I went through coronary angiography two years ago. It was completely normal, with no blockage. But I have a myocardial bridge. Two days before, I went for a body check-up where my TMT was positive with the exercise of eight minutes and 106 beats per minute heart rate with no pain or breathlessness, but TMT was positive for myocardial ischemia. I have controlled blood pressure and diabetes. But there is no family history of heart disease. Please help. Thanks.
