Infective Endocarditis is an infection of the inner lining of the heart, usually affecting the heart valves. It occurs when bacteria or other germs enter the bloodstream and attach to damaged areas of the heart. This condition can lead to serious complications, including heart failure or stroke, if not treated promptly. Symptoms of Infective Endocarditis may include fever, chills, fatigue, and heart murmurs. Risk factors include having a history of heart valve problems, previous heart surgery, or certain medical conditions. Diagnosis typically involves blood tests and imaging studies, while treatment usually requires antibiotics or, in severe cases, surgery.
