Hello and thank you for using HCM. I carefully read your question and I totally understand your concern. As you are a person diagnosed with ischemic heart disease,meaning having problems with coronary arteries that supply the heart, we allays suspect heart problems when a chest pain appears. You haven t mention the result of the last angiography. I should inform you that there is a slow risk for your stents to be occluded. This risk to have stenosis or blockage in the stents that you have is bigger in the first 6 months. So,if you tell that you do have chest pain it is important to exclude a stent stenosis. Or you might have stenosis in arteryes that should be treated just by medications. But only coronaro-graphy could tell this. There is not a limitation for angyogram number if the doctor has strong suspects that it is something wrong. To decide if you should do coronaro-graphy again or not we should do a balance. If i was your treating doctor i will judge your pain if it is typical or not, but you explain it as a typical one and if it is possible a stress test to see the electrocardiogram evolution. So, it is important to know the full result of your last angiogram and than decide what to do. Hope I was helpful. Wish you good health. Best regards.
