What is the main cause of congestive heart failure?
The most common cause of congestive heart failure is coronary artery disease. Risk factors for coronary artery disease include: high levels of cholesterol and/or triglyceride in the blood. high blood pressure.
What is the pathology of heart disease?
Coronary heart disease, also called coronary artery disease or ischemic heart disease, disease characterized by an inadequate supply of oxygen-rich blood to the heart muscle (myocardium) because of narrowing or blocking of a coronary artery by fatty plaques (see atherosclerosis).
What is the pathophysiology of heart failure that results in impaired cardiac output?
Cardiac and Vascular Changes Overall, the changes in cardiac function associated with heart failure result in a decrease in cardiac output. This results from a decline in stroke volume that is due to systolic dysfunction, diastolic dysfunction, or a combination of the two.
What is pathophysiology of left sided heart failure?
Left-sided heart failure occurs when the left ventricle, the heart’s main pumping power source, is gradually weakened. When this occurs, the heart is unable to pump oxygen-rich blood from the lungs to the heart’s left atrium, into the left ventricle and on through the body and the heart has to work harder.
What kind of cough is associated with heart failure?
Warning Signs of Heart Failure
| Sign or Symptom | People with Heart Failure May Experience… | Why It Happens |
|---|---|---|
| Persistent coughing or wheezing | …coughing that produces white or pink blood-tinged mucus. | Fluid builds up in the lungs (see above). |
Can ECG detect heart failure?
Electrocardiogram (ECG or EKG) to assess the heart rate and rhythm. This test can often detect heart disease, heart attack, an enlarged heart, or abnormal heart rhythms that may cause heart failure. Chest X-ray to see if the heart is enlarged and if the lungs are congested with fluid.
Does heart failure show up in blood tests?
Tests you may have to diagnose heart failure include: blood tests – to check whether there’s anything in your blood that might indicate heart failure or another illness. an electrocardiogram (ECG) – this records the electrical activity of your heart to check for problems.
How do you check for heart failure?
Diagnostic tests for congestive heart failure may include:
- Resting or exercise electrocardiogram (also known as EKG, ECG, or stress test)
- Echocardiogram.
- Computed tomography (CT) scan.
- Magnetic resonance imaging (MRI) scan.
- Positron Emission Tomography (PET) scan.
- Biopsy or catheterization of the heart and arteries.
