Microscopically, Aschoff bodies are areas of inflammation of the connective tissue of the heart, or focal interstitial inflammation.Fully developed Aschoff bodies are granulomatous structures consisting of fibrinoid change, lymphocytic infiltration, occasional plasma cells, and characteristically abnormal macrophages surrounding necrotic centres.
Myocarditis is the inflammation of the heart muscle; Endocarditis is the inflammation of the endocardium; Pancarditis, also called perimyoendocarditis, is the inflammation of the entire heart: the pericardium, the myocardium and the endocardium; Reflux carditis refers to a possible outcome of esophageal reflux [citation needed] (also known as ...
As defined, acute inflammation is an immunovascular response to inflammatory stimuli, which can include infection or trauma. [25] [26] This means acute inflammation can be broadly divided into a vascular phase that occurs first, followed by a cellular phase involving immune cells (more specifically myeloid granulocytes in the acute setting). [25]
Eosinophilic myocarditis is often viewed as a disorder that has three progressive stages. The first stage of eosinophilic myocarditis involves acute inflammation and cardiac cell necrosis (i.e. areas of dead cells); it is dominated by symptoms characterized as the acute coronary syndrome such as angina, heart attack and/or congestive heart failure.
The elevation of these substances may occur when inflammation of the heart's muscular layer in addition to acute pericarditis. [2] Also, ST elevation on EKG (see below) is more common in those patients with a cTnI > 1.5 μg/L. [7] Coronary angiography in those patients should indicate normal vascular perfusion. Troponin levels increase in 35-50 ...
Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves. Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
Experts say it could ‘revolutionise the way we diagnose myocarditis’, allowing early treatment and support.
Depending on the time of presentation and duration, pericarditis is divided into "acute" and "chronic" forms. Acute pericarditis is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or even as a result of a heart attack (myocardial infarction), as Dressler's syndrome.
