Purulent pericarditis refers to localized inflammation in the setting of infection of the pericardial sac surrounding the heart. [1] In contrast to other causes of pericarditis which may have a viral etiology, purulent pericarditis refers specifically to bacterial or fungal infection of the pericardial sac. [2]
The cause of pericarditis often remains unknown but is believed to be most often due to a viral infection. [ 4 ] [ 8 ] Other causes include bacterial infections such as tuberculosis , uremic pericarditis , heart attack , cancer , autoimmune disorders , and chest trauma .
This causes a type of shock, called obstructive shock, which can lead to organ damage. [6] Non-cardiac symptoms may also present due to the enlarging pericardial effusion compressing nearby structures. Some examples are nausea and abdominal fullness, dysphagia and hiccups, due to compression of stomach, esophagus, and phrenic nerve respectively ...
One of the most common settings for cardiac tamponade is in the first 7 days after heart surgery. [16] After heart surgery, chest tubes are placed to drain blood. These chest tubes, however, are prone to clot formation. When a chest tube becomes occluded or clogged, the blood that should be drained can accumulate around the heart, leading to ...
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Infective endocarditis is an infection of the inner surface of the heart (endocardium), usually the valves. [1] Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count.
The most common cause of myocardial rupture is a recent myocardial infarction, with the rupture typically occurring three to five days after infarction. [3] Other causes of rupture include cardiac trauma, endocarditis (infection of the heart), [4] [5] cardiac tumors, infiltrative diseases of the heart, [4] and aortic dissection. [citation needed]
The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus , Aggregatibacter (previously Actinobacillus ...
