When you are angry, sympathetic excitement will cause your heart to beat faster, and if you have underlying coronary artery disease, this will lead to a transient blood theft in the narrowed blood vessels of the heart. The presence of transient blood theft will cause the subsequent myocardial cells to be deprived of adequate oxygen and blood supply, which will eventually lead to heart pain. In this case, you should visit the cardiology department of your local hospital and have an electrocardiogram performed, including the resting electrocardiogram and the electrocardiogram when the pain is caused by anger, to determine whether there are any dynamic ST-T changes in the two electrocardiograms. If not, a myocardial enzyme profile should be performed to determine if there is any damage to the cardiomyocytes. A coronary CT is then performed to determine if there is any stenosis in the three coronary arteries on the surface of the heart. If there is stenosis, and if the stenosis is more than 50%-60%, hospitalization for coronary angiography should be performed to determine whether the stenosis requires stent placement to open the vessel.
