What is the role of computed tomographic coronary angiography in diabetic patients?

ABSTRACT

UNLABELLED All diabetes specialists are aware of the frequency and severity of coronary disease in diabetics. Non-invasive diagnostic tests perform well, but they could be better. AIM: To assess the role of computed tomographic coronary angiography in diabetics. New cardiac imaging techniques such as CT coronary angiography are promising tools for the selection of patients for conventional X-ray coronary angiography, which remains the key for diagnosis and angioplasty. The limitations of CT coronary angiography, even using the most advanced machines with a 64-slice capacity, are its resolution, the need for an iodine contrast agent and the cumulative radiation from repeated examinations. CONCLUSION: CT coronary angiography appears to have great potential for patients at risk where non-invasive tests cannot absolutely exclude coronary disease and for the follow-up of coronary bypass surgery.
