Once palpitations, ischemia and hypoxia occur, patients can use chest tightness, dyspnea, shortness of breath, palpitations, panic, and even dizziness and angina, so once these symptoms occur, they should go to the hospital for examination in time. In terms of examination items, there are electrocardiogram, cardiac ultrasound, coronary CT, coronary angiography and myocardial imaging of nuclear, through which the myocardial ischemia and hypoxia can be clarified The degree of myocardial ischemia and hypoxia, as well as the presence of myocardial infarction, can be determined through these tests. In addition, based on the results of these tests, individualized treatment plans can be tailored, such as conservative medication, coronary stenting, and surgical bypass, all of which can improve myocardial ischemia and hypoxia. Long-term coronary dilation and anticoagulation medications are also required after treatment, which is the only way to maximize the body’s recovery.
