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.
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.
[3] 10–25% of endocarditis patients will have Osler's nodes. [4] Other signs of endocarditis include Roth's spots and Janeway lesions. The latter, which also occur on the palms and soles, can be differentiated from Osler's nodes because they are non-tender. [2] Osler's nodes can also be seen in Systemic lupus erythematosus; Marantic endocarditis
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 ...
The bacteria initially causes a disease called Q fever, but months or sometimes years after the initial Q fever, they can develop endocarditis, but usually this is in high-risk people, like those that are immunocompromised, pregnant women, and those with pre-existing heart valve defect, which makes it tricky to diagnose unless there’s a ...
Other strains of streptococci can cause subacute endocarditis as well. These include streptococcus intermedius, which can cause acute or subacute infection (about 15% of cases pertaining to infective endocarditis). [7] Enterococci from urinary tract infections and coagulase negative staphylococci can also be causative agents. [5]
Inflammation of the heart valves due to any cause is called valvular endocarditis; this is usually due to bacterial infection but may also be due to cancer (marantic endocarditis), certain autoimmune conditions (Libman-Sacks endocarditis, seen in systemic lupus erythematosus) and hypereosinophilic syndrome (Loeffler endocarditis).
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 GERD), and involves inflammation of the esophagus ...
