TLDR
The Detection of Ischemia in Asymptomatic Diabetics (DIAD) study as discussed by the authors was a randomized controlled trial in which 1123 patients with type 2 diabetes and no symptoms of coronary artery disease were randomly assigned to be screened with adenosine-stress radionuclide myocardial perfusion imaging (MPI) or not.Abstract:
CONTEXT
Coronary artery disease (CAD) is the major cause of mortality and morbidity in patients with type 2 diabetes. But the utility of screening patients with type 2 diabetes for asymptomatic CAD is controversial.
OBJECTIVE
To assess whether routine screening for CAD identifies patients with type 2 diabetes as being at high cardiac risk and whether it affects their cardiac outcomes.
DESIGN, SETTING, AND PATIENTS
The Detection of Ischemia in Asymptomatic Diabetics (DIAD) study is a randomized controlled trial in which 1123 participants with type 2 diabetes and no symptoms of CAD were randomly assigned to be screened with adenosine-stress radionuclide myocardial perfusion imaging (MPI) or not to be screened. Participants were recruited from diabetes clinics and practices and prospectively followed up from August 2000 to September 2007.
MAIN OUTCOME MEASURE
Cardiac death or nonfatal myocardial infarction (MI).
RESULTS
The cumulative cardiac event rate was 2.9% over a mean (SD) follow-up of 4.8 (0.9) years for an average of 0.6% per year. Seven nonfatal MIs and 8 cardiac deaths (2.7%) occurred among the screened group and 10 nonfatal MIs and 7 cardiac deaths (3.0%) among the not-screened group (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.44-1.88; P = .73). Of those in the screened group, 409 participants with normal results and 50 with small MPI defects had lower event rates than the 33 with moderate or large MPI defects; 0.4% per year vs 2.4% per year (HR, 6.3; 95% CI, 1.9-20.1; P = .001). Nevertheless, the positive predictive value of having moderate or large MPI defects was only 12%. The overall rate of coronary revascularization was low in both groups: 31 (5.5%) in the screened group and 44 (7.8%) in the unscreened group (HR, 0.71; 95% CI, 0.45-1.1; P = .14). During the course of study there was a significant and equivalent increase in primary medical prevention in both groups.
CONCLUSION
In this contemporary study population of patients with diabetes, the cardiac event rates were low and were not significantly reduced by MPI screening for myocardial ischemia over 4.8 years.

Screening for asymptomatic coronary artery disease in patients with diabetes mellitus: A systematic review and meta-analysis of randomized trials.
TL;DR: The present analysis shows no evidence for a benefit of screening diabetic patients for the presence of asymptomatic CAD, and the proportion of patients who undergo myocardial revascularization as a consequence of screening was low.

TL;DR: Findings support diabetes as a CAD equivalent and suggest that MPI provides additional prognostic information in such patients with non-diabetic patients with CAD after stratification by MPI results.

TL;DR: Findings indicate that the "diabetes epidemic" will continue even if levels of obesity remain constant, and given the increasing prevalence of obesity, it is likely that these figures provide an underestimate of future diabetes prevalence.

TL;DR: The use of intensive therapy to target normal glycated hemoglobin levels for 3.5 years increased mortality and did not significantly reduce major cardiovascular events and identify a previously unrecognized harm of intensive glucose lowering in high-risk patients with type 2 diabetes.

TL;DR: The most prevalent form of diabetes mellitus is type 2 diabetes as discussed by the authors, which typically makes its appearance later in life and is associated with other cardiovascular risk factors: dyslipidemia, hypertension, and prothrombotic factors.
