Greg KatzGUEST
It's gonna be really interesting, and these are gonna be important questions because how many patients d- uh, exist in this world who have had an event and have high Lp(a) and are wondering, "What do I do with this information? How do I make sense of it?" I have conversations with other doctors all the time about, "What do you do with this value for this patient? They've had an MI.

Greg KatzGUEST
Do I do anything else? Is my-- Should my LDL goal be 40? Should it be 55? Should I treat a little bit more aggressively with blood pressure?" You know, the high-sensitivity CRP being so low in this group says to me there's probably a lot less insulin resistance visceral fat than in a lot of the cohorts that I treat because so much of that in the real world, those mildly elevated high-sensitivity CRPs are just driven by the low-grade inflammation associated with visceral fat and obesity.

Greg KatzGUEST
And the other sort of one hypothesis that we haven't touched on that I think needs to be brought up is, are we sure pelacarsen didn't have any non-Lp(a)-related cardiovascular impact? The answer is probably not because all of the preliminary data from phase one, phase two didn't suggest it.

Greg KatzGUEST
But the history of medicine is sort of littered with things that seemed like they should have worked and then didn't work when they were ultimately tested.

So a coronary artery calcium score, or a CAC score, is a ver- It's a very controversial area in medicine, and I think a lot of cardiologists have been very eager to sort of, like, jump on the bandwagon of get a lot of imaging, and there have been a lot of smart people who look at that as the cardiologists are insane because the RCT data just, like, is not there to support that as an intervention.

Greg KatzGUEST
And so, you know, the, a c- a CAC score, there's two different types of imaging of the coronary arteries that we can do with a CT scan.

Greg KatzGUEST
That is a low-radiation, zero-contrast chest CT that basically looks to see is there any calcium buildup in the arteries around the heart.

So considering that there may be some underlying insulin resistance present, even with his, quote, "normal A1c," for a motivated patient like Gary, is there any value to checking like a, a fasting insulin or a HOMA-IR, or can you just use the, the triglyceride to HDL ratio to spot the danger?

Greg KatzGUEST
Well, a calcium score is looking to see if you have any signs of hardening of the arteries.
