An overview of High Blood Pressure, or Hypertension. Blood pressure refers to the pressure that the blood in under when it moves through the arteries. A normal BP is less than 120/80. High blood pressure is frequently called "the silent killer", since there are rarely symptoms associated with it. Hypertension is a risk factor in blindness, stroke, heart attack, kidney failure, and poor circulation. Hardening of the arteries and too much salt can worsen blood pressure.
