Customer question:

What is LDL cholesterol? Anonymous customer's question

Pharmacist's answer:

LDL cholesterol, which stands for low-density lipoprotein, is a lipoprotein found in the blood plasma and plays a vital role in cholesterol transport throughout the body. LDL cholesterol is often known as "bad" cholesterol because high levels of LDL cholesterol in the blood can increase the risk of cardiovascular disease.

Its role is to transport cholesterol from the liver, where it is produced, to tissues throughout the body, where it is used to build cell membranes, synthesize hormones, and other vital functions. However, too much LDL cholesterol in the blood can cause problems because it can build up on artery walls and form atherosclerotic plaques, which can increase the risk of heart attack, stroke, and other cardiovascular diseases.

LDL cholesterol levels in the blood can be caused by various factors, including genetics, diet, physical activity, weight, smoking, and other risk factors for cardiovascular disease. High levels of LDL cholesterol are one of the main components of metabolic syndrome, which is often accompanied by obesity, high blood pressure, high blood sugar levels, and other metabolic disorders.

Diagnostic tests such as the lipid blood test measure the level of LDL cholesterol in the blood. The Friedewald equation, based on total cholesterol, HDL cholesterol, and triglycerides in the blood, is often used to calculate LDL cholesterol.

LDL cholesterol targets are used as part of a comprehensive CVD risk assessment. The generally accepted target value for LDL cholesterol is less than 100 mg/dL, although a doctor may recommend even lower goals, such as less than 70 mg/dL, for some individuals at increased risk of cardiovascular disease.

Treating high LDL cholesterol levels involves both lifestyle changes and medication. Lifestyle changes such as eating a healthy diet, being physically active, quitting smoking, and losing weight can help lower LDL cholesterol levels. Medications such as statins, fibrates, cholesterol absorption inhibitors, and others may be prescribed to lower LDL cholesterol in people at high risk for cardiovascular disease.

In addition, targeted therapies such as PCSK9 inhibitors can also be used for people with inherited metabolic disorders that cause very high levels of LDL cholesterol despite drug treatment. It is important to note that LDL cholesterol levels are not the only risk factor for cardiovascular disease. It is vital to assess risk based on several factors, including age, gender, smoking, blood pressure, diabetes, family history of heart disease, and other risk factors.
