What this video covers
Since you clicked on this video, I have to assume you’ve heard the term LP little A. But to get everyone up to speed, LP little A is a major risk factor for heart disease and the new hotness in the cardiology world. In particular, LP little A is a causal risk factor for atherosclerosis, the buildup of plaque in the arteries of your heart. In fact, on a per particle basis, LP little A is thought to be at least six times as a causing heart disease as LDL cholesterol containing particles.

Key points, in the speaker’s own framing
- These blood clots can block blood vessels and LPA can promote their growth leading to increased risk of cardiovascular disease.
- The goal is to reduce other risk factors, including with healthy lifestyle practices to reduce overall risk.
- If LP little A acts as a risk multiplier of sorts, increasing your relative risk from some baseline, then if the baseline risk is lower, the absolute increase in risk is also lower.
- A 50% relative increase in risk means your absolute risk increases to 15%, it increases by five.
- A 50% relative increase in risk means your absolute risk only increases by.5%.
- Data suggests that there’s a synergistic relationship whereby people with higher LP delay and chronic inflammation are at higher risk than those with high LP delay but lower inflammation.
