Beyond Spirometry
Lung function tests only tell part of the story. COPD is a systemic disease that ages your entire body - and GrimAge captures this.
Systemic Inflammation
COPD causes body-wide inflammation that accelerates aging in the heart, brain, and metabolic systems - not just the lungs.
Smoking Legacy
GrimAge includes DNAm Pack Years - it directly measures the epigenetic signature of smoking damage even after quitting.
Comorbidity Risk
COPD patients have elevated risk of heart disease, diabetes, and cognitive decline - GrimAge predicts these better than FEV1.
Why GrimAge for COPD?
Traditional measures like FEV1 capture lung damage but miss the systemic aging that drives COPD mortality. GrimAge fills this gap.
Superior Mortality Prediction
GrimAge predicts COPD mortality better than spirometry alone
Captures Smoking Damage
DNAm Pack Years component specifically measures smoking's epigenetic legacy
Exacerbation Risk
Higher GrimAge acceleration predicts more frequent COPD exacerbations
Track Interventions
Monitor whether pulmonary rehab and lifestyle changes affect biological age

Frequently Asked Questions
How is GrimAge different from lung function tests?
Spirometry measures airflow limitation in your lungs. GrimAge measures biological aging across your entire body, including the systemic effects of COPD like inflammation and cardiovascular risk. They complement each other - GrimAge adds the "big picture" to spirometry's lung focus.
Can quitting smoking improve my GrimAge?
Smoking cessation stops adding new epigenetic damage, but some changes persist. However, the inflammation and other factors that contribute to GrimAge can improve with cessation, exercise, and proper COPD management. Tracking GrimAge over time shows these improvements.
Does pulmonary rehabilitation affect biological age?
Early research suggests that exercise and pulmonary rehab can improve epigenetic aging markers. This is one of the questions our study aims to answer definitively for COPD patients.
What COPD stages are eligible?
All GOLD stages (I-IV) are eligible. In fact, we're particularly interested in comparing biological age across different disease stages to understand how GrimAge changes with COPD progression.
Will my results be shared with my pulmonologist?
That's your choice. We provide comprehensive reports that you can share with your healthcare team if you wish. Many patients find it valuable to discuss their biological age with their pulmonologist as part of comprehensive COPD management.
