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

EP304: Grip Strength and Chocolate Follow-up

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 grip strength as an indicator of overall health, with weaker grip linked to various illnesses. Data from the Swedish army found men with weaker grips were 20% more likely to die by age 55. Exercises like weightlifting can strengthen grip indirectly. The host also updates on heavy metals in chocolate, noting some studies found links to lower bone density but chocolate has antioxidants too. Listeners provided more data, suggesting raw cacao may be healthier than dark chocolate. In summary, grip strength and chocolate content were insightful topics covered to help listeners improve their health. Read more

EP303: Take Homes From ESC August 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 several studies presented at the European Society of Cardiology Congress, including one finding that completely opening blocked arteries in older heart attack patients led to better outcomes. Another study surprisingly showed iron infusion did not help heart failure patients as expected. The episode also mentions that ablation seems to be more effective for atrial fibrillation in advanced heart failure cases. Managing weight through drugs like Ozempic was found to benefit those with heart failure and preserved ejection fraction as well. Throughout, Doctor Warrick emphasizes the importance of a multi-disciplinary approach to genetic heart conditions. Read more

EP302: Discussing Low Carb and Keto and CAD with Doctor Kostner and Doctor Sangster

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 reduced carbohydrate diets and their effects on cardiovascular health. While such diets may help with weight control and blood sugar levels, there is debate around their long-term safety, especially for those with heart disease or diabetes. Saturated fat intake is known to raise LDL cholesterol, which can increase heart risks. However, monounsaturated fats may be more favorable. The experts discuss how individual responses to diet and cholesterol-lowering medications can vary greatly. They agree these diets can be appropriate for healthy people without heart conditions, but more research is still needed on long-term outcomes. The potential benefits must be weighed against risks for each individual patient. Read more

EP301: Discussing Bad cholesterol and CAD Dr Kostner and Dr Sangster

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 LDL cholesterol and its link to coronary artery disease. While LDL is generally considered a risk factor, it may not predict outcomes for every individual. Different types of LDL particles can vary in their risks, with smaller, denser particles posing more issues. Triglyceride levels were also noted as important. Guest Doctor Sangster shared how investigating particle size led to insights. Lowering LDL through diet, statins, or other means seemed to provide benefits to those with demonstrated artery problems.

EP300: Dangers of Obstructive Sleep Apnoea

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. Obstructive sleep apnea (OSA) is a common condition where the muscles in the throat relax during sleep, causing partial or complete airway blockage. Risk factors include obesity, age, family history, and being male. Symptoms include loud snoring, gasping, and excessive daytime sleepiness. Left untreated, OSA can increase risks of high blood pressure, heart disease, diabetes, and vehicle accidents. Diagnosis involves an overnight sleep test to measure breathing disruptions. Weight loss and lifestyle changes can help mild cases. Treatment often involves using a CPAP machine, which blows air to keep the airway open during sleep and reduces daytime sleepiness by 70%. This episode highlights how undiagnosed OSA in truck drivers increases safety risks on the road. Read more

EP299: CSANZ 23 - Athletes and SCA

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 various topics in sports cardiology and cardiac health. It explores the potential link between endurance exercise and atrial fibrillation in athletes. It also notes that exercise is generally good for heart health but may be associated with increased calcium buildup in arteries for long-distance runners. The episode covers genetic testing for cardiac conditions in athletes and reviews causes of sudden cardiac death in young people, finding that coronary artery disease is a leading cause. It highlights the importance of identifying people with familial hypercholesterolemia to reduce cardiac risks. Read more

EP298: Blue Light Glasses and Smells to Remember

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 the risks of heart disease and introduces his podcast aimed at helping listeners understand factors like blood pressure, weight, and cholesterol. He reads an article questioning the effectiveness of blue light glasses, noting that screens expose us to only a tiny fraction of blue light compared to daylight and glasses filter only 10-25% of that. The episode also covers a study finding that inhaling pleasant scents during sleep was linked to dramatically improved memory and brain activity, with those exposed to essential oils experiencing a 226% boost in memory performance. This preliminary research suggests the olfactory system may directly impact memory centers in the brain. Read more

EP297: Treating Kids Cholesterol and Testosterone 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. Dr. Warrick Bishop discusses two important health stories in the podcast. First, he disagrees with a US task force recommendation against screening children for high cholesterol, citing evidence that early treatment can help those with a genetic condition called familial hypercholesterolemia. Second, he outlines findings from a large trial showing that testosterone therapy for men aged 45-80 does not increase risks of heart issues or prostate cancer. However, it may slightly raise risks of atrial fibrillation, kidney injury, and pulmonary embolism. Interestingly, it also seemed to increase fracture risk, possibly because the men felt better and became more physically active. Read more

EP296: Ingredients to Happiness & Screening Cancers

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. Dr. Warrick Bishop hosts a podcast about health and wellness. He discusses findings from the Harvard Study of Adult Development, which found that close relationships and good health were the two major factors for happiness. Strong relationships were actually a better predictor of good health outcomes than other factors like career success. The study also showed that happiness fluctuates and loneliness can be problematic if one does not have close relationships. Dr. Bishop then talks about research on detecting cancers like colorectal cancer through blood tests by finding abnormal DNA and RNA fragments in the bloodstream. He highlights that non-invasive blood tests for cancer may soon replace colonoscopies. In closing, Dr. Bishop encourages living well and building relationships for a happy life. Read more
