What is the difference between endocarditis and myocarditis?
The main difference between pericarditis, myocarditis, and endocarditis is the layer affected. Pericarditis is inflammation in the pericardium, myocarditis inflames the myocardium, and endocarditis means inflammation in the endocardium.
What is sarcoid myocarditis?
Cardiac sarcoidosis is a rare inflammatory condition where groups of immune cells form granulomas in different areas of the heart which can cause issues from arrhythmia to heart failure.
What are the symptoms of endocarditis and myocarditis?
Symptoms
- Aching joints and muscles.
- Chest pain when you breathe.
- Fatigue.
- Flu-like symptoms, such as fever and chills.
- Night sweats.
- Shortness of breath.
- Swelling in your feet, legs or abdomen.
- A new or changed heart murmur, which is the heart sound made by blood rushing through your heart.
What is the most common cause of myocarditis?
Myocarditis Causes Myocarditis is rare, but when it occurs, it is most commonly caused by an infection in the body. Infections from viruses (most common, including those that cause the common cold, influenza or COVID-19), bacteria, fungus or parasites can lead to myocardial inflammation.
How is myocarditis diagnosed?
Tests to diagnose myocarditis include:
- Blood tests. Blood tests are usually done to check for signs of a heart attack, inflammation and infection.
- Electrocardiogram (ECG or EKG).
- Chest X-ray.
- Heart MRI (Cardiac MRI).
- Echocardiogram.
- Cardiac catheterization and heart muscle biopsy.
What are signs of cardiac sarcoidosis?
Signs and symptoms related to cardiac sarcoidosis may include:
- Chest pain.
- Shortness of breath (dyspnea)
- Fainting (syncope)
- Fatigue.
- Irregular heartbeats (arrhythmias)
- Rapid or fluttering heart beat (palpitations)
- Swelling caused by excess fluid (edema)
What causes cardiac sarcoidosis?
The causes of cardiac sarcoidosis are not currently known. The disease may be triggered by an over-reaction of the immune system after exposure to an infectious agent (such as bacteria or viruses), chemical, or allergen. It is thought that this causes excessive inflammation and the clustering of white blood cells.
What is the test for myocarditis?
There are no specific blood tests to confirm the diagnosis of myocarditis; however, an otherwise unexplained elevation in troponin (a blood test that indicates heart muscle damage) and/or electrocardiographic features of cardiac injury are supportive.
How is myocarditis detected?
To diagnose myocarditis, a health care provider will typically examine you and listen to your heart with a stethoscope. Blood and imaging tests may be done to check your heart health. Imaging tests can help confirm myocarditis and determine its severity.
What is the gold standard for diagnosing myocarditis?
Several non-invasive diagnostic modalities, including cardiac magnetic resonance imaging (CMR), can be helpful in the diagnosis of myocarditis; however we emphasise that EMB remains the gold standard for the diagnosis of definite myocarditis.
What is the difference between myocarditis and endocarditis?
Myocarditis vs Endocarditis – Differences. Endocarditis is an infection of the endocardium – the inner lining of the heart valves and heart chambers. It usually occurs when fungi, bacteria, or other germs invade the bloodstream and attach to abnormal areas of the heart. Individuals who have congenital abnormalities of the heart valves…
What is myocarditis and what causes it?
Myocarditis is an inflammation of the heart muscle. It occurs mostly as a result of viral infections, but also following exposure to drugs or other toxic substances (e.g. certain chemotherapeutic agents) or due to autoimmune diseases.
How does endocarditis affect the heart?
Endocarditis most often affects the heart valves, but can also occur at shunts or other abnormal communications between cardiac cavities. This pathology can alter the structure and function of the valves, which can lead to a haemodynamic overload of the heart cavities.
What is the function of myocardium and endocardium?
By expanding and contracting, the myocardium enables the heart to pump blood (systole) and relax and fill the heart (diastole). Endocardium: The innermost layer of the heart is the endocardium. It is a layer of connective tissues and organ lining that coats the inner surfaces of the heart chambers, including several valves.
