Episode 5 – The Decision: When a CAC Score of 18 Stopped Being Just a Number

Coronary CT scan showing mild calcified plaque in the LAD (CAC score: 18)

For the full arc of this experiment, I recommend reading the series sequentially from Episode1 through Episode 5. The story unfolds cumulatively — much like biology itself.

Episode 4 – An Engineer’s Dilemma: Should I Debug My LDL or Just Take the Statin? 

Episode 3 – When Numbers Tell Stories: My Annual Blood Report Meets Twice a Month Fasting 

Episode 2 – When Fasting Met Blood Donation — An Accidental Experiment 

Episode 1 – A Journey to Outsmart Blood Sugar (Before It Outsmarts Me) 

By now, the numbers are no longer abstract. They have names, units, and an unsettling tendency to show up in places I’d rather not look.

      ApoB: 124 mg/dL

      CAC score: 18

Not catastrophic. Not zero.

Just enough to end denial. Not enough to qualify for a dramatic hospital montage — but sufficient to make arrogance feel slightly irresponsible.

The Real Question

My metabolism is good. Triglycerides low. Insulin sensitive. Blood pressure fine.

And yet — plaque.

The lesson is uncomfortable but simple:

You can be metabolically disciplined and still be particle-heavy.

ApoB does not respond dramatically to virtue. It turns out the liver does not award moral points for clean eating and optimism.

The 2% Reality

A low-dose statin in my case likely reduces absolute 10-year risk by about 2% (If you do not believe this percentage then write to me in the comment - I will share with you the engineering calculation to satisfy your biological curiosity)

Not dramatic.
Not trivial.

This is what prevention actually looks like — incremental, statistical, and deeply uncinematic. No swelling music. Just spreadsheets.

---

The Plan (No Drama)

Phase 1: Finish 12 weeks of Vitamin D correction.
Phase 2: Recheck ApoB.
Phase 3: Start low-dose statin for 6 months.
Phase 4: Stop for 3 months. Recheck ApoB.

Then decide — preferably without pretending the outcome will surprise me.

If ApoB rebounds above ~110 → long-term statin makes sense.
If it stays below ~95 → lifestyle carries more weight.

No guesswork. Just measurement. Because denial, while emotionally efficient, is biologically expensive.

The Line I am Drawing

ApoB was the signal.

CAC was the confirmation.

Formal Coronary Artery Calcium (Agatston) report confirmingtotal score of 18

The report above is real. Eighteen is small — but it isn’t zero. And zero, I’ve learned, is a very comforting fantasy.

I’m not afraid of a statin. I’m more suspicious of pretending the numbers will age gracefully on their own.

If my ApoB stays stubborn, I’ll choose maintenance over mythology. If it behaves, I’ll accept that — without writing a self-help book about it.

No heroics. No denial.

Just fewer illusions — and less calcium where it doesn’t belong. Not destiny. Not doom. Just accumulated exposure quietly keeping score and data deciding the next decade.

⚠️ Author's Note

These reflections come from an engineer who started learning human biology far too late in life — mostly out of curiosity, partly out of necessity. What began as an attempt to outsmart blood sugar turned into a crash course in metabolism, ratios, and resilience. I’m not a doctor, and this isn’t medical advice. Please consult your physician before experimenting with fasting, diet tweaks, or supplement changes. Think of this as a mid-life engineering project on the body’s operating system — one where trial, error, and humility are all part of the lab work.
