High blood pressure, also called hypertension, is by far the most potent risk factor for stroke. People with high blood pressure have a risk for stroke that is four to six times higher than the risk for those without high blood pressure. Also, 40 to 90 percent of stroke patients have high blood pressure before their stroke event.
If your blood pressure is high, you and your doctor will need to work out an individual strategy to bring it down to the normal range. Ways to lower blood pressure include:
Maintaining a healthy weight
Avoiding drugs known to raise blood pressure
Cutting down on salt
Eating fruits and vegetables to increase potassium in your diet
