A commonly measured health marker to assess cardiovascular risk is cholesterol levels, specifically total cholesterol, LDL (low-density lipoprotein), and HDL (high-density lipoprotein) levels. Elevated LDL cholesterol is associated with a higher risk of heart disease, while higher levels of HDL can be protective. Regular screening can help individuals identify their risk and make lifestyle changes based on their cholesterol levels. Monitoring and maintaining healthy cholesterol levels through diet, exercise, and, when necessary, medication is crucial for overall cardiovascular health.
