Summary
This study of bacterial endocarditis (BE) in Hawaii found Streptococci most common. Most patients survived, but congestive heart failure and stroke were leading causes of death.
Area of Science:
- Infectious Diseases
- Cardiology
- Clinical Microbiology
Background:
- Bacterial endocarditis (BE) is a serious infection affecting heart valves.
- Understanding local epidemiology and treatment outcomes is crucial for community hospitals.
Purpose of the Study:
- To describe the clinical features, microbiology, and predisposing factors of bacterial endocarditis.
- To analyze treatment outcomes and survival rates in a community hospital setting.
Main Methods:
- Retrospective review of 56 patients diagnosed with bacterial endocarditis over 12 years.
- Analysis of causative organisms, clinical presentations, surgical interventions, and mortality causes.
Main Results:
- The average patient age was 52.0 years, with a mean symptom duration of 28.8 days.
- Streptococci were the most frequent causative agents (61%), followed by Gram-negative bacilli (11%).
- Twenty-five percent of patients required cardiac surgery, primarily for severe valvular insufficiency, heart failure, or embolism; 82% survived.
Conclusions:
- Bacterial endocarditis presents with varied durations and is frequently caused by Streptococci in this Hawaiian community.
- While survival rates are high, congestive heart failure and cerebrovascular accidents remain significant causes of mortality, highlighting the need for prompt management.
