Congestive heart failure is the syndrome in which the heart has a reduced ability to fill or pump blood. This leads to a state where the heart is not pumping enough blood to get tissues adequate oxygen.
Which is the best definition of congestive heart failure?
: heart failure in which the heart is unable to maintain an adequate circulation of blood in the bodily tissues or to pump out the venous blood returned to it by the veins.
What defines congestive heart failure?
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.
What is the major cause of congestive heart failure quizlet?
The most common cause of Left-Sided Failure is hypertension and aortic or mitral valve disease. -For Right-Sided Failure common causes include pulmonary valve stenosis, emphysema and pulmonary hypertension secondary to pulmonary emboli.
Why is it called congestive heart failure?
The extra fluid in the circulation builds up in the lungs, the liver, around the eyes, and sometimes in the legs. This is called fluid “congestion” and for this reason doctors call this “congestive heart failure”.
Is congestive heart failure the same as a heart attack?
Heart attacks and heart failure are both types of heart disease, but are different conditions. Heart attacks are when there is a loss of blood supply to the heart, while heart failure is when the heart is unable to pump blood around the body efficiently.
What is the difference between congestive heart failure and heart failure?
Congestive heart failure (CHF) is a type of heart failure which requires seeking timely medical attention, although sometimes the two terms are used interchangeably. 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.
How do they remove fluid from congestive heart failure?
The current in-hospital treatment for CHF involves removal of excess fluid with diuretic medication and/or ultrafiltration in which a machine bypasses the kidneys and filters water and salt from the body. However, these treatments can have unwanted side effects such as low blood pressure and worsening kidney function.
How do congestive heart failure patients die?
Approximately 90% of heart failure patients die from cardiovascular causes. Fifty per cent die from progressive heart failure, and the remainder die suddenly from arrhythmias and ischaemic events.
What are the signs of end stage congestive heart failure?
The symptoms of end-stage congestive heart failure include dyspnea, chronic cough or wheezing, edema, nausea or lack of appetite, a high heart rate, and confusion or impaired thinking. Learn about the hospice eligibility requirements for end-stage heart failure.
What are the signs and symptoms of CHF quizlet?
Terms in this set (3)
- Signs 1-5. Cold, pale, possibly cyanotic extremities, Weight gain, Peripheral edema, Hepatomegaly, Jugular venous distention.
- Signs 6-10. Crackles (rales), Tubular breath sounds and consolidation S3 heart sound, Sinus tachycardia, Decreases exercise tolerance and physical work capacity.
- Symptoms 1/6.
What is the main physiological problem in most types of heart failure?
The problem in heart failure is that the heart isn’t pumping out enough blood each time it beats (low stroke volume). To maintain your cardiac output, your heart can try to: Beat faster (increase your heart rate). Pump more blood with each beat (increase your stroke volume).
Is pulmonary edema caused by right heart failure?
Heart-related (cardiogenic) pulmonary edema. Cardiogenic pulmonary edema is caused by increased pressures in the heart. It’s usually a result of heart failure. When a diseased or overworked left ventricle can’t pump out enough of the blood it gets from your lungs, pressures in the heart go up.
What is the life expectancy for an elderly person with congestive heart failure?
Although there have been recent improvements in congestive heart failure treatment, researchers say the prognosis for people with the disease is still bleak, with about 50% having an average life expectancy of less than five years. For those with advanced forms of heart failure, nearly 90% die within one year.
Can you recover from congestive heart failure?
Dr. Werden says full recovery depends on a variety of things, such as how well a patient responds to medication. A minority of people with congestive heart failure require surgery, and some will never enjoy the high quality of life they did before their hearts failed.
What is a sign of worsening heart failure in older adults?
Early signs of heart failure in the elderly are similar to those found in other age groups, which include worsening or shortness of breath, fatigue, bloating, lack of appetite, persistent cough, lack of appetite and nausea. Other symptoms may include a mental decline or depression.
