Patients with coronary artery disease do not have high blood lipids and need to continue taking lipid-lowering medications. Coronary heart disease is a general term for atherosclerotic heart disease of the coronary arteries, which can cause atherosclerosis and lipids have a direct relationship. Clinically, if the blood lipids and lipid components are particularly high, the lipids will cause serious damage to the blood vessel walls, leading to vascular sclerosis, which will cause a series of problems, the most common of which are cardiovascular and cerebrovascular diseases, with coronary heart disease bearing the brunt. Therefore, although patients with coronary artery disease do not have high blood lipids, they still need lipid-lowering treatment to prevent heart attacks or unstable angina conditions. Therefore, patients with coronary heart disease need to continue to take long-term, regular lipid-lowering drugs. If the patient’s blood lipids are low or if the lipid-lowering medication is causing damage or adverse reactions in the body, the medication should be stopped intermittently after the doctor’s diagnosis. In general, patients should continue to take lipid-lowering drugs on a long-term and regular basis.
