**Who This Book Is For:**

This book is for anyone who has ever been told their cholesterol is too high and prescribed a statin without a deeper conversation. It is for readers who sense that the standard story about heart disease does not quite add up. It is for people who want to understand the actual mechanisms of cardiovascular disease and take meaningful action to protect their health. If you have ever wondered why heart disease remains a leading killer despite decades of cholesterol-lowering treatments, this book will change how you think.

For more than half a century, we have been told a simple story about heart disease. The story goes like this: cholesterol in the blood, particularly LDL cholesterol, seeps into artery walls. Over time, it accumulates. Eventually, it blocks the artery. A heart attack follows. Lower your cholesterol, the story continues, and you lower your risk. This story has shaped medical practice, dietary guidelines, pharmaceutical development, and public health policy for generations. It has sold billions of dollars worth of statins and low-fat foods. It has changed what people eat, what doctors prescribe, and what researchers study. It has become so deeply embedded in our collective understanding that questioning it is often treated as heresy. There is just one problem. The story is wrong. Malcolm Kendrick, a Scottish physician with decades of clinical experience, has spent years examining the evidence behind the cholesterol hypothesis. What he found was not a solid scientific foundation but a house of cards built on misinterpreted studies, circular reasoning, and industrial influence. In *The Clot Thickens*, he dismantles the cholesterol hypothesis piece by piece and offers a different explanation for what actually causes heart disease. The alternative explanation is not new. In fact, it predates the cholesterol hypothesis by nearly a century. In the 1850s, the Austrian pathologist Karl von Rokitansky proposed that atherosclerotic plaques were the result of blood clots that formed on damaged artery walls and were then incorporated into the vessel. He called this the encrustation hypothesis. It was a compelling idea, grounded in direct observation of diseased arteries. But it was pushed aside as the cholesterol hypothesis gained momentum in the mid-twentieth century. Kendrick argues that Rokitansky was essentially right. Heart disease begins not with cholesterol but…
