    What We Get Wrong About Poor Circulation (with Vascular Surgeon Dr. Jackie Majors)

    When people hear “poor circulation,” they often assume the answer is a procedure. Not so fast. In this episode of Knife Down, Dr. Jacqueline Majors and I talk about when opening a blocked artery helps, when it backfires, and why the real work of saving legs often starts long before the operating room. We get into what patients with poor circulation, blocked leg arteries, leg pain with walking, smoking-related vascular disease, and diabetes actually need to know. We talk about when a procedure helps, when it can make things worse, why not every blockage should be opened, and how lifestyle change, medical therapy, and careful decision-making can sometimes save a limb better than another stent. We also talk about what vascular surgery training gets right and what it misses, how Dr. Majors built a limb salvage-focused private practice, why strength training matters for vascular patients, and how to help people make meaningful changes without shame, perfectionism, or all-or-nothing thinking. Dr. Jacqueline Majors, MD is a board-certified vascular surgeon, Co-Owner, and Director of Limb Salvage at Zenith Vascular & Fibroid Center in Memphis, Tennessee. She is CEO of Vascular Excellence, PLLC, a consulting firm spanning expert witness work and locum tenens. She is also Founder and CEO of AnatomyPad, a patient education and operative planning product. She has performed multiple first-in-state procedures in Tennessee, including absorbable stents, retrievable BTK stents, advanced thrombectomy, and intravascular lithotripsy. Dr. Majors is a two-time Castle Connolly Top Doctor and multiple Top Doctor in Tennessee award recipient. She serves as an industry KOL, speaking nationally on drug-coated balloon therapy, intravascular lithotripsy, carotid disease, and limb salvage. She hosts Center of Excellence courses in Memphis, is the Vice Chair of the Young Physicians Association for the Tennessee Medical Association, and serves on the Board of the Memphis Medical Society. A former Division I athlete and nationally licensed soccer coach, she brings that same discipline to medicine, business, and patient care. Her philosophy: excellence is not an outcome. It is a discipline.

    They Don’t Want You Well. They Want You Worried.

    Are supplements safe? Not automatically. In this video, I explain why supplements are really drugs, why the industry has so little oversight, which products worry me most, and how I think about using supplements more safely in real life. I’m a board-certified vascular surgeon specializing in cardiometabolic prevention, and I do use supplements in practice — but in a targeted, evidence-informed way. Here I walk through the biggest myths about supplements, the real risks people ignore, the categories I side-eye hardest, and the framework I use to help patients choose products that are actually worth taking. If you’ve ever assumed that “natural” means safe, that a big retailer means quality, or that more supplements must mean better health… this one’s for you.

    When "Healthy" Is a Lie: @DrFordBrewer on Insulin Resistance, Hidden Plaque & His Prevention Pivot

    • Feeling “healthy” is not a screening test.   In this episode, Dr. Ford Brewer ( @DrFordBrewer ) tells the origin story: an ER doc who believed he was doing the right things—until he actually checked and found plaque. That discovery didn’t just change his health plan. It changed his entire job. He walked away from the adrenaline economy of emergency medicine and moved into cardiovascular prevention and teaching, because patching crises is not the same as stopping them.   We talk about: • The moment “I’m fine” stopped being believable • Why coronary heart (vessel!) disease continues to go undetected in millions of people • How statins fit into prevention (and why the decision isn’t one-size-fits-all) • Low-carb vs low-fat diets for cardiometabolic health—what Ford has learned over time • Lifestyle vs medication: what actually moves risk in the real world • How Dr. Brewer built a prevention mission and a YouTube channel to teach at scale • What he wants you to understand before you become “a patient” Timestamps: 00:00 Knife Down interview debut + double feature with @DrFordBrewer 01:00 ER → prevention: the case that changed everything 02:30 “Never a teacher… never a bean counter” (then: Johns Hopkins) 05:10 Ford’s wake-up call: finding his own plaque 07:15 “I walked the walk”: low-fat + endurance era (and why it didn’t protect him) 12:16 The CIMT moment: expected a clean slate… found plaque anyway 15:40 Metabolic disease hiding in plain sight (the real driver) 16:50 A1C misses a lot + “prediabetes but nothing to do” myth 22:50 Statins: fear vs intolerance + why he uses low doses (pleiotropic effects) 28:40 Plaque vs calcium score: CAC=0 ≠ “no plaque” 32:30 “It’s not heart disease — it’s vascular disease” 34:10 Nutrition: low-fat history → insulin resistance reality 38:10 Hyperinsulinemia: normal glucose, high insulin (why HOMA-IR can miss people) 45:00 Visceral fat, DEXA targets, and why “just walking” often isn’t enough 57:25 Low-carb vs low-fat + diet spectrum (his rule: if carbs hurt you, reduce them)   Follow Dr. Brewer here: @DrFordBrewer Disclaimer: Educational only, not medical advice.   #heartdisease #preventivemedicine #cardiovascularhealth #metabolichealth Other tools for optimal health (note these are affiliate links): Home BP Cuff: https://amzn.to/49Cq7rh Sonicare Toothbrush: https://amzn.to/3KllfMS WaterPik: https://amzn.to/4894Xi8 Apple Watch with sleep & HR monitoring: https://amzn.to/3XaUn5d Oura Ring with sleep, cycle, and recovery monitoring: https://amzn.to/4riyhLS Intake Breathing Nasal Support: https://amzn.to/48dfQQ1 Personal Blender: https://amzn.to/4pyNGGl True Nutrition Protein: https://oken.do/q2xzqeqw Glass Meal Prep Containers: https://amzn.to/4ocEPJ2 Sleep Mask: https://amzn.to/48fSJV5 Air Purifier: https://amzn.to/4puzTQZ Sign up for more information on my own practice here: https://corsighthealth.com/ ___________________________ 🧬 About Dr. Lily Johnston   Dr. Johnston is a double board-certified vascular and general surgeon in San Diego, specializing in metabolic and cardiovascular prevention.

