EP360: STOP-CA to Stop Statin Bashing

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction: Warrick Bishop hosts this episode to discuss an unconventional application of statin therapy—using statins alongside chemotherapy to reduce cardiotoxicity in cancer patients. The episode focuses on the STOP-CA trial, a landmark double-blind, placebo-controlled study examining whether atorvastatin can protect the heart from damage caused by anthracycline chemotherapy in lymphoma patients. Key Takeaways: Anthracycline chemotherapy, used to treat lymphomas, carries a 10-15 fold increased risk of heart failure due to its cardiotoxic effects on cardiac function. The STOP-CA trial (Statins to Prevent CardiotOxicity Associated with Anthracyclines) was designed to test whether atorvastatin could protect cardiac function in patients receiving anthracycline therapy. Study inclusion criteria required participants to have Hodgkin's or non-Hodgkin's lymphoma, be scheduled for anthracycline therapy, and be 18 years or older, with strict exclusion criteria to maintain study integrity. The primary endpoint measured was a reduction in left ventricular ejection fraction of 10% or more (from approximately 60% down to 50%). Results showed compelling protection with the statin group: only 9% of atorvastatin-treated patients experienced significant cardiac dysfunction compared to 20% in the placebo group—more than twice the rate. The statin group demonstrated 2-3 times greater protection against progression to significant left ventricular dysfunction reduction compared to placebo. The protective mechanism is believed to involve statins' anti-inflammatory properties, which may mitigate inflammatory cellular responses triggered by chemotherapy. Cancer patients undergoing chemotherapy should discuss with their treating physicians whether starting or continuing statin therapy could provide cardiac protection. Those already taking statins who require chemotherapy may benefit from continuing statin therapy, pending specialist advice. Read more

EP359: Defining Family History and High Cholesterol

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Episode Summary Introduction: Dr. Warrick Bishop hosts this educational podcast episode focused on cardiovascular health literacy. In this installment, Dr. Bishop clarifies two critical concepts for patients concerned about heart disease risk: what constitutes significant family history and how to properly understand cholesterol levels. The episode aims to help listeners distinguish between meaningful risk factors and common misconceptions that may unnecessarily worry them. Key Takeaways: Significant family history of cardiovascular disease only applies to first-degree relatives (parents, siblings, or children) who experienced cardiac events at relatively young ages: males at 55 years or younger, or females at 60 years or younger. Cardiovascular events occurring in distant relatives at advanced ages (such as a great-uncle at 90) do not constitute meaningful family risk for the individual being assessed. High cholesterol must be evaluated differently depending on whether an individual has already experienced a cardiac event (secondary prevention) or has not (primary prevention). For secondary prevention patients (those who have had a cardiac event), high cholesterol is defined as LDL cholesterol above 1.4 millimoles per liter, which is lower than previous guidelines of 1.8. In primary prevention, cholesterol categories range from desirable (total cholesterol under 5.2) to very high (total cholesterol over 7.8), with Australian guidelines recommending an LDL target of 2.0 millimoles per liter or less. Cholesterol levels should be understood as a continuum rather than rigid cutoffs; as LDL cholesterol increases, the risk of plaque formation and cardiovascular events increases proportionally. Dr. Bishop uses a car-rusting analogy to explain LDL cholesterol: prolonged exposure to high cholesterol (like salt air) increases plaque buildup over time, similar to rust formation. Lifetime LDL cholesterol exposure is an important concept; keeping cholesterol lower over a person's lifetime reduces cumulative risk of atheroma development. Individual outcomes vary; some people with low cholesterol develop arterial plaque while others with high cholesterol remain plaque-free, highlighting that cholesterol is one of multiple cardiovascular risk factors. Individuals with very high cholesterol levels, particularly those with familial hypercholesterolemia and positive family history, should be treated proactively to prevent future cardiovascular events.

