The introduction of targeted PAH therapy consisting of prostacyclin and its analogs, endothelin antagonists, phosphodiesterase-5 inhibitors, and now a soluble guanylate cyclase activator have increased therapeutic options and potentially reduced morbidity and mortality; yet, none of the current therapies have been curative. Current clinical management of PAH has become more complex given the focus on early diagnosis, an increased number of available therapeutics within each mechanistic class, and the emergence of clinically challenging scenarios such as perioperative care. Efforts to standardize the clinical care of patients with PAH have led to the formation of multidisciplinary PAH tertiary care programs that strive to offer medical care based on peer-reviewed evidence-based, and expert consensus guidelines. Furthermore, these tertiary PAH centers often support clinical and basic science research programs to gain novel insights into the pathogenesis of PAH with the goal to improve the clinical management of this devastating disease. In this article, we discuss the clinical approach and management of PAH from the perspective of a single US-based academic institution. We provide an overview of currently available clinical guidelines and offer some insight into how we approach current controversies in clinical management of certain patient subsets. We conclude with an overview of our program structure and a perspective on research and the role of a tertiary PAH center in contributing new knowledge to the field.<\/jats:p>","DOI":"10.1161\/circresaha.115.303827","type":"journal-article","created":{"date-parts":[[2014,6,20]],"date-time":"2014-06-20T14:52:25Z","timestamp":1403275945000},"page":"131-147","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":53,"title":["Current Clinical Management of Pulmonary Arterial Hypertension"],"prefix":"10.1161","volume":"115","author":[{"given":"Roham T.","family":"Zamanian","sequence":"first","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristina T.","family":"Kudelko","sequence":"additional","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yon K.","family":"Sung","sequence":"additional","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vinicio","family":"de Jesus Perez","sequence":"additional","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliana","family":"Liu","sequence":"additional","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edda","family":"Spiekerkoetter","sequence":"additional","affiliation":[{"name":"From the Division of Pulmonary and Critical Care Medicine and Vera Moulton Wall Center for Pulmonary Vascular Disease, Stanford Cardiovascular Institute, Stanford University School of Medicine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.10.029"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.10.031"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201311-1954ST"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.10.032"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11-1460"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00057010"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-115-5-343"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp022"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1159\/000334431"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199602013340504"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.122.5.1668"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.4103\/2045-8932.97592"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(11)60966-X"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/354325"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.01.004"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1161\/circulationaha.104.503540"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pupt.2014.01.004"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1213917"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1209655"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00116313"},{"key":"e_1_3_4_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.10.034"},{"key":"e_1_3_4_23_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-149-8-200810210-00004"},{"key":"e_1_3_4_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2010.01.027"},{"key":"e_1_3_4_25_2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200603-358OC"},{"key":"e_1_3_4_26_2","first-page":"190","article-title":"Pulmonary arterial hypertension.
