Infective endocarditis pathophysiology
infective endocarditis is an infection in the heart valves or endocardium. The endocardium is the lining of the interior surfaces of the chambers of the heart. This condition is usually caused by bacteria entering the bloodstream and infecting the heart.
Approximately 80% of infective endocarditis cases are caused by the bacteria streptococci and staphylococci. The third most common bacteria causing this disease is enterococci, and, like staphylococci, is commonly associated with healthcare-associated infective endocarditis.
Endocarditis is caused by bacteria in the bloodstream multiplying and spreading across the inner lining of your heart (endocardium). The endocardium becomes inflamed, causing damage to your heart valves. Your heart is usually well protected against infection so bacteria can pass harmlessly by.
