Congestive heart failure is a pathophysiological condition in which the heart's output is insufficient to meet the needs of the body and lungs. [10] The term "congestive heart failure" is often used because one of the most common symptoms is congestion or fluid accumulation in the tissues and veins of the lungs or other parts of a person's body ...
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing (dyspnea), leg or feet swelling, and fatigue. [ 1 ] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs ...
Cardiac asthma is the medical condition of intermittent wheezing, coughing, and shortness of breath that is associated with underlying congestive heart failure (CHF). [ 1 ] Symptoms of cardiac asthma are related to the heart's inability to effectively and efficiently pump blood in a CHF patient. [ 2 ] This can lead to accumulation of fluid in ...
High-output heart failure is a heart condition that occurs when the cardiac output is higher than normal because of increased peripheral demand. There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle. These individuals usually have a normal systolic function but ...
The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying the extent of heart failure.It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
Cardiomyopathy is a group of primary diseases of the heart muscle. [ 1 ] Early on there may be few or no symptoms. [ 1 ] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [ 1 ] An irregular heart beat and fainting may occur. [ 1 ]
