EP115: Misunderstanding, Misinterpretation, Mismanagement, and Misfortune
Description
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.
Podcast Summary
Dr. Warrick Bishop is a practicing cardiologist and author dedicated to patient education about heart health. In this episode, he discusses a real case involving a patient named Trevor, a 69-year-old man whose shortness of breath led to cardiac imaging that revealed high-risk coronary artery disease features. The episode illustrates how misinterpretation of imaging results and poor communication between healthcare providers can lead to dangerous undertreatment.
Key Takeaways:
-
Treadmill stress tests are functional tests that show how well the heart works under stress, but they don't reveal the anatomical condition of arteries or plaque buildup.
-
CT scans provide anatomical detail about coronary artery health and can reveal both calcified plaque and soft (non-calcific) plaque that may not be apparent from calcium scores alone.
-
A low calcium score doesn't guarantee low risk—some patients have significant soft plaque without much calcium, which can be equally or more dangerous.
-
The C-plus algorithm combines multiple factors (calcium score, plaque burden, plaque characteristics, remodeling, and stenosis) to provide a comprehensive risk assessment that goes beyond calcium score alone.
-
Trevor had a calcium score in the 20th percentile (seemingly low-risk) but actually had very high-risk features including substantial soft plaque and stenosis, with greater than 50% risk of heart attack in the next decade.
-
Patient misunderstanding of test results, combined with casual reassurance from a GP unfamiliar with complex imaging interpretation, led Trevor to stop taking prescribed high-intensity cholesterol medication.
-
Specialists and GPs must communicate directly with patients about medication changes rather than relying on patients to self-interpret test results or make independent decisions.
-
When medication causes side effects, patients should work with their specialist to find the maximum tolerable dose rather than stopping treatment entirely without medical guidance.
-
Patients should always return to their prescribing specialist before making changes to recommended treatment plans, even if seeking a second opinion from their GP.
-
Effective cardiac risk management requires collaborative communication between patient, GP, and specialist to ensure proper understanding and adherence to potentially life-saving therapies.
