High Quality Content by WIKIPEDIA articles! Cardiac asthma is a medical symptom, also known as paroxysmal dyspnea or paroxysmal nocturnal dyspnea (PND). It is defined as sudden, severe shortness of breath at night that awakens a person from sleep, often with coughing and wheezing. It is most closely associated with congestive heart failure. PND commonly occurs several hours after a person with heart failure has fallen asleep. PND is often relieved by sitting upright, but not as quickly as simple orthopnea. Also unlike orthopnea, it does not develop immediately upon lying down. PND is caused by increasing amounts of fluid entering the lung during sleep and filling the small, air-filled sacs (alveoli) in the lung responsible for absorbing oxygen from the atmosphere. This fluid typically rests in the legs, filling interstitial spaces in the peripheral vascular system (peripheral edema) during the day when the individual is upright. At night, when recumbent for an extended period, this fluid is reabsorbed, increasing total blood volume and blood pressure, leading to pulmonary hypertension in people with underlying left ventricular dysfunction.
