TODAY'S CHALLENGES IN THE DIAGNOSIS AND TREATMENT OF PULMONARY ARTERIAL HYPERTENSION

Abstract

Pulmonary hypertension (PH) is a condition in which high blood pressure in the pulmonary arteries is detected. Pulmonary arterial hypertension (PAH) includes a group of disorders with similar pulmonary vascular pathophysiological mechanisms and clinical characteristics. PAH affects about 5 % of all PH cases. Evidently, early diagnosis and treatment of PAH are vital. It may result in an improvement in long–term outcome. Diagnosis of PAH is often delay up to 3 years from the symptom. It is very often due to non–specific symptoms. However, because the disease presents with non specific symptoms, it often takes up to 3 years from the onset of the first symptoms.
