What is the difference of PND in CHF and COPD?

Hello Anonymous,

Paroxysmal nocturnal dyspnea is respiratory distress that awakens patients from sleep, related to posture (especially reclining at night), attributed to congestive heart failure with pulmonary edema or sometimes to chronic pulmonary disease.

It is a sign of heart failure.

Heart failure in the left ventricle is the most common form of heart failure. Left-sided heart failure is most often caused by high blood pressure or coronary artery disease. COPD and left-sided heart failure are not directly related. However, the two conditions may influence each other.

So, to answer your question, there is no difference because the symptoms of PND are the same in the presence of both conditions. Most often, CHF is a consequence of COPD.
