Course ID: 2816

CEU Information


While idiopathic pulmonary arterial hypertension is a rare disease, general PH often complicates other pulmonary and cardiovascular diseases and is a relatively common entity. Significant differences and similarities exist between the five groups of PH, as defined by the World Health Organization. However, without clinical context and noninvasive tests, there is no sufficient evidence to provide an accurate diagnosis. This class will focus on the how to differentiate between the various PH groups and how to utilize integrative tests to produce an accurate and effective diagnosis and treatment plan.
