NEW YORK (AP) - Former Vice President Dick Cheney is working on a book about his battles with heart 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.
Cheney worked with his daughter on his memoir "In My Time," which came out in 2011.
