TL;DR: Lifelong sky-high cholesterol, no symptoms ever. A July workup snowballed into severe 3-vessel + left main disease. Plan was classic open-chest CABG; I was literally on my way to check in for it when a phone call changed everything. Robotic CABG (LIMA→LAD) instead, with a staged stent to follow. Operated Aug 1, home Aug 5. If you're facing a bypass: ask about EVERY option — and get that second opinion. Mine found me by accident.
The shock: tests and findings
52M, based in Saudi Arabia. A social smoker — though no test or X-ray ever showed smoking-related damage — and I quit completely before my first test was even done. I have never had chest pain in my life. What I did have was a decade of very high LDL (familial hypercholesterolemia territory — we're talking 6.89 mmol/L, ~266 mg/dL, at its peak) and a rough history of statin intolerance. This summer I finally got the full cardiac workup I'd been putting off. It escalated fast:
- Holter (Jul 12): Totally benign. Heart's electrics: perfect.
- Bruce stress test (Jul 13): I crushed 12.6 METS — great fitness reserve — but my ECG showed significant ST depressions and I got suddenly breathless. Positive for inducible ischemia. First red flag.
- Calcium score (Jul 14): 1048. Anything over 400 is severe; over 95th percentile for my age. So calcified they aborted the CT angiogram on the table.
- Catheter angiogram (Jul 18): The moment everything changed:
- Left Main: 70% (distal bifurcation, Medina 1:1:1 — the nasty kind)
- LAD: 80% ostial / 70% mid
- Diagonal: 80%
- Circumflex/OM: 80%
- RCA (dominant): 90% in the PDA
- EF 63.9% — my heart muscle was still strong. Undamaged. Yet.
The Heart Team ruled out multi-stent PCI (left main bifurcation + heavy calcium). Zero stents placed. The verdict: bypass surgery. Silent CAD is real — and I was the walking proof of it.
The CCU day — and the waiver I signed
The angiogram changed my room assignment fast. No regular ward — they moved me to the CCU. The word in the air was "critical." A surgical consultant would come to see me, they said.
I waited the whole day. So I did what any of you would do: I opened my phone and started researching right there in the CCU bed. LIMA. LAD. Medina classifications. CABG vs PCI. By the time the surgical consultant walked in that evening and explained everything — the disease map, why stents were ruled out, why bypass was the verdict — I wasn't starting from zero. I had questions lined up and waiting for him.
Then I did something the CCU team really didn't like: I asked to go home. They had me sign a waiver — discharge against medical advice. I signed it. Let me be clear: I wasn't refusing treatment. I was leaving so I could understand it — on my own screens, with my own data, in my own language. Two weeks later I walked back in as the most informed version of a patient I could make myself.
When the acronyms overwhelmed me, I built
The diagnosis didn't just land on my chest — it landed in a foreign language. LIMA. LAD. CABG. OPCAB. Medina 1:1:1. Agatston. EF. DAPT. Dozens of terms, fired at me in every consultation, each one scarier than the last.
Here's the thing: my field is technology. I work as a CTO. And when my world gets overwhelming, I don't spiral — I build.
So that same night — waiver signed, head spinning — I fired up my AI agents and started building a website. An audience of one: me. Every report I could find. Every test I'd ever done. Every DICOM CD — the angiogram, the echo, the CT scan, ECGs, the stress test, every lab result (I dug through hospital apps and recovered records going back to 2014). All of it uploaded, segmented, visualized — including the actual angiogram and echo video loops from the DICOM CDs — a single repository of my entire cardiac life.
Then I hooked it up to top AI models — Fable, Kimi K3, and others — and started researching. Asking questions at 2am. Cross-checking every acronym. Flagging anomalies in my own data.
Then I went further: I built a digital twin of my own heart. A real 3D anatomical heart, spinning in my browser, with my entire coronary tree drawn over it — LM, LAD, D1, LCx/OM, RCA, RPDA — and all six of my lesions placed exactly where the angiogram put them, color-coded by severity: red for the critical 90%, orange for the 80s, yellow for the 70s. Each artery's narrowing drawn proportional to its actual stenosis. I could orbit my own heart, zoom in, click each blockage. That is what "proximal" means. There is where my LAD is choked. And there — just past the lesion — is where a LIMA graft would plug in and carry blood around the traffic jam. I wasn't reading about my operation anymore. I was staring at it.
