Be in the Know: Hypertension Facts
If you think you or someone else may be experiencing a stroke, call 911 immediately. Do not drive to the hospital.
What Is Hypertension?
Hypertension, or high blood pressure, is one of the most significant and controllable risk factors for stroke. It occurs when the force of blood against artery walls is consistently too high -- typically defined as a reading of 130/80 mmHg or higher. Often called the "silent killer," hypertension frequently has no symptoms until serious damage has already occurred.
Hypertension and Stroke Risk
High blood pressure is the leading cause of stroke. It can damage blood vessels over time, making them more likely to rupture or become blocked. People with hypertension are up to four times more likely to have a stroke than those with normal blood pressure. Managing blood pressure through lifestyle changes and medication can dramatically reduce that risk.
Know Your Numbers
Regular blood pressure monitoring is essential. Normal blood pressure is below 120/80 mmHg. Elevated readings (120–129 systolic) and Stage 1 hypertension (130–139/80–89 mmHg) are warning signs that require attention. Stage 2 hypertension (140+/90+ mmHg) requires immediate medical intervention. Talk to your doctor about your numbers and what they mean for your stroke risk.
What You Can Do
Lifestyle changes can make a significant difference: reduce sodium intake, maintain a healthy weight, exercise regularly, limit alcohol, quit smoking, and manage stress. Work with your healthcare provider to develop a personalized plan. If medication is prescribed, take it as directed -- and never stop without consulting your doctor.
