Even slightly high blood pressure may do damage

More than 30 percent of young adults have pre-hypertension. That's blood pressure that is just a little higher than normal.

Until now, this condition wasn't thought to cause big problems. But new research in the Annals of Internal Medicine finds living with even slightly raised blood pressure can take a toll over the long term.

Doctors traced more than 3,500 hundred adults aged 18-to-35. These patients were 22 percent more likely to have hardening of the arteries, raising the odds of heart attack and stroke.

Experts recommend those with even mild high blood pressure take steps to lower their risk, including not smoking, getting more exercise and limiting alcohol intake.
