title: Classification of Pulmonary Hypertension.
abstract: The classification of pulmonary hypertension (PH) is an attempt to define subtypes of PH based on clinical presentation, underlying physiology, and treatment implications. Five groups of PH have been defined, and the classification scheme has been refined over the years to guide clinicians in the diagnosis and management of PH. Understanding the classification of PH is paramount before embarking on a work-up of patients with PH or suspected PH because treatment and outcome can vary greatly.
