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, a cardiologist and CEO of the Healthy Heart Network, discusses the importance of understanding cholesterol in his podcast. He explains that cholesterol is crucial for cell membranes, hormone formation, and vitamin transport, and that LDL and HDL are transport vehicles for cholesterol. Dr. Bishop clarifies that cholesterol's impact on heart health is complex, as high LDL doesn't always indicate artery plaque, and low cholesterol doesn't always mean healthy arteries. He emphasizes the importance of coronary artery calcium scoring, particle numbers, and other factors in assessing artery health and predicting risk. For secondary prevention, lowering cholesterol is crucial, while primary prevention requires a personalized approach, considering individual risk factors and imaging.
