<unk>  hypertension is a pathophysiologic condition with many possible causes. Indeed, this condition frequently accompanies severe heart or lung conditions. A 1973 World Health Organization meeting was the first attempt to classify<unk>  hypertension by its cause, and a distinction was made between primary PH (resulting from a disease of the<unk>  arteries) and secondary PH (resulting secondary to other, non-vascular causes). Further, primary PH was divided into the "arterial plexiform", "veno-occlusive" and "thromboembolic" forms. In 1998, a second conference at Évian-les-Bains addressed the causes of secondary PH. Subsequent third, fourth, and fifth (2013) World Symposia on PAH have further defined the classification of PH. The classification continues to evolve based on improved understanding of the disease mechanisms. Most recently in 2015, the WHO guidelines were updated by the European Society of Cardiology (ESC) and European Respiratory Society (ERS). These guidelines are endorsed by the International Society for Heart and Lung Transplantation, and provide the current framework for understanding and treatment of<unk>  hypertension. Genetics Mutations in several genes have been associated with this condition these include bone morphogenetic protein receptor type 2 (BMPR2) and eukaryotic translation initiation factor 2 alpha kinase 4 gene (EIF2AK4).
