Machine learning-based clustering in idiopathic PAH: mortality is driven by hemodynamic severity in vascular phenotype vs. frailty in cardiometabolic co-morbidity group
Idiopathic pulmonary arterial hypertension (IPAH) is characterized by significant clinical heterogeneity. This study aimed to identify distinct patient phenotypes using machine learning-based cluster analysis and to evaluate their differences in therapeutic response and long-term survival. A total of 297 p...
