Overivew
In endocarditis, the white blood cell count and erythrocyte sedimentation rate are elevated. The rheumatoid factor is elevated in half of patients. The BUN and Cr may be elevated in the presence of glomerulonephritis. The EKG can show conduction abnormalities in the presence of a myocardial abscess. The EKG can show ST elevation in the presence of embolization of a vegetation or clot down the coronary artery.
Laboratory Findings
Leukocytosis
A marked leukocytosis is present.
Erythrocyte Sedimentation Rate
An elevated erythrocyte sedimentation rate is present.
Rheumatoid Factor
A positive serum rheumatoid factor may be present and is present in approximately 50% of patients with subacute disease. It becomes negative after successful treatment.
Renal Function
The serum BUN and Cr may be elevated if glomerulonephritis is present.
Urinalysis
Glomerulonephritis may be present.
2008 and Incorporated 2006 ACC/AHA Guidelines for the Management of Patients with Valvular Heart Disease (DO NOT EDIT) [1]
Evaluation (DO NOT EDIT) [1]
| Class I |
| "1. Patients at risk for infective endocarditis who have unexplained fever for more than 48 h should have at least 2 sets of blood cultures obtained from different sites. (Level of Evidence: B)" |
| Class III |
| "1. Patients with known valve disease or a valve prosthesis should not receive antibiotics before blood cultures are obtained for unexplained fever. (Level of Evidence: B)" |
