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

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

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