    The Blood Pressure Myth That Won't Die: A Vascular Surgeon Reacts to @DrAlexWibberley ​

    Hypertension isn’t a mystery. It’s physics. And it’s quietly remodeling your arteries while you’re out here arguing with your salt shaker. In this reaction to @DrAlexWibberly, I’m mostly nodding along—because he nails the big idea: blood pressure is a mechanical force + a hormonal system problem, not just “too much sodium.” We talk through the three levers that create blood pressure (cardiac output, blood volume, vascular resistance) and why the “salt is the villain” storyline is incomplete for a huge chunk of adults—especially anyone with insulin resistance / metabolic syndrome. Then I add the vascular-surgeon angle: high blood pressure isn’t just a number on a chart. It’s endothelial injury, arterial stiffness, plaque progression, and the reason your brain/kidneys/heart don’t age gracefully. I also get into why processed food is the real trap: it hits you with salt + refined carbs in the same bite, so pressure rises… and then the kidneys stay locked in retention mode. Bottom line: meds work and save lives. But the long game is fixing the system—insulin down, nitric oxide up, whole foods in, ultraprocessed foods out—so your body can regulate pressure the way it was designed to. Watch Dr. Alex’s original video here: https://youtu.be/KwkG5Gh0M6k?si=DL6G_5JnHxbAt8O2  Watch next: https://youtu.be/-lt_2swYFhY?si=yek6DjdRv6HEB5Jh Not medical advice. Educational only. Talk with your clinician—especially if you’re already on blood pressure meds (because lifestyle changes can move the needle fast and your doses may need adjusting). Question for you: Have you ever cut salt “religiously” and your BP didn’t budge—until you cleaned up the carbs/processed food?

    HIIT vs Heart Plaque: Randomized Trial Deep Dive

    In this research report deep dive, I walk through a randomized trial that asked a very specific, very modern question: can high-intensity interval training (HIIT) measurably change coronary atherosclerotic plaque—not just your VO₂ max? We go line-by-line through the paper: who they enrolled, what the HIIT protocol actually was, how they measured plaque (and plaque type), what outcomes moved, what didn’t, and the limitations that matter before you turn “exercise is medicine” into a personality. Also: this is ~40 minutes of dense research nerdery. So if you’re here for quick answers, you took a wrong turn. If you’re here for receipts, welcome.

    ChatGPT’s Medical Reply - Vascular Surgeon Fact Check!

    A subscriber asked about statins—so I made ChatGPT answer first… and then I fact-checked it as a vascular surgeon. We’re talking cholesterol, LDL, ApoB, plaque growth and plaque rupture, and what “prevention” actually means when the goal is avoiding the first heart attack (or the next one). We’ll cover when statins make sense, when they’re oversold, and why “my numbers are fine” doesn’t always mean your arteries are fine. This is AI in healthcare with a reality check.

    New Drugs Cut Lp(a) Over 90%...Will They Prevent Heart Attacks?

    In this video, we explore the exciting pipeline of drugs targeting lipoprotein a and its implications for cardiovascular disease prevention. We'll examine how these cholesterol drugs are designed to work, including those utilizing sirna technology, and discuss the reasons for both enthusiasm and caution regarding this medical breakthrough. This discussion aims to clarify the current landscape of new treatments and what questions still need answers. Here’s what I cover: - The strategy for lowering Lp(a): stop production vs block assembly (it’s basically all in the liver) - The late-stage / headline agents and trials:     - Pelacarsen (ASO) — Lp(a)HORIZON     - Olpasiran (siRNA) — OCEAN(a)     - Lepodisiran (siRNA)— ACCLAIM-Lp(a) (enrolling)     - Zerlasiran / SLN360 (siRNA) — development in flux     - Muvalaplin (oral assembly inhibitor)— KRAKEN (phase 2) - Why I’m genuinely hopeful: plasmapheresis is a “proof-of-concept” that lowering Lp(a) *might* reduce events (with important confounders) - Why I’m still skeptical until outcomes data lands: the graveyard of “should-have-worked” drugs (CETP inhibitors, canakinumab—great biomarker/endpoint signals, messy real-world tradeoffs) - My 5-question framework for evaluating any new cardiometabolic drug the moment it hits the market:     1. What problem does it actually solve—and how big is the benefit?     2. How strong/unbiased is the evidence (and do we have outcomes)?     3. Who is the right target (and who wasn’t in the trial)?     4. What are the tradeoffs (side effects, cost, duration, unknowns)?     5. Would I take it? Would I give it to my mom—under what conditions?
