Which condition usually has no dependent edema?

Explanation:
Dependent edema appears when venous return is impeded and hydrostatic pressure builds up in the legs and other dependent areas, which is a common consequence of systemic venous congestion from congestive heart failure. COPD, including emphysema and chronic bronchitis, is a lung disease; by itself it does not cause this pattern of systemic venous congestion. Only if COPD progresses to cor pulmonale with pulmonary hypertension would right-sided heart strain lead to edema, but that’s not the typical finding in COPD alone. Therefore, COPD usually has no dependent edema, whereas heart failure is classically associated with it.
