Rethinking Prevention in ASCVD Through Cumulative LDL Exposure

The panelists revisit the concept of cumulative LDL-C exposure as a central driver of atherosclerotic risk, emphasizing that prevention must begin earlier and continue consistently throughout life. The experts explain that ASCVD develops over decades, with long-term exposure to elevated LDL-C creating a continuous burden on the vascular system. They discuss emerging data showing that earlier LDL-C lowering yields greater benefit than later intervention, even when the same LDL targets are eventually reached. This reinforces the principle that both the magnitude and duration of LDL-C reduction determine clinical outcomes. The panelists suggest that prevention frameworks should expand beyond “high-risk” patients to include younger adults with elevated LDL-C or familial predisposition, aiming to limit lifetime cholesterol exposure. They conclude that achieving and maintaining low LDL-C levels over time—rather than short-term correction—represents a paradigm shift in ASCVD prevention strategy and population health management.
