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.
