Revision as of 00:07, 19 August 2020
Background
- Infection of endocardium, generally involving the heart valves, either prosthetic or native
Microbiology
- Bacteria
- Fungi
- Culture-negative endocarditis
Risk Factors
- Cardiac
- Prior endocarditis
- Prosthetic heart valve or implanted device
- Congenital heart disease, especially unrepaired cyanotic congenital heart disease
- Valve abnormalities
- Non-cardiac
- Intravenous drug use
- Indwelling intravenous lines
- Immunosuppression
- Recent dental work or surgical procedure associated with bacteremia
Clinical Manifestations
- In general, symptoms are fever, chills, and malaise in a patient at risk for endocarditis
- Tends to progress rapidly
- May have a new murmur, stroke syndrome, pulmonary embolism, arthralgias
- Refer to Modified Duke criteria
- Specific organisms may be associated with specific risk factors
- Injection drug use: Viridans group streptococci and Pseudomonas aeruginosa
- Colon cancer: Streptococcus gallolyticus subspecies gallolyticus and Clostridium septicum
Subacute Bacterial Endocarditis
- Insidious onset with more pronounced constitutional symptoms progressing over weeks to months
Differential Diagnosis
- Non-infectious causes of endocarditis
- Any cause of fever or consitutional symptoms
Management
- Varies by causative organism and prosthetic vs. native valve
- In patients who are in acute heart failure, may need to consider the sodium content of the antibiotics used
