High Blood Pressure

Frequently Asked Questions

4. What is isolated systolic hypertension?

About two out of every three people over the age of 60 who have high blood pressure have isolated systolic hypertension. This means that only the top number, the systolic pressure, is high -- 140 mmHg or higher. Isolated systolic hypertension can be as harmful as when both numbers are high.

You may have isolated systolic hypertension and feel fine. As with other types of high blood pressure, it often causes no symptoms.
