Hello. Thank you for your question and welcome to HCM. I read your query and I understand your concern. By the brief information you provided, I am assuming these blockages are in delicate parts of coronary arteries. Further, I think the main blockage is in the left main coronary artery (LMCA) or in the ostial (entering) part of the left anterior descendent (LAD) artery. From all data that exist and from our clinic s experience, the stent placement in these portions is a very dangerous procedure, both technically and from a result-oriented point of view. Therapy with drugs will only help you calm your symptoms, while the plaque is still stable. But, this blockage will eventually get bigger and totally block the artery, causing a heart attack which, in this position of the artery, is potentially lethal. Therefore, my recommendation is that you should proceed with the coronary artery bypass grafting (CABG). Of course, the choice is only yours. I hope I was helpful and thorough in my answer. Good luck!
