T-wave abnormalities are classified into specific and non-specific abnormal changes. Generally, non-specific abnormal changes are patients with no clear risk factors for coronary heart disease, mostly seen in young women or patients with chronic mental stress, in this case, most of the T wave abnormalities do not need to be dealt with, and only need regular follow-up observation. In the case of older patients, or patients with hypertension, hyperlipidemia, hyperuricemia, hyperglycemia, etc., T wave abnormalities should first be identified as coronary artery disease, and if there are T wave abnormalities combined with typical angina symptoms, further cardiac ultrasound and coronary CTA examination should be performed to clarify the severity of coronary artery disease. If there is no clear cause of coronary heart disease, no medication is needed; if there are clear risk factors for coronary heart disease, oral aspirin and other medications are recommended for treatment.
