    In this "Ask Me Anything" (AMA) episode, Peter takes a deep dive into thyroid health and explains why diagnosing and managing thyroid dysfunction is unusually complex. He begins with the basic biology of the thyroid gland and three commonly measured hormones—free T4, free T3, and TSH. He explains how T4 is converted to the active hormone T3 and the important functions T3 performs throughout the body. He also explains what reverse T3 is and when it may be useful to measure it. Peter then breaks down thyroid blood tests and their limitations and provides a practical framework for evaluating suspected thyroid dysfunction. He explains why symptoms alone are insufficient for diagnosis and reviews the criteria for diagnosing hypothyroidism, along with conditions that can mimic it. He also explores how hypothyroidism can be both underdiagnosed and overtreated and how to navigate subclinical hypothyroidism. Peter discusses treatment with T4 and T3, including why some patients continue to experience symptoms despite standard T4 replacement. He also explains how thyroid medications should be taken to optimize absorption. Additional topics include Hashimoto's disease, thyroid considerations during pregnancy, hyperthyroidism, the risks of excess iodine, and supplements marketed to support thyroid function. Finally, Peter offers guidance for patients who continue to feel unwell despite apparently normal thyroid tests.

    #407 ‒ Preventing cardiovascular and Alzheimer's disease: lowering LDL early, APOE4, and promising new therapies | Michael Davidson, M.D.

    View the Show Notes Page for This Episode Become a Member to Receive Exclusive Content Sign Up to Receive Peter's Weekly Newsletter Michael Davidson is a world-renowned cardiologist, lipidologist, and the founding CEO of NewAmsterdam Pharma. He begins this episode by sharing how his family history shaped his interest in lipidology and primary prevention. He explains why prevention should focus on causal drivers of disease rather than near-term risk and examines the causal relationship between LDL and atherosclerotic cardiovascular disease. Michael then traces the complicated history of CETP inhibitors—from the original rationale that raising HDL would reduce cardiovascular risk to the failures of torcetrapib, dalcetrapib, and evacetrapib—and explains how lessons from these trials ultimately led to the development of obicetrapib. He reviews the phase 2 and phase 3 trials of obicetrapib, its effects on LDL-C, apoB, LDL particle number, and Lp(a), the ongoing cardiovascular outcomes trial, and where the drug could fit alongside statins and other lipid-lowering therapies. Peter and Michael discuss the relationship between statins and diabetes risk, then turn to the potential role of obicetrapib in Alzheimer's disease prevention, exploring the genetics of APOE4 and CETP, cholesterol metabolism within the brain, and emerging biomarker data. Finally, Peter and Michael explore the benefits of omega-3 fatty acids and the challenge of delivering DHA to the brain, as well as ongoing work on klotho in preparation for clinical trials. They discuss the potential for AI to transform clinical trials and the scientific and financial challenges of developing new therapies for cardiovascular and neurodegenerative disease. We discuss: Michael's path to lipidology, and his passion for primary prevention [3:30];Reframing prevention around causal drivers rather than time horizon [9:30];What CETP inhibition does, the evolutionary biology of CETP, the HDL-raising rationale, and Pfizer's torcetrapib failure [15:00];Why raising HDL is thought to be beneficial, a quick review of the functions of HDL, and how this connects to torcetrapib [24:00];The graveyard of CETP inhibitors: Roche's dalcetrapib, Lilly's evacetrapib, and Merck's REVEAL trial [27:15];The causality of LDL in cardiovascular disease [34:30];Reviving obicetrapib at NewAmsterdam, and confirming the benefit is LDL lowering: the TULIP data, the abandoned statin-intolerance path, and the Mendelian randomization verdict on HDL [37:30];Phase 2 and phase 3 trials of obicetrapib—ROSE, BROOKLYN, BROADWAY, and TANDEM—and the PREVAIL outcomes trial, with the European and US approval paths [44:45];Discordance among LDL-C, LDL-P, and apoB with CETP inhibition, and obicetrapib's Lp(a)-lowering effect [50:30];Where obicetrapib fits in the lipid-lowering toolkit, the case against high-dose statins, and the problem of drug pricing [57:30];The case for obicetrapib in Alzheimer's: the APOE4 and CETP genetics, the animal models, and funding Alzheimer's research [1:03:45];Brain cholesterol metabolism and the APOE4 mechanism: the blood-brain barrier, astrocyte cholesterol efflux, the amyloid-tau cascade, the role of HDL, and why statins don't cause Alzheimer's disease [1:08:00];The biomarker evidence: the CSF pilot study, Alzheimer's as a disease of middle age, the pharma graveyard problem, and the p-tau 217 results from BROADWAY [1:17:45];Whether obicetrapib translates into clinical benefit for Alzheimer's disease: the risk of fooling yourself, the persistence of the amyloid dogma, ARIA in APOE4 homozygotes, and the next prevention trial [1:28:00];Fish oil, EPA, and DHA: the cardiovascular trials and the challenge of delivering DHA to the brain [1:32:00];Two open problems: using AI to reform clinical trials, and the statin–diabetes signal [1:41:15];What it takes to develop a drug, the biotech investment landscape, and the klotho program [1:48:15];Closing reflections: what to do if you carry APOE4, balancing motivation against over-testing, and the need for multiple therapies [1:55:15]; andMore.

    In this "Ask Me Anything" (AMA) episode, Peter delves into the critical subject of blood pressure, which is one of the three primary causes of atherosclerosis, along with high apoB and smoking. He begins by unraveling the nature of high blood pressure, its prevalence, and why it often goes undiagnosed. Peter describes in detail the proper way to accurately measure blood pressure and what determines a diagnosis. Next, Peter discusses the actionable steps one can take in response to high blood pressure, shedding light on the extent to which factors like weight loss, exercise, and nutrition can make an impact. He also explores the pharmacological options available and offers valuable insights on how to approach them.

    We discuss:

    • Blood pressure and other risk factors for cardiovascular disease [2:30];
    • Defining blood pressure and the purpose and meaning of a blood pressure measurement [5:45];
    • The implications of high blood pressure and the importance of maintaining an optimal level [10:30];
    • The importance of accurate measurements of blood pressure and how Peter approaches the care of patients at the very top range of "normal" [21:45];
    • The prevalence of high blood pressure—a hidden epidemic? [24:30];
    • The consequences of high blood pressure on cardiovascular health, brain health, kidneys, and more [24:45];
