Heart blockage may be a physiological phenomenon triggered by emotional fluctuations, which does not require special examination, or it may be due to coronary atherosclerotic heart disease, angina pectoris, etc., which requires blood tests and electrocardiograms. 1. Physiological phenomenon: Usually, if the patients often have bad emotions such as anxiety and tension, and their emotions fluctuate a lot, they may have the symptom of heart blockage, which belongs to the normal physiological phenomenon, and no special examination is needed. 2. Coronary atherosclerotic heart disease: this disease is mainly due to the accumulation of plaque in the coronary artery wall, patients need to under the guidance of the doctor to carry out blood tests, load test, echocardiography, electrocardiography, radionuclide examination, coronary CT angiography and coronary angiography and other tests, so as to make a clear diagnosis. 3. Angina pectoris: usually due to the reduction of myocardial blood flow, patients should follow the doctor’s instructions to carry out electrocardiogram, electrocardiogram load test, electrocardiogram continuous dynamic detection, echocardiography and other tests, and also need to carry out blood pressure index examination, nuclear myocardial imaging and load test, chest X-ray, coronary artery enhancement CT, coronary artery angiography, intravascular ultrasonography and other tests, so as to carry out the diagnosis. It is recommended that patients with symptoms of heart blockage should first rule out physiologic factors and, if necessary, undergo the above tests as prescribed by the doctor.
