EP30: How Rapid Heartbeat (Arrythmia) Can Damage The Heart

Today, I'd like to speak with you a little bit about a concept that we call tachycardia-induced cardiomyopathy. That's a mouthful, so let me break it down for you. "Tachy" means fast. "Tachycardia", "cardia" relates to heart, so fast heart. Induced means the same whether it's referring to the medical term or common vernacular. "Cardia", referring to the heart, and myopathy referring to a problem with the muscle. So, fast heart-induced muscle problem, or Tachycardia-induced cardiomyopathy. Read more

EP29: Do I Need A Pacemaker For Atrial Fibrillation?

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 Dr. Warwick Bishop, a practicing cardiologist and author, hosts this educational podcast aimed at helping patients understand their heart health. In this episode, Dr. Bishop addresses a frequently asked question from his atrial fibrillation patients: whether they need a pacemaker. The episode explains the fundamental difference between atrial fibrillation and the conditions that actually require pacemakers. Key Takeaways: Pacemakers are designed to treat slow heart rates by providing electrical stimulation, not to address rapid heartbeats. The general answer to whether atrial fibrillation patients need a pacemaker is no, since AF causes the heart to beat too fast, not too slow. Atrial fibrillation occurs when the atria beat rapidly and chaotically, flooding the AV node (the electrical gateway between the upper and lower heart chambers) with impulses. These excessive electrical impulses from the chaotic atria drive the ventricles into rapid, irregular contractions, characteristic of atrial fibrillation. Atrial fibrillation requires heart rate regulation rather than pacemaker therapy. In rare cases, when medications fail to adequately control atrial fibrillation or aren't well tolerated, doctors may perform AV node ablation to completely disconnect the atria from the ventricles. When AV node ablation is performed for atrial fibrillation, a pacemaker must be implanted simultaneously because this procedure would otherwise leave the heart beating dangerously slowly. Dr. Bishop emphasizes that patient education leads to better healthcare outcomes. Read more

EP28: Unexpected Positive Effects On Anticoagulation

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 Dr. Warwick Bishop, a practicing cardiologist and author, discusses anticoagulant medications used to treat atrial fibrillation. While these blood thinners are primarily prescribed to reduce stroke risk by preventing clot formation in the heart, Dr. Bishop explores some unexpected positive side effects that patients and doctors should be aware of beyond their primary cardiovascular benefits. Key Takeaways: Anticoagulants like warfarin and NOACs (non-vitamin K oral anticoagulants) are prescribed for atrial fibrillation to reduce stroke risk by preventing clots in the left atrial appendage of the heart. Blood thinners carry known risks including increased bleeding, particularly hemorrhagic stroke and gastrointestinal bleeding from existing lesions. Anticoagulants provide a secondary benefit for patients traveling long distances by also preventing deep vein thrombosis (blood clots in the legs) and pulmonary embolism. Increased bleeding from anticoagulants can paradoxically lead to earlier detection of bowel cancer by making fecal occult blood tests more likely to be positive when early tumors are present. Dr. Bishop has observed patients in his own practice having bowel cancer detected early due to positive fecal occult blood tests while on anticoagulants. When starting anticoagulation therapy, patients should consult with their GP about whether they are due for fecal occult blood screening to take advantage of this detection benefit. There is a potential future application of combining short-term anticoagulant therapy with routine fecal occult blood testing to increase screening sensitivity, though this remains untested.

EP27: Blood Sugar And Testing

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. EP27: Blood Sugar And Testing - Summary Dr. Warwick Bishop is a practicing cardiologist and author dedicated to educating patients about heart health and cardiovascular care. In this episode, he discusses a patient case involving blood sugar assessment and explores the limitations of standard glucose tolerance testing. Dr. Bishop explains why measuring insulin resistance through the HOMA index may be a more effective diagnostic approach for identifying cardiovascular risk factors in certain patients. Key Takeaways: Standard glucose tolerance tests may miss insulin resistance because they only measure blood sugar at fasting and two hours post-glucose load, missing the metabolic activity that occurs in between. A patient can have a "normal" glucose tolerance test result while still showing signs of insulin resistance, including elevated fasting glucose, elevated triglycerides, low HDL cholesterol, and central weight gain. The HOMA (Homeostatic Metabolic Assessment) index uses simultaneous fasting blood sugar and insulin measurements to calculate an index that indicates whether a patient is insulin resistant. High HOMA index values (elevated insulin with slightly elevated or normal blood sugar) indicate insulin resistance, meaning the body requires excessive insulin to control blood sugar levels. Insulin resistance is strongly linked to cardiovascular risk factors including elevated triglycerides, reduced HDL cholesterol, and central obesity. Patients with insulin resistance benefit significantly from reducing carbohydrate consumption, which can lower insulin response, promote weight loss, reduce triglycerides, and improve HDL levels. HOMA testing may be a more appropriate initial assessment than glucose tolerance testing for patients showing metabolic syndrome characteristics, even if their fasting glucose isn't high enough to indicate diabetes.

EP23: Changing Terminology

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 Dr. Warwick Bishop is a practicing cardiologist and author dedicated to improving patient care through heart health education. In this episode, he discusses the critical importance of accurate medical terminology in cardiac reporting, specifically addressing how the language used to describe plaque buildup in arteries can have significant consequences for patients in a primary prevention setting (those who haven't yet experienced cardiac events). Key Takeaways: Primary prevention focuses on reducing risk in asymptomatic patients who have not yet experienced a heart event, while secondary prevention aims to prevent recurrence in patients who have already experienced cardiac symptoms or events. A disease, by definition, requires either a symptom or loss of function; asymptomatic patients with plaque buildup technically do not have a disease yet. Current medical practice often labels any arterial plaque as "coronary artery disease" regardless of whether the patient is in a primary or secondary prevention setting, which inappropriately blurs the distinction between these two categories. Labeling asymptomatic patients with "coronary artery disease" can cause significant emotional and psychological distress to proactive patients who feel perfectly well. Insurance disclosure requirements mean that a coronary artery disease diagnosis can result in future insurance denial, even when only minimal plaque buildup is detected. Patients requiring professional licensing (such as commercial pilots) may face serious career consequences if diagnosed with coronary artery disease, even if they are fit, active, and on appropriate medication. Dr. Bishop advocates for using the term "atheroma burden" instead of "disease" when describing plaque buildup in primary prevention patients to avoid unnecessary stigmatization and practical complications. Changing terminology requires professional consensus and awareness among cardiologists to ensure consistent, patient-centered reporting practices. Read more
