I have over 20 years as a specialist cardiologist, a private practice of over 10,000 patients.
Australia, like the rest of the western world, has a heart problem.
Over 9 million people around the world die from heart disease every year.
Every 10 minutes, someone in Australia suffers a heart attack. And 21 lives are lost daily because of it.
The devastating fact in all this is…
Almost every one of those cases could have been prevented.
This podcast is for anyone who wants to improve their health literacy and gain information to help them make the best decisions about their risk of heart attack, their cholesterol, blood pressure, risk of diabetes, weight loss and general health. Join me on my personal mission journey to prevent Heart Attack on a global scale. If you like this podcast I would be honoured with a 5-star review and let your friends and family know, you may even save the life of someone you love!

EP313: The Brain and Low 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. This episode discusses a scientific statement from the American Heart Association on the impact of aggressive LDL cholesterol lowering on the risk of dementia and hemorrhagic stroke. The statement finds that lowering LDL cholesterol reduces the risk of cardiovascular disease and does not increase the risks of dementia or hemorrhagic stroke. While some older studies suggested potential cognitive effects, larger and randomized studies do not support this. The risk of hemorrhagic stroke is also small and nonsignificant for those without a history of cerebrovascular disease. The statement concludes that concerns about these risks should not prevent clinicians from treating patients to the recommended LDL cholesterol targets. Read more
EP312: QLD Lipid Meeting October 2023
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. This episode discusses presentations from the annual Queensland lipid group meeting. Professor Derek Connelly spoke about overcoming inertia in cholesterol lowering. A new drug called Inclisiran was discussed, which reduces LDL cholesterol through the PCSK9 protein system and only requires dosing every 6 months. Karam Kostner presented on lipoprotein(a), an emerging risk factor for cardiovascular disease. Professor David Cahun emphasized the importance of measuring the omega-3 index through a blood test. Talks addressed inflammation and how diet and certain drugs may help reduce it. Imaging techniques are blurring the line between primary and secondary prevention by finding plaque in asymptomatic patients. Coronary calcium scoring provided insights into risk assessment. The meeting covered various topics around optimizing cardiovascular health and risk reduction. Read more

EP311: Fat Bellies and Skinny Brains
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. This episode discusses a study finding that both visceral and subcutaneous abdominal fat are linked to lower brain volume in middle-aged adults. Visceral fat around the organs and subcutaneous fat under the skin were associated with brain atrophy on MRI scans, especially in women. Excess abdominal fat was found to predict reductions in total gray and white matter as well as specific brain regions. While the effects were small for individuals, trends emerged across large samples. Lifestyle factors like physical activity and diet were not fully accounted for. The research suggests abdominal fat may help explain previously reported connections between obesity and cognitive decline. Read more
EP310: Common Cardiac Drugs and Common Interactions
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. The episode discusses common cardiac drugs and some potential drug interactions. It covers aspirin, warfarin, clopidogrel, proton pump inhibitors, beta blockers, ACE inhibitors, digoxin, nitrates, and amiodarone. Notably, grapefruit can increase serum levels of beta blockers, calcium channel blockers, and some statins, potentially leading to toxicity. Warfarin's effects can be altered by foods high in vitamin K like leafy greens. Clopidogrel's effectiveness may be reduced when taken with proton pump inhibitors like omeprazole. Combining nitrates with phosphodiesterase inhibitors like sildenafil can cause profound blood pressure drops. The host recommends being aware of possible drug interactions and maintaining regular communication with doctors. Read more

EP309: 10 Commandments of Heart Health Explained
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. This episode discusses 10 commandments for heart health, including not smoking, regular exercise, healthy eating, limiting alcohol, controlling blood pressure and weight, managing diabetes and cholesterol, understanding heart medications, and building a support system. It recommends getting a heart scan to precisely determine cardiovascular risk beyond standard risk calculators. An interesting finding mentioned is that a study on the artificial sweetener aspartame showed it could increase anxiety levels even in subsequent generations of mice not directly exposed. Read more
EP308: Myocardial Bridging—a Bridge Too Far
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. Doctor Warrick Bishop discusses heart disease risks and prevention on his podcast. He talks about an interesting presentation he saw on myocardial bridging, where the coronary artery runs through the heart muscle in 20% of people. This was thought to not impact blood flow, but can in rare cases limit flow and cause angina symptoms. This is a cause of MINOCA syndrome, where ischemia occurs despite clear arteries. Doctor Bishop describes diagnostic tests like CT scans and intravascular ultrasound to identify bridging arteries. Surgery called deroofing can be done to free up a compressed artery. Medications may also help symptoms but stents are unlikely to. The podcast highlights this potential new cause of angina symptoms from a rare arterial variation. Read more
EP307: Long QT, Blood Pressure and Pregnancy
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. Doctor Warrick Bishop discusses various topics from a cardiology conference, including long QT syndrome and how stress testing can help evaluate it. He highlights that only 32% of patients with high blood pressure have it adequately controlled. Doctor Bishop also notes the complexities of managing pregnant patients with mechanical heart valves, as anticoagulation treatment needs careful monitoring. The podcast provides insights from medical experts on important cardiovascular issues like blood pressure management and risks during pregnancy, helping listeners understand heart health. Read more

EP306: Inflammation, White Cells, Stroke and Salt
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. Doctor Warrick Bishop discusses various topics related to heart health and inflammation in this podcast. He talks about a study that found intensive periodontal treatment reduced blood pressure by 5-10 mmHg by reducing inflammation. Another interesting finding was that rats who experienced a stroke showed changes in their gut microbiome and increased gut permeability, leading to systemic infection. Doctor Bishop also discusses how a high-salt diet can directly damage the gut microbiome and allow inflammatory proteins to enter the bloodstream, triggering inflammation in blood vessels even before high blood pressure occurs. He recommends keeping salt intake low, staying hydrated, and consuming fiber to help protect the gut from these salt-related harms. Read more
EP305: Syncope CSANZ 2023
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. The episode discusses different causes of non-traumatic loss of consciousness or syncope, including cardiac, epileptic, and psychogenic reasons. Cardiac causes could be things like structural heart issues, arrhythmia, or orthostatic hypotension from standing up. Doctor Warrick highlights how an epileptic seizure may involve jerking at the onset of loss of consciousness unlike cardiac syncope. Taking a thorough history from witnesses is important to determine the likely cause. One interesting point was how tongue biting on the sides suggests epilepsy while biting the tip suggests falling during cardiac syncope. Distinguishing the etiology helps guide appropriate workup and management. Read more
