Estimates of Age‐Standardized Mean Heart Agea and Mean Excess Heart Age for the US Population Aged 30 to 74 Without CVD, NHANES 2007–2014
| Overall Years (SE) | Without Family History of CVDbYears (SE) | With Family History of CVDbYears (SE) | |
|---|---|---|---|
| Chronological age | 48.0 (0.04) | 48.0 (0.04) | 48.0 (0.10) |
| Heart age | 55.3 (0.18) | 55.0 (0.18) | 57.6c (0.39) |
| Excess heart ageb | 7.3 (0.17) | 7.0 (0.17) | 9.6c (0.38) |
CVD indicates cardiovascular disease; NHANES, National Health and Nutrition Examination Survey; SE, standard error.
a
Age‐standardized by the direct method to the US 2000 census population using the age groups 30 to 39, 40 to 49, 50 to 59, 60 to 69, and 70 to 74 years.
b
Excess heart age is the difference between heart age and chronological age.
c
Difference in age for the population with and without family history of heart disease is significant (P<0.05).
