Hello. Thank you for your question and welcome to HCM. I understand your concern. EKG can be suggestive for a remote or a recent myocardial ınfarction, but it is the echocardiogram that can confirm this with higher probability, by assesing the left ventricle wall motion. If I were your doctor, I would have strongly advısed a coronary angıogram. Even if this is cardiac ischemıa and even if it is a remote infarction, it is reasonable to search for other problems within the coronary arteries. If the thing that is scaring you is the procedure itself, I would suggest you no to be scared. There is no such procedure in medicine that is carrıed out with 0 risk. You will be informed in details about the procedure ın your informed consent. You will feel a little pinch which would be the local anaesthesia, and then you will not feel a thing. My opinion remains that there is a strong indication for coronary angiogram in these cases, to depict any problems should they be present and treat them, should the treatment be needed. In the end, recommendations are doctors , the body is yours, so it is your decision. I hope I was helpful. Good luck. Kind regards, Dr. Meriton