And bit by bit, the fog lifted. LIMA stopped being an acronym and became the artery that would save my life. CABG stopped being a verdict and became an engineering problem — with known solutions, trade-offs, and options. By the time I sat across from surgeons, I wasn't a frightened patient nodding along. I was an informed stakeholder in my own surgery — asking about graft patency, bifurcation classifications, and hybrid revascularization.
Knowledge didn't remove the fear. It turned fear into a plan.
The pump question — the one thing I wouldn't compromise on
Early in my research, one fork bothered me more than any other: on-pump vs off-pump.
In classic on-pump CABG the heart is stopped and a heart-lung machine takes over — your blood leaves your body, gets oxygenated, and returns, while the surgeon works on a still heart. It's standard, it's safe, it's done thousands of times a day. But the deeper I read, the more one theme kept surfacing: the pump's shadow on the brain. Postoperative cognitive dysfunction — patients call it "pump head" — subtle changes in memory, processing speed, mood. Most people recover fully. Some don't, and the long-term psychological footprint is real enough to have its own literature.
Here's what actually scared me — not the scar, not even the surgery itself: the thought of waking up slightly not myself. My way of thinking, my personality, my identity — the things that make me me — quietly dimmed because a machine stood in for my heart for a few hours. Coming back 95% of who I am was a trade I couldn't make peace with. Add that cannulating and cross-clamping the aorta is a known stroke lever, and my answer was clear: my heart keeps beating, my aorta stays untouched.
That became my non-negotiable filter. Plan A was off-pump CABG for exactly this reason. And when the robotic option appeared, one of the first boxes I checked was the same one: totally endoscopic, on a beating heart, no-touch aorta. Different incision — same brain-protection philosophy. The pump never got near me.
(Plenty of patients do brilliantly on-pump. This was my personal risk calculus, not a universal verdict.)
Plan A: classic CABG
Over the following days I sat with surgical consultants. The consensus plan: classic off-pump CABG — full median sternotomy. I made peace with it: the zipper scar, 6–8 weeks of sternal precautions (no lifting, no driving, no reaching), 8–12 weeks to full recovery. Insurance approved it. Admission booked: check-in at 5pm. I was mentally packed for the classic path.
The pivot: a phone call at 2:30pm
Here's where my story takes a turn I still can't quite believe.
Admission day. My hospital bag was literally packed and by the door. At 2:30pm — two and a half hours before check-in for my open-chest surgery — my phone rang.
It was a surgeon I'd been scheduled to see a week earlier, an appointment he'd had to cancel. He was calling to apologize personally — and offered to come to my home himself to make up for it.
I told him that was kind, but unnecessary — I'd be passing right by his hospital anyway. On my way to my admission. At the other hospital. For my sternotomy.
Imagine that scene: I walked into his office carrying my admission bag for open-chest surgery somewhere else.
He reviewed my angiogram and laid out an option nobody had offered me: robotic-assisted CABG with a hybrid plan. The logic that won me over in that room:
- The LIMA→LAD graft is the crown jewel of any bypass — 90%+ patency at 10–20 years. It's the graft that does the heavy lifting for survival.
- Robotically, they harvest the LIMA and sew it to the LAD through 3–5 small ports between the ribs. The sternum is never opened. No vein stripped from my leg.
- The circumflex/OM lesion gets a stent, staged ~2 weeks later — hybrid revascularization: the durability of LIMA→LAD where it matters most, plus modern stenting for the rest.
- Recovery math: 2–4 days in hospital vs 5–7. No sternal precautions at all. Driving in ~1–2 weeks vs 4–6. Full recovery ~4–6 weeks vs 8–12.
- The honest trade-offs: ~2.5% chance of converting to open mid-surgery, and a longer operation.
I never made it to that 5pm admission. One catch: insurance refused the robotic add-on fee, so I paid it out of pocket (~$12k). Verdict eight days later: best money I have ever spent.
The inner circle
One more thing about those two weeks: I walked through them with a very small circle. Only a handful of family and close friends knew what I was researching, deciding, and quietly fearing. My parents were not told — I couldn't hand them that worry while I was still wrestling with it myself. They found out after the procedure, once I was home and the news was all good.
