This book is a must for anyone who has a history of cardio problems in their family or are experiencing problems of their own. In fact, if you aren't sure, you need to read this book anyway. I learned more about my heart, various tests and results than I would ever have imagined in this short and concise book. I am not a doctor and all the details and test results seem to blur for me. In this book Dr. Warrick provides cases and outlines test results compared to what would be ideal. I can now use this book as a guide when I review my results. More importantly though is that Dr. Warrick lays out a path to using CT scans to proactively prevent heart attacks rather than just treating the disease after you have one. Ironically, after I started reading this book, I developed a (non-heart) medical issue based on traditional medical test results in which a CT scan was used to further determine whether there was an actual issue. If works for one part of the body, why not for cardio as well? This is a great read presented in a very easy to understand format. I am grateful for having had the opportunity to read this book. It is a great reference book to have on hand.
