A Personal Story of Reversal

From five blockages to a world record

Peter Megdal, Phd

Biopharmaceutical scientist · Nutrition PhD · Competitive cyclist · Heart disease survivor

Diagnosed with inoperable coronary blockages at 55. Three years later: zero ischemia on stress testing, VO₂ Max up 20%, and on the path to the world stage.

Chapter One

The diagnosis no one saw coming

Peter had been a competitive cyclist for 40 years. He ate carefully. He trained hard. And then his power output quietly started to drop — with no explanation.

The First Signal

A 14% drop in cycling power — and no explanation

Peter noticed an abrupt, unexplained 14% reduction in his cycling power output. His coach said it was aging. He trained harder for four years trying to reverse it — with no improvement. Something was wrong that training couldn’t fix.

The Angiogram

Five blockages. Two at 70–90%. Inoperable.

A maximal exercise stress test at Mass General Hospital revealed ST segment depression at 90% of VO₂ Max — a sign of cardiac ischemia. An angiogram followed. The results were severe: three non-obstructive lesions and two obstructive lesions, including a 90% blockage in the right coronary artery. Due to their location, neither stenting nor bypass surgery was feasible. His cardiologist looked at Peter and shrugged.

"The doctor pointed out three or four blockages of 70 and 90 percent and said they were unable to insert a stent or do bypass surgery due to their location. He looked at me and shrugged."

Chapter Two

The research begins

With no surgical options, Peter turned to the medical literature. His PhD gave him access to journals most patients never see. What he found changed everything.

Full-Time Research

Months in the medical literature — a conclusion that surprised him

Peter spent months reading peer-reviewed cardiology journals. His background in biopharmaceuticals and his PhD in nutrition gave him the tools to evaluate the evidence rigorously. The conclusion: aggressive lipid therapy combined with a whole-food plant-based diet had the strongest evidence base for actual plaque regression — not merely slowing progression, but reversal. The work of Dean Ornish, Caldwell Esselstyn, and Colin Campbell formed the dietary foundation.

"The evidence for reversing heart disease pointed to a low-fat whole-food plant-based diet and a short list of cholesterol-lowering drugs. I was stunned. I grew up in Texas."

— Peter Megdal

The Dietary Shift

Total cholesterol drops from 200 to 150 — from diet alone

In March 2015, Peter and his wife eliminated all animal products and added oils. Within months, his bloodwork transformed: total cholesterol fell from 200 to 150 mg/dL, LDL from 140 to 100 mg/dL — before any medication. He then added Repatha (evolocumab), a PCSK9 inhibitor, after statins caused intolerable muscle pain. His LDL ultimately reached 40 mg/dL.

"The doctor pointed out three or four blockages of 70 and 90 percent and said they were unable to insert a stent or do bypass surgery due to their location. He looked at me and shrugged."

Chapter Three

The three-part protocol

Diet alone wasn’t enough. Peter combined aggressive lipid therapy and structured training to create what the published case study calls “optimal medical therapy combined with lifestyle change.”

🥦

Pillar one

Whole-food plant-based diet

Strict elimination of all animal products, added oils, and processed foods. Modeled on the research of Ornish, Esselstyn, and Campbell — ultra-low fat, high fiber, zero dietary cholesterol.

Macros: ~12% fat (95% unsaturated), 75% carbohydrate, 13% protein, 0% dietary cholesterol. No meat, dairy, or fish. No added oils. High-fat plant foods only rarely.

💊

Pillar two

Aggressive lipid therapy

Statins caused intolerable muscle pain and reduced cycling performance. Peter petitioned his cardiologist for Repatha (evolocumab) — a PCSK9 inhibitor that disabled the protein destroying his LDL receptors.

Repatha (evolocumab): A biologic that disables the PCSK9 protein, allowing the liver to remove dramatically more ApoB particles from circulation. Near-zero side effect profile in the literature — and Peter’s experience.

🚴

Pillar three

Structured endurance training

Peter never stopped competing. He maintained elite-level cycling training throughout — improving endothelial function through nitric oxide production and using performance as the objective proof of recovery.

Measurement: VO₂ Max and 20-minute maximal power output used as objective markers throughout. Same tests, same protocol, serial measurement — so progress was real and verifiable.
