Abstract

Cardiometabolic diseases (CMDs) often manifest in the form of cardiometabolic multimorbidity. Traditional risk assessment methods that rely on single biomarkers fail to adequately characterise the heterogeneity among patients across various subtypes. This study seeks to utilise routine biomarkers to identify clinical subtypes with unique characteristics, thereby improving risk assessment.
We included 337 334 UK Biobank participants without type 2 diabetes (T2D), ischaemic heart disease (IHD) or stroke at baseline. Multi-task Deep LASSO selected 12 variables for K-means clustering. Multi-state Cox models assessed transitions to first cardiometabolic disease (FCMD), cardiometabolic multimorbidity (CMM) and death. Analyses of 251 plasma metabolic measures and circulating proteins characterised molecular correlates; metabolite panels were evaluated in held-out testing.
Four risk-informed phenotypes were identified: metabolically healthy (MH), older cardio-renal-metabolic (OCRM), lean hypercholesterolaemia (LHC) and early-onset metabolic syndrome (EO-MetS). During a median follow-up of approximately 13 years, OCRM showed the highest FCMD and FCMD-to-CMM risks. In primary models, OCRM and EO-MetS showed strong T2D associations, whereas LHC showed stronger relative associations with IHD and stroke than with T2D. Age adjustment attenuated several OCRM and LHC associations, particularly with IHD and stroke; T2D associations remained largely unchanged. Phenotypes exhibited differing metabolic profiles, and exploratory decomposition showed statistical overlap with phenotype-outcome associations without establishing causality. Protein enrichment highlighted complement/coagulation and vascular-remodelling processes. Metabolite panels modestly improved discrimination beyond full clinical models, increasing the 10-year CMM area under the receiver operating characteristic curve from 0.834 to 0.848; phenotype membership added little further improvement.
Routine biomarker-derived subtypes showed distinct cardiometabolic trajectories and multi-omic profiles. These risk-informed phenotypes support exploratory description of cardiometabolic heterogeneity, pending external validation.
