Medicare Will Pay $50k for Your Heart Attack. It Should Pay $100 to Prevent It

Coronary artery disease is often detectable years before a heart attack, but prevention has relied heavily on risk calculators based on factors such as age, cholesterol, blood pressure, and smoking. The authors argue that these estimates can miss existing disease: a coronary artery calcium (CAC) scan directly measures calcified plaque, takes about 10 minutes, costs roughly $100, and uses relatively little radiation. Updated ACC/AHA guidelines issued in March 2026 recommend the scan for people at borderline or intermediate risk when it remains unclear whether to begin preventive treatment. A score of zero can support avoiding unnecessary medication, while a score above 100 can indicate a need for treatment and stronger lifestyle measures. One example is a healthy 52-year-old man whose conventional risk estimate was low but whose CAC score of 220 revealed substantial plaque and changed the case for drug therapy.

The central criticism is that healthcare systems spend heavily treating heart attacks - about $50,000 in the title’s comparison - while often failing to pay for inexpensive ways to prevent them. Despite decades of evidence, CAC remained marginal in guidelines and inaccessible to many patients because clinical tools favor population-level risk factors, providers face cautious practice norms, and insurers often do not cover scans. The authors see the new guidance as a shift toward measuring disease itself. They also argue that AI could find calcium in chest CT scans already taken for other reasons, flagging people for follow-up, and may eventually identify soft plaque. Used responsibly, these approaches could extend prevention beyond patients able to pay out of pocket.
