) process is a powerful electrochemical advanced oxidation process. Its development has progressed over the past three decades as clean and effective technique for wastewater treatment. Even though conventional EF been shown to be efficient degradation/mineralization of toxic and/or persistent organic pollutants; it still suffers from some downsides industrial-scale develo...

tuberculosis (tb) and tobacco use are two major alarming global health issues posing immense threats to human populations. mycobacterium tuberculosis (mtb) by activation of macrophages could induce the sequences of cells activation and releases of inflammatory cytokines such as cxcl-8, il-12 and tnf-α which in turn induces the immune system network. however no information is available on other ...

Introduction: Perchloroethylene (PCE) is one of the most well-known chlorinated organic compounds recently detected in aqueous environments. The presence of PCE in aquatic ecosystems has caused many health problems and environmental challenges. Therefore, its removal and treatment from aqueous environments are essential. Materials and Methods: The electro-Fenton (EF) process was carried out in...

BACKGROUND The purpose of the current study was to define exercise-induced changes in indices of left ventricular (LV) systolic and diastolic properties in patients with chronic heart failure (HF), compare these changes in patients with HF and a reduced ejection fraction (EF) versus HF and a preserved EF, and compare the hemodynamic responses to activities of daily living with symptom-limited u...

AIMS Heart failure patients with reduced and preserved left ventricular (LV) ejection fraction (EF) show reduced exercise capacity. We explored the relationship between exercise capacity and systolic and diastolic myocardial function in heart failure patients. METHODS AND RESULTS Exercise capacity, by peak oxygen uptake (VO2), was assessed in 100 patients (56 ± 12 years, NYHA functional class...

BACKGROUND AND PURPOSE WARCEF randomized 2,305 patients in sinus rhythm with ejection fraction (EF) ≤ 35% to warfarin (INR 2.0-3.5) or aspirin 325 mg. Warfarin reduced the incident ischemic stroke (IIS) hazard rate by 48% over aspirin in a secondary analysis. The IIS rate in heart failure (HF) is too low to warrant routine anticoagulation but epidemiologic studies show that prior stroke increas...

AIMS The independent clinical correlates and prognostic impact of QRS prolongation in heart failure (HF) with reduced and preserved ejection fraction (EF) are poorly understood. The rationale for cardiac resynchronization therapy (CRT) in preserved EF is unknown. The aim was to determine the prevalence of, correlates with, and prognostic impact of QRS prolongation in HF with reduced and preserv...
