Left main blockage can generally choose rapid thrombolysis or choose coronary stenting for interventional therapy. Left main myocardial blockage is a more serious disease, you should go to the regular hospital for examination in time, to find out the specific degree of blockage, if in line with the situation of rapid thrombolysis and there is no contraindication to thrombolysis, such as bleeding tendency or the existence of aneurysms, etc., you can choose rapid thrombolysis for treatment first. If possible, coronary angiography and stenting can also be chosen for interventional therapy. The doctor will use a guide wire from the radial artery or femoral artery to reach the blockage area, and then place a stent to restore the blood supply to the lumen after the blood vessel has been cleared. If a left main blockage occurs, you should go to the hospital immediately and choose the appropriate treatment under the doctor’s guidance to avoid delaying your condition.
