A Literature Review of Pulmonary Arterial Hypertension (PAH)

Abstract

In 1891, German doctor E. Romberg was the first to report PAH. It is widespread throughout the world, but it is particularly problematic in India and other developing countries. Pulmonary arterial hypertension (PAH) is characterised by an increase in pulmonary arterial pressure as well as the emergence of progressive symptoms, such as a loss of functional ability, shortness of breath, and fatigue. Blood flows from the right side of the heart to the lungs through the pulmonary arteries. Pulmonary arterial pressure refers to the pressure in the arteries of the lungs (PAH). It necessitates immediate treatment because high blood pressure in the lungs causes the right side of the heart to work much harder, increasing the risk of heart failure. This article aimed to provide brief information about the prevalence, pathology, classification, and different therapies of PAH. � 2022 Bentham Science Publishers.
