Hi. Thank you for asking on HCM. I understand your concern. I would recommend the stent implantation as the best choice, in this picture. He, apparently, has had poor controlled diabetes for some time now, and this is diabetes that has produced significant peripheral damage. Coronary artery bypass grafting is an available option, but accompanied with a great procedural risk. He can also try with medications, but this approach is not a solution for coronary artery disease. It merely relieves some of the symptoms, with no benefit on life-span, and with having the coronary disease not progress further, at best. Therefore, my opinion is that the best option is percutaneous coronary intervention. For how many stents should be placed, it is best that you rely on the invasive cardiologist s decision, who is carrying out the procedure. I hope I was helpful with my answer. Best regards.
