Isolated systolic high blood pressure
In isolated systolic high blood pressure (isolated systolic hypertension, or ISH), systolic blood pressure is elevated (above 140 mm Hg), but diastolic blood pressure stays below 90 mm Hg. This type of high blood pressure is more common in older adults, especially older women. In fact, the majority of people older than 60 who have hypertension have isolated systolic hypertension.
If you are older than 50, a systolic blood pressure over 140 mm Hg is an important risk factor for stroke and heart disease.
ISH can cause damage to organs such as the kidneys, brain, heart, or eyes, and it should be treated.
Treatment of ISH often begins with the use of a diuretic, which seems to be effective in older people. Other medicines that may be used include long-acting calcium channel blockers, beta-blockers, or angiotensin-converting enzyme (ACE) inhibitors.
The Dietary Approaches to Stop Hypertension (DASH) diet is effective for treating isolated systolic hypertension.
