We derived equations for predicting cardiovascular disease (CVD) risks for Thai men and women, separately, over a specific time period using associations between risk factors and CVD events from the Framingham cohort study. The equations were recalibrated against the cumulative risks estimated for Thailand. Equations were developed separately for predicting risks of ischemic heart disease (IHD) and stroke. Recalibration of the Framingham equations reduced the CVD risks predicted for Thai men by 97% and for Thai women by 10%. The correction was largest at younger ages. In older women, recalibration increased the predicted risk. When compared with an existing equation for Thai men our recalibrated Framingham equation produced similar predictions for CVD risks over 8 years. However, the recalibrated Framingham equations are more flexible because they can be used for predicting risks over any time span and for women and men.