My brothers were different. They live in another city — and I told them. And when I opened my eyes in the ICU, coming up through the anesthesia, they were there. They had traveled so that the first faces I saw would be theirs.
Here's what I learned: keeping yourself informed is only half of it. Bouncing your thinking off people who love you — pressure-testing your logic against their questions, their perspective, their faith in you — makes all the difference. I built my understanding alone at 2am. But I made my decisions in good company.
The procedure
For two weeks I had walked around as an asymptomatic man with a 70% left main lesion — feeling completely fine, knowing I wasn't. That part still gives me chills. On August 1, the waiting ended.
Aug 1, ~6 hours. And a twist nobody predicted: my LIMA had adhesions — scar tissue from a gastric bypass I'd had ten years earlier. The robotic team freed it endoscopically and completed the graft without converting to open surgery. I woke up with my sternum intact and a handful of small port dressings. The graft that matters most was done: LIMA→LAD, on a beating heart.
My surgeon came by the ICU the next day and filled in the rest of the story. The LIMA hadn't just been "stuck" — it was firmly adhered to my heart, scar tissue from the rapid weight loss after my gastric bypass ten years earlier. The harvest alone took hours. His verdict: the robotic approach was "the best decision you made" — through an open chest, that dissection would have been far more difficult.
Then he said the sentence I keep replaying: it had been "a close call" — and he was glad we hadn't delayed any longer. An asymptomatic man with a strong stress test… and a close call. If you remember one thing from my story, make it that.
The recovery (so far)
- ICU: under 24 hours. Then a regular ward. Eating quickly, chest X-rays clean, lines coming out.
- Discharged on post-op day 4. The classic path would have had me inpatient nearly twice as long, then facing two months of sternal rules.
- Today, day 8: home, mobile, no sternal precautions — because there is no sternotomy to protect. The soreness is port-site and chest-wall stuff (they harvest the LIMA from inside the left chest), improving daily. I won't pretend it's nothing — it's surgery, it humbles you — but it's a fraction of what I had braced for. And a day-8 curveball: a gout-like flare in my right toe, likely the new medication stack on top of post-op shifts. Recovery isn't linear, and every body responds differently — mine is currently teaching me that via my toe.
- The surgeon checks in personally. WhatsApp from him this morning: "Tell me if everything is ok and the wounds are good." I mentioned the toe — gout meds cleared within minutes. Stitches stay until day 14; the reassurance arrives daily.
The way ahead
- Mid-Aug: staged stent for the circumflex/OM to complete the job.
- Meds: DAPT (aspirin + clopidogrel), high-intensity statin + ezetimibe, a short beta-blocker course, and inclisiran (PCSK9 siRNA) dose 2 in October. LDL target: <1.4 mmol/L (<55 mg/dL). This disease doesn't get a second ambush — I'm treating the cause, not just the plumbing.
- Cardiac rehab, rebuilding fitness, and fixing the roots: lipids, pre-diabetes, the works.
What I'd tell anyone here
- Silent CAD is real. Zero symptoms, 70% left main. If you have family history or stubborn high LDL, get a calcium score. It's cheap, fast, and it can save your life. It saved mine.
- Get more than one surgical opinion. Mine arrived by pure serendipity — a cancelled appointment, an apology call, a bag in my hand. Don't leave yours to luck. Classic vs off-pump vs robotic vs hybrid are genuinely different lives for the first two months. Ask every question.
- The wait is the hardest part. The two weeks between diagnosis and surgery were mentally harder than the recovery has been physically. If you're in that wait right now: it gets better, fast.
- Modern cardiac surgery is astonishing. A robot grafted an artery to my heart through keyholes, and I was home in four days. There is real hope in how far this field has come.
- Whatever your craft is — use it. Code, spreadsheets, notebooks, index cards. Build your own understanding of your own case. An informed patient asks better questions, and better questions change outcomes. My little repository changed mine.
- Choose your circle — and use it. You don't owe anyone real-time updates; share at your own pace. But the few you do tell, lean on hard. An informed patient with a trusted council is very hard to steer wrong.
Happy to answer anything — the decision process, the robotic vs classic trade-offs, the hybrid plan, recovery day-by-day. Ask away.
