Anterior descending stenosis of 85% requires stenting. Anterior descending branch stenosis of 85% is a severe stenosis, which can be diagnosed as coronary artery disease; it is necessary to do percutaneous coronary intervention urgently to place a stent to open the blocked blood vessel, to restore the blood perfusion of the myocardium in order to save the dying myocardium, to prevent infarction from enlarging or to reduce the scope of ischemia of the myocardium. Coronary artery disease patients blood flow reconstruction recommendation table shows that the anterior descending branch of the proximal segment diameter stenosis greater than 70% recommended the use of percutaneous coronary intervention (PCI). At present, most of our country choose transradial artery pathway, which has fewer vascular-related complications and less pain for patients. After PCI, long-term medications such as Rosuvastatin and aspirin are required. Exercise, smoking cessation, and reduction of cholesterol intake are also required. Patients with chest pain that cannot be relieved with rest and nitroglycerin, chest tightness or a sense of dying should go to the hospital in time. If coronary angiography shows anterior descending stenosis of >70%, percutaneous coronary intervention is often recommended, which usually requires a doctor to determine the treatment plan according to the specific condition and follow the doctor’s instructions.
