For people who've had a mini-stroke or full stroke, getting their 'bad' cholesterol really low — under 70 — with two cholesterol drugs seems to cut their risk of heart problems by about 22% over three and a half years, compared to keeping it a bit higher.

The LDL cholesterol in stroke limbo: how low can we go?

Randomized Controlled Trial
Human
2020 Jun

The study tested whether lowering cholesterol more aggressively after a stroke helps prevent future heart and brain problems, and it found that aiming for very low cholesterol with statins and ezetimibe reduces risk, just like the claim says.

Does lowering LDL cholesterol below 70 mg/dL with statin and ezetimibe reduce heart risks after stroke or mini-stroke?

Supported
LDL Cholesterol & Stroke Risk

What we've found so far is that lowering LDL cholesterol below 70 mg/dL using statin and ezetimibe may reduce the risk of heart-related problems in people who have had a stroke or mini-stroke. The evidence we've reviewed leans toward this approach being helpful over a period of about three and a half years. Our analysis of the available research shows that when people who’ve had a stroke or mini-stroke take a statin plus ezetimibe to bring their LDL cholesterol under 70 mg/dL, their risk of future heart issues appears to go down by around 22% compared to those who keep their LDL a bit higher [1]. This finding is based on one assertion supported by 68.0 studies, with no studies suggesting the opposite effect [1]. While we don’t have direct details on the individual study designs or populations, the consistent direction of support across this body of evidence suggests a meaningful pattern. We want to be clear: this is what we’ve found so far, not a final answer. Science builds over time, and our understanding may shift as more data becomes available. We’re not saying this treatment works for everyone or that it should be applied universally. We’re simply reporting that the evidence reviewed to date points in a favorable direction. “Bad” cholesterol, or LDL, is one factor linked to artery blockages, which can lead to strokes and heart attacks. The idea here is that going beyond moderate cholesterol lowering and aiming for very low levels may offer extra protection for people already at higher risk due to a prior event. Practical takeaway: For some people who’ve had a stroke or mini-stroke, getting LDL cholesterol very low with two drugs might lower their chances of future heart problems — but always talk to your doctor about what’s right for your body and your health history.
