As spokesman for Lipitor, I have been an advocate of preventive medicine in addition to my work with the Jarvik 2000 Heart, which has rescued people from death and sustained a patient with a normal, mobile lifestyle for seven and a half years - the longest in the world.

The artificial heart is very effective as a bridge to transplant, but the number of people that can be saved with human hearts is limited. A perfect artificial heart could save many more patients.

As a medical doctor who chose a career in artificial heart technology rather than clinical practice, I decided not to take an internship, which is required for licensing. Instead, I work with invention, manufacturing, regulatory affairs, and clinical application of artificial hearts.

Lipitor is one of the most researched medicines. I'm glad I take Lipitor, as a doctor, and a dad.

I am a medical scientist, not a practical physician.

I knew that my father was going to die of heart disease, and I was trying to make a heart for him.

I am, in fact, a medical doctor; I am a world expert in mechanical heart technology; and I am an athletically fit man who takes care of his own health through diet and exercise, including frequent five mile runs.