EP358: Perry Eckert and Regeneration Technologies

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction Dr. Ulrich Bishop welcomes Perry Eckhart, Master Franchisor for Australia and New Zealand, for a second episode discussing OsteoStrong's complementary technologies beyond the core Spectrum machines. Building on their previous conversation about axial loading and bone/muscle strength, this episode explores four additional wellness technologies designed to shift the body from a stress state to a relaxed, healing state. Key Takeaways: OsteoStrong's Spectrum machines activate the sympathetic nervous system (fight-or-flight), building bone and muscle strength but also increasing cortisol, which causes inflammation and stress-related damage. The center's complementary technologies are specifically designed to activate the parasympathetic nervous system, reducing cortisol and promoting relaxation and healing to counterbalance the stress response from workouts. Hydro massage beds use powerful water jets to provide 40 minutes of equivalent massage from four people in just 10 minutes, improving blood flow, lymphatic movement, and leaving users with noticeably improved mood. Red light therapy at 650 nanometers wavelength penetrates cells to activate cytochrome P in mitochondria, increasing cellular energy production and reducing inflammation; it also regulates circadian rhythms and can be used throughout the day for improved mitochondrial health. Normatec compression boots use pneumatic compression technology to massage legs from toes to hips, improving lymphatic flow, reducing swelling and inflammation, and aiding recovery for athletes and people with standing-intensive jobs. Pulsed electromagnetic field (PEMF) therapy mats recreate the Earth's natural magnetic field that modern humans are increasingly insulated from, helping regulate brainwave states and reduce inflammation while "earthing" the body. Humans are fundamentally electrical beings, with mitochondria converting food-derived nutrients into ATP that powers cellular electricity; magnetic field exposure and proper earthing are critical for optimal health. Modern lifestyle factors—rubber-soled shoes, carpeted floors, cars, lack of gardening—disconnect us from Earth's beneficial magnetic field, contributing to chronic health problems that PEMF therapy can address.

EP357: Perry Eckert and OsteoStrong

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Episode Summary Introduction Dr. Warrick Bishop hosts Perry Eckhart, master franchisor for OsteoStrong Australia and New Zealand, to discuss the unique health and wellness program designed to improve bone and muscle health. As a franchise co-owner himself, Dr. Bishop provides an insider's perspective while allowing Perry to explain OsteoStrong's origins, methodology, and vision for the future of preventative medicine. Key Takeaways: OsteoStrong uses specially designed Spectrum machines that apply axial loading (loads through the bone's axis) to trigger osteogenesis and naturally improve bone density, often reversing osteopenia and osteoporosis within 6-12 months. The program achieves dramatically higher loads than conventional gym equipment by positioning users at their biomechanically strongest point (approximately 120-degree joint angles), where muscles are 8-10 times stronger, enabling loads exceeding 500kg safely. Axial loading must exceed 4.2 multiples of body weight on the femur and hips to trigger bone density improvement, based on peer-reviewed research, distinguishing OsteoStrong from high-impact aerobics that only slow bone loss. The program requires only 10 minutes once per week and involves a single maximal effort rep per machine with no moving parts, resulting in an exceptionally low injury rate (400,000+ sessions in Australia without injury). A recent Monash University study showed female participants over 55 with osteoporosis achieved average strength increases of 124-145% across machines in eight months. Members report benefits beyond bone health, including reduced joint and back pain, improved balance, enhanced grip strength, and better blood glucose regulation due to increased muscle density. Perry's personal motivation stems from family history—his grandmother died following a hip fracture and his mother developed severe lifelong osteoporosis—driving his commitment to preventative medicine. Perry adopted a "biohacking" philosophy focused on optimizing healthspan (period of good health) rather than just lifespan, recognizing that modern sedentary lifestyles fail to activate the natural adaptive responses to environmental stimulus that built bone density in ancestral humans. The business model represents a "blue ocean" opportunity with proprietary robotic equipment unique in the marketplace, unlike saturated fitness assessment markets. Read more

EP356: Impact of Statins on Ubiquinone or Coenzyme Q 10

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction: Warwick Bishop hosts this episode to explore the biochemical processes involved in statin therapy, specifically examining the mevalonate pathway and its downstream effects on important molecules like coenzyme Q10 (ubiquinone) and vitamin K2. The episode focuses on whether reduced coenzyme Q10 levels from statin use contribute to muscle-related side effects and discusses emerging alternative therapies. Key Takeaways: Statins work by inhibiting the mevalonate pathway, which converts acetyl-CoA through a series of reactions into cholesterol and other vital compounds. Both coenzyme Q10 (ubiquinone) and vitamin K2 (menaquinones) are produced downstream in the same metabolic pathway affected by statins. Coenzyme Q10 is essential for cellular energy production, particularly in the electron transfer pathway within mitochondria. A 2022 study of 80 people with statin-related muscle symptoms found no clear link between coenzyme Q10 levels and muscular symptoms. CoQ10 supplementation did not significantly alter plasma or muscle tissue CoQ10 levels in the study, suggesting limited efficacy for statin-induced muscle pain. Despite lack of strong evidence, individual patients may still benefit from CoQ10 supplementation and should be encouraged to try it if experiencing muscle discomfort. Bempedoic acid is an emerging alternative therapy that works upstream in the same pathway, blocking acetyl-CoA conversion at the ATP citrate liase enzyme. Bempedoic acid acts only in the liver, potentially avoiding the muscle-related side effects that occur with statin therapy. Read more

