New Cholesterol Guidelines Just Dropped. I'm 37 and Actually Paying Attention.

I was 13 when my grandfather died of a massive heart attack. The kind that doesn't give you a warning, doesn't give you time. One of those moments that rewires something in you — not in a way you can explain at 13, but in a way you carry forward every time the word "cardiology" comes up.

I'm 37 now, which still feels young until you start doing the math.

The American College of Cardiology and the American Heart Association just released their first updated cholesterol guidelines since 2018, and a few things stopped me. Screening is now recommended starting at 19(!). Risk assessment begins at 30, and it now calculates your 30-year risk, not just 10, which changes the conversation entirely when you're sitting across from a doctor who thinks you're "too young to worry." For people with a family history, earlier medication is on the table. And there's a new test most of us have never heard of: Lp(a), or lipoprotein(a), recommended once in every adult's lifetime. It's mostly genetic, highly predictive, and almost never brought up unless you ask.

That last part is the one that gets me. About 1 in 4 adults has elevated LDL cholesterol, and most don't know it. Heart disease is still the number one killer of women, accounting for roughly 1 in every 5 female deaths. And yet the default is still to wait, to monitor, to revisit it later.

My grandfather didn't get later. So the next time I'm at my doctor, I'm asking for the Lp(a) test, and I'm not apologizing for it.
