- HEART FAILURE.
- What Is Heart Failure? Heart failure occurs when the heart is unable to pump sufficient blood to meet the body's demand. ... It is the combination of the initial heart damage plus the compensatory responses that results in heart failure. ...
- What Causes Heart Failure? The five most common causes of heart failure are coronary artery disease (due to atherosclerosis), valvular heart disease, high blood pressure, alcohol, and a disease of heart muscle known as dilated cardiomyopathy. Coronary artery disease accounts for 60 to 70% of all cases of heart failure. Each of these five conditions can cause heart failure by damaging heart muscle and therefore increasing the workload on the remainder of the heart. ...
- What Are The Signs And Symptoms Of Heart Failure? The signs and symptoms of heart failure are due to a backlog of pressure in the blood vessels as the heart is unable to maintain adequate forward flow. Consequently, heart failure is often termed congestive heart failure. ... If heart failure develops over time, the person will first experience trouble breathing upon exertion; as the disease progresses, the person may become short of breath at rest or during the night. ... Other symptoms of heart failure are dependent upon the original cause of damage to the heart. ...

- www.aafp.org
- Update on Digoxin Therapy in Congestive Heart Failure.
- Congestive heart failure is a progressive disease with significant morbidity and mortality. Despite advances in the prevention and treatment of cardiovascular diseases, the incidence and prevalence of congestive heart failure have increased in recent years. ... New and existing agents, including angiotensin-converting enzyme inhibitors, beta blockers and, more recently, spironolactone, are being used increasingly to prolong life in patients with heart failure. Although digoxin has been used to treat heart failure for more than 200 years, its role in patients with congestive heart failure and sinus rhythm is still debatable. ... In recent trials, digoxin has been shown to reduce morbidity associated with congestive heart failure but to have no demonstrable effect on survival. The goal of digoxin therapy in patients with congestive heart failure is to improve quality of life by reducing symptoms and preventing hospitalizations. ...
- Congestive heart failure has been recognized as a syndrome of anatomic, functional and biologic alterations that interact together in a complex manner over a prolonged period. ... Over time, however, physicians began to recognize that congestive heart failure was associated with reduced cardiac output and excessive peripheral vasoconstriction. ...
- Despite these therapeutic developments, it became apparent that at some point, congestive heart failure would progress independent of the patient's hemodynamic status. ... 1 According to this model, heart failure progresses as a result of overexpression of biologically active molecules that exert toxic effects on the heart and circulation. ...
- Patients with more severe heart failure, a third heart sound gallop, left ventricular enlargement and a depressed left ventricular ejection fraction are more likely to respond to digoxin therapy. ...
- The transition to symptomatic heart failure is accompanied by further activation of the neurohormonal system, including the sympathetic nervous system and a series of adaptive changes in the myocardium, collectively referred to as "left ventricular remodeling. ...
- Epidemiology of Congestive Heart Failure and Evolution of Treatment.
- Congestive heart failure continues to be a major health problem. Despite significant advances in the prevention and treatment of cardiovascular diseases, the incidence and prevalence of congestive heart failure have been increasing in recent years. ...

- www.jap.org
- Skeletal muscle mass and exercise performance in stable ambulatory patients with heart failure .
- Skeletal muscle mass and exercise performance in stable ambulatory patients with heart failure. ... The purpose of this study was to determine whether skeletal muscle atrophy limits the maximal exercise capacity of stable ambulatory patients with heart failure. Body composition and maximal exercise capacity were measured in 100 stable ambulatory patients with heart failure. ... These findings suggest that exercise intolerance in stable ambulatory patients with heart failure is not due to skeletal muscle atrophy. ...
- EXERCISE INTOLERANCE is a widespread clinical problem in patients with heart failure (4, 11, 26, 27). ... These findings have fueled speculation that skeletal muscle abnormalities are important and universal contributors to exercise intolerance in heart failure. ...
- It remains uncertain, however, whether skeletal muscle abnormalities occur in all patients with heart failure or primarily affect a relatively small subgroup of patients. There is little question that some patients with severe heart failure develop dramatic muscle wasting, a condition known as cardiac cachexia. It is far less clear whether ambulatory stable patients with heart failure develop muscle abnormalities. ...
- The purpose of the present study was to investigate the contribution of skeletal muscle atrophy to exercise intolerance in stable ambulatory patients with heart failure. To this end, we measured body composition in a large group of patients with heart failure using dual- energy X-ray absorption, a new technology that provides quantitative information about lean body mass, body fat content, and leg lean mass (10, 15, 19, 24). ...
- Studies were performed on 100 stable ambulatory patients followed by the Heart Failure and Heart Transplantation Program at Vanderbilt University Medical Center. All patients had a history of chronic heart failure for >6 mo, and all patients were ambulatory and receiving digoxin, an angiotensin-converting enzyme inhibitor, and diuretics. ... Heart failure was attributed to coronary arterial disease in 54 patients, to idiopathic cardiomyopathy in 42 patients, and to valvular heart disease in 4 patients. ...
- Body composition studies and maximal exercise testing were performed on all patients as part of standard clinical evaluation of their heart failure. ...

- www.heartjnl.com
- Nocturnal desaturation in patients with stable heart failure .
- ObjectiveTo determine the prevalence of sleep disordered breathing within a United Kingdom heart failure population.
- ConclusionsNocturnal desaturation is common in patients with treated heart failure. ... Lack of correlation between dips and ESS suggests that arousal from sleep is more important than hypoxia in the aetiology of daytime sleepiness in heart failure. Overnight oximetry is a useful screening test for Cheyne-Stokes respiration in patients with known heart failure.
- Keywords: Cheyne-Stokes respiration; nocturnal desaturation; heart failure .
- In 1818 Cheyne first described a case of periodic respiration during sleep in a patient with terminal heart failure. ... 2,3 Studies performed in the United States have shown that sleep apnoea is common in moderate to severe heart failure. ...
- The prevalence of occult sleep disordered breathing in heart failure patients in the United Kingdom is unknown. ...
- Our study was performed in patients with stable heart failure in their own homes. ... The purpose of the study was to validate the use of oximetry as a screening tool for Cheyne-Stokes respiration in patients with known heart failure, to assess the prevalence and severity of nocturnal desaturation, and to compare these with the results of Holter monitoring. ...
- One hundred and four patients were recruited from a specialist heart failure clinic. ... All patients had stable cardiac failure with no change in medication for four weeks before study and no evidence of fluid retention at the time of study. ... Digoxin and blockers were not considered to be standard treatment for heart failure. ...
- Heart failure was diagnosed on the basis of a suggestive medical history and examination findings together with visually impaired left ventricular function on cross sectional echocardiography. ...
- Thirteen patients agreed to home oximetry on two successive night to allow the short term reproducibility of this technique to be assessed in heart failure. ...
