An Expanding Role of Biomarkers in Pulmonary Arterial Hypertension

Abstract

Background: Pulmonary Arterial Hypertension (PAH) is a chronic disease which may cause or result from multiple cardiopulmonary disorders. The disease has complex pathophysiological mechanisms and involves many systematic, cellular and molecular changes. Therefore, it is crucial to find out underlying mechanisms and detect biomarkers to achieve early and proper diagnosis, evaluating disease severity, for follow-up and monitor response to treatment. Many biomarkers for PAH have been investigated but yet no such biomarker has been found specific and easily accessible to use for the patients. This review aims to identify an expanding role of biomarkers in PAH.
