Your veins and arteries carry the same blood. Same LDL. Same ApoB. Same everything. Yet veins almost never get plaque. Arteries constantly do.

Maybe you've seen the recent discussions about this. It's an interesting question that provides clues in cardiovascular science, and could challenge how we think about LDL and ApoB. 🧵 If ApoB-containing lipoproteins were "sufficient" to cause the disease, we should see plaque everywhere.

But we don't.

We only see it in the high-pressure, high-turbulence environment of the arterial system.

The real "experiment" happens during bypass surgery (CABG).

When a surgeon takes a pristine vein and grafts it into the arterial circulation, something changes.

Subjected to arterial pressure, that vein suddenly becomes susceptible to atherosclerosis.

Lowering TGs with pemafibrate doesnt lower CV events. Does that mean we can ignore TGs? No! A brief thread nejm.org/doi/full/10.10… Changing a lab value with a drug has NOTHING to do with changing it with a lifestyle approach Just look at HDL and CETP inhibitors.
