Why the study?
There is considerable variability in the clinical presentation of patients categorized with idiopathic pulmonary arterial hypertension.
Does cluster analysis identify distinct phenotypes with different survival and treatment responses in patients with idiopathic pulmonary arterial hypertension?
Does cluster analysis identify distinct phenotypes with different survival and treatment responses in patients with idiopathic pulmonary arterial hypertension?
Patients diagnosed with idiopathic pulmonary arterial hypertension are a heterogeneous population that can be classified into three distinct phenotypes with significantly different clinical presentations, treatment responses, and survival rates.

IPAH cluster phenotypes associate with graded survival; hypothesis-generating for phenotyping but requires validation before clinical use.
