Preventing and treating cardiovascular disease (Lipid Series – Part 3) | Dr Thomas Dayspring

Listen Now

In Episode #253, Dr Thomas Dayspring joins me to round out our three-part masterclass on blood lipids and atherosclerotic heart disease. In Episode #251, we covered what blood lipids are and what happens when things go wrong within the lipid transportation system, and in Episode #252 we looked towards how to test and understand your blood lipids as an individual. Make sure to listen to those episodes first.

“If there was widespread improvement in nutrition and lifestyle there would certainly be a lot less [of] many chronic diseases, including atherosclerotic heart disease. But by no means can you eliminate this with lifestyle alone.”

In this episode, Part Three of the lipid series, we discuss interventions to lower risk of atherosclerotic cardiovascular disease (ASCVD). Both Dr Dayspring and I believe in a lifestyle-first approach to lipid optimisation. As discussed in previous episodes with the likes of Dr Gil Carvalho and Dr David Jenkins, there is no doubt that nutrition is the most powerful lifestyle tool we have to dramatically lower ApoB. In some cases, certain people will be able to lower their ApoB by around 30% through diet alone.

In other cases, where people have a genetic predisposition to higher ApoB, or cannot sustain dietary changes, pharmacotherapy is required to optimise lipid levels and achieve low risk of ASCVD. This conversation is designed to help you better understand the treatment options available if you do require a pharmaceutical approach. As Dr Dayspring says: you need to be your own advocate, which means developing some level of understanding to gain more autonomy over your health.

At this point in the lipid series, Dr Thomas Dayspring needs no introduction. He is a Fellow of the American College of Physicians and the National Lipid Association. He is certified in internal medicine and clinical lipidology and has brought an invaluable wealth of knowledge to this series. As you’ve seen in Part One and Part Two of this series, he is also incredible at communicating complex information in an accessible way, supported by the illustrations you’ll see in the YouTube versions of the podcast.

Given Dr Dayspring’s expertise in both research and practice, this episode focuses almost exclusively on the available pharmaceutical drugs to lower ApoB, an elevation of which is essential for developing atherosclerosis. We walk through four main drug classes – ezetimibe, statins, bempedoic acid, and PCSK9 inhibitors – discussing their mechanism of action, effectiveness, and safety profile.

We cover the history of treatment options for ASCVD, tracking the drugs that have been available over time and the main treatment options available now. We also discuss current trials that are running, potential interventions in the future, and much more.

Specifically, we discuss:

  • Evolution of cardiovascular disease treatments (03:42)
  • Are we becoming a drug-dependent society? (07:30)
  • Bile acid sequestrants, statins, and more (13:54)
  • Cholesterol-lowering drugs and cognition (35:12)
  • Is Bempedoic acid a good statin alternative? (47:39)
  • Ezetimibe and nuances you should know (55:46)
  • PCSK9 inhibitors (1:03:32)
  • Do statins increase the risk of diabetes? (1:14:58)
  • Gene therapy targeting PCSK9 (1:19:20)
  • Pelacarsen for lowering Lp(a) (1:23:48)
  • Can we take drugs that raise HDL to lower cardiovascular disease risk? (1:26:38)
  • HDL and atherosclerosis (1:34:59)
  • Elevated triglycerides and atherosclerosis (1:46:48)
  • Takeaways (2:05:12)
  • Outro (2:08:31)

In cases where someone already has existing ASCVD and ApoB target levels are much lower, it is much more likely that pharmacotherapy will be required to restore physiologic levels (the level we are born with) of ApoB. With this in mind, my personal philosophy on lipid optimisation is to not look at this as an either/or scenario. My advice is to make as many sustainable dietary changes as you can – and then, if required, use the least amount of pharmacotherapy to achieve an optimal ApoB (<80mg/dl if low risk, <50 mg/dl if moderate to high risk).

The rationale for this is two-fold. One, the dietary changes required to improve ApoB will also benefit other risk factors for chronic disease. Two, while lipid lowering drugs are incredibly effective at lowering risk of ASCVD, they are not without risk.

If you are currently struggling with ASCVD or are at risk, I hope you found this episode and series empowering. Even if this does not appear to be a concern for you in the foreseeable future, it’s important to be equipped with this knowledge on one of the Western world’s biggest killers. Dr Dayspring offered extremely well-informed insight into this topic over the course of this series, and I am grateful to have had a field leader on the show to embark on this deep dive.
