Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart. [8] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [1] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [1]
An ECG showing pericarditis. Note the ST elevation in multiple leads with slight reciprocal ST depression in aVR. Acute pericarditis is a type of pericarditis (inflammation of the sac surrounding the heart, the pericardium) usually lasting less than 4 to 6 weeks. [1] It is the most common condition affecting the pericardium.
The "swinging" heart. A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space ...
Dressler syndrome is a secondary form of pericarditis that occurs in the setting of injury to the heart or the pericardium (the outer lining of the heart). It consists of fever, pleuritic pain, pericarditis and/or pericardial effusion. Dressler syndrome is also known as postmyocardial infarction syndrome[1] and the term is sometimes used to ...
The appearance of myopericarditis is associated with infections such as acute tonsillitis, pneumonia, and gastroenteritis. [2] Smallpox vaccination has been a known risk factor for myocarditis and pericarditis since the 1950s. [3] In 1983, an incidence of myocarditis of 1 per 10 000 was reported among Finnish military personnel. [4]
If the pain is pleuritic in nature, it may suggest acute pericarditis caused by bleeding into the sac surrounding the heart. This is a particularly dangerous eventuality, suggesting that acute pericardial tamponade may be imminent. Pericardial tamponade is the most common cause of death from AD. [8]
Pericarditis can be acute, meaning it happens suddenly or chronic — it can develop over time and may take longer to treat. Both types can disrupt the heart’s normal function, said the American ...
hibernating myocardium, silent ischemia, myocardial infarction, acute pericarditis, myocarditis, pulmonary embolism. Myocardial stunning or transient post-ischemic myocardial dysfunction is a state of mechanical cardiac dysfunction that can occur in a portion of myocardium without necrosis after a brief interruption in perfusion, despite the ...
