What is the pathophysiology of congestive heart failure?
Congestive heart failure is a syndrome that can be caused by a variety of abnormalities, including pressure and volume overload, loss of muscle, primary muscle disease or excessive peripheral demands such as high output failure. In the usual form of heart failure, the heart muscle has reduced contractility.
What causes decompensation?
The condition is caused by severe congestion of multiple organs by fluid that is inadequately circulated by the failing heart. An attack of decompensation can be caused by underlying medical illness, such as myocardial infarction, an abnormal heart rhythm, infection, or thyroid disease.
What is the first stage of congestive heart failure?
Congestive heart failure stages
| Stage | Main symptoms |
|---|---|
| Class 1 | You don’t experience any symptoms during typical physical activity. |
| Class 2 | You’re likely comfortable at rest, but normal physical activity may cause fatigue, palpitations, and shortness of breath. |
What are the beginning stages of congestive heart failure?
Symptoms
- Shortness of breath with activity or when lying down.
- Fatigue and weakness.
- Swelling in the legs, ankles and feet.
- Rapid or irregular heartbeat.
- Reduced ability to exercise.
- Persistent cough or wheezing with white or pink blood-tinged mucus.
- Swelling of the belly area (abdomen)
What is the pathophysiology of decreased cardiac output?
A decrease in RV output leads to a decrease in LV filling, which results in decreased cardiac output. Because the right coronary artery originates from the aorta, decreased LV output causes decreased right coronary blood flow and ischemia to the RV wall.
What is the life expectancy of a patient with congestive heart failure?
It is possible to live with congestive heart failure for years after it develops. According to Merck.com, fewer than than 30 percent of patients live longer than 10 years with the condition, and 50 percent of people with the most serious cases live for two years or longer. Treatment can improve life expectancy, but heart failure isn’t curable.
What tests determine congestive heart failure?
EKG Test: This measures how fast your heart is beating and looks for an irregular heart rhythm.
What are the end signs of congestive heart failure?
The affected person can begin feeling anxious,restless,unable to sleep,and loses her appetite.
What are symptoms of congestive cardiac failure?
The course of congestive heart failure in any given patient is extremely variable. An early symptom of congestive heart failure is fatigue. While fatigue is a sensitive indicator of possible underlying congestive heart failure, it is obviously a nonspecific symptom that may be caused by many other conditions.
