Paroxysmal nocturnal hemoglobinuria or PNH is a rare and chronic disease that results in an abnormal breakdown of red blood cells. PNH is due to a spontaneous genetic mutation that causes red blood cells to be deficient in a protein, leaving them fragile.
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.
