Systemic Inflammation Predicts All-Cause Mortality: A Glasgow Inflammation Outcome Study

This Glasgow Inflammation Outcome Study followed 160,481 patients to determine whether systemic inflammatory markers — specifically CRP, albumin, and neutrophil count — predicted all-cause, cancer, cardiovascular, and cerebrovascular mortality independently.

All three inflammatory markers were independently predictive of mortality. A composite inflammation score combining CRP, albumin, and neutrophil count was a stronger all-cause mortality predictor than any single marker alone. The prognostic gradient across inflammation score categories was steep and consistent across the major cause-of-death categories, confirming that systemic inflammation is not narrowly organ-specific in its mortality contribution.

The clinical relevance for cardiovascular risk assessment is significant. CRP alone — particularly hs-CRP — is already incorporated in several cardiovascular risk algorithms (Reynolds Risk Score, coronary artery calcium reclassification pathways, JUPITER trial entry criteria). This study extends the inflammation-mortality relationship to a broader composite, and its scale provides high statistical confidence.

For practical risk stratification, hs-CRP remains the most accessible and validated inflammatory biomarker. This study supports treating persistently elevated CRP as a meaningful risk signal warranting comprehensive risk assessment and active management of modifiable cardiovascular risk factors.

We rate the evidence strong. A large, well-powered cohort study confirming systemic inflammation as a robust independent predictor of all-cause and cause-specific mortality — supporting inflammation’s role in comprehensive cardiovascular risk assessment.
