Congestive heart failure (CHF) is a chronic condition that affects the pumping power of your heart muscles.
Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.
Those stages were updated and revised in 2005. Understanding these stages can help you recognize that congestive heart failure is a progressive disease that can worsen over time. Here is a description of the 4 Stages of Congestive Heart Failure: Stage A. At this stage, you do not have congestive heart failure, nor do you show any signs or symptoms.
Congestive heart failure is a serious medical condition in which the heart cannot pump enough blood to meet the body’s needs. As blood flow out of the heart slows, blood returning to the heart through the veins backs up, causing congestion in the body’s tissues.
End-of-Life Signs: Congestive Heart Failure. Nearly 6 million Americans suffer from Congestive Heart Failure. Congestive Heart Failure (CHF) occurs when the heart is unable to pump blood fast enough, resulting in swelling, shortness of breath, and other issues.
Congestive hepatopathy, also known as nutmeg liver and chronic passive congestion of the liver, is liver dysfunction due to venous congestion, usually due to congestive heart failure. The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins. The paler areas are unaffected surrounding liver tissue. When severe and longstanding, hepatic congestion can lead to fibrosis; if congestion is due to right heart failure, it is called cardiac cirrhosis.
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 amyloidosis (in which misfolded proteins are deposited in the heart muscle, causing it to stiffen). Over time these increases in workload will produce changes to the heart itself: The heart of a person with heart failure may have a reduced force of contraction due to overloading of the ventricle. In a healthy heart, increased filling of the ventricle results in increased contraction force (by the Frank–Starling law of the heart) and thus a rise in cardiac output. In heart failure, this mechanism fails, as the ventricle is loaded with blood to the point where heart muscle contraction becomes less efficient. This is due to reduced ability to cross-link actin and myosin filaments in over-stretched heart muscle. A reduced stroke volume may occur as a result of a failure of systole, diastole or both.
Heart failure (HF), also known as chronic heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs. Signs and symptoms of heart failure commonly include shortness of breath, excessive tiredness, and leg swelling. The shortness of breath is usually worse with exercise, while lying down, and may wake the person at night. A limited ability to exercise is also a common feature. Chest pain, including angina, does not typically occur due to heart failure. Common causes of heart failure include coronary artery disease including a previous myocardial infarction (heart attack), high blood pressure, atrial fibrillation, valvular heart disease, excess alcohol use, infection, and cardiomyopathy of an unknown cause. These cause heart failure by changing either the structure or the functioning of the heart. The two types of heart failure - heart failure with reduced ejection fraction (HFrEF), and heart failure with preserved ejection fraction (HFpEF) - are based on whether the ability of the left ventricle to contract is affected, or the heart's ability to relax.
