Overview
The four general categories of dyspnea are based on its causes: cardiac, pulmonary, mixed cardiac or pulmonary, and noncardiac or nonpulmonary. Sudden onset of dyspnea (acute dyspnea) is most typically associated with narrowing of the airways or airflow obstruction (bronchospasm), blockage of one of the arteries of the lung (pulmonary embolism), acute heart failure or myocardial infarction, pneumonia, or panic disorder. Long-standing dyspnea (chronic dyspnea) is most often a manifestation of chronic or progressive diseases of the lung and / or heart, such as COPD, which includes chronic bronchitis and emphysema.
Dyspnea also is experienced by individuals encountering high-altitude sickness (high-altitude pulmonary edema, [HAPE]). This is associated with rapid rate of mountain ascent and normally occurs during the first 1 to 3 days of achieving a high altitude. Dyspnea resolves with use of supplemental oxygen, rapid descent, and occasionally hyperbaric therapy.
