What does this research mean for the field?

Obesity is associated with an increased risk of degenerative valvular heart disease, predominantly aortic stenosis, even in the absence of metabolic dysfunction, with concomitant metabolic abnormalities further compounding this risk. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the relationship between distinct metabolic obesity phenotypes and the incidence of degenerative valvular heart disease, while investigating genetic and proteomic mechanisms.

Metabolically unhealthy obesity is linked to ~30% higher risk of degenerative VHD.

Q: What is the clinical evidence from this study?

Study design: Cohort. Population: Degenerative valvular heart disease (n=487443). Intervention: Metabolically unhealthy obese (MUO) and metabolically healthy obese (MHO) phenotypes vs. Metabolically healthy normal weight (MHNO). Primary outcome: Degenerative valvular heart disease (VHD) (HR 1.30, 95% CI 1.24-1.37).

Why the study?

The association between metabolic obesity phenotypes and degenerative valvular heart disease risk and underlying molecular pathways was unclear.

Do metabolic obesity phenotypes increase the risk of degenerative valvular heart disease compared to metabolically healthy normal weight individuals?

Population

487,443 UK Biobank participants

Comparison

Metabolically healthy normal weight vs MHO, MUNO, and MUO phenotypes

Design

Cohort study

Follow-up

Median 13.3 years

Key result

Metabolically unhealthy obesity (HR 1.30; 95% CI 1.24-1.37) and metabolically healthy obesity (HR 1.12; 95% CI 1.07-1.17) were associated with increased risk of degenerative valvular heart disease.

Overview

Obesity phenotypes may elevate degenerative VHD risk; extends observational data but leaves causal effects and prevention strategies open.

Key Points

To evaluate the relationship between distinct metabolic obesity phenotypes and the incidence of degenerative valvular heart disease, while investigating genetic and proteomic mechanisms.
Categorized 487,443 UK Biobank participants into four phenotypes (MHNO, MHO, MUNO, MUO) using BMI and metabolic syndrome criteria over a median 13.3-year follow-up.
Used multivariable-adjusted Cox proportional hazards models to evaluate overall and subtype-specific valvular heart disease risk, integrating polygenic risk scores and plasma proteomics.
Degenerative VHD developed in 12,793 participants (2.6%), with elevated risks in MHO (HR 1.12, 95% CI 1.07-1.17) and MUO (HR 1.30, 95% CI 1.24-1.37) relative to MHNO, but not in MUNO (HR 1.05, 95% CI 0.92-1.19).
Aortic stenosis risk was substantially elevated in MHO (HR 1.42, 95% CI 1.31-1.54) and MUO (HR 1.67, 95% CI 1.32-2.11), peaking in individuals with MUO and high genetic risk (HR 2.91, 95% CI 2.51-3.36; P-interaction=0.938).
Proteomic analysis linked MUO to aortic stenosis-related proteins enriched in immune-inflammation, extracellular matrix remodeling, and MAPK signaling pathways.

Do metabolic obesity phenotypes increase the risk of degenerative valvular heart disease compared to metabolically healthy normal weight individuals?

Population

487,443 UK Biobank participants categorized by BMI and metabolic syndrome criteria, followed for a median of 13.3 years to assess degenerative valvular heart disease risk.

Exposure

Metabolically healthy obese (MHO), metabolically unhealthy normal weight (MUNO), and metabolically unhealthy obese (MUO) phenotypes

Comparator

Metabolically healthy normal weight (MHNO)

Outcome

Risk of degenerative valvular heart disease (VHD) and its subtypes (aortic stenosis, aortic regurgitation, mitral regurgitation)hard clinical

Main Result

Hazard Ratio: 1.3 (95% CI 1.24–1.37)

Obesity, even when metabolically healthy, is associated with an increased risk of degenerative valvular heart disease, particularly aortic stenosis, which is further compounded by metabolic dysfunction.

Yan et al. (2026) conducted a cohort in Degenerative valvular heart disease (n=487,443). Metabolically unhealthy obese (MUO) and metabolically healthy obese (MHO) phenotypes vs. Metabolically healthy normal weight (MHNO) was evaluated on Degenerative valvular heart disease (VHD) (HR 1.30, 95% CI 1.24-1.37). Metabolically unhealthy obesity (HR 1.30; 95% CI 1.24-1.37) and metabolically healthy obesity (HR 1.12; 95% CI 1.07-1.17) were associated with increased risk of degenerative valvular heart disease.
