[medical citation needed] In cases of subacute bacterial endocarditis, the causative organism (streptococcus viridans) needs previous heart valve disease to colonize. [9] On the other hand, in cases of acute bacterial endocarditis the organism can colonize on the healthy heart valve, causing the disease. [10]
Infective endocarditis is divided into the three categories of acute, subacute, and chronic based on the duration of symptoms. [11] Acute infective endocarditis refers to the presence of signs and symptoms of infective endocarditis that are present for days up to six weeks. [11]
In the subacute form of infective endocarditis, a vegetation may also include a center of granulomatous tissue, which may fibrose or calcify. [2] There are several ways to classify endocarditis. The simplest classification is based on cause: either infective or non-infective, depending on whether a microorganism is
The nodes are commonly indicative of subacute bacterial endocarditis. [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.

Infective endocarditis used to be classified into groups like acute and subacute based on how quickly the infection developed, but nowadays the key is to identify that microbial cause of infection and to treat it as effectively as possible. Viridans Streptococci is the most common cause.
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 ...
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 ...
If they are introduced into the bloodstream, they have the potential of causing endocarditis, in particular in individuals with damaged heart valves. They are the most common causes of subacute bacterial endocarditis. Viridans streptococci are identified in cases of neonatal infections. [6]
