What are the common causes of constrictive pericarditis?

Constrictive pericarditis may be caused by viral infection, acute pericarditis, acute myocardial infarction, etc. The specific analysis is as follows:

Viral infection: If the patient is infected with pericarditis caused by viruses such as coxsackie virus, herpes virus, adenovirus, Echo virus, etc., it will lead to pericardial fibrosis and calcification, causing constrictive pericarditis.

Acute pericarditis: Acute pericarditis will lead to pericardial tissue scar formation, entwining the heart, limiting the normal operation of the heart, leading to cardiac relaxation limitation, causing reduced cardiac output, leading to constrictive pericarditis

. Acute myocardial infarction: Patients with acute myocardial infarction due to necrosis of some myocardial tissues, resulting in calcification of necrotic tissue fibers, causing pericardial adhesion, thickening, calcification, leading to constrictive pericarditis.
