<s>[INST] Doctor my husband aged 50 years has diabetes for the past 2 years and Hypertension  Took a tread mill test whicChatDoctore positive . refererred for angiogram. Hb(Gly) 6.2, Please enlighten us on the percentage of   blockage he might have ? [/INST] Hello, Regarding your concern, I would explain that the treadmill test cannot show the percentage of coronary artery blockage. It can just indicate the presence of myocardial ischemia during physical exertion. The coronary angiogram is the golden standard test to examine the blood flow in the coronary arteries and detect with high precision the percentage of blockage in each of them. I would be glad to review those test reports for a more professional opinion as soon as you will be able to upload them on this site. Hope I have answered your query. Let me know if I can assist you further. </s>
