Standard cholesterol tests are poor predictors of heart attacks, as 50% of victims fall within the 'normal' range. This reliance on an incomplete metric means millions of people, including those with healthy lifestyles, may have a false sense of security about their heart health, overlooking the more definitive presence of arterial plaque.
Decades ago, a legislative battle pitted preventative technology (calcium CT scanners) against treatment solutions (stents). The stent lobby won, shaping medical standards to favor profitable, reactive procedures over inexpensive, proactive screening. This regulatory capture explains why cholesterol remains the primary marker despite its flaws, hindering widespread adoption of more effective preventative tools.
Top preventative cardiologists privately advise their own families to get a CAC scan at age 30-35. If the score is non-zero, they prescribe statins to get LDL cholesterol below 40—less than half the standard 'green zone' level. This reveals a significant gap between public guidelines and the aggressive preventative strategies used by experts for their loved ones.
Highly athletic individuals can inadvertently train their hearts to compensate for underlying disease, causing them to pass stress tests and EKGs while still at high risk. This was the case for Dave Goldberg, who passed a running EKG five months before dying from undiagnosed heart disease. It highlights a critical flaw in relying on performance-based tests for cardiac screening in fit populations.
A pragmatic approach to heart screening is to use the cheap, non-invasive Calcium CT (CAC) scan as a first-line filter. If the result is zero, further testing may be unnecessary. A non-zero score, indicating a propensity to build plaque, then justifies the more invasive and expensive ($2,000+) angiogram to assess soft plaques and blockage levels. This tiered strategy makes advanced screening accessible and cost-effective.
A mobile CT scanner is being brought to Silicon Valley companies, which pay double the cost per scan for their employees. This extra revenue funds free scans in underserved communities like East Palo Alto. This innovative 'buy one, give one' model transforms a corporate wellness perk into a vehicle for addressing health equity, creating a scalable and self-funding public health program.
