The $100 Test That Could Save 50,000 Lives a Year

Half of the people who have heart attacks every year have cholesterol in the normal zone. That single statistic is at the center of Brad Gerstner's argument that the standard of care for heart health in the United States is dangerously inadequate. Gerstner, speaking at the All-In Summit alongside Rob Goldberg, is standing in front of a mobile calcium CT scanner he bought a year ago—a trailer that has already produced scores that "most definitely have saved people's lives" over the course of two days at the summit.

The Failure of Cholesterol as a Screening Tool

The current standard of care relies on cholesterol testing. Patients get their numbers, see they're in the "green zone" between 80 and 120, and feel reassured. Gerstner himself was in the green zone at 100. But cholesterol alone misses the real problem. "Half of the people who have heart attacks every year have cholesterol in the normal zone," Gerstner says. The mechanism works like this: a calcium CT scan detects whether you have calcified plaque in your arteries—the precursor to the blockages that cause heart attacks. You cannot have a heart attack without plaque. Cholesterol is merely the agent that carries plaque to the arteries, but if you don't know whether you have plaque in the first place, knowing your cholesterol level is insufficient.

Show Notes

Brad Gerstner & Jason Chang are trying to turn the $100 CAC heart scan into the “mammogram for the heart.”At the All-In Summit, Brad and Jason brought his mobile coronary artery calcium CT scanner to screen attendees & make the case for preventing heart attacks at scale.Heart disease kills ~800,000 Americans annually. Brad and Jason believe scaling CAC scans to 40M people a year could save 50,000 lives and $20B in government healthcare costs annually.Rob Goldberg joined us to explain why the mission is deeply personal.His brother Dave Goldberg, married to Sheryl Sandberg, died suddenly at 47 from undiagnosed heart disease, leaving behind their two young children. Just five months earlier, he had passed a running EKG.“My brother had passed a running EKG five months before he dropped dead from heart disease, from undiagnosed heart disease.”Dave’s death became the foundation for Sandberg’s book Option B, co-written with Adam Grant, about grief, resilience and rebuilding life after devastating loss.Now Rob Goldberg, Brad Gerstner, Jason Chang, & the rest of the besties, & the team behind the Center for Heart Attack Prevention want to prevent more families from experiencing the same thing, pushing for earlier detection, broader access to CAC scans & changes to the standard of care.We go inside the mobile scanner and discuss:› Why Brad calls CAC scanning the “mammogram for the heart”› The Goldberg family’s experience with undiagnosed heart disease› Why cholesterol & traditional testing can miss cardiovascular risk› What CAC scores actually tell you› Difference between a calcium CT scan & an angiogram› Why Brad bought his own mobile scanner› The “buy one, give one” model for expanding access› Brad’s push to bring CAC screening to 40 million Americans a year› How a roughly $100 scan could potentially prevent thousands of premature deaths› Why Brad believes health data gives people the power to take actionMolly on X: https://x.com/MollySOSheaBrad Gerstner on X: https://x.com/altcapJason Chang on X: https://x.com/yoweichangBrought to you by:Brex—The modern finance platform, combining the world’s smartest corporate card with integrated expense management, banking, bill pay, and travel.
