How Low Can LDL Cholesterol Go on PCSK9 Inhibitors?
People with genetic mutations that leave them with an LDL cholesterol of 30 mg/dL live exceptionally long lives. Can we duplicate that effect with drugs? Data extrapolated from large cholesterol-lowering trials using statin drugs suggest that the incidence of cardiovascular events like heart attacks would approach zero if LDL cholesterol could be forced down below 60 mg/dL for first-time prevention and around 30 mg/dL for those trying to prevent another one. But is lower actually better? And is it even safe to have LDL cholesterol levels that low? We didn’t know until PCSK9 inhibitors were invented . Are PCSK9 Inhibitors for LDL Cholesterol Safe and Effective? I explore that issue in my video of the same name. PCSK9 is a gene that mutated to give people such low LDL cholesterol, and that’s how Big Pharma thought of trying to cripple PCSK9 with drugs. After a heart attack, intensive lowering of an individual’s LDL cholesterol beyond a target of 70 mg/dL does seem to work better t...
