Cholesterol reduction refers to medical and lifestyle interventions aimed at decreasing elevated levels of low-density lipoprotein (LDL) cholesterol and total cholesterol in the blood. High cholesterol is a significant risk factor for cardiovascular diseases, including atherosclerosis, heart attack, and stroke. Strategies involve dietary modifications, increased physical activity, and pharmacological treatments such as statins, ezetimibe, or PCSK9 inhibitors, tailored to individual risk profiles and health conditions to mitigate cardiovascular risk.
