Orthopnea is dyspnea that is worse when lying flat. This is a common characteristic of CHF, and it occurs in very advanced stages of COPD.
Dyspnea (shortness of breath), an intolerance to physical activity, and weariness are all symptoms of congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD), respectively. Both develop over time and usually affect smokers who are over 60. There are ways to distinguish between the two to establish whether you have COPD or CHF, but they can also coexist.
