If your blood pressure is even slightly over normal, you may be at greater risk of a stroke.

120 over 80 is considered ideal. For anything higher than 140 over 90, your doctor may prescribe medication.

If the number is just a little over normal, you have what's called "pre-high blood pressure."

Until now, doctors haven't been concerned about it. But researchers in China revisited past studies involving nearly 800,000 people and found those with pre-high blood pressure were 66 percent more likely to suffer a stroke.

What can you do? Consume less salt and exercise more.
