The recognition of infective endocarditis.

|September 1, 1979
Summary
Emergency physicians can suspect infective endocarditis in patients presenting with fever and heart murmurs. Early identification relies on recognizing systemic signs like fever, malaise, arthralgias, anemia, leukocytosis, and hematuria alongside positive blood cultures.
Area of Science:
- Infectious Diseases
- Cardiology
- Emergency Medicine
Background:
- Infective endocarditis (IE) diagnosis is challenging in emergency departments due to insufficient initial clinical data.
- Early suspicion of IE is crucial for timely intervention and improved patient outcomes.
Purpose of the Study:
- To review clinical and laboratory data of patients with IE initially evaluated in an emergency department.
- To identify key findings that aid emergency physicians in suspecting IE upon initial presentation.
Main Methods:
- Retrospective review of medical records for 22 patients diagnosed with bacterial endocarditis.
- Analysis of initial history, physical examination findings, and laboratory results from emergency department visits.
Main Results:
- Fever (50%) was the most common historical feature; heart murmur (82%) was the most common physical finding.
- All patients had positive blood cultures, with Staphylococcus aureus being the most frequent pathogen.
- Systemic signs (fever, malaise, arthralgias), anemia, leukocytosis, and hematuria were key indicators.
Conclusions:
- Emergency physicians can suspect infective endocarditis by recognizing a combination of fever, heart murmurs, and specific laboratory abnormalities.
- Prompt identification of these clinical and laboratory clues is essential for initiating appropriate diagnostic and therapeutic pathways for IE.
