Valves of the heart do not get dedicated supply of blood and the result of this can be that defensive immune system mechanisms like white blood cells cannot directly reach the valves via bloodstream.

If a bacteria or any other organism is attach to the valve surface and forming vegetation, the host immune response will be dulled. The lack in blood supply can also have insinuations in treatment as it is difficult to reach the medicine to the infective valve. In a normal case,

 

 

the blood flows smoothly through valves and if these valves are damaged because on any cause like rheumatic fever, then risks for the bacterial attach to it are more probable to increase.

Infective endocarditis is subdivided into acute and sub-acute forms. Patients having sub-acute infective endocarditis live longer untreated as compared to acute ones. Sub-acute infective endocarditis is due to streptococci and it has low tendency to hematogenously seed extracted cardiac sites. Sub-acute has mild to moderate illness progressing slowing. While, acute infective endocarditis is fulminant illness, which means occur quickly or suddenly,

 

 

Staphylococcus aureus is mainly the cause for it and it has more disease producing capacity. There are some other classification methods for the infective endocarditis like culture positive and culture negative, prosthetic and native-valve endocarditis as well as right sided and left sided.

Signs and symptoms for infective endocarditis include fever, change in heart murmur, weight loss, coughing, anemia, night sweats and clubbing. In a healthy body, the bacterial infections can go normally to be cleared without any treatment but when the heart valve is damaged the bacteria has place to attach and establish more diseases. Other microorganisms may include fungi and viral to cause this condition. High dose anti biotic medicines are suggested to patients of infective endocarditis.
