How does tuberculosis cause pericarditis?

How does tuberculosis cause pericarditis?

Tuberculous pericarditis arises most frequently by direct spread from involved mediastinal lymph nodes or adjacent pulmonary lesions and from hematogenous seeding. Pericardial effusion is the most common clinical manifestation. Pericardial effusions usually form slowly.

Can tuberculosis cause pericardial effusion?

The pericardial fluid is bloodstained in 80% of cases of tuberculous pericarditis. However, because malignant disease and the late effects of penetrating trauma may also cause bloody pericardial effusion, confirmation of TB as the cause is important.

What is tuberculous pericarditis?

Tuberculous pericarditis is an important complication of tuberculosis (TB); the diagnosis can be difficult to establish and is often delayed or missed, resulting in late complications such as constrictive pericarditis and increased mortality [1]. Options for management of advanced disease are limited.

How does TB cause constrictive pericarditis?

Persistent tuberculous pericarditis will lead to pericardial constriction due to chronic granulomatous inflammation of the pericardium with subsequent deposition of fibrinous strands, demonstrable on echocardiography [8].

Can TB cause cardiac tamponade?

Cardiac tamponade is an uncommon presenting symptom of TB, but is a life-threatening condition that may require acute treatment in intensive care unit. Special precautions should be taken in this setting to avoid the spread of the disease.

How does TB affect the heart?

Cardiac tuberculosis causes: Inflammation around heart, which leads to chest pain and shortness of breath. If left undiagnosed and untreated, it can lead to complications and premature death as well.

How pericarditis is diagnosed?

The most common tests are: EKG (electrocardiogram): This detects and records your heart’s electrical activity, with certain EKG results suggesting pericarditis. Chest X-ray: A chest X-ray takes pictures of the inside of the chest, including your heart, lungs and blood vessels.

What are the types of pericarditis?

The main types of pericarditis include:

  • viral pericarditis.
  • bacterial pericarditis.
  • constrictive pericarditis.
  • post-heart attack pericarditis.
  • chronic effusive pericarditis.

How is pericarditis diagnosed?

What tests will be done to diagnose pericarditis?

  1. Chest X-ray to see the size of your heart and any fluid in your lungs.
  2. Electrocardiogram (ECG or EKG) to look for changes in your heart rhythm.
  3. Echocardiogram (echo) to see how well your heart is working and check for fluid (a pericardial effusion) around your heart.

What is cardiac tuberculosis?

Cardiac tuberculosis refers to the rare infection of the heart with Mycobacterium tuberculosis.

Who is at risk for pericarditis?

Pericarditis affects people of all ages, but men ages 16 to 65 are more likely to develop it. Among those treated for acute pericarditis, up to 30% may experience the condition again, with a small number eventually developing chronic pericarditis.
