Many times in my career, I’ve given my patients the basics about the causes and risk factors for CHD, which leads to an estimated 735,000 heart attacks per year. And I’ve filled them in on the latest treatment options and lifestyle changes that can improve their health and help them prevent future heart attacks. But like most busy doctors, I don’t always have the time to fully explain everything about CHD and the exciting advances in its treatment. That’s where this book comes in. I wanted to find a way to give my patients and others the detailed information they can use to take charge of their heart health.

This book is intended to help answer the questions I hear on a daily basis in my office. You may have many of these same questions too. Although this book is primarily intended as a resource for patients with CHD, it also serves as a guide for family members and friends who are supporting you through the process. It can help all of you gain a better understanding of CHD and discover things you may want to discuss further with your own doctor to ensure you are doing everything possible to enhance your wellbeing.
