Statins have been shown to reduce the risk of stroke in which population?

• A. People with normal LDL levels
• B. People with very high LDL levels only
• C. People who are noncompliant with diet
• D. People with uncontrolled diabetes regardless of LDL

Answer: (A)

Statins reduce stroke risk by more than just lowering LDL. They stabilize atherosclerotic plaques, reduce vascular inflammation, improve endothelial function, and lower thrombosis risk. Because of these multiple effects, their protective impact shows up in people with different kinds of vascular risk, not only in those with high LDL levels.

There is evidence that statins can lower the chance of stroke even when LDL is within normal limits, particularly in individuals who have other strong risk factors such as elevated inflammatory markers or a history of vascular events. For example, trials in people with normal LDL but other risk factors have demonstrated a reduction in major cardiovascular events, including stroke, with statin therapy. The benefit is even more evident in primary prevention for those at high risk and in secondary prevention after a stroke, where statins consistently reduce recurrent stroke risk.

So, the takeaway is that statins’ stroke-protective effects extend beyond just those with high LDL; they can benefit people with normal LDL if their overall cardiovascular risk is elevated.
