Acute coronary syndromes are a group of clinical syndromes based on the rupture or invasion of atherosclerotic plaques in the coronary arteries, secondary to complete or incomplete occlusive thrombosis as the pathological basis. In fact many middle-aged and elderly or obese people almost always have atherosclerotic plaques in their coronary arteries. These plaques resemble waxy lipids coated on the vessel walls, making the arteries less elastic and the lumen narrower. When these waxy deposits accumulate piece by piece, they are called atherosclerotic plaques. These plaques grow flush with the intima of blood vessels in the early stage, and if they are not given enough attention, the plaques will slowly protrude into the walls of the vessels, causing different degrees of narrowing of the inner diameter of the arteries; then if they rupture under the influence of cold stimulation, excitement and other reasons, they will “erupt” like a volcano, and the broken plaques will trigger the formation of thrombus, leading to Then, if it ruptures under the influence of cold stimulation or excitement, it will “erupt” like a volcano, and the broken plaque will trigger the formation of thrombus and cause acute coronary syndrome.
