Complications
Many cases of pericarditis can resolve in several days or weeks. However, some forms of complications can happen:
– Tamponade pericarditis: This form happens when fluid building up in the pericardial sac prevents a complete fill of the heart. As a result, blood pressure can drop and the lungs can be congested. Typical symptoms include extreme dyspnea, lightheadedness, dizziness, and weakness.
– Constrictive pericarditis: This type happens when chronic inflammation of the pericardium causes stiffness and reduces its elasticity. Symptoms are quite similar to those of tamponade pericarditis but with a more gradual progression.
– Chronic pericarditis: When inflammation does not improve in several weeks, it leads to chronic pericarditis. It would be related to all the signs of acute form and followed by especially large pericardial effusions. [5]
