Hi. Welcome to our community. Glad to see you are already participating here in the forums. Sorry that you have been diagnosed with a 50 percent blockage of your artery. You are not alone here in this community with this diagnosis -- and many who have had it successfully treated and are doing quite well. Yours is a great question, and a common one. We do have lots of articles on this topic. For basic information about coronary heart disease, you may find this article helpful (https://heart-failure.net/clinical/coronary-artery-disease-basics). For an information about treatment options, you may find this article helpful (https://heart-failure.net/clinical/coronary-artery-disease-basics). That said, I am curious: Has your cardiologist talked to you about your diagnosis at all? Has he/she discussed treatment options for you? Wishing you all the best.
