Patient: In 2009, I felt occasional chest discomfort, and in 12 years, I started to feel chest tightness after exercise such as going upstairs, but I did not feel it after exercise. Is there any risk? Is there a better way to do it?’ Thanks. Doctor: Your imaging data is not very clear, and the above films of these positions do not show well the lesion of the anterior descending branch throughout, which may affect the assessment of the disease. However, from the only films available, your coronary lesion is a multi-branch lesion, and the lesion is diffuse in scope. The right coronary does not show up because of complete blockage, but retrograde visualization is still possible, so the lesion itself may be more suitable for bypass surgery to solve the blood supply problem more completely. It is recommended to provide complete medical history and impact data for consultation. The above advice is for reference only. Patient: First of all, thank you very much for your opinion, the hospital said to do stent, later there is a second chance to do bypass, if now do bypass in the future what problems can not be done again, so we are very conflicted, I want to ask if to do stent, according to these images to see stent surgery is not and risky? Thank you patient: please give me some advice, I am very afraid now, my dad is the most important person to me, I don’t know how to decide, will this stent surgery be risky? My dad is fine now, he won’t have any symptoms if he doesn’t exercise, we don’t want to have a bypass, what are the pros and cons of not having a bypass and choosing to have a stent? Doctor: Of course there are risks with stenting, but it is less than coronary artery bypass surgery, whether it is suitable for stenting or not depends on the degree of anterior descending branch lesion, of course, if it is suitable for stenting then of course it is the most ideal, less trauma, less risk and still have the opportunity to operate in the future, the key is to be suitable, otherwise if the lesion is heavy, it may not solve the problem even after stenting. It is still necessary to have good communication with your local doctor, after all they have the first-hand information. Patient: I’m much more stable, I’ll communicate with the doctor properly, on behalf of the whole family, I’d like to express my heartfelt thanks to you for your patient analysis and reply, you are definitely a good and respected doctor, thank you very much. I hope my father is healthy and safe, and I wish you all the best, doctor. Patient: Hello again, my father had stent surgery 4 months ago, three branches of coronary artery disease, right coronary blockage, anterior descending and gyral branch blockage, the doctor put a stent ‘now always coughing’, please ask what should be done? Doctor: Is there any phlegm in the cough? You should see if there are any problems with the respiratory tract. Some antihypertensive drugs have side effects that cause a dry cough, such as captopril.
