How serious is bacterial endocarditis?
When a person has bacterial endocarditis, these valves may not be able to work properly. This can force the heart to work harder to get blood out to the body. Sometimes the heart can’t pump out enough blood. Bacterial endocarditis is a serious condition that can sometimes lead to death.
How can you get bacterial endocarditis?
- Artificial Heart Valve- Through this the person is exposed to exogenous infection, so in few cases infection is initiated in early stages of replacement. ...
- Cardiac implantations
- Hemodialysis is another route through which bacteria gain entry into the bloodstream.

What causes bacterial endocarditis?
Causes. Subacute bacterial endocarditis (SBE) is usually caused by streptococcal species (especially viridans streptococci), and less often by staphylococci. SBE often develops on abnormal valves after asymptomatic bacteremias (bacteria traveling through the bloodstream) from infected gums, or from gastrointestinal, urinary, or pelvic procedures.

Streptococcal infection tends to be more chronic, though the average incubation period is 1 to 2 weeks.
Is endocarditis acute or subacute?
Endocarditis has traditionally been classified as acute or subacute based upon the pathogenic organism and the clinical presentation. This distinction has become less clear, however, and the less specific term "infective endocarditis" is now more commonly used.
Can endocarditis be fatal?
If bacterial endocarditis is not adequately treated, it can be fatal. This is dependent on the infecting organism. Even when treated, further damage to a heart valve may can to heart failure. In addition, blood clots can form and travel throughout the bloodstream to the brain or lungs.
What are the recommendations for antibiotics for endocarditis?
The current American Heart Association recommendations for the use of antibiotics for endocarditis prophylaxis have largely been derived from empiric data and clinical experience. Recommendations are determined by the type of congenital heart disease and the specific procedure.
How many cases of endocarditis have been attributed to acupuncture?
Six cases of subacute bacterial endocarditis have been attributed to acupuncture. In five cases, the patients’ heart valves were already abnormal following surgery or as a result of rheumatic fever. Three cases occurred after using indwelling needles, which are a recognized risk; but three occurred after sessions of normal body acupuncture, which is harder to explain (see above). The full circumstances of the acupuncture are unknown in these cases, as they were reported by staff unconnected with the treatment. No particular precautions are currently advised with regard to sessions of body acupuncture treatment in patients with heart valve abnormalities.
What are the most common skin lesions of endocarditis?
The cutaneous lesions of subacute bacterial endocarditis consist of petechiae, subungual splinter hemorrhages, Osler's nodes, and Janeway lesions.177 Petechiae tend to occur in small crops, particularly in the conjunctivae, on the palate, and on the upper part of the chest and extremities, and they are the most common skin lesions of endocarditis (see Fig. 82-2 ). Rarely, petechiae are extremely numerous, particularly on the lower extremities, and suggest a primary vasculitis. Osler's nodes are split pea–sized, erythematous, tender nodules located principally on the pads of the fingers and toes. They are few in number at any given time and occur in about 15% of patients with subacute bacterial endocarditis. The lesions are usually transient and clear in 1 to 2 days. Similar lesions may also occur in acute endocarditis (e.g., secondary to S. aureus ). Histologic examination of such lesions in several cases of acute endocarditis has suggested septic embolization in their pathogenesis. 178 The genesis of Osler's nodes in subacute bacterial endocarditis may have a different basis, perhaps sterile embolization or an allergic vasculitis. Janeway lesions (see Fig. 82-3) are painless, small, erythematous macules or minimally nodular hemorrhages in the palms or soles that occur in acute or subacute endocarditis—more commonly in the former, particularly if S. aureus is the cause, in which case they occur in 6% of patients. 179 Histologic findings in a case of S. aureus endocarditis have indicated that Janeway lesions are caused by septic microembolization. 178 Gangrenous or hemorrhagic lesions resembling Janeway lesions have been observed in marantic endocarditis 180 and in a patient with end-stage renal failure and dystrophic cardiac valvular calcification. 181
What is SBE in medical terms?

