Disease Category
Endocarditis is an inflammatory infection that occurs in the endocardium, which covers the inside of the heart, particularly the heart valves; it is also known as infective endocarditis.
Core Mechanism
Most cases occur when bacteria enter the bloodstream and settle in the heart, though rarely fungi can be the cause.
Main Causes · Related Factors
Microorganisms in the bloodstream can adhere to and proliferate on damaged or artificial heart tissue or valve surfaces, and may clump with platelets and blood cells to form infectious masses.
Representative Patterns
Representative manifestations include fever and chills, new or worsening heart murmurs, shortness of breath, chest pain, cough, muscle, joint, or back pain, night sweats, and skin changes.
Individual Differences
Valvular disease, congenital heart disease, artificial valves or cardiac devices, previous endocarditis, immunosuppression, long-term central venous catheters, intravenous drug use, advanced age, and poor oral health can increase the risk.
Diagnosis
Symptoms can appear suddenly or gradually, and may be mild or severe; delayed treatment can lead to valve damage, heart failure, arrhythmia, sepsis, or damage to the brain, lungs, kidneys, or spleen.
Management
Diagnosis is determined by comprehensively evaluating cardiac tests, including blood tests, blood cultures, chest imaging, and echocardiography, based on medical history and physical examination.
Treatment/Research Status
It cannot be ruled out based on a single negative blood culture or non-specific symptoms alone; the use of antibiotics, as well as the cause of infection and valve status, may affect test interpretation.
Read Evidence
Management focuses on rapid identification of the cause, antimicrobial therapy, assessment of valve and cardiac function, and monitoring for complications, with consideration of cardiac surgery if necessary.
Key Precautions
Antibiotics are used for bacterial infections and antifungal agents for fungal infections; treatment may continue for a long period, and surgery may be required for damaged valves or tissue.

At a Glance

Endocarditis is an inflammatory infection that occurs in the endocardium, which covers the inside of the heart, particularly the heart valves; it is also known as infective endocarditis.

Representative manifestations include fever and chills, new or worsening heart murmurs, shortness of breath, chest pain, cough, muscle, joint, or back pain, night sweats, and skin changes.

How the disease works

Most cases occur when bacteria enter the bloodstream and settle in the heart, though rarely fungi can be the cause.

Microorganisms in the bloodstream can adhere to and proliferate on damaged or artificial heart tissue or valve surfaces, and may clump with platelets and blood cells to form infectious masses.

Variations in presentation among individuals

Valvular disease, congenital heart disease, artificial valves or cardiac devices, previous endocarditis, immunosuppression, long-term central venous catheters, intravenous drug use, advanced age, and poor oral health can increase the risk.

The broad framework of diagnosis and management

Symptoms can appear suddenly or gradually, and may be mild or severe; delayed treatment can lead to valve damage, heart failure, arrhythmia, sepsis, or damage to the brain, lungs, kidneys, or spleen.

Diagnosis is determined by comprehensively evaluating cardiac tests, including blood tests, blood cultures, chest imaging, and echocardiography, based on medical history and physical examination.

Current status of treatment

It cannot be ruled out based on a single negative blood culture or non-specific symptoms alone; the use of antibiotics, as well as the cause of infection and valve status, may affect test interpretation.

Management focuses on rapid identification of the cause, antimicrobial therapy, assessment of valve and cardiac function, and monitoring for complications, with consideration of cardiac surgery if necessary.

Antibiotics are used for bacterial infections and antifungal agents for fungal infections; treatment may continue for a long period, and surgery may be required for damaged valves or tissue.

How to read clinical trials

During treatment, infectious responses and cardiac complications must be repeatedly evaluated; clinical trial registration or completion should not be interpreted as implying treatment efficacy, approval, or standard of care.

Points to verify during clinical consultations

In clinical practice, recent fever/chills, procedures, dental treatments, medication use, heart disease/devices/prosthetic valves, history of endocarditis, and current antimicrobials must be confirmed with medical staff.
