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 .
The UKPDS risk engine: a model for the risk of coronary heart disease in Type II diabetes (UKPDS 56).
A definitive model for predicting absolute risk of coronary heart disease ( CHD ) in male and female people with Type II diabetes is not yet available . This paper provides an equation for estimating the risk of new CHD events in people with Type II diabetes , based on data from 4540 U.K. Prospect i ve Diabetes Study male and female patients . Unlike previously published risk equations , the model is diabetes-specific and incorporates  glycaemia , systolic blood pressure and lipid levels  as risk factors , in addition to age , sex , ethnic group , smoking status and time since diagnosis of diabetes . All variables included in the final model were statistically significant ( P<0.001 , except smoking for which P=0.0013 ) in likelihood ratio testing . This model provides the estimates of CHD risk required by current guidelines for the primary prevention of CHD in Type II diabetes
Using mean data from the validation study , the trend and directionality in risk was similar in the Roux-en-Y group .
