Insights
Obesity and blood pressure trajectories significantly impact heart failure (HF) risk. Identifying distinct patterns in body mass index (BMI) and systolic blood pressure (SBP) can improve HF risk prediction.
Area of Science:
- Cardiology
- Metabolic Health
- Genetics
Background:
- Obesity is a significant risk factor for heart failure (HF).
- The interplay between dynamic changes in body mass index (BMI) and systolic blood pressure (SBP) and HF risk in obese individuals requires further clarification.
- Understanding these dynamics is crucial for advancing precision medicine in HF prevention.
Purpose of the Study:
- To identify distinct joint longitudinal trajectories of BMI and SBP in individuals with obesity.
- To evaluate the association between these identified trajectories and the risk of overall HF and its subtypes.
- To explore potential underlying genetic and proteomic mechanisms contributing to differential HF risk.
Main Methods:
- Utilized group-based multi-trajectory modeling on 14,469 UK Biobank participants with BMI ≥ 30.
- Applied inverse probability of treatment weighting to assess associations between trajectory groups and HF outcomes.
- Investigated genetic susceptibility using polygenic risk scores (PRS) and explored plasma proteomic characteristics.
Main Results:
- Identified four distinct BMI-SBP trajectory patterns: MOMH, SOHN, MOHN, and MOMSH.
- The SOHN trajectory (severe obesity with high-normal BP progression) showed the highest overall HF risk (HR=3.76).
- Specific trajectories were linked to increased risk for HF with preserved ejection fraction (HFpEF) and differential genetic/proteomic profiles.
Conclusions:
- Dynamic trajectory-based phenotyping provides a nuanced understanding of obesity-BP patterns and their association with HF risk.
- This approach offers a more informative framework for HF risk assessment compared to static indicators.
- Identified subtypes exhibit distinct nutritional, metabolic, and genetic profiles, paving the way for personalized HF prevention strategies.
Abstract:
Background: Obesity is an important risk factor for heart failure (HF). The dynamic heterogeneity of HF risk and its interaction with blood pressure changes among individuals with obesity remain unclear. This study aimed to improve risk assessment and support precision medicine by evaluating joint longitudinal trajectories of body mass index (BMI) and systolic blood pressure (SBP). Methods: We included 14,469 participants with BMI ≥ 30 from the UK Biobank. Group-based multi-trajectory modeling identified joint BMI-SBP trajectories. After inverse probability of treatment weighting, associations between trajectory groups and overall HF and its subtypes were evaluated, and potential mechanisms were explored using polygenic risk score (PRS) and plasma proteomic characteristics. Results: Four distinct trajectory patterns were identified: mild obesity with mild hypertension trajectory (MOMH), severe obesity with high-normal blood pressure progression trajectory (SOHN; BMI approximately 37.0 kg/m2, SBP increasing from approximately 131 to 138 mmHg), moderate obesity with high-normal blood pressure progression trajectory (MOHN; BMI approximately 33.0 kg/m2, SBP increasing from approximately 132 to 139 mmHg), and mild obesity with moderate-to-severe hypertension improvement trajectory (MOMSH). The SOHN group exhibited the highest risk of overall HF (HR=3.76). MOMSH and MOMH were associated with higher HFpEF risk (HRs: 2.68-2.70), whereas MOHN showed the lowest HF risk (HR = 1.82). These trajectory-based subtypes displayed heterogeneity in genetic susceptibility and plasma proteomic characteristics. Conclusions: Dynamic trajectory-based phenotyping identifies distinct obesity-BP patterns associated with differential HF risk and distinct nutritional and metabolic profiles, offering a more informative framework than static indicators for risk assessment.
