Electrocardiogram suggests T-wave abnormality, lateral wall myocardial ischemia, consider coronary artery disease, according to the results of coronary angiography to be oral anti-myocardial ischemia drugs, coronary stenting and other interventions or coronary artery bypass grafting and other treatments. 1. In general, if the coronary angiography result suggests that the coronary stenosis is mild, aspirin can be given as antiplatelet aggregation, Rosuvastatin can regulate lipid and stabilize the plaque, and isosorbide mononitrate can be given to expand the coronary artery and other anti-myocardial ischemia treatments. 2. In general, if the coronary angiography result suggests that a single simple coronary stenosis is serious and the clinical symptoms are obvious, coronary stent implantation or interventional therapy such as intracoronary balloon dilatation can be given. After the operation, the above anti-myocardial ischemic drug treatment should be continued. 3. If coronary angiography indicates severe or diffuse lesions in multiple coronary arteries, coronary artery bypass grafting can be given as surgical treatment, and the above anti-myocardial ischemic drugs should be continued after the operation. When the electrocardiogram suggests abnormal T-wave lateral wall myocardial ischemia, it is recommended to go to the hospital for timely consultation and further treatment under the guidance of the doctor.
