Myocardial infarction is a relatively common severe heart disease in clinical practice, which can lead to serious complications and even death if effective emergency treatment is not administered. The main cause of myocardial infarction is due to long-term dyslipidemia. Elevated blood lipids cause arteriosclerosis and coronary artery hardening, thickening of the intima, and plaque formation. High lipids slow down blood flow, making it very easy for blood clots to form. Detached plaques and the formation of blood clots obstruct the blood vessels supplying the heart muscle, causing the heart muscle to lose its blood supply and undergo necrosis.
