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.
