With the recent technological developments, computed tomography is becoming more important in the diagnosis of cardiovascular diseases. However, potential complications of the radiation dose used during the test have led debates. In the current situation, the data about undesirable effects of radiation dose used in cardiac computed tomography is not clear. In this paper, we reviewed the data about computed tomography and the risk of radiation. In order to reduce the risk of radiation due to computed tomography, the test should be performed with proper indication and in suitable patients. Besides, recently developed radiation dose reduction technologies and patient specific protocols have significantly reduced the radiation exposure. The clinicians should be well informed about the radiation reduction techniques and aware of the technical capabilities in their hospital. [ABSTRACT FROM AUTHOR]

Major cardiovascular events cause about 80% of the total mortality in diabetic patients. It has been shown that diabetic patients have hyperactive platelets. It may be expected that aspirin, through its antiplatelet action, could change the risk for vascular events in people with diabetes. However, some data suggest that aspirin may be less effective than expected in preventing cardiovascular events in patients with diabetes. In this paper, we review the aspirin use in diabetics with respect to cardiovascular endpoints. [ABSTRACT FROM AUTHOR]
