Heart Disease Risk & Heart Age

Estimate your 10-year heart disease risk and the age of your heart from a routine blood test. Based on the Copenhagen Male Study (Jeppesen et al. 1998).

Copenhagen Male Study: 2,906 men aged 53–74, 8-year follow-up. 10-year risk normalized via constant hazard model. Age adjustment uses the ACC/AHA Pooled Cohort Equations baseline curve. Heart age = the age at which baseline population risk matches your lipid-adjusted risk. For illustration only, not clinical guidance.
