Coronary blood vessels completely blocked, timely intervention and thrombolytic therapy, can be unblocked. Complete blockage of coronary blood vessels indicates that the patient’s coronary heart disease is in a more serious state, and the patient will usually experience symptoms such as chest tightness, shortness of breath and chest pain. Patients with such symptoms can be examined by coronary angiography, and if the lesion is in a single vessel, it can be treated by stent implantation. If the lesion in three branches of the coronary artery is more serious and diffuse, it can be treated by coronary artery bypass grafting. Coronary stenting can also be staged if bypass surgery is not allowed. If the occlusion is acute and there is no contraindication to thrombolysis within the first 3 hours of the onset of the disease, it can be treated by thrombolysis. Patients should also adjust their diet during the treatment period, usually pay attention to low salt and low fat in the diet, do not eat too greasy food. You can eat some fresh vegetables and moderate amount of fruits. If there is any discomfort, it is recommended to go to the hospital for treatment in time.
