More than three out of five deaths from heart attack occur simply because people don't immediately go to the hospital, waiting instead to see if symptoms persist. Now a pioneer of modern cardiology draws on fifty years of patient care to explain that the majority of heart attacks don't just happen spontaneously but are preceded by early warning signs--including little-known signs that go unrecognized by most people. If people would get proper treatment within the first sixty minutes of symptoms (the Golden Hour), they should suffer little or no damage to heart muscle. Dr. Turner also presents the early warning signs of stroke and instructions on how to respond, as well as what people can do to help prevent the occurrence or recurrence of heart attack and stroke.
