A breath-robbing disease that’s hard on the heart

About one in eight adults over age 45 has chronic obstructive pulmonary disease (COPD). COPD refers to several lung-damaging conditions, particularly emphysema and chronic bronchitis, that cause coughing and breathlessness. But many people don’t know much about COPD, which is largely caused by cigarette smoking and may be mistaken for heart disease. Anyone with symptoms of COPD should be evaluated by a physician. People who have heart disease who have ever smoked or lived with a smoker should be tested for COPD.
