As we all know, coronary heart disease is the number one “killer” that endangers human life and health in modern times, so the prevention and treatment of coronary heart disease has become the unshirkable responsibility and obligation of cardiovascular doctors. In my long-term clinical work, I have observed that many patients with coronary heart disease can insist on taking oral medications that can significantly relieve symptoms, such as betalactam, cardiac pain, aspirin and other drugs, but often neglect to take “statin” drugs, for two reasons: First, they do not understand the role of “statin” drugs and think that they do not play a key role. One is that they do not understand the role of “statins” and think that they do not play a key role, and the other is that “statins” are expensive and economically damaging. I think the first reason is the most important, so I am here to clarify this misunderstanding with the help of the Internet, so that “statin” drugs can better serve everyone, to avoid the occurrence of cardiovascular malignant events, to avoid the occurrence of a scene of tragedy. Statins such as simvastatin, atorvastatin, resupristatin, etc. are all in this category. These drugs used to be called lipid-lowering drugs, mainly to lower cholesterol and LDL cholesterol, but also lower triglycerides, but the magnitude is smaller. With the in-depth research on statins, we found that for patients with coronary heart disease, long-term use of statins can help improve the condition of coronary heart disease and reduce the occurrence of coronary heart disease acute events, such as: reducing the occurrence of myocardial infarction For example, they can reduce the occurrence of myocardial infarction, sudden death, and angina pectoris. What is the reason for this? This is because statin drugs: 1) reduce the progression of vascular sclerosis and stenosis by lowering cholesterol and reducing the deposition of cholesterol in the vessel wall; 2) improve the function of vascular endothelial cells and make them secrete substances that protect blood vessels and slow down vascular aging; 3) counteract chronic inflammation of the vessel wall and It can stabilize the plaque of coronary arteries and reduce the chance of rupture, just like reducing the eruption of volcanoes; 4, it can fight against the oxidative stress in the body and reduce the role of free radicals, thus stabilizing the arterial plaque and reducing the occurrence of acute events. All of these “statin” drugs are based on expert consensus from several large-scale international clinical trials, in which as many as tens of thousands of patients participated for as long as 5-6 years. Therefore, long-term use of statins is not the opinion of one doctor or one expert, but the result of multiple clinical trials. Some patients say, “My blood lipids are already normal, do I need to continue taking them? The answer is yes, you must continue unless there are significant side effects. If you stop taking statins, the enzymatic activity of cholesterol synthesis will increase again and cholesterol will slowly rise again, which will continue to damage the walls of your blood vessels and make your disease progress. Some patients say, “I don’t have high blood lipids, even though I have coronary artery disease, so I don’t need to take it? No, not really. Because the cause of coronary heart disease is not only high blood lipids, but also a variety of factors. “Statin drugs not only lower blood lipids, but also have many good effects as mentioned above, so as long as you have coronary heart disease, try to take statin drugs, so as to reduce the risk of cardiovascular events. Other patients have doubts: if I take statins for a long time, there must be side effects, so I might as well not take them. In fact, the side effects of statins are not so terrible and the chance is relatively low, and can be avoided by paying attention to testing when taking the medication. It is recommended that you check your liver function and creatine kinase before taking the medication, and then recheck it half a month to a month after taking the medication, if there is no problem, you can basically take it without worry. After three months and then recheck, if it is very good, basically you can say that you have no major side effects to this drug. If you encounter a new situation, go to the hospital in time to see your doctor for advice and adjust your medication.
