PE occurs when blood clot breaks loose from a deep vein in the body, travels through the bloodstream, and lodges in an artery in the lungs. If left untreated, PE can cause heart attack, shock, stroke, or death. PE can also develop directly in the small blood vessels of the lungs, even if there are no clots in the arms or legs.
