Relatively speaking, for patients with poor microcirculation, such as those with syndrome X, the application of drugs such as prostilbestrol can improve the microcirculation relatively well. In addition, oral medications, such as nicorandil, can also improve the patient’s precordial discomfort. However, it is usually not possible to completely open or improve the disease, but it is possible to take related drugs to prevent the progression of the disease and relieve the patient’s discomfort. If the patient belongs to syndrome X, this type of disease often does not reveal any serious problems in the large blood vessels when coronary CT or coronary angiography is done, but the patient still has discomfort, it is considered to be caused by microcirculation problems. Patients can further perform an electrocardiogram exercise bicycle test, and if it is positive, it is highly considered to be syndrome X. It is recommended that such patients can also take oral aspirin to help improve the discomfort better.