EP355: Vitamin K and Lipid Lowering Therapy

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction Dr. Ulrich Bishop hosts this episode to explore the often-overlooked relationship between vitamin K and cholesterol-lowering medications. The episode examines how fat-soluble vitamins like vitamin K play crucial roles beyond blood clotting, particularly in bone health and calcium regulation, and how common lipid-management drugs may inadvertently impact vitamin K status in the body. Key Takeaways: Vitamin K is a fat-soluble vitamin essential not only for blood clotting but also for bone health and calcium regulation through activation of the protein osteocalcin. Vitamin K activates matrix GLA protein (MGP), a potent inhibitor of soft tissue calcification, helping ensure calcium deposits in bones rather than in arteries or heart valves. Vitamin K supports bone health by promoting osteoblast (bone-building cell) differentiation, reducing osteoclast formation (bone-resorbing cells), and decreasing inflammatory processes at the bone surface. Statins, which are HMG-CoA reductase inhibitors, may reduce the body's production of menaquinone-4 (vitamin K2) by blocking the enzymatic pathway that converts acetyl-CoA to downstream molecules needed for vitamin K synthesis. Ezetimibe, commonly combined with statins for cholesterol lowering, blocks the NPC1L1 receptor in the gut that is responsible for absorbing both cholesterol and vitamin K, potentially creating a dual mechanism of vitamin K depletion. Research on warfarin (a vitamin K antagonist) shows significant negative impacts on bone mineral density, particularly in men, supporting the clinical importance of adequate vitamin K status. While solid clinical evidence linking statin and ezetimibe use to vitamin K deficiency outcomes remains limited, the mechanistic pathway is theoretically sound and warrants consideration. Dr. Bishop recommends that patients on lipid-lowering medications consider vitamin K supplementation to mitigate potential deficiency and support optimal bone health and calcium regulation.

EP354: Metabolic Syndrome Meeting

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Episode Summary Introduction Dr. Warwick Bishop, a cardiologist, author, and CEO of the Healthy Heart Network, hosts this episode to discuss cardiometabolic health—the intersection of heart disease, diabetes, fatty liver disease, and dementia. After addressing listener feedback about a previous episode on the nocebo effect, Dr. Bishop shares key insights from a cardiometabolic academy conference in Melbourne featuring presentations from leading experts in cardiology, lipids, nephrology, hepatology, and neurology. Key Takeaways: Type 1 and Type 2 diabetics carry essentially the same cardiovascular disease risk, contrary to the common assumption that Type 2 diabetics face greater risk. SGLT2 inhibitors (empagliflozin) and GLP-1 agonists (semaglutide/Ozempic) reduce cardiovascular events independently of their effects on glucose control and weight loss, suggesting distinct hormonal mechanisms at play. Prescribers must inform patients starting on SGLT2 inhibitors about rare but serious risks including diabetic ketoacidosis and Fournier's gangrene. Multiple weight loss medications are now available in Australia, with emerging agents like bimagrumab showing promise for weight loss without corresponding muscle mass loss. GLP-1 receptor agonists have receptors throughout the body (pancreas, heart, kidney, brain, stomach, liver), explaining their broad therapeutic effects beyond glucose management. Approximately 50% of people classified as "metabolically healthy overweight" develop diabetes within 10-15 years, challenging the concept of healthy obesity. Fatty liver disease affects roughly one in three people and serves as an early indicator of cardiometabolic disease progression, with early intervention through diet, exercise, and medication potentially preventing serious outcomes. Imaging advances now allow detection of inflammation in arteries and surrounding perivascular fat, which correlates with increased future cardiovascular event risk. GLP-1 agents may help reduce dementia progression by offsetting shared risk factors between Alzheimer's disease and vascular dementia. Read more

