What is the target LDL level recommended for patients with known coronary heart disease?

The target LDL level recommended for patients with known coronary heart disease is under 100 mg/dL. This guideline is supported by multiple clinical studies indicating that lower LDL levels correlate with decreased rates of cardiovascular events in patients who have a history of coronary heart disease.

The rationale for this target is based on the understanding that these patients are at a higher risk for further cardiovascular complications, and achieving an LDL level below 100 mg/dL is associated with improved outcomes. Evidence from the ATP III guidelines and subsequent updates emphasize that this threshold effectively aids in the reduction of major cardiovascular events by promoting better lipid management.

Patients with known coronary heart disease may also benefit from even more aggressive lipid-lowering strategies, but the primary target is clearly established as less than 100 mg/dL. This is a critical aspect of preventive care and management in cardiology, reflecting a comprehensive approach to reducing morbidity and mortality associated with coronary artery disease.
