Note: Risk calculated from Framingham Heart Study Risk Functions as described in Wilson 1998 and D’Agostino 2001.

Risks are estimated only for persons not previously diagnosed with a heart attack.

The sample size for 1988–1994 is 1862 and for 2005–2008 is 1563.

Age groups are collapsed to create stable estimates for race/ethnicity.

^*Change in risk across time periods is statistically significant at the P ≤ .05 level.
