The therapeutic effect of statins is mainly a hypolipidemic effect, especially for hypercholesterolemia or mixed hyperlipidemia with predominantly cholesterol. In addition, it has the effect of plaque stabilization and anti-atherosclerosis. In clinical practice, patients with coronary heart disease or cerebrovascular disease have atherosclerosis and plaque stenosis, so statins can be used to stabilize the plaque and anti-atherosclerosis effect. Therefore, the clinical application of these drugs is very wide and beneficial. Very few people may experience side effects of statins, such as elevated transaminases in liver function, rhabdomyolysis or muscle pain, so it is important to monitor liver function during this period when taking statins, and if side effects occur, discontinue them in a timely manner, seek medical guidance, and adjust drug therapy when necessary.
