In my experience with my wife's congestive heart failure for the past three months I have come to the conclusion there are very few doctors that think outside of the box. They still believe what they learned in medical school whether it was 40 years ago or 10 years ago. They dismiss anything they have not learned in general. The exception are a few doctors who are always striving to learn about the new research whether it be in herbs, vitamins (especially D 3) or technology. I am very disapointed in medical care in general.
