You're in the clear, right? Not so fast.In this episode, Optispan Clinical Director Dr. Nicki Byrne sits down with Dr. Kim Brockenbrough, board-certified cardiovascular radiologist, 25-year veteran of vascular imaging, and CEO of CardiaVision, for a conversation that challenges one of the most common assumptions in preventive cardiology.If you care about cardiovascular longevity, and you should, because heart disease remains the leading killer, this is the imaging conversation you didn't know you needed.Timestamps:00:00 — Cold open: The 48-year-old runner with an 80% blockage and a zero calcium score00:54 — Dr. Nicki Byrne introduces Dr. Kim Brockenbrough & CardiaVision01:45 — Dr. Brockenbrough's background: 25 years of vascular imaging02:35 — Cardiovascular disease through a longevity lens: imaging vs. labs vs. functional testing03:24 — The lifecycle of plaque: from fatty deposits to rupture and heart attack04:21 — Why soft plaque is more dangerous than calcified plaque (SCOT-HEART 2020)05:14 — How calcium scores are used in clinical practice — and where they fall short06:18 — The only way to see soft plaque non-invasively: coronary CT angiography (CCTA)07:08 — Which populations are most at risk of a false sense of security from calcium scoring08:03 — What a CCTA can tell you that a calcium score can't09:43 — How often should patients follow up with repeat scans?10:28 — Higher vs. lower dose radiation protocols — and why Dr. Brockenbrough chooses higher dose11:17 — Risks of CCTA: contrast reactions, kidney considerations12:15 — Stress tests vs. CCTA: why a negative stress test is a very low bar13:21 — Soft plaque that isn't flow-limiting: small emboli, dementia, and congestive heart failure15:36 — Medications that reverse plaque: statins, PCSK9 inhibitors, and the LOCATE trial16:23 — LDL reduction and plaque regression: what the data shows17:08 — High-intensity statins vs. Repatha — tolerability, efficacy, and the price drop18:27 — When OptiSpan reaches for PCSK9 inhibitors: ApoB, LDL, Lp(a), ApoE4, and significant disease19:22 — Why a rising calcium score on a statin is exactly what you want to see20:25 — AI plaque quantification tools: promise, limitations, and validation concerns22:54 — Has AI ever changed Dr. Brockenbrough's read?

Dr. Matt Kaeberlein breaks down the conversation in real time, fact-checking claims about peptide efficacy, FDA regulation, and the growing black market for compounded peptides.What does the science actually say? What did RFK get right and where did the conversation miss the mark? Dr. Kaeberlein cuts through the noise with a scientist's lens, covering everything from BPC-157 to GLP-1 agonists to the FDA's Category 2 bulk drug substances list.If you're navigating the peptide space and want clarity over hype, this one's for you.Timestamps:00:00 — Intro & Episode Overview01:06 — RFK on Joe Rogan: The Peptide Conversation Begins02:06 — First Fact Check: "We Know Peptides Work"03:50 — GLP-1 Agonists: The Exception, Not the Rule05:05 — RFK's Personal Peptide Experience06:32 — The FDA's Bulk Drug Substances List Explained08:32 — FDA Category 2: What It Actually Means09:21 — The Peptides That Were Banned From Compounding10:18 — Did the FDA Consider Safety?

What does over 18 months of precision medicine actually look like in practice? In this episode of the Optispan Success Story Series, Dr. Matt Kaeberlein sits down with Carlos Pinto, a tech executive and early Optispan client, to trace his longitudinal health journey from metabolic warning signs to measurable, sustained transformation. Carlos shares how a decade of overlooked biomarkers, a post-pandemic health decline, and a single panic attack became the catalyst for a data-driven approach to his own biology. Together, he and Dr. Kaeberlein review real DEXA, lipid, metabolic, and environmental biomarker data, unpacking what moved the needle, what didn't, and why the answer was rarely simple. This conversation is a candid look at what it means to become your own best health advocate, not through quick fixes, but through personalized, longitudinal learning.Timestamps:0:00 – Cold open & highlights0:50 – Welcome & Carlos's background in tech leadership2:15 – How career ambition displaced health in his 20s and 30s3:39 – A panic attack as the turning point: connecting mental and physical health4:24 – A previous medical wellness program: what worked and what was missing6:34 – Arriving at OptiSpan: intention, mindset, and expectations7:15 – Gateway Day: comprehensive baseline testing and initial surprises8:51 – Early metabolic lessons: CGM data, glucose spikes, and dawn effect11:32 – Confronting white coat hypertension with 78 data points13:28 – How stress, sleep, and nutrition interact to drive metabolic dysfunction15:44 – Personal experimentation as methodology: berberine, time-restricted eating, and fish17:09 – Mercury toxicity from fish consumption: a case study in biomarker surveillance18:33 – Stress management protocols: walking, meditation, and measurable outcomes19:49 – Statin introduction: the role of medication as a tool, not a failure20:27 – DEXA results: visceral fat reduction, body fat loss, and lean mass gain24:17 – Lipid profile transformation: ApoB from ~115 to 70, LDL from 160 to 7425:57 – A1C trajectory and the complexity of glucose optimization30:01 – Reframing medication: proactive use vs. reactive disease management31:29 – Mercury biomarker deep dive: from 2.4 to 16 and back to 232:21 – Goals for the future: sustainability, muscle retention, and mental clarity36:30 – Lineage biological age algorithm: from mortality risk of 54 to 5239:27 – Closing reflections: health as a lifelong trajectory, not a program

Peptides are everywhere in longevity and functional medicine, but what does the law actually say? In this episode, Dr. Matt Kaeberlein breaks down what a peptide is and the complex regulatory landscape governing peptides in the United States, from FDA approval frameworks to the legal gray zones surrounding compounding pharmacies and unapproved substances.Drawing on the Federal Food, Drug, and Cosmetic Act and real-world enforcement cases, this episode offers a clear-eyed, non-judgmental examination of what is legal, what is tolerated, and what carries genuine risk for physicians, pharmacies, and patients alike.
