Exercise Testing to Screen for Unknown Coronary Artery Disease in Diabetic Patients: Does it Contribute to a Risk Reduction in Very High Risk Patients? (DADDY-D)

November 19, 2012 updated by: TURRINI FABRIZIO

Screening Asymptomatic Patients With Diabetes for Unknown Coronary Artery Disease: an Open-label Randomized Study Comparing Exercise Testing Strategy With Management Based on Pharmacological/Behavioral Treatment of Traditional Risk Factors

In the present study a cohort of diabetic patients without any symptoms and without known coronary artery disease (CAD) will be screened at the investigators' diabetes outpatients services. Those with intermediate or high risk will be asked to participate and enrolled. They will be seen and followed by the cardiologists in order to provide the best adherence to medical therapy. By mean of a randomization process, a group of patients will undergo an exercise electrocardiography (ECG) testing while the other group will continue to be regularly seen at the investigators' cardiology service. Those patients with a positive exercise ECG test will be study by coronary angiography and treated according to the severity of coronary lesions by percutaneous stenting or surgery. Both groups of patients will be seen every six-eight months for the next three years.
