Episode notes
Plaque Hides In Vessel Walls
- Plaque builds in the vessel wall and expands outward long before it narrows the lumen.
- Stress tests and early symptoms miss decades of disease because symptoms appear only after ~70% lumen narrowing.
Prefer Cardiac CT Over Stress Tests
- Stop relying on stress tests and invasive caths as first-line screening for coronary plaque.
- Use cardiac CT when you want an early, accurate picture of coronary plaque before symptoms appear.
Cardiac CT Is A Virtual Autopsy
- Modern cardiac CT produces ultra-high resolution 3D images with very low radiation.
- It functions as a 'virtual autopsy' that reveals valves, function and coronary plaque in one scan.
