Anterior wall myocardial infarction is indicated by a large myocardial infarction if coronary CT or cardiac angiography suggests 90% blockage of the anterior descending branches. The coronary arteries are the blood vessels responsible for delivering oxygen to the heart muscle and surround the entire heart; the two main branches are the left coronary artery and the right coronary artery. The left coronary artery carries blood to the left side of the heart and is divided into the left anterior descending branch and the left circumflex branch. The anterior descending branch is responsible for supplying most of the myocardium at the front of the heart, so if the anterior descending branch is 90% occluded, then the heart is at a higher risk of various cardiovascular adverse events, and the risk of sudden cardiac death is high, and it is recommended to implant a cardiac stent. Myocardial infarction is a cardiac emergency and its main manifestation is the symptoms of chest tightness and chest pain. If the diagnosis of myocardial infarction is clear, the patient should go to the hospital immediately and under the guidance of the clinician, the patient should undergo revascularization therapy as soon as possible.
