Pericarditis includes primary infectious pericarditis, as well as non-infectious pericarditis caused by related diseases, such as tumors, metabolic diseases, autoimmune diseases, and uremia. Based on the progression of the condition, pericarditis can also be divided into acute pericarditis, with or without pericardial effusion, chronic pericarditis, adhesive pericarditis, subacute exudative constrictive pericarditis, and chronic constrictive pericarditis. Clinically, acute pericarditis and chronic constrictive pericarditis are the most common.

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.

Constrictive pericarditis clinical manifestations

Patients with constrictive pericarditis often have a history of pericarditis, pericardial effusion, malignant tumors, and other diseases. Some patients have an insidious onset with no obvious clinical symptoms in the early stages. The main symptoms can include palpitations, exertional dyspnea, decreased exercise tolerance, fatigue, enlarged liver, pleural effusion, abdominal effusion, and edema of the lower limbs. Patients with constrictive pericarditis commonly present with elevated jugular venous pressure, and often have a reduced pulse pressure. Most patients exhibit a negative apical beat during systole, with a commonly faster heart rate. The rhythm can be sinus, atrial, or ventricular, with premature contractions possible, as well as Kussmaul's sign. In the late stages, muscle atrophy, cachexia, and severe edema can occur.

Early symptoms of acute pericarditis

The early symptoms of acute pericarditis are pain, which is located behind the sternum or in the precordial area, typically seen in the fibrin exudative type of inflammation. This pain arises from the friction between the visceral pericardium and the parietal pericardium. The nature of the pain is very sharp and related to respiratory movement, commonly exacerbated by coughing, deep breathing, or swallowing. The pain can radiate to the neck, left shoulder, and left arm. As fluid accumulates in the pericardium and the two layers of the pericardium separate, the pain may decrease or disappear.

Treatment of constrictive pericarditis

Constrictive pericarditis refers to a disease in which the heart is surrounded by a densely thickened fibrotic or calcified pericardium, restricting ventricular diastolic filling and producing a series of circulatory disorders, typically chronic in nature. In China, the most common cause of constrictive pericarditis is tuberculosis. Constrictive pericarditis is a progressive disease, and most patients will develop chronic constrictive pericarditis. At this stage, pericardiectomy is the only effective treatment method. It should be performed early to avoid complications such as cardiac cachexia, severe liver dysfunction, and myocardial atrophy, with surgery usually carried out after controlling the pericardial infection. For tuberculosis patients, anti-tuberculosis treatment should continue for one year after surgery.

Symptoms of acute pericarditis

Acute pericarditis is an acute inflammatory disease of the visceral and parietal layers of the pericardium, with the most common cause being viral infections. The hallmark of acute pericarditis is pain in the precardiac area behind the sternum. The nature of the pain is very sharp, typically occurring during the fibrinous exudation phase of inflammatory changes, caused by friction between the visceral and parietal layers of the pericardium. The pain can radiate to the neck, left shoulder, and even the upper abdomen. It is associated with respiratory movements and often worsens with coughing, deep breathing, or changing body positions. When fluid exudes into the pericardium, separating the visceral and parietal layers, the patient's pain may decrease or disappear. However, some patients may experience symptoms such as breathing difficulties and edema due to cardiac tamponade.
