The differential diagnosis of tuberculous pericarditis requires differentiation from other types of pericardial inflammation, such as bacterial pericarditis and nonspecific infections that lead to cellular inflammation of the pericardium. In addition to infections that can cause pericarditis, other infectious diseases such as subacute endocarditis and infections caused by other microbes can also lead to pericarditis. Furthermore, some rheumatic autoimmune diseases can also present with pericarditis. It is necessary to perform pericardiocentesis and fluid examination to determine the specific cause.

What are the clinical considerations for acute pericarditis?

The treatment and prognosis of acute pericarditis depend on the cause, as well as early diagnosis and correct treatment. For various types of pericarditis, such as those presenting with tamponade syndrome, pericardiocentesis should be performed to relieve symptoms. Tuberculous pericarditis, if not actively treated, can evolve into chronic constrictive pericarditis. Patients with acute nonspecific pericarditis and post-cardiac injury syndrome may experience recurrent pericarditis after their initial episode, which is the most challenging complication of acute pericarditis. Clinically, it presents similarly to acute pericarditis, with recurrent episodes months to years after the initial onset, accompanied by severe chest pain. Most patients can be treated again with high doses of non-steroidal anti-inflammatory drugs, slowly tapering to normal over several months. If ineffective, corticosteroid therapy may be administered. (Medications should be used under the guidance of a doctor according to specific circumstances.)

What are the symptoms of pericarditis?

Fibrinous pericarditis is primarily characterized by precordial pain, similar to that seen in acute nonspecific pericarditis and infectious pericarditis. Tuberculous or neoplastic pericarditis that develops slowly may not show obvious pain symptoms. The nature of the pain can be sharp and related to respiratory movements. It is often exacerbated by coughing, deep breathing, changing body position, or swallowing. The pain is located in the precordial area and may radiate to the neck, left shoulder, left arm, and left scapula, and can also reach the upper abdomen. The pain can be compressive and located behind the sternum. The most prominent symptom of exudative pericarditis is dyspnea, which may be associated with bronchopulmonary compression and pulmonary congestion. In severe cases of dyspnea, the patient may sit up to breathe, leaning forward, with rapid and shallow breathing and pale complexion. There may be hepatomegaly, as well as compression of the trachea and esophagus causing dry cough, hoarseness, and difficulty swallowing. Rapid pericardial effusion can lead to acute cardiac tamponade, presenting with significant tachycardia and decreased blood pressure. Reduced pulse pressure and increased venous pressure, if the cardiac output significantly drops, can lead to shock. If the fluid accumulates slowly, it could lead to subacute or chronic cardiac tamponade, characterized by systemic venous congestion and distended jugular veins.

Is pericarditis serious?

Pericarditis refers to a group of diseases mainly characterized by inflammation and effusion of the pericardium. The severity of pericarditis depends on the condition of the disease. Firstly, if the inflammation and effusion of the pericardium are not severe, patients often experience symptoms such as chest tightness or chest pain. In general, this type of pericarditis is not considered severe. Secondly, if the inflammation and effusion of the pericardium are more pronounced, it can lead to pericardial effusion, especially in cases of large amounts of pericardial fluid. At this time, the condition is often quite serious, and it is essential to undergo formal treatment under the guidance of a doctor, including pericardial drainage therapy.

acute pericarditis clinical manifestations

The clinical manifestations of acute pericarditis include symptoms and signs. The symptoms of acute pericarditis are pain behind the sternum and in the precordial region, which often occurs during the fibrinous exudative phase of inflammation. The pain can radiate to the neck, left shoulder, left arm, and even the upper abdomen. The nature of the pain is sharp, related to respiratory movements. As the condition progresses, the pain can disappear and be replaced by difficulty breathing. Some patients may develop significant pericardial effusion leading to cardiac tamponade, resulting in symptoms such as difficulty breathing, edema, and other related symptoms. During acute pericarditis, the most diagnostically valuable sign is the pericardial friction rub, typically located in the precordial area. A typical friction rub can be heard consistent with atrial contraction, ventricular contraction, and ventricular relaxation, known as a triphasic friction rub, and so on.

Is tuberculous pericarditis hereditary?

Tuberculous pericarditis is an infectious disease, not a hereditary disease. Most cases are due to tuberculosis of the lungs, after which the tuberculosis bacteria enter the bloodstream and cause tuberculous pericarditis in the pericardium. Tuberculous pericarditis is curable. If it is confirmed to be tuberculous pericarditis, it is necessary to start anti-tuberculosis treatment as soon as possible. It may also be necessary to combine some corticosteroids for treatment. With standardized anti-tuberculosis and symptomatic supportive treatment, it can generally be completely cured. Analysis should be tailored to the actual situation.
