1. Respiratory causes

• Asthma
• Acute exacerbation of chronic obstructive pulmonary disorder (COPD)
• Pneumonia
• Pulmonary embolism
• Lung malignancy
• Pneumothorax, or aspiration

2. Cardiovascular causes

• Congestive heart failure
• Pulmonary edema
• Acute coronary syndrome
• Pericardial tamponade
• Valvular heart defect
• Pulmonary hypertension
• Cardiac arrhythmia
• Intracardiac shunting

3. Systemic Causes

• Anemia
• Acute renal failure
• Metabolic acidosis
• Thyrotoxicosis
• Cirrhosis of the liver
• Anaphylaxis
• Sepsis
• Angioedema
• Epiglottitis

The most common cause of dyspnea on exertion (DOE) is congestive heart failure (CHF).
