Could measuring a risk factor for heart disease be as easy as a touch of the finger?
Researchers at the University of Iowa have found that the pulse in your finger, along with your body mass index and age, could be a reliable indicator of the stiffness of your aorta, which is the artery that goes out from the heart to deliver blood to the body.
When the aorta becomes stiff, the heart needs to work harder -- which could lead to higher blood pressure and even heart attack risk.
