I'm looking for some advice about my heart health. I had a CT coronary angiogram about three years ago because I was having chest pains and my exercise capacity was low. The results showed no significant stenosis in any artery, but Im wondering if minor blockages might have been overlooked. Also, it mentioned that my circulation is left dominant, and I'm curious if that could be related to my chest pain. Do you think it's necessary to repeat the CT angio even though I'm worried about the radiation exposure?

If your CT coronary angiogram from 3 years ago showed no significant stenosis in any artery, it means that there were no major blockages detected at that time. Minor blocks may not have been mentioned in the report because they were not significant enough to cause concern. The fact that your circulation is left dominant is just a variation in the blood supply to your heart and is not necessarily a cause for chest pain. Based on the information provided, if you are still experiencing chest pains or other concerning symptoms, it may be advisable to consult with a cardiologist to determine if a repeat CT angio or other cardiac tests are necessary. However, the decision to repeat the CT angio should be based on your current symptoms and risk factors, rather than just for routine surveillance. It is important to weigh the potential benefits of the test against the risks of radiation exposure.

My dad had a heart attack recently and the doctor suggested he needs an angiography. I'm really worried and wonder what we should expect from this procedure. Is it risky, or are there any side effects we should be aware of? How soon should he have it done, and is there anything specific we need to prepare for before the angiography?

After a heart attack, angiography is often recommended to assess the extent of blockages in the coronary arteries. This procedure can help determine the best course of treatment. Your father may be prescribed medications such as Aspirin, Clopidogrel, and Atorvastatin to prevent further complications and manage his heart health. The dosage and duration of these medications will be determined by his doctor based on his individual condition.
