    • Irreversible lung damage and permanently reduced lung function because of severe fibrosis and impaired ability to oxygenate the blood during normal breathing.
    • Pulmonary hypertension due to damage of blood vessels in the lungs.
    • Heart failure because inflammation makes it harder for the heart to pump blood to and through the lungs.
