Fungal Endocarditis: Causes, Symptoms, And Treatment
Fungal endocarditis is a serious infection affecting the heart valves caused by fungi. This condition can lead to severe complications if left untreated. The fungus enters the bloodstream and infects the heart valves, disrupting their normal function. It is important to seek prompt medical attention if you suspect you may have fungal endocarditis. By understanding the risks and taking appropriate preventive measures, you can reduce your chances of developing this potentially life-threatening condition.
What Are the Symptoms of Fungal Endocarditis?
Fungal endocarditis can cause symptoms like fever, chills, fatigue, weight loss, and night sweats. Patients may also experience shortness of breath, chest pain, and a persistent cough. Other signs include skin rashes, joint pain, and swollen limbs. Prompt medical attention is crucial if you suspect you have fungal endocarditis to prevent serious complications.
- Persistent fever that doesn't go away even with medication may be a sign of fungal endocarditis, a serious heart infection caused by fungi.
- Feeling unusually tired or fatigued, even with enough rest, could be a symptom of fungal endocarditis affecting your heart's ability to function properly.
- Sudden weight loss without trying or changes in appetite may indicate a fungal infection in your heart valves, known as fungal endocarditis.
- Developing shortness of breath or difficulty breathing, especially with minimal exertion, might be a warning sign of fungal endocarditis impacting your heart's function.
- Experiencing chest pain that worsens with deep breathing, coughing, or physical activity could be a sign of fungal endocarditis, as the infection can cause inflammation and damage to the heart valves or surrounding tissues.

People with weakened immune systems, history of intravenous drug use, or previous heart valve issues are at higher risk. Candida and Aspergillus species are common culprits. Treatment involves antifungal medications and may require heart valve surgery in severe cases.
- Candida species, particularly Candida albicans, are a common cause of fungal endocarditis, often affecting individuals with underlying immunocompromised conditions.
- Aspergillus species can also lead to fungal endocarditis in patients with a history of intravenous drug use or those who have undergone cardiac surgery.
- Histoplasma capsulatum, a dimorphic fungus found in soil contaminated with bird or bat droppings, can infect the heart valves and cause endocarditis.
- Cryptococcus neoformans, commonly associated with meningitis in immunocompromised individuals, can also be a rare cause of fungal endocarditis.
- Fusarium species, known for causing opportunistic infections in immunocompromised individuals, can also cause fungal endocarditis, particularly in those with prolonged neutropenia or who have undergone organ transplantation.
Types Of Fungal Endocarditis
Fungal endocarditis can be categorized into different types based on the specific fungus causing the infection. The common types include Candida endocarditis, Aspergillus endocarditis, and Histoplasma endocarditis. These types can vary in terms of symptoms, severity, and treatment approaches. It is essential for healthcare providers to accurately diagnose the type of fungal endocarditis to provide appropriate and effective treatment.
- Candida endocarditis is a rare but serious fungal infection of the inner lining of the heart valves, primarily affecting individuals with compromised immune systems or those who have undergone heart surgery.
- Aspergillus endocarditis is a fungal infection caused by the Aspergillus species, commonly affecting individuals with pre-existing heart conditions or a history of intravenous drug use, presenting with symptoms such as fever, fatigue, and heart murmurs.
- Histoplasma endocarditis is a fungal infection caused by Histoplasma capsulatum, a fungus found in soil contaminated with bird or bat droppings, leading to inflammation of the heart valves and potentially life-threatening complications in immunocompromised patients.
Risk Factors
Risk factors for fungal endocarditis include a compromised immune system, intravenous drug use, prosthetic heart valves, previous heart surgery, and underlying heart conditions. Other predisposing factors include long-term use of broad-spectrum antibiotics, intravascular catheters, and immunosuppressive therapy. Patients with these risk factors are more susceptible to developing fungal endocarditis, a serious infection of the heart valves caused by fungi.
- Individuals with compromised immune systems, such as those with HIV/AIDS or undergoing chemotherapy, are at an increased risk for fungal endocarditis.
- Intravenous drug users who inject drugs using non-sterile equipment are more susceptible to developing fungal endocarditis due to the introduction of fungal organisms into the bloodstream.
- Patients with underlying heart conditions, such as congenital heart defects or prosthetic heart valves, have a higher likelihood of developing fungal endocarditis.
- Those who have previously undergone heart surgeries or procedures, especially if there were postoperative complications, are at a heightened risk for fungal endocarditis.
- People with a history of recurrent or chronic infections, particularly fungal infections elsewhere in the body, are more prone to develop fungal endocarditis.

Diagnosis of Fungal Endocarditis
Doctors will look for signs of infection, such as fever and abnormal heart sounds. They may also perform a biopsy to confirm the presence of fungi in the heart valves. Early diagnosis is crucial for effective treatment and preventing complications.
- Blood cultures: This is a common method to detect fungal endocarditis by analyzing blood samples for the presence of fungal organisms.
- Echocardiography: Both transthoracic and transesophageal echocardiography can help visualize abnormalities in the heart valves, which may indicate fungal endocarditis.
- Serologic tests: Specific antibody tests can be conducted to identify fungal infections that may be causing endocarditis.
- Imaging studies: CT scans, MRI scans, or PET scans can provide detailed images of the heart and surrounding tissues to look for signs of fungal endocarditis.
- Biopsy: A tissue sample taken from the heart valve during surgery can be examined under a microscope to confirm the presence of fungal organisms and to identify the specific type of fungus causing the endocarditis.
Treatment for Fungal Endocarditis
Treatment for fungal endocarditis typically involves a combination of antifungal medications, such as fluconazole or amphotericin B, along with antibiotics to target the specific fungus causing the infection. In severe cases, surgery may be necessary to remove infected heart tissue. It is crucial to follow your healthcare provider's recommendations closely and attend all follow-up appointments to ensure the best outcomes.
- Antifungal Therapy: The mainstay of treatment for fungal endocarditis involves the administration of antifungal medications, such as amphotericin B or echinocandins, to target the fungal infection within the heart valves.
- Surgical Intervention: In severe cases of fungal endocarditis where there is significant damage to the heart valves or persistent infection despite antifungal therapy, surgical intervention may be necessary to repair or replace the affected valves.
- Prolonged Antibiotic Therapy: Fungal endocarditis often requires a prolonged course of antifungal therapy, typically lasting several weeks to months, to ensure complete eradication of the infection and reduce the risk of recurrence.
- Monitoring and Follow-Up: Close monitoring during antifungal treatment is essential to assess the patient's response to therapy and to detect any potential complications such as relapse or side effects from the medications.

How do I recognize the signs of fungal endocarditis?
Look for symptoms like fever, fatigue, weight loss, and heart murmur. Seek immediate medical attention if you suspect fungal endocarditis.
How should I care for myself with fungal endocarditis—what should I do and avoid?
Take prescribed antifungal meds, rest, eat well. Avoid alcohol, smoking, and untreated intravenous drug use to prevent complications and aid recovery.