How do you know if you have endocarditis?
Flulike symptoms with low-grade fever, cough, decreased appetite, nausea, weight loss, generalized myalgias, and joint pains may all be present. Physical examination often reveals a fever and a heart murmur. Acute endocarditis develops rapidly over several days to weeks with high fevers, malaise, a toxic appearance, and congestive heart failure. A new or changing murmur is more common with acute endocarditis due to the larger size of vegetations associated with it. However, as few as one quarter of children with endocarditis have a new murmur noted on examination. 23,24 Physical findings of embolic phenomena (arterial clot, stroke) are also more common in acute endocarditis.
What is the diagnosis of streptococcal infection?
Diagnosis is generally made on clinical grounds with typical history, physical examination, and evidence of previous streptococcal infection either by culture done at time of infection or by serology in the setting of an acute nephritis picture.
Can congenital heart disease cause bacteremia?
To prevent this from occurring , patients with congenital heart disease are given oral or intra venous antibiotics prior to undergoing a procedure that may lead to bacteremia. The most common of these procedures in children are dental cleaning and the filling of dental caries.
How to treat endocarditis?
Treatment. Many people with endocarditis are successfully treated with antibiotics. Sometimes, surgery may be needed to fix or replace damaged heart valves and clean up any remaining signs of the infection.
What is the diagnosis of endocarditis?
Diagnosis. Your doctor will consider your medical history, your signs and symptoms, and your test results when making a diagnosis of endocarditis. The diagnosis is usually based on several factors instead of a single positive test result or symptom. Tests used to confirm or rule out endocarditis include:
Why do you need heart valve surgery?
Surgery. Heart valve surgery may be needed to treat persistent endocarditis infections or to replace a damaged valve. Surgery is also sometimes needed to treat endocarditis that's caused by a fungal infection.
How long does it take for endocarditis to clear up?
You'll usually take antibiotics for several weeks to clear up the infection. If endocarditis is caused by a fungal infection, your doctor will prescribe antifungal medication. Some people need lifelong antifungal pills to prevent endocarditis from returning.

What is the purpose of echocardiogram?
Echocardiogram. An echocardiogram uses sound waves to produce images of your heart while it's beating. This test shows how your heart's chambers and valves are pumping blood through your heart. Your doctor may use two different types of echocardiograms to help diagnose endocarditis.
How to tell if you have bacterial endocarditis?
Sometimes doctors insert an ultrasound probe into the esophagus or “food pipe” (transesophageal echo) to obtain a closer more detailed look at the heart.

Infective endocarditis (IE) [also called bacterial endocarditis (BE), or depending on acuity acute or subacute or chronic bacterial endocarditis (SBE) ] occurs when germs (usually bacteria) enter the blood stream and attach to and attack the lining of the heart valves. Infective endocarditis causes growths (vegetations) on the valves, ...
How long does it take for an IV antibiotic to work?
IV antibiotics is usually given for as long as 6 weeks to cure of the infection. Symptoms are monitored throughout therapy and blood cultures are repeated to determine the effectiveness of treatment. If heart valve and heart damage has occurred, surgery may be required to fix the heart valve and improve heart function.
What is the purpose of the American Heart Association review of the scientific literature?
The American Heart Association conducted a review of the scientific literature to determine the value and effectiveness of antibiotic prophylaxis (preventive antibiotics) before such procedures in reducing the risk of bacterial endocarditis.
Can endocarditis be prevented?
Not all endocarditis can be prevented. Call your doctor if you have symptoms of an infection (See signs of infection listed above). Do not wait a few days until you have a major infection to seek treatment. Colds and the flu do not cause endocarditis.
Can you take antibiotics for valve disease?
Dental procedures (particularly tooth extractions) and endoscopic examinations are associated with bacteria in the blood, so prophylactic (preventative) antibiotics are advised for some patients with valve disease and all patients with valve replacements. Intravenous drug abusers are at high risk for developing IE.
Definition
Description
- Endocarditis has traditionally been classified as acute or subacute based upon the pathogenic organism and the clinical presentation. This distinction has become less clear, however, and the less specific term "infective endocarditis" is now more commonly used. Most patients who develop infective endocarditis have underlying cardiac disease, although this is frequently not th…
Causes
- Subacute bacterial endocarditis (SBE) is usually caused by streptococcal species (especially viridans streptococci), and less often by staphylococci. SBE often develops on abnormal valves after asymptomatic bacteremias (bacteria traveling through the bloodstream) from infected gums, or from gastrointestinal, urinary, or pelvic procedures.
Symptoms
- Most patients present with a fever that lasts several days to 2 weeks. Nonspecific symptoms are common. Cough, shortness of breath, joint pain, diarrhea, and abdominal or flank pain may be present. About 90 percent of patients will have heart murmurs, but murmurs may be absent in patients with right-sided heart infections. A changing murmur is common only in acute endocard…
Diagnosis
- Endocarditis is suspected in a patient with a heart murmur and unexplained fever for at least one week, and in an intravenous drug abuser with a fever, even in the absence of hearing a murmur. A definitive clinical diagnosis requires blood cultures that grow bacteria. Echocardiography (ultrasound study of the heart) may visualize vegetations (growths) on heart valves.
Treatment
- Cure of endocarditis requires eradication of all microorganisms from the vegetation(s), usually on the heart valve. Bacterial endocarditis almost always requires hospitalization for antibiotic therapy, generally given intravenously, at least at the outset. Most patients respond rapidly to appropriate antibiotic therapy, with over 70 percent of pati...
Complications
- If bacterial endocarditis is not adequately treated, it can be fatal. This is dependent on the infecting organism. Even when treated, further damage to a heart valve may can to heart failure. In addition, blood clots can form and travel throughout the bloodstream to the brain or lungs. It is important that you tell your dentist or physician about any risk factors you may have for endocar…
