Atherosclerotic thrombosis is because when atherosclerosis leads to narrowing of the lumen of the arteries, the patient’s blood flow in this area will change and the vortex will increase, so the blood flow will be relatively slow, and this will easily lead to the formation of thrombus, coupled with atherosclerosis, the endothelial cells of the blood vessels are not smooth and prone to rupture. In order to repair these atherosclerosis by lesions in the intima, so platelets will gather on it, it will be easy to form thrombus on it, atherosclerosis, the formation of thrombus, the patient will have an acute ischemic situation, such as will be on the basis of atherosclerosis, the formation of a complete blockage of the coronary arteries, causing myocardial infarction.
