For patients with lateral myocardial ischemia, if it is caused by coronary atherosclerotic heart disease, it is recommended that the patient can routinely take aspirin and statins, and if the effect is not good when taking the above drugs, you can combine them with isosorbide nitrate or vancomycin and betalactam. If necessary, coronary CT or ECG trolley test can be performed to further clarify the diagnosis and help rule out whether the patient’s current condition is due to syndrome X or poor microcirculation. If it is caused by poor microcirculation, it is recommended that the patient can take aspirin and statins in combination with drugs such as Xigramax, which is relatively more advantageous for improving microcirculation.
