Using mean data from the validation study , the trend and directionality in risk was similar in the Roux-en-Y group .
In conclusion , bariatric surgery predicts long-term decreases in CV risk in obese patients
Obese patients have an increased prevalence of  cardiovascular ( CV ) risk factors , which improve with bariatric surgery , but whether bariatric surgery reduces long-term CV events remains ill defined .
Are the Framingham and PROCAM coronary heart disease risk functions applicable to different European populations? The PRIME Study.
AIMS To assess whether the Framingham and PROCAM risk functions were applicable to men in Belfast and France . METHODS AND RESULTS We performed an external validation study within the PRIME ( Prospect i ve Epidemiological Study of Myocardial Infa rct ion ) cohort study . It comprised men recruited in Belfast ( 2399 ) and France ( 7359 ) who were aged 50 to 59 years , free of CHD at baseline ( 1991 to 1993 ) and followed over 5 years for CHD events ( coronary death , myocardial infa rct ion , angina pectoris ) . We compared the relative risks of CHD associated with the classic risk factors in PRIME with those in Framingham and PROCAM cohorts . We then compared the number of predicted and observed 5-year CHD events ( calibration ) . Finally , we estimated the ability of the risk functions to separate high risk from low risk subjects ( discrimination ) . The relative risk of CHD calculated for the various factors in the PRIME population were not statistically different from those published in the Framingham and PROCAM risk functions . The number of CHD events predicted by these risk functions however clearly overestimated those observed in Belfast and France . The two risk functions had a similar ability to separate high risk from low risk subjects in Belfast and France ( c-statistic range : 0.61 - 0.68 ) . CONCLUSION The Framingham and PROCAM risk functions should not be used to estimate the absolute CHD risk of middle-aged men in Belfast and France without any CHD history because of a clear overestimation . Specific population risk functions are needed
