Serous pericarditis is usually caused by noninfectious inflammation such as occurs in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Fibrous adhesions rarely occur. Fibrous and serofibrinous pericarditis represent the same basic process and are the most frequent type of pericarditis.

Recurrent pericarditis, like chronic myocarditis, is often considered to be an autoimmune consequence of a prior viral infection.Why does rheumatic fever affect mitral valve?
How does rheumatic fever damage the heart? This infection causes swelling and muscle damage to the heart. It can also damage the heart valves in a way that keeps the blood from moving through the heart normally. The infection can cause heart valve leaflets to stick together, which narrows the valve opening.
What is the most common complication of rheumatic fever?Rheumatic fever can cause long-term complications in certain situations. One of the most prevalent complications is rheumatic heart disease. Other heart conditions include: Aortic valve stenosis.
Article first time published onDoes rheumatic fever always cause heart damage?
Rheumatic fever can cause permanent damage to the heart, including damaged heart valves and heart failure. Treatments can reduce damage from inflammation, lessen pain and other symptoms, and prevent the recurrence of rheumatic fever.
Does rheumatic fever weaken the heart?
Serious Complications Include Long-term Heart Damage If rheumatic fever is not treated promptly, long-term heart damage (called rheumatic heart disease) may occur. Rheumatic heart disease weakens the valves between the chambers of the heart. Severe rheumatic heart disease can require heart surgery and result in death.
Which valve is most commonly affected by rheumatic heart disease?
Rheumatic heart disease most commonly affects the mitral valve (which has only two leaflets; Figure 2) or the aortic valve, but any valve can be affected, and more than one can be involved.
What happens if rheumatic heart disease is left untreated?
If left untreated, rheumatic heart disease can lead to heart valve damage, stroke, heart failure, and death.
How does rheumatic fever cause mitral stenosis?
Causes of Mitral Valve Stenosis Rheumatic fever: Rheumatic fever, a complication of strep throat or scarlet fever, is the most common cause of mitral valve stenosis. As a result of rheumatic fever, the mitral valve can thicken, reducing blood flow through the heart.
How do you confirm pericarditis?
Blood tests are usually done to check for signs of a heart attack, inflammation and infection. Other tests used to diagnose pericarditis include: Electrocardiogram (ECG). An electrocardiogram is a quick and painless test that records the electrical signals in your heart.
What can mimic pericarditis?
In addition to these conditions, chest pain that can mimic pericarditis is seen in a wide range of conditions including gastric inflammation (gastritis) or ulcers, esophageal inflammation (esophagitis) and gastroesophageal reflux disease (GERD), clots in the arteries of the lung (pulmonary embolism), inflammation of …

Does rheumatic fever only affect the mitral valve?
Although rheumatic fever can affect any heart valve, it most commonly affects the mitral valve which lies between the two chambers of the left side of the heart. The damage can cause valve stenosis, valve regurgitation and/or damage to the heart muscle.
Can rheumatic fever cause mitral valve prolapse?
However, more recent surgical pathologic data also have demonstrated a high incidence of mitral valve prolapse in cases of rheumatic heart disease, which suggests that rheumatic fever may be a cause of mitral valve prolapse.
Can rheumatic fever cause cardiomegaly?
If the valves are damaged by conditions such as rheumatic fever, a heart defect, infections (infectious endocarditis), an irregular heartbeat (atrial fibrillation) connective tissue disorders, certain medications or radiation treatments for cancer, your heart may enlarge.
Will my pericarditis ever go away?
Pericarditis is often mild and goes away on its own. Some cases, if not treated, can lead to chronic pericarditis and serious problems that affect your heart. It can take weeks or months to recover from pericarditis.
Does pericarditis always show on ECG?
Laboratory tests – markers of inflammation [14] Interestingly, pericarditis patients with elevated biomarkers of myocardial injury almost always exhibit ECG changes characteristic of ST-segment elevation.
What does pericarditis pain feel like?

Is the carditis in acute rheumatic fever the same as rheumatic heart disease?
The most common presenting features of ARF are fever (>90% of patients) and arthritis (75% of patients). The most serious manifestation is carditis (>50% of patients) because it can lead to chronic rheumatic heart disease—while all other clinical features fully resolve, often within weeks.
