--A change of heart
Today, the prevention of heart disease seems like pure common sense, but it wasn't always so obvious. Sixty years ago, the nation's top cardiologists didn't have a clue about how to save the life of President Franklin D. Roosevelt. His death was one in a growing epidemic of cardiovascular disease that spurred researchers to find answers. In 1948, the Framingham Heart Study was launched, and the lives and deaths of 5,209 volunteers from Framingham, Mass., taught the rest of the world just which behaviors and genetic traits put them at risk. Daniel Levy, a cardiologist specializing in prevention, a faculty member at Boston University School of Medicine and Harvard Medical School, and director of the Framingham Heart Study; and Susan Brink, a senior writer at U.S. News, have written a book, A Change of Heart: How the People of Framingham, Massachusetts, Helped Unravel the Mysteries of Cardiovascular Disease. It begins with an eye-opening reminder of just how far we've come.
FDR's death shows how much we've learned about the heart
