Dr. Sara Gottfried strongly recommends a Coronary Artery Calcium (CAC) score, a CT scan of the chest, for all women by age 45. This simple, self-orderable test provides a critical assessment of cardiometabolic health, enabling early, personalized intervention for heart disease risk.

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.

HDL cholesterol, typically seen as protective, can become dysfunctional in the presence of risk factors like smoking or obesity. This dysfunctional HDL then contributes to atherosclerosis instead of preventing it, challenging the simplistic 'good vs. bad' cholesterol narrative.

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.

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.

Focusing solely on LDL is a mistake. Even individuals with a genetic mutation leading to lifelong low LDL levels can still have cardiovascular events if they have other unmanaged risk factors like metabolic syndrome, obesity, or diabetes, highlighting the need for a comprehensive approach.

Relying on blood lipid panels (LDL, etc.) to assess cardiovascular risk is misleading, as they don't confirm arterial plaque. A CT angiography (CCTA), like a Cleerly scan, provides direct imaging of both hard and soft plaque, offering a far more accurate assessment of actual heart disease risk.

The silent nature of high cholesterol creates a psychological barrier. Patients who feel perfectly healthy are often unwilling to commit to lifelong treatment, even when their risk is high, leading to preventable cardiovascular events.

Medical lab test ranges define 'normal' by the average of the current population. In a society where 75% are overweight, this standard is not optimal. This creates a false sense of security, as being 'normal' might still mean being on a trajectory toward chronic disease.
