High blood pressure, or hypertension, is a major risk factor for stroke. A new study has found that sustained elevated systolic blood pressure (the top number in a blood pressure reading) over a long period of time significantly increases the risk of stroke, even among people who do not have other traditional risk factors for stroke, such as high cholesterol or diabetes.
Key Findings
- People with sustained elevated systolic blood pressure (140 mm Hg or higher) for 10 years or more had a 63% higher risk of stroke compared to those with normal blood pressure.
- The risk of stroke was even higher (89%) among people who had sustained elevated systolic blood pressure for 20 years or more.
- The risk of stroke was independent of other traditional risk factors for stroke, such as high cholesterol or diabetes.
Implications
These findings suggest that sustained elevated systolic blood pressure is a major risk factor for stroke, even among people who do not have other traditional risk factors for stroke. This highlights the importance of regular blood pressure monitoring and control for all adults, regardless of their age or other health conditions.
Recommendations
To reduce the risk of stroke, it is important to keep blood pressure under control. This can be done through lifestyle changes, such as:
- Eating a healthy diet with plenty of fruits, vegetables, and whole grains
- Losing weight if overweight or obese
- Getting regular physical activity
- Quitting smoking
- Limiting alcohol intake
If lifestyle changes are not enough to lower blood pressure, medication may be necessary. People with sustained elevated systolic blood pressure should talk to their doctor about a treatment plan that is right for them.
Conclusion
Sustained elevated systolic blood pressure is a major risk factor for stroke. It is important for all adults to have their blood pressure checked regularly and to make lifestyle changes or take medication to keep blood pressure under control.
