Unlocking Predictive Power: TyG Index and Derivatives in Hypertension Mortality
Our advanced machine learning analysis of NHANES data reveals the critical role of triglyceride-glucose (TyG) index and its obesity-related derivatives in forecasting all-cause and cardiovascular mortality among hypertensive patients. This innovative approach provides a robust tool for enhanced risk stratification and proactive intervention strategies.

The Hypertension-Insulin Resistance Challenge
Hypertension (HTN) is a pervasive global health concern, directly contributing to cardiovascular disease (CVD) and mortality. Despite widespread efforts, controlling HTN remains a significant public health challenge, with prevalence projected to increase. Insulin resistance (IR) plays a pivotal role in HTN-related metabolic dysfunction, exacerbating CVD risk. Traditional IR assessment methods are often complex and costly, limiting their broad clinical application. The triglyceride-glucose (TyG) index and its obesity-related derivatives (TyG-BMI, TyG-WC, TyG-WHtR) have emerged as accessible and reliable markers for IR, offering a promising avenue for improved risk stratification in hypertensive populations.
Advanced Analytics for Predictive Modeling
This study utilized data from 9,432 hypertensive participants in the National Health and Nutrition Examination Survey (NHANES) from 1999–2018. The robust methodology included Cox proportional hazards models to explore mortality risk, restricted cubic splines for non-linear relationships, and a suite of state-of-the-art machine learning techniques. Feature selection using LASSO and Boruta algorithms identified key predictors, ensuring model efficiency. Multiple machine learning algorithms (logistic regression, k-nearest neighbors, Naive Bayes, SVMs, random forests, XGBoost) were evaluated with fivefold cross-validation (5x5) to determine the optimal model performance based on AUROC, ensuring reliable and validated results.
TyG Indices: Potent Predictors of Mortality
Our analysis consistently demonstrated that the TyG index and its obesity-related derivatives are independent predictors of both all-cause and cardiovascular mortality in hypertensive patients. Notably, TyG-WHtR exhibited the strongest association. Each 1-unit increase in TyG-WHtR was linked to a 41.7% higher risk of all-cause mortality and a 48.1% higher risk of cardiovascular mortality (P<0.001 for both). L-shaped relationships were observed between these indices and mortality outcomes, indicating a nuanced, non-linear risk profile. The integration of these indices into predictive models modestly yet significantly improved prediction performance, enhancing risk stratification.
Towards Precision Medicine in Hypertension Management
The findings advocate for the clinical utility of the TyG index and its derivatives as accessible and powerful tools for risk assessment. By integrating these markers into machine learning frameworks, healthcare providers can achieve earlier and more precise identification of hypertensive patients at the highest risk for adverse outcomes. This precision enables the timely implementation of targeted interventions, optimizing patient management and resource allocation. Such an approach moves healthcare closer to a precision medicine model, potentially reducing the substantial global burden of HTN-related morbidity and mortality.

Enhanced Risk Stratification for Hypertensive Patients
Our study demonstrates that incorporating the TyG index and its derivatives into machine learning models significantly enhances risk stratification for both all-cause and cardiovascular mortality in hypertensive patients. The TyG-WHtR, in particular, stands out as a strong independent predictor. Machine learning techniques excel at identifying intricate, non-linear patterns, providing more precise risk assessments than traditional methods. This allows for earlier identification of high-risk individuals, enabling targeted interventions and potentially improving patient outcomes and resource allocation in clinical settings. This approach aligns with the principles of precision medicine, offering a robust tool for managing HTN-related metabolic dysfunction.
