<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 64 diabetic male without any symptoms of heart disease, I had a vascular screening, showing no evidence of plaque blockages, I am awaiting the results of a nuclear stress tests, should I worry? Is there a correlation between carotid blockages and coronary blockages?  <response>: Hello Diabetes is a major risk factor for coronary heart disease as it promotes atherosclerotic changes throughout the body vasculature but again if your control on diabetes is good that risk comes down to minimum. So I would suggest you to maintain a healthy life style and DO NOT INDULGE IN SMOKING if you do. Now answering your question: No there is no obvious relationship among the two but as it is due to atherosclerosis blockage can coexist in both up to some extent. Good Luck
