Endocarditis is an inflammatory disease affecting the inner lining of the heart, called the endocardium. The main forms of endocarditis are acute and chronic endocarditis, which can be caused by infectious agents such as bacteria and fungi, or develop against the background of non-infectious causes, including the presence of artificial heart valves. The main risk with endocarditis is the possibility of developing serious complications such as heart failure, thrombosis, and infections in other organs. The clinical and laboratory manifestations of this disease are very diverse and require a comprehensive approach to diagnosis and treatment to prevent deterioration of the patient's condition.
History of the disease and interesting historical facts
Endocarditis has been known in medical literature since ancient times. The first descriptions of the disease were given by Hippocrates, who mentioned the symptoms of heart inflammation. However, it was only in the 19th century that the concept of endocarditis began to form as an independent disease. An important step in understanding the disease was the discovery of Louis Pasteur, who demonstrated the connection between infections and inflammatory processes at the end of the 19th century. The advent of antibiotics in the mid-20th century opened up new horizons in the treatment of this disease, but despite significant advances in medicine, endocarditis continues to cause significant difficulties in diagnosis and prevention, especially among risk groups.
Epidemiology
According to statistics, endocarditis affects 3 to 10 people per 100,000 population per year, but in some countries this figure may be significantly higher. Different forms of the disease vary significantly in frequency of occurrence: infective endocarditis is more common in people with a predisposition associated with the presence of heart defects or artificial valves. The peak incidence is observed in people of retirement age, among whom the disease may develop against the background of concomitant pathology. According to global studies, up to 30% cases of infective endocarditis end in death, which emphasizes the importance of early diagnosis and treatment.
Genetic predisposition to this disease
Although endocarditis is primarily considered an infectious disease, research suggests that genetic predisposition plays a role in its development. Research has linked certain genes to susceptibility to infections, which may contribute to the development of endocarditis. In particular, mutations in genes involved in the immune response, such as IL6 and TNF, may increase the risk of inflammatory processes in the cardiovascular system. However, genetic factors cannot fully explain the occurrence of endocarditis, making it a multifaceted disease that requires a comprehensive approach to risk assessment.
Risk factors for the development of this disease
Risk factors for endocarditis are divided into two main categories: predisposing conditions and habits that affect cardiovascular health. The main risk factors include:
- The presence of heart defects, including congenital and acquired;
- Use of artificial heart valves;
- Infectious diseases preceding the development of endocarditis;
- Injection of drugs;
- Chronic diseases such as diabetes and HIV;
Additionally, lifestyle factors such as smoking and alcohol abuse can increase the risks.
Diagnosis of this disease
Diagnosis of endocarditis begins with a thorough history and physical examination of the patient, as clinical manifestations can vary. The main symptoms include fever, chills, sweating, fatigue, and chest pain. Laboratory tests help identify signs of inflammation, such as elevated C-reactive protein and erythrocyte sedimentation rate. Radiological tests, such as echocardiography, are key in visualizing changes in the heart valves.
In addition, it is necessary to conduct a differential diagnosis with other diseases, such as microbial infection, especially pneumonia and sepsis, as well as systemic dystrophies and tumor processes.
Treatment
Treatment of endocarditis involves a comprehensive approach, including both conservative and surgical methods. The main focus is on drug therapy: antibiotics are prescribed taking into account the pathogen and its sensitivity. In some cases, surgery is required to replace the affected valve or cleanse the heart cavities. In addition, additional treatment methods may include antipyretics and anti-inflammatory drugs. It is also important to consider the underlying condition of each patient when choosing a treatment regimen.
List of medications used to treat this disease
The list of the most commonly used drugs includes:
- Penicillin;
- Cephalosporins;
- Vancomycin;
- Rifampicin;
- Gentamicin;
Each medication has its own indications and requires an individual approach depending on the sensitivity of microorganisms.
Disease monitoring
Monitoring of patients with endocarditis includes regular follow-up examinations and evaluation of treatment effectiveness. The prognosis of the disease depends on the timeliness of diagnosis and therapy; in the case of acute infective endocarditis, the probability of complications is statistically high. Possible complications include pulmonary embolism and the development of heart failure, which requires constant attention from medical specialists.
Age-related features of the disease
Endocarditis has different manifestations depending on the age group of patients. In children, the disease can develop against the background of congenital heart defects and often requires surgical intervention. At the same time, in older people, endocarditis is often accompanied by concomitant diseases, which can complicate patient care and require a more careful approach to drug therapy.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov, a cardiologist with many years of experience, recommends paying attention to the following aspects when preventing and treating endocarditis:
— Regular medical examinations and timely diagnosis of heart disease are key factors in preventing endocarditis.
— Good oral hygiene should be maintained and infectious diseases treated to reduce the risk of pathogens entering the bloodstream.
— It is important to inform doctors about the presence of artificial valves or other implants in order to receive timely prophylactic antibiotic therapy.
These measures can significantly reduce the risk of developing endocarditis in patients with predisposing factors and improve treatment outcomes.
