Pulmonary Arterial Hypertension (PAH) is a condition characterized by elevated blood pressure in the arteries carrying blood from the heart to the lungs. This narrowing or blockage of pulmonary vessels disrupts normal blood flow, increasing pressure on the right side of the heart. Over time, this added strain can cause heart failure if untreated. PAH can develop progressively or be managed with appropriate therapy, depending on its type. Recognizing symptoms early and seeking medical advice are crucial for effective treatment.
What Causes Pulmonary Arterial Hypertension?
The heart's right ventricle pumps blood through the pulmonary artery into the lungs. In PAH, changes in the pulmonary artery cells lead to thickening and inflammation, constricting blood flow. PAH is classified into five groups based on its underlying cause, such as genetic factors, drugs, or other health conditions.
Diagnosis and Management
After diagnosis, the severity of PAH can be categorized into four classes. Class I shows no symptoms during physical activity. Class II presents with fatigue and breathlessness during activity. Class III patients experience symptoms with minimal exertion, while Class IV individuals have symptoms even at rest. Treatment options include vasodilators like Flolan and Veletri, which help relax blood vessels and reduce symptoms. Additional medications such as Revatio and Cialis may also improve blood flow but can cause side effects like visual disturbances.
