The immune system response that leads to Dressler's syndrome might also cause fluid to accumulate in the membranes around your lungs (pleural effusion).

Rarely, Dressler's syndrome can cause more-serious complications, including:

  • Cardiac tamponade. Inflammation of the pericardium can cause fluids to accumulate in the sac (pericardial effusion). The fluid can put pressure on the heart, forcing it to work harder and reducing its ability to pump blood efficiently.
  • Constrictive pericarditis. Recurring or chronic inflammation can cause the pericardium to become thick or scarred. The scarring can reduce the heart's ability to pump blood efficiently.
