Assessing your risk of cardiovascular disease (Lipid Series – Part 2) | Dr Thomas Dayspring

Listen Now

Last week, I sat down with Dr Thomas Dayspring to begin a three-part masterclass in atherosclerosis and blood lipids. In Episode #252, Dr Dayspring returns to continue this journey, this time shifting the focus from the causes of cardiovascular disease to more individualised applications. This episode is all about understanding where you lipids are now so you can then work out the best strategy to optimise them.

“Lipidologists are now understanding [what] we have to do: recognise the risk for the fire and get on it with whatever equipment you have to ASAP.”

There is so much noise online about the tests that matter, the ones that don’t, and which biomarkers to look out for. In this episode, Dr Dayspring clearly outlines the three lipid tests that you should take to best assess your risk of atherosclerotic cardiovascular disease – and importantly, the ones you don’t need.

Dr Thomas Dayspring is a Fellow of the American College of Physicians and the National Lipid Association. He is certified in internal medicine and clinical lipidology, and as we saw in last week’s episode, adept at communicating complex information in an accessible way. Make sure you watch or listen to Episode #251 first to get the background you need to better understand this conversation.

“If you have any cardiovascular risk, eating a good, healthy diet is good for your heart in the long run, no matter what it’s doing to any given biomarker.”

In this episode, you’ll learn about the lipid tests that matter and the ones that don’t. Dr Dayspring also explains the importance of early testing, including when to do your first lipid test and how often (if at all) you should retest. We discuss why ApoB is a superior test to LDL-C, whether LDL particle size matters, and if HDL-C is an important test.

We also cover the importance of measuring triglycerides; exactly how to request ApoB and LP(a) tests from your doctor; targeting ApoB levels for low- and high-risk patients; and how to test if someone is a hyper-producer of cholesterol and/or a hyper-absorber.

On top of all this, we walk through a few different avatars that many will find relevant and how Dr Dayspring would advise these people to proceed.

Specifically, we discuss:

  • Intro (00:00)
  • What is Lp(a), and why you need it checked? (02:05)
  • Does diet influence Lp(a)? (20:36)
  • The oxidized phospholipid test (29:00)
  • Early intervention and atherosclerosis screening for children (31:24)
  • The tests helpful in predicting cardiovascular disease risk (40:27)
  • Discordance between ApoB and LDL-cholesterol (52:35)
  • Normal range of ApoB levels for a healthy young person (1:03:14)
  • Does atherosclerotic plaque ever disappear? (1:16:52)
  • Triglyceride: HDL ratio vs ApoB test (1:22:15)
  • Screening women in their 30s (1:29:31)
  • Screening women in their 70s (1:37:23)
  • What causes elevated ApoB (1:39:25)
  • Do phytosterols help manage cholesterol? (1:58:55)
  • Secondary prevention (2:07:08)
  • The obviously misunderstood case of ApoB (2:20:45)
  • Outro (2:22:35)

As we press forward with the blood lipid series, I hope you are finding value in this deep dive. This series is all about equipping you with the knowledge you need to protect yourself against the prolific disease that is atherosclerotic CVD, and the sooner you can action this knowledge, the fewer cholesterol years you will bank up. Make sure to tune in to next week’s episode, where we will cover the interventions you can make to optimise your lipids.
