What consequences can a thickened pericardium cause?

Thickening of the pericardium may lead to symptoms such as chest tightness, chest pain, and shortness of breath. Specific details are as follows:

Pericardial thickening refers to pathological changes in the pericardium—the double-layered sac surrounding the heart—commonly caused by infections, tumors, or metabolic disorders, and is most frequently seen in subacute and chronic pericarditis. Patients with typical pericarditis may experience symptoms including fever, cough, vomiting, and diarrhea. Acute pericardial thickening can present with chest pain, chest tightness, and difficulty breathing. Physical examination may reveal weakened apical impulse and tachycardia.

In addition to the aforementioned common symptoms, other manifestations such as pallor and palpitations may also occur. If a patient's symptoms are mild, specific treatment may not be necessary. However, it is important to actively identify and treat the underlying cause—for example, administering anti-infective therapy in cases of infectious pericarditis. During treatment, patients should rest in bed, maintain a light diet, consume more green vegetables, ensure adequate sleep, and avoid prolonged late-night hours. If any discomfort arises, prompt medical attention is recommended to prevent disease progression.
