Measured in mm Hg (millimeters of mercury)
e.g. 124/82 mm Hg Systolic=124 mm Hg Diastolic= 82 mm Hg

Why Do Some People Develop Heart Disease or Stroke, while Others Don’t?
There are several risks that cause heart attacks and strokes
The more risks and the higher the risks, the greater the chance of developing heart disease or stroke
More than 9 in 10 People with hypertension have other risks of developing heart disease and stroke
