This is a question that only your doctor can address specifically for you. You may have PH if you have any of the following symptoms:
  • Unexplained difficulty breathing or shortness of breath (also known as dyspnea)
  • Chest pain
  • Inability to exercise
  • Faintness or passing out (also known as syncope) 
You may have PH if you have a family history of PH in a close relative (parents, siblings, children).
You may have PH if you already have a condition of the heart or lungs or another medical condition that can cause PH. These include:
  • Heart disease, such a heart failure
  • Lung disease, such as emphysema
  • A history of pulmonary embolism
  • Connective tissue diseases such as scleroderma (also known as CREST)
  • Infection with HIV
  • Severe liver disease, such as cirrhosis
  • Use of certain medications, such as appetite-suppressant medications for weight loss (also known as anorexigens) or recreational drugs (like cocaine)
