When atherosclerosis occurs with the sudden rupture of plaque in the vessel wall and the formation of a blood clot, the patient’s life can be at risk. Atherosclerosis, also known clinically as atherosclerosis, is the main cause of direct threat to patients’ lives due to the rupture of the plaque formed in the vessel wall and then silted up, or attached to the surface of the vessel wall or in the lumen of the vessel, and the plaque fragments will travel around the body with the blood flow and may occur in various parts of the body with different severity of thrombosis. Once the thrombosis occurs, symptoms such as angina pectoris, coronary heart disease, stroke, myocardial infarction, and when it occurs in the brain, severe cerebral thrombosis may occur. When the thrombus develops seriously it will block the blood vessels, causing symptoms of ischemia in the blood vessels away from the blockage, and its tissues, affecting the normal function of the body, damaging organs and tissues, and threatening the life of the patient.
