Viewpoint: What will — and won't — change about cardiology in 50 years

Almost nothing that we view as modern cardiology was available 50 years ago. Cardiac procedures and surgery, cardiac intensive care units, almost all cardiovascular medications and even cardiology as a specialty were either unknown or very early in development in the early 1970s. It is likely that cardiology will change as much in the next 50 years as it has in the last 50 years.
