Why the study?
Hypertension is heterogeneous in presentation and treatment response, and identifying distinct subphenotypes may improve understanding of underlying mechanisms and guide more precise treatment or public health initiatives.
Population
40,686 adult Floridians with newly diagnosed HTN
Design
Cohort study using hierarchical clustering unsupervised machine learning
Key result
Unsupervised machine learning identified 5 distinct hypertension subphenotypes varying in demographic, socioeconomic, and risk profiles among 40,686 newly diagnosed adult patients.

Does not support immediate changes in hypertension care; leaves open whether subphenotypes predict outcomes or guide therapy.
Observational (n=40,686)
Yes
Unsupervised machine learning identified five distinct subphenotypes of newly diagnosed hypertension, highlighting significant heterogeneity in demographic, clinical, and socioeconomic profiles.
Hall et al. (2025) conducted an observational in Newly diagnosed hypertension (n=40,686). Hierarchical clustering (unsupervised machine learning) was evaluated on Identification of distinct subphenotypes within the hypertension population. Unsupervised machine learning identified 5 distinct hypertension subphenotypes varying in demographic, socioeconomic, and risk profiles among 40,686 newly diagnosed adult patients.
