Paroxysmal nocturnal hemoglobinuria (PNH) may cause unpredictable episodes of acute red blood cell destruction (hemolysis). This occurs when a part of your immune system called complement attacks red blood cells that lack certain protective proteins.
Paroxysmal nocturnal dyspnea is usually caused by congestive heart failure, most commonly (but not always) in people who also have had episodes of dyspnea with exertion, or of orthopnea (shortness of breath when lying down). People who experience PND also usually have at least some edema (swelling) in their feet and legs.
