The pericardium is a membranous sac that surrounds the heart and performs protective and supportive functions. Diseases of the pericardium can lead to serious disturbances of cardiac function; therefore, timely diagnosis and appropriate treatment are of great clinical importance. The most common pericardial disorders include pericarditis, pericardial effusion, constrictive pericarditis, and related conditions. Management depends on the underlying cause and the stage of the disease.
Causes of pericardial diseases
Pericardial diseases may develop due to various factors. These include infections such as viral or bacterial illnesses. Autoimmune disorders, in which the immune system attacks pericardial tissues, are another important cause. Trauma or previous cardiac surgery, as well as primary heart diseases such as myocardial infarction or cardiac tumors, can also lead to pericardial involvement. Metabolic disorders, including chronic kidney disease, may provoke pericardial pathology as well.
Symptoms of pericardial diseases
Pericardial disorders may present with a range of clinical symptoms, including:
- Chest pain, often worsening with deep inspiration or in the supine position.
- Shortness of breath, which may increase during physical exertion or even at rest.
- Swelling of the legs and abdomen due to fluid accumulation.
- Fever and chills in inflammatory conditions.
- Fatigue, dizziness, and general weakness, which may indicate impaired circulation.
Treatment of pericardial diseases
The choice of treatment depends on the specific pericardial condition and the patient’s clinical status. The following therapeutic approaches may be applied:
- Pharmacological treatment. Anti-inflammatory therapy is the cornerstone of treatment and may include nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids. If the disease is caused by an infection, antibacterial or antiviral medications are prescribed. Diuretics are used to reduce fluid overload, and antihypertensive agents may be required in patients with arterial hypertension. Colchicine is widely used in acute and recurrent pericarditis for its anti-inflammatory effect, as it inhibits key inflammatory pathways and reduces the risk of relapse.
- Pericardial drainage. In cases of significant pericardial effusion, pericardiocentesis is performed to remove excess fluid, relieve cardiac compression, and improve heart function.
- Surgical intervention. Severe or chronic cases may require surgery. Pericardiectomy, which involves partial or complete removal of the pericardium, is indicated in chronic or constrictive pericarditis. Pericardiotomy may also be performed to provide access to inflamed or affected areas.
- Supportive therapy. Patients with pericardial diseases often require long-term cardiovascular monitoring. Medications may be prescribed to control blood pressure, manage fluid balance, and stabilize heart rhythm.
Prognosis and prevention
The prognosis of pericardial diseases largely depends on their etiology and the timeliness of treatment. Many patients recover fully with appropriate therapy, while chronic forms may require long-term follow-up and management.
Preventive measures include regular medical check-ups, especially for individuals with chronic conditions such as hypertension, diabetes, or underlying heart disease. Prompt treatment of infections and inflammatory processes is essential to prevent their spread to the pericardium. A healthy lifestyle, including balanced nutrition and regular physical activity, also plays an important role in prevention.
Diagnosis and treatment of pericardial diseases are available in leading clinics in Belarus, where experienced specialists apply modern diagnostic tools and therapeutic approaches to ensure effective care and prevention of complications.
