Study protocol. A total of 461 consecutive patients with diabetes mellitus were prospectively studied between July 2011 and August 2017. All patients were asymptomatic and self-sufficient in daily life and underwent the ERG test. Coronary angiography was performed if the stress test was positive, or if the patients did not achieve 90% of the target heart rate. Non-SMI was diagnosed without coronary angiography if the ERG was negative. Thirty-eight patients underwent coronary angiography despite a negative exercise test. None of the patients had a significant coronary lesion. ERG ergometer exercise, SMI silent myocardial ischaemia.
