Why Does Medical Advice Constantly Change? (Video)

How you can keep pace with new research

Why does medical advice constantly change

If you’ve noticed that your cardiologist’s or internist’s advice about how to keep your heart healthy changes over time, you’re not alone. Clinical guidelines are based on the most current evidence-based medicine. So if your doctor tells you at one visit that you need a certain diagnostic test or medication and at the next one tells you that a different one is better, there’s usually a good reason.
