The word is out; high blood pressure has been branded a top public health enemy in the US.

Having high blood pressure makes you at risk for heart disease and stroke. And the problem is that you can have this disease without ever knowing it. If something makes you four times more likely to die of a stroke and three times more likely to die of heart disease, it’s something to take very seriously.
