High lipoprotein b may be associated with heart attack, cerebral infarction, coronary heart disease and other diseases, the exact cause of which needs to be evaluated by a doctor. Lipoprotein b transports cholesterol synthesized by the liver to all parts of the body. Its elevation can affect the metabolism of lipids in the body, resulting in a sharp increase of lipids in the blood vessels, which can lead to the formation of atherosclerosis; therefore, lipoprotein b is often used as a criterion for the assessment of atherosclerosis. The elevation of lipoprotein b is also related to some external factors in life, such as a long-term fondness for greasy and fried foods, which contain a high content of fat that enters the body and causes the blood to thicken, which has a great impact on the health of blood vessels. If the blood sampling result has elevated lipoprotein b, you need to go to the hospital and be evaluated by the doctor and formulate a lipid-lowering program.
