Sleep disordered breathing and chronic obstructive pulmonary disease: a narrative review on classification, pathophysiology and clinical outcomes. Repeated injury and repair leads to structural and physiologic changes. Chronic obstructive pulmonary disease (COPD) kills more than 3 million people worldwide every year. Early in the disease, people with COPD may feel short of breath when they exercise. Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a long-term lung disease that makes it hard to breathe.
