Hosts say ‘normal’ cholesterol cut-offs once missed most heart-attack risk

What was said

"In the 1940s, 95% of the US population had blood cholesterol below 280. We know today that yeah, that heart attacks occur with levels much lower than that. In fact, most occur between 200 and 280."

Erin Welsh argues that older reference-range thinking (using a 95th percentile cut-off) led clinicians to treat total cholesterol values around 250 as ‘normal’ in mid-20th-century America. She says heart attacks often occur at total cholesterol levels below those historical thresholds, citing a 200–280 range.
