Hello. Thank you for your question and welcome to HCM. I carefully read your query. As I am let to understand, coronary angiogram was performed. Well, there are different strategies on treating a narrowed or totally blocked coronary artery. It would be really helpful to see the full report and the film. However, I am going to try to address your issue. First, there is angioplasty and stenting of the artery. If the time from onset of a severe, different from others, episode of chest pain to angioplasty is less than six hours, then the benefits on the heart muscle is the highest. I am, of course, referring to a totally closed coronary artery which caused an acute myocardial infarction. If there is a significant blockage to the main artery, and I am assuming that this is the left main coronary artery or the very beginning of the left anterior descendent artery, then the strategy of coronary artery bypass grafting (CABG) provides more benefit in aspects of lifespan and symptom ameliorating. If this is a blockage in the proximal or midden portion of the LAD artery, then angioplasty and stent placement would be the appropriate strategy, with safety and effectiveness. Drug therapy is not an option to opening blockages in coronary arteries, since they, at best, only can stop the progression of the coronary artery disease. As I one mentioned above, if I would see the angiography film, I would be more specific and precise with my recommendations. I hope this helps. Take care. Best regards, Dr. Meriton
