      It can sneak up on you or can become a life-long problem. High blood pressure comes in many forms.

      â??There are a billion people in the world that have hypertension high blood pressure," David L. Brown, MD, Director of Interventional Cardiology and Co-Director of CV Research at The Heart Hospital Baylor Plano in Plano, Texas, told Ivanhoe.

      Fact or fiction: You need to monitor both arms when measuring blood pressure.

      Fact: A British study found differences in blood pressure between left and right arms could increase the risk of death.

      Fact or fiction: Leaving the table salt on the table lowers your risk.

      Fiction: Not necessarily! Up to 75 percent of the sodium you consume is hidden in processed foods, so check your labels, too.
