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

Introduction: Dr. Warwick Bishop is a practicing cardiologist and author who advocates for patient education in heart health. In this episode, he discusses an extraordinary letter from a colleague cardiologist that exemplifies why he created the Healthy Heart Network and promotes cardiac CT imaging technology. The letter reveals concerning clinical judgment about managing a 50-year-old patient with elevated cholesterol, which Dr. Bishop uses to highlight important gaps in modern cardiac risk assessment.

Key Takeaways:

• Cardiac CT imaging can reveal that outwardly healthy people may have unhealthy arteries, and conversely, people who appear at high risk may have surprisingly healthy coronary arteries—making it a valuable tool for accurate risk assessment.

• The cardiologist's dismissal of cardiac CT for a 50-year-old with intermediate risk (approximately 10% risk of event in 10 years) contradicts current Heart Foundation of Australia guidelines, which support cardiac CT imaging for intermediate-risk patients.

• A normal ECG does not indicate healthy coronary arteries; the two are separate systems, and assuming a normal ECG means no heart disease risk is medically inaccurate and potentially dangerous.

• Using cholesterol levels alone to predict cardiac risk is insufficient; comprehensive imaging allows doctors to identify actual plaque burden and tailor prevention strategies with greater precision.

• Prescribing medication with a "take it or leave it" approach represents poor medical practice and a lack of genuine concern for the individual patient's wellbeing and treatment outcomes.

• Cardiac CT imaging is cost-effective at $300-$660 compared to the potential devastation of a preventable heart attack, making the financial objection in the letter irrational.

• Risk-enhancers like elevated cholesterol should trigger further investigation in apparently healthy patients, not dismissal of diagnostic testing.

• Many healthcare professionals lack awareness of or resistance to newer technologies like cardiac CT that could significantly improve patient outcomes in cardiac risk stratification.
