Utility of screening for silent myocardial ischaemia in diabetes with an annual electrocardiogram
Authors' conclusion
A low positive yield of routine annual ECG in our study does not support its use as a screening tool for asymptomatic CAD in diabetes. Our findings support advice to perform an ECG at diagnosis of diabetes and to repeat only if a person develops relevant symptoms.
