NEW YORK – Former Vice President Dick Cheney, one of the world's most prominent heart patients, is working on a book about his many battles with coronary disease and the revolutionary changes in treatment that helped keep him alive.

The 71-year-old Cheney is collaborating with his cardiologist, Dr. Jonathan Reiner, and with his daughter, Liz Cheney. Scribner, an imprint of Simon & Schuster, announced Monday that the book is scheduled for next fall. It is currently untitled.

"It explains and talks about all the developments in cardiology by going through my own case," the former vice president said Monday during a brief telephone interview. "I'm alive today because of the tremendous advances that have been made."
