Coronary heart disease, known as coronary atherosclerotic heart disease, is a disease caused by atherosclerosis of the coronary arteries resulting in narrowing or occlusion of the lumen of the arteries, even if the left main stem is not narrowed, treatment is required.
The coronary arteries have three main vessels: the anterior descending branch, the circumflex branch, and the right coronary artery, which branches off from the left main artery. Although the left main trunk is not stenotic, stenosis of the anterior descending branch, the circumflex branch, and the right coronary artery can be life-threatening and require treatment.
The anterior descending branch of the coronary artery is the main blood vessel supplying the anterior wall of the left ventricle, the anterior interventricular wall, and the anterior papillary muscles; the rotary branch of the coronary artery is the main blood vessel supplying the high lateral wall of the left ventricle and the left atrium; and the right coronary artery is the main blood vessel supplying the lower wall of the heart, the posterior septum, and the sinus node.
Coronary artery disease can lead to myocardial infarction, which can be life-threatening, so if you are diagnosed with coronary artery disease, please follow your doctor’s instructions for treatment.
