[Acute and chronic-constrictive pericarditis].
Acute pericarditis is an inflammatory disease of the pericardium of variable etiology. A viral infection may sometimes precede symptoms but frequently the etiology re-mains unknown (idiopathic pericarditis). The disease is typically associated with left-sided chest pain and ECG abnormalities mimicking acute myocardial infarction. At physical examination the characteristic finding is a pericardial friction rub. A pericardial effusion of varying extent may be present or develop in the course of the disease. Pericardial tamponade, which may develop insidiously, represents a life-threatening complication. Pathophysiologically, filling of the cardiac chambers is impeded resulting in orthopnea, tachycardia, and eventually shock. Emergency pericardiocentesis is the treatment of choice. Constrictive pericarditis is the result of a chronic inflammation of the pericardium. Clinically it is characterized by dyspnea during exercise, symptoms of right heart failure and typical hemodynamic findings. Treatment primarily includes surgical removal of the thickened pericardium.
