Pulmonary Hypertension Scholarly Peer-review Journal
Pulmonary
hypertension occurs during the pressure in the blood vessels that carry blood from your heart to your lungs is higher than normal. One of the type of pulmonary
hypertension is pulmonary arterial
hypertension (PAH). Pulmonary
hypertension can occurs on its own or be give rise to another disease or condition. In the United States, the most familiar cause of pulmonary
hypertension is left heart disease. Other types can cause pulmonary
hypertension include red blood cell disease; pulmonary embolus, which may be a sort of venous thromboembolism; and chronic obstructive
pulmonary disease (COPD). The increased pressure in the blood vessels of the lungs means that your heart has to work harder to pump blood into the lungs. This can cause symptoms such as shortness of breath, chest pain, and lightheadedness. If left untreated, the increased pressure can damage your heart. This may lead to critical or life-threatening complications, such as
heart failure or arrhythmias, which are irregular heart rhythms. The most common symptoms of PH also can be caused by other more common medical problems, like
asthma or chronic obstructive
pulmonary disease (COPD). Therefore, diagnosing PH is difficult and requires a specialist. Physical examination signs can include visible or enlarged veins on the side of the neck, irregular heart sounds or swelling within the abdomen or legs and feet.