EP353: 6 Tips For Bone Health

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction Dr. Eric Bishop is a cardiologist, author, keynote speaker, and CEO of the Healthy Heart Network who is passionate about helping people live well for as long as possible. In this episode, he discusses osteoporosis prevention and bone health as we age, drawing on insights from a Lifeforce guide and sharing his personal interest in the topic through his OsteoStrong franchise. The episode focuses on six practical strategies for maintaining strong bones and muscle strength throughout life. Key Takeaways: Get enough calcium, vitamin D, and vitamin K2, which are essential building blocks for bone formation, similar to ingredients needed for baking a cake. Resistance and weight training are critical for stimulating bone growth and maintaining muscle strength, with OsteoStrong being an efficient method requiring only one visit per week. Limit processed foods and opt for whole foods without barcodes, as studies show processed meats, pastries, and pizza are linked to lower bone mineral density. Reduce alcohol consumption as it interferes with vitamin D metabolism and calcium absorption, and increases the risk of metabolic syndrome. Ensure adequate protein intake (approximately 2 grams per kilogram of body weight daily), as amino acids and proteins like collagen are essential for building and maintaining both bone and muscle as we age. Quit smoking, as cigarette smoke is detrimental not only to overall health but specifically damages bone health. Recognize that protein requirements increase with age due to reduced production, absorption, and exercise capacity, making protein supplements a sensible consideration for many older adults. Understand that bone and muscle loss are linked to frailty and poor long-term health outcomes, making prevention through proper nutrition and exercise a priority. Read more

EP352: Longevity Lounge with Doctor Warrick Bishop

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction Dr. Warwick Bishop, a renowned Australian cardiologist, best-selling author, and preventative medicine specialist, joins hosts Carl Treach and Guy Leach on the Longevity Lounge to discuss heart disease prevention. Dr. Bishop is the CEO of the Healthy Heart Network and is passionate about helping people understand how to live well for as long as possible, emphasizing that most heart attacks in Australia could be prevented with proper knowledge and screening. This highly anticipated episode focuses on preventative cardiology and actionable steps listeners can take to avoid future health crises. Key Takeaways: One in four Australians die from heart disease, and 20% of all heart attacks occur in people 65 years of age or younger, making early screening critical regardless of fitness level A reactive "tow truck mentality" to health is insufficient; preventative screening through advanced cardiac imaging like CT scans can identify hidden plaque buildup before a life-threatening event occurs Forty percent of all heart attacks occur in arteries that are not narrowed until plaque ruptures and forms a clot, meaning stress tests and feeling fine are not reliable indicators of cardiac health Men should ideally be screened for heart disease at age 50 and women at age 60, but those with risk factors like elevated cholesterol, pre-diabetes, or bad family history should be screened starting at age 40 and 50 respectively Even highly trained athletes and elite endurance competitors are not immune to heart disease; Emma Carney and Greg Welch are examples of world triathlon champions who required pacemakers despite peak fitness levels Atrial fibrillation can be linked to excessive endurance athletic training, as intense exercise can trigger inflammation that paradoxically increases arrhythmia risk despite exercise's overall anti-inflammatory benefits Cardiac CT imaging technology has advanced significantly since the early 2000s, allowing doctors to "lift the bonnet" and visualize the heart in detail to detect problems before symptoms appear A pivotal moment for Dr. Bishop came when he resuscitated a 53-year-old runner who had collapsed during a fun run, only to discover he had examined the same patient 18 months prior—prompting his shift toward preventative cardiology Read more

EP351: Talking Heart and Aging With Dr Luong Part 2

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. Podcast Summary Introduction: Warwick Bishop hosts Dr. Rebecca Loong, a qualified dietitian with a PhD in cardiometabolic health and accredited sports dietitian, for the second episode of their discussion series. This episode focuses on macronutrients—specifically fats and protein—and their role in promoting healthy aging, building on their previous conversation about carbohydrates and insulin in heart-healthy diets. Key Takeaways: Frailty and cardiovascular disease are closely interrelated, with frailty increasing the risk of major adverse cardiovascular events by 2-5 times and the risk of developing cardiovascular disease by about 2 times. A dietary pattern rich in vegetables, legumes, and seafood is associated with reduced prevalence of frailty across multiple research studies, both observational and longitudinal analyses. Older adults require higher protein intake than previously recommended, with current evidence suggesting 1.2 to 1.6 grams of protein per kilogram of body weight, compared to the older guideline of 0.9 grams per kilogram. Approximately 100 grams of cooked protein sources (fish, chicken, or beef) provides roughly 30 grams of protein, and protein intake should be distributed throughout the day across multiple meals rather than concentrated in one sitting. Protein comes from diverse food sources including meat alternatives, legumes, fish, nuts, seeds, eggs, and dairy products, making it easier to meet daily targets by incorporating protein at breakfast, lunch, and dinner. Whole foods are generally preferable to protein supplements because they provide additional vitamins and minerals alongside protein, though supplements can be useful when whole food intake is inadequate. Dairy consumption is particularly important for older adults, with recommended servings increasing from 2.5 serves to 3.5-4 serves daily to support both protein intake and calcium needs for bone health. Using practical tools like the fist measurement method or free apps like "Easy Diet Diary" can help people understand portion sizes and track protein intake without requiring long-term food tracking.
