LDL cholesterol is often referred to as "bad" cholesterol because high levels can lead to plaque buildup in the arteries, increasing the risk of heart disease, stroke, and peripheral artery disease. This test measures the amount of LDL in your blood and helps assess your cardiovascular risk. Monitoring LDL cholesterol levels is important for individuals with risk factors such as obesity, high blood pressure, or a family history of heart disease. It also plays a key role in managing treatment plans, including lifestyle changes and medications aimed at reducing cholesterol levels. Maintaining healthy LDL levels is crucial for heart health and overall well-being.
