Study Population
Our study was a single center consecutive trial considering all 753 T2DM patients referred for the first time to the outpatient diabetes clinic at Odense University Hospital, Denmark, from January 1, 2006 to December 21, 2007. Patients were referred by their General Practitioner for one of two reasons: (1) diabetes education at the local four-day diabetes school or (2) glycemic regulation of dysregulated diabetes. No T2DM patient was referred because of symptoms or suspicion of CVD. Inclusion

Characteristics of the T2DM and reference groups are presented in Table 1.
Discussion
Studies using MPS have found a generally high prevalence of myocardial ischemia among asymptomatic patients with T2DM,8, 9, 10, 11, 12, 13, 14 albeit with prevalences varying from 17% to 59%. In this study, we observed a prevalence of myocardial ischemia on MPS that was three times higher in the T2DM group compared with the age-matched nondiabetic reference group (P = 0.007). Even in the asymptomatic T2DM patients (n = 236), the prevalence of myocardial ischemia was as high as 26% (95% CI:
Conclusion
In a consecutive series of T2DM patients, with less than 5 years’ average diabetes duration and without known or suspected CVD, referred to a diabetes clinic for the first time, signs of CVD in one vascular territory carried a significantly increased risk of CVD in other territories as well. The relations between CVD manifestations were, however, not strong enough to allow us to examine only one single vascular territory and then identify all cases of CVD. Therefore, if screening for CVD in
