Key result

Low cardiovascular health and high metabolic vulnerability linked to ~2.8-fold higher MACE risk.

HR 2.84
95% CI 2.60, 3.12
n=239,135

Why the study?

The metabolic vulnerability index (MVX) captures metabolic-inflammatory vulnerability, but its joint relevance with Life's Essential 8 (LE8) for major adverse cardiovascular events (MACE) is unclear.

Does combined assessment of the Metabolic Vulnerability Index (MVX) and Life's Essential 8 (LE8) predict the risk of major adverse cardiovascular events in adults free of baseline MACE?

Key Points

To assess the independent and joint associations of the NMR-derived metabolic vulnerability index and Life's Essential 8 cardiovascular health scores with the risk of incident major adverse cardiovascular events.
Prospective cohort analysis of 239,135 UK Biobank participants free of baseline cardiovascular disease followed for a median of 13.6 years.
Metabolic vulnerability index (MVX) was quantified using six NMR-derived circulating biomarkers, and cardiovascular health (CVH) was categorized as low (<60), moderate (60–79), or high (≥80) using Life's Essential 8 (LE8).
Multivariable Cox proportional hazards models, additive interaction analyses, and counterfactual models evaluated incident major adverse cardiovascular events (MACE) and individual cardiovascular endpoints.
Over 13.6 years of follow-up, 17,146 incident MACE occurred; higher MVX was associated with increased MACE risk (HR = 1.08, 95% CI: 1.07, 1.10), whereas high versus low CVH was associated with reduced risk (HR = 0.44, 95% CI: 0.41, 0.47).
Participants with low CVH and the highest MVX quartile exhibited the greatest MACE risk compared to those with high CVH and the lowest MVX quartile (HR = 2.84, 95% CI: 2.60, 3.12), with significant additive interaction observed for MACE and myocardial infarction.
Counterfactual modeling indicated that achieving high CVH (LE8 ≥80) could potentially prevent between 27.02% (95% CI: 23.19%, 30.75%) and 46.18% (95% CI: 43.34%, 48.98%) of MACE across metabolic vulnerability quartiles.

O

Outcome

Main Result

Hazard Ratio: 2.84 (95% CI 2.6–3.12)

Combined assessment of the metabolic vulnerability index and Life's Essential 8 improves cardiovascular risk stratification, demonstrating that optimal cardiovascular health can substantially attenuate the high MACE risk associated with intrinsic metabolic vulnerability.

Limitations

Predominantly composed of White participants
Subject to a healthy volunteer effect
Relatively small number of non-White participants limited precision
Differential misclassification related to routinely collected ICD-based outcome definitions

Implication

MVX may enhance LE8-based MACE risk stratification; leaves open whether intervening on metabolic-inflammatory pathways alters outcomes.

Abstract

The metabolic vulnerability index (MVX) captures metabolic-inflammatory vulnerability, but its joint relevance with Life’s Essential 8 (LE8) for major adverse cardiovascular events (MACE) is unclear. We analyzed 239,135 UK Biobank participants free of baseline MACE. MVX was calculated from six NMR-based biomarkers. LE8 scores were classified as low (<60), moderate (60–79), or high (≥80) cardiovascular health (CVH). Cox models evaluated associations of MVX and LE8 with incident MACE; joint-effect, interaction, counterfactual, and mediation analyses were conducted. Over a median 13.6 years, 17,146 MACE occurred. Higher MVX was associated with higher MACE risk (HR = 1.08, 95% CI: 1.07, 1.10), whereas high CVH was associated with lower risk compared to low CVH (HR = 0.44, 95% CI: 0.41, 0.47). Participants with low CVH and MVX Q4 had the highest risk (HR = 2.84, 95% CI: 2.60, 3.12). Additive interaction was evident for MACE and myocardial infarction. Counterfactual and mediation analyses suggested that better CVH could prevent a substantial proportion of events, partly through lower metabolic vulnerability. Combined MVX and LE8 assessment may improve cardiovascular risk stratification and support targeted prevention.
