Liu, M.D., a study coauthor, pulmonologist, and an assistant professor of medicine at the University of ...

Researchers already knew that extra mucus accumulating in smaller airways among people with COPD was associated with an increased risk for ...
Sudden, or acute, heart failure can be caused by an injury or infection that damages your heart, a heart attack, or a blood clot in your lung. To understand heart failure, it helps to know how the heart works. The right side of your heart gets oxygen-low blood from your body. It pumps the blood to your lungs to pick up oxygen.
Short-acting bronchodilators last about 4 to 6 hours. If your COPD is moderate or severe, you may need long-acting bronchodilators that last about 12 hours or more. You take these every day. If your COPD is severe or your symptoms flare up often, your provider may prescribe a combination of bronchodilators and an inhaled steroid.
