In adults with diabetes who do not have advanced artery disease, a medication called evolocumab lowers the risk of dying from any cause over five years compared to a placebo.
Mechanism
Synthesis from 1 study
This drug helps the liver remove more bad cholesterol from the blood by keeping more cleanup receptors active. With less cholesterol building up in artery walls, dangerous blockages are less likely to form and rupture. Fewer heart attacks and strokes mean people live longer.
Most probable mechanism
A drug blocks a protein that normally removes cholesterol-clearing receptors from the liver, so more receptors stay on the liver surface to pull cholesterol out of the blood. With less cholesterol circulating, fatty deposits in artery walls grow slower and become less likely to rupture and cause heart attacks or strokes, which reduces the chance of dying from heart-related causes.
A monoclonal antibody binds to and neutralizes PCSK9 protein in the bloodstream
Neutralized PCSK9 cannot tag LDL receptors for destruction in liver cells
LDL receptors are recycled to the surface of liver cells instead of being degraded
Increased LDL receptor density enhances clearance of low-density lipoprotein cholesterol from the blood
Lower blood cholesterol levels reduce the deposition of lipids into the arterial wall
Reduced lipid accumulation slows the initiation and progression of atherosclerotic plaques
Stabilized, smaller plaques are less likely to rupture and trigger blood clots
Fewer clot-related blockages in heart or brain arteries reduce the incidence of fatal heart attacks and strokes
