Explain how IE can cause both heart failure and neurologic injury.
Answer
Vegetations involving the aortic or mitral valve can impair valve function and cause heart failure. Vegetations can also embolize to the systemic circulation, producing cerebral infarction or abscess; staphylococcal disease is associated in the lecture with neurologic complications.
Explanation
IE can damage cardiac structures locally and cause distant injury through embolization. Myocardial abscess and toxic myocarditis are additional mechanisms contributing to heart failure. **Key takeaway:** Local cardiac damage and embolic spread explain distinct major complication pathways. **Glossary:** Embolization: movement of material through blood vessels to another site.
