Low-density lipids, also known as low-density lipoprotein cholesterol, data indicators reach 4.1mmol / L is more than the normal range of values, is important, such as can not be given effective treatment, it is easy to cause atherosclerosis, which in turn causes cerebral thrombosis, heart attack and other diseases. The normal range of LDL cholesterol is from 2.07 to 3.37mmol/L, and reaching 4.1mmol/L means that there is a significant increase, which can easily cause atherosclerosis, which is the pathological basis of cardiovascular and cerebrovascular diseases. When atherosclerosis continues to develop, the blood vessels in the arteries will become narrower and narrower, which will have a serious impact on the blood supply, thus causing ischemia such as Brain ischemia, myocardial ischemia and so on. If LDL cholesterol is not controlled, atherosclerotic plaques will continue to form, and these plaques are not stable, when rupture occurs, it will cause platelet aggregation, and ultimately lead to the formation of arterial thrombosis, which will lead to myocardial infarction, cerebral infarction and other diseases. It is recommended that the patient actively cooperate with the doctor for treatment, can follow the doctor’s instructions to take drugs to inhibit platelet aggregation, such as aspirin, etc., but also to take statin drugs to reduce LDL cholesterol, such as atorvastatin, resuvastatin, etc., such as any obvious discomfort, it is necessary to go to the hospital in a timely manner in order to avoid the danger of medical attention. It is recommended to standardize the treatment under the guidance of the doctor and take the medication as prescribed.
