A lot of the diagnosis and monitoring functions will be done through little devices - smartphones - by the patient with computer assistance. So it's a real big change in the model of how we render healthcare.

I use a portable pocket ultrasound device instead of a stethoscope to listen to the heart, and I share it with the patient in real time. 'Look at your valve, look at your heart-muscle strength.' So they're looking at it with me. Normally a patient is tested by an ultrasonographer who is not allowed to tell them anything.

The ability to diagnose an imminent heart attack has long been considered the holy grail of cardiovascular medicine.

Medicine is still all about treating populations, not people - one-size-fits all treatments and diagnoses.

About half of all people don't take medications like they're supposed to.

The stethoscope for listening to the heart is over. It's obsolete.

Medicine is incredibly ritualistic.
