安支架的当天，是要做angiogram还是多排螺旋CT？

Thanks for your reply. Could you explain what the stress test is? Could you give me some links related to coronary artery disease. I check the website americanheart, don't think it's useful.

My dad don't have angina, his heart rate is around 50/min. After taking some medicine, now it is 60/min. no other symptom he feels obviously.

Thanks again
