Dynamic treatment regimens for congestive heart failure
… of patients are hospitalized with a diagnosis of congestive heart failure (CHF). This condition is characterized by inadequate tissue perfusion resulting from an inability of the heart to provide enough blood to meet the body's metabolic demands. Patients with CHF remain at a greater risk for …

Recognition of Severe Congestive Heart Failure using Parallel Cascade Identification
In previous studies on heartbeat series, it has been proposed that the healthy heartbeat pattern represents complex nonlinear dynamics, and such cardiac nonlinearity may be used as a clinical indicator for the diagnosis of certain types of heart disease. However, it is still not quite clear whether …

A portable bioimpedance spectroscopy system for congestive heart failure management
Congestive Heart Failure (CHF) is a chronic medical condition that causes reduced exercise tolerance, shortness of breath, and fluid buildup in the lungs, legs, and abdomen. While CHF-related mortality has reduced in recent years, this reduction has been accompanied by an increase in …

Objective Measurement of Peripheral Edema as Symptomatic of Congestive Heart Failure
Congestive heart failure is a type of cardiovascular disease that is often accompanied by excess fluid buildup in tissue, causing swelling of the extremities, known as peripheral edema. Assessing the severity level of pitting, or indentation, in peripheral edema can potentially provide insights …

Relationship of Ventilation Ability and Positioning in Left-Sided Congestive Heart Failure Patients
… used to relieve dyspnea, edema, and fatigue in congestive heart failure patients. According to the review of literature, improved ventilation as measured by specific lung volumes and lung mechanics occurred with upright positioning in normal persons. The effects of specific changes in lung …

Breathlessness Descriptors in Patients with Chronic Obstructive Pulmonary Disease Versus Congestive Heart Failure
… Chronic Obstructive Pulmonary Disease (COPD) and Congestive Heart Failure (CHF). The purpose of this study was (a) to characterize the most common terms COPD and CHF patients use to describe their breathing, (b) to identify the frequency of dyspnea in patients with COPD and CHF, and (c) to …

The effects of congestive heart failure and functional overload on rat skeletal muscle
… that alterations in exercise capacity during congestive heart failure (CHF) are not simply due to changes in myocardial function. In fact, recent evidence has indicated that reductions in skeletal muscle strength and endurance during CHF significantly impact exercise capacity of the CHF …

Fluid retention in congestive heart failure-the role of natriuretic peptides and arginine vasopressin
Fluid retention is associated with congestive heart failure (CHF). The role played by atrial natriuretic factor (ANF), brain natriuretic peptide (BNP), C-type natriuretic peptide (CNP) and arginine vasopressin (AVP) in CHF is not fully understood. Studies were done in 300days old male normal and …

Making medication adherence decisions: Stories from older adults taking medications for congestive heart failure
More than half of all CHF patients do not take medications as prescribed, resulting in substantial negative health outcomes. Research has shown that medication adherence may be more a consequence of individual decisions rather than the ability to follow prescribed regimens, yet very little is known …

Changes in Skeletal Muscle Sarcoplasmic Reticulum Calcium Handling and Regulatory Protein Content in Congestive Heart Failure
… muscle weakness are problems associated with congestive heart failure. Research does not support the theory that the affected cardiac function is responsible for the fatigue. During skeletal muscle fatigue, calcium handling is altered. Thus, the fatigue associated with congestive heart failure …

Clinical factors associated with Atrial Fibrillation in congestive Heart Failure patients admitted at the University Teaching Hospital, Lusaka, Zambia
Introduction: Atrial fibrillation (AF) and congestive heart failure (CHF) have emerged as major global epidemics. These two conditions share common risk factors and frequently coexist. Each condition predisposes to the other, and the concomitant presence of the two has additive adverse effects. …

Congestive Heart Failure Hospital Admissions among Non-Elderly Medicaid and Uninsured Working-Age Adult Patients in South Carolina, 2008
<p>Congestive Heart Failure Hospital Admissions among Non-Elderly Medicaid and Uninsured Patients in South Carolina, 2008.</p> <p>Background: Despite significant advances in the quality of care in some areas, hospital admissions for heart failure (HF) continue to rise . Data for this study examined …

IMPACT OF INDOOR AIR POLLUTION ON INFLAMMATORY BIOMARKERS AND CARDIAC AUTONOMIC CONTROL IN HEALTHY SUBJECTS AND PATIENTS WITH CONGESTIVE HEART FAILURE (APICE STUDY)
… subjects and patients affected by chronic heart failure (HF). Twenty healthy volunteers and nineteen HF patients were enrolled. Indoor levels of fine particulate matter (PM2.5), nitrogen dioxide (NO2) and volatile organic compounds (VOCs) were monitored using a portable detector for 7 days. …

Multifractal analysis of heart rate variability using wavelet-transform modulus-maxima method
… studies reveal that under normal conditions, the heart rate time series shows multifractal behavior. In contrast, HRV in the pathological state such as congestive heart failure exhibits more monofractal-like structure. Recent advances in the assessment of heart rate variability (HRV) uses a …

Wearable Heart Sound and EKG Recorder
<p>Acute congestive heart failure is a leading cause of morbidity and mortality. Patients often undergo repeated hospitalizations with an annual cost in excess of $32B dollars. Early detection of impending acute congestion allows for pharmaceutical interdiction that prevents hospitalization, …

Comparison of echocardiography and computed tomography for characterization of cardiac clots in cats with heart disease
… condition in cats most commonly secondary to heart disease. Echocardiography is the reference standard to evaluate for presence of a clot or its precursor known as spontaneous echocardiographic contrast (SEC or “smoke”) within the left atrium and left auricle. In humans, trans-esophageal …

Retention of best practices by clinicians after knowledge transfer
… of an integrated care pathway for patients with congestive heart failure. While the literature suggests there are many reasons why the implementation of best practices is difficult, there is little information on the sustainability of best practices once implemented.Using a qualitative research …

Increasing Self Care Compliance with Follow-up Appointments
<p>The congestive heart failure patient faces many challenges after discharge from the hospital. Learning how to manage diet, medications, and other lifestyle changes needed for symptom management can lead to multiple readmissions and rapid progression of condition. Many patients feel overwhelmed …
