For Chinese adults with heart disease, having really low 'bad' cholesterol doesn’t seem to raise their risk of dying from heart problems or anything else — so pushing cholesterol levels way down with strong treatment might be safe.

What we've found so far suggests that very low LDL cholesterol may not be harmful for Chinese adults with heart disease. Our analysis of the available research shows no evidence that lowering LDL cholesterol to very low levels increases the risk of death from heart problems or other causes in this group [1]. We looked at 59 studies or assertions, all of which support the idea that aggressive cholesterol-lowering treatment is not linked to higher mortality in Chinese adults who already have heart disease [1]. None of the evidence we reviewed refuted this. This means the data we’ve examined so far leans toward the view that pushing LDL cholesterol down significantly — even to very low levels — does not appear to cause harm in this population. Still, our current analysis is based on a specific group: Chinese adults with existing heart disease. We can’t say from this evidence alone whether the same would hold true for people without heart disease, for other ethnic groups, or for long-term effects beyond what was studied. We also don’t have details on how low “very low” is, or what treatments were used, based on the summary alone. Because all the assertions we analyzed point in the same direction, the evidence we've reviewed leans toward safety with intensive cholesterol lowering in this group [1]. But we emphasize that this is our evolving understanding. As more data becomes available, our analysis may change. Practical takeaway: For Chinese adults with heart disease, there’s no sign from what we’ve reviewed so far that getting LDL cholesterol very low raises the risk of dying — so treatments aimed at lowering it aggressively may be safe.
