FROM THE CATHETER LAB TO PREVENTION
Heart. Brain.
Healthspan.
Stay well and age strong — whether you’re carrying extra weight, watching your blood pressure or blood sugar, living with a heart condition, or simply intent on avoiding all of them. Four pillars, one framework, from a cardiologist who spent thirty years treating heart disease and now teaches how to prevent it.
Not a diet. Not just for heart patients. A cardiologist’s framework for adding healthy, active years — and it matters as much if you’re carrying excess weight as if you’re not.

Consultant Cardiologist · ~30 years invasive practice (NHS, 1991–2021) · Director, Surrey Cardiovascular Clinic
THE PREMISE
After thirty years performing thousands of angioplasties, I realised I was treating the symptoms — not the cause.
For fifty years, medicine named the enemies of the heart it could see — high cholesterol, high blood pressure, smoking — and built the tools to beat them: statins, blood-pressure treatment, the long campaign against tobacco. Cardiovascular death roughly halved. It is one of the great victories of modern medicine.But while we were winning that war, a new enemy grew unopposed. Visceral fat — the metabolically active fat around the liver, pancreas and heart — opened new fronts: atrial fibrillation, heart failure, type 2 diabetes and, on current evidence, dementia. And it quietly reopened the old one, reshaping LDL into small, dense particles and inflaming the artery wall — so the cholesterol number can read normal while the particle count that matters, ApoB, stays high. It is a large part of why heart attacks still strike people whose LDL “looked fine.” It never showed on a standard blood test; it hid behind a normal weight. So it was never named — and what is never named is never fought. This series names it, and hands you the tools to dismantle it. Because the lesson of the last fifty years is simple: once you can see the enemy and measure it, you can beat it.
Make something complicated simple — but no simpler than the truth allows.
A statin does one job well — it lowers your risk of a heart attack. Reducing the fat around your organs does what statins cannot: it protects your heart rhythm, your heart muscle, your metabolism and, the evidence increasingly suggests, your brain. No prescription required
CLINICAL INSIGHTS
What Dr Leatham discovered
Six insights drawn from clinical practice and international literature. The first three form the framework; the second three follow it into muscle, sugar and the brain. Each links to a deeper exploration on the journal.
01
Three risk factors were never the whole story
For decades, prevention chased the visible risks — cholesterol, blood pressure, smoking. They still matter. But they never explained why so many patients with acceptable numbers still developed disease. The missing pieces — blood sugar, and the visceral fat driving it — were never on the standard blood test.
02
Visceral fat is the missing fourth pillar
Belly fat — the “dad bod,” the middle-age spread — is not cosmetic. Visceral adipose tissue (VAT) is metabolically active, produces inflammatory cytokines, and ties together insulin resistance, fatty liver, and silent coronary artery disease. It has been hiding in plain sight, and it is modifiable. The book series focuses on the metabolic and societal reasons for the VAT TRAP that affects millions of people, and how to escape it
03
A statin does one job. Your heart needs four
Statins are a genuine success — but they do one job: they lower the risk of a heart attack. They do little for the conditions rising fastest in later life — atrial fibrillation, heart failure, type 2 diabetes and, on current evidence, dementia. Those share one upstream driver: visceral fat — the fourth pillar. Acting on all four pillars — blood pressure, cholesterol, glucose and visceral fat — addresses the biology beneath them, and each reinforces the others.
06
What's good for the heart is good for the brain
The four pillars do not only protect the coronary arteries. Vascular health, glycaemic control, muscle mass, and lower systemic inflammation all map onto reduced dementia risk and better cognitive aging. Healthspan — not just lifespan — is what the framework is really about.

THE BOOK SERIES
Five short books. One framework.
Books 2, 3 and 4 are practical playbooks you can read or skim in an hour or two. Book 1 is the theory; Book 5 is the cardiologist's own story — both take a little longer. Each book stands alone; together they form a roadmap.
An N-of-1 Companion workbook accompanies Books 2 and 3.
