Treatment of Endocarditis
The treatment of endocarditis aims to eliminate the infection, repair any heart damage, and prevent serious complications. Because endocarditis is potentially life-threatening, patients are typically admitted to hospital for immediate care and monitoring.
Antibiotic Therapy
The primary treatment is high-dose intravenous (IV) antibiotics, given over several weeks. The choice of antibiotic depends on the organism found in blood cultures. Common regimens include:
Penicillin or ceftriaxone, often combined with gentamicin for synergy
Vancomycin for MRSA or penicillin-resistant organisms
Ampicillin, linezolid, or antifungals in special cases
Treatment duration usually ranges from 4 to 6 weeks, depending on the type of organism, the patient’s condition, and whether heart valves are native or artificial.
Patients start IV antibiotics in hospital but may continue treatment at home through outpatient IV therapy (if stable and resources allow). In many South African settings, prolonged hospital stays are more common due to resource constraints and monitoring needs.
Surgery
Surgery is sometimes required when:
There is severe valve damage causing heart failure
Large vegetations are present and at risk of embolism
Abscesses or persistent infection occur despite antibiotics
The infection involves a prosthetic valve
Surgical options include valve repair or replacement. In some cases, especially with fungal endocarditis or drug-resistant bacteria, surgery is urgent.
Supportive Care
Patients may need:
Oxygen for shortness of breath
Diuretics to relieve fluid overload in heart failure
Pain relief and rest
Nutritional support during recovery | Treatment of Endocarditis
Monitoring for complications such as stroke, kidney problems, or embolic events is essential throughout treatment.
In South Africa, public hospitals may face challenges in accessing specialist cardiac surgeons or long-term IV therapy infrastructure. Efforts are underway to decentralise care and improve follow-up in rural areas.
The treatment of endocarditis is intensive but often successful if started early. Completing the full course of antibiotics and following up with cardiac care are key to long-term health.
