High blood pressure (HBP) also is called hypertension (HI-per-TEN-shun).
When HBP has no known cause, it may be called essential hypertension, primary hypertension, or idiopathic (id-ee-o-PATH-ick) hypertension.
When another condition causes HBP, it's sometimes called secondary high blood pressure or secondary hypertension.
In some cases of HBP, only the systolic blood pressure number is high. This condition is called isolated systolic hypertension (ISH). Many older adults have this condition. ISH can cause as much harm as HBP in which both numbers are too high.

Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. These studies are a key research tool for advancing medical knowledge and patient care. Learn more about clinical trials.
Clinical trials currently are under way for High Blood Pressure. For more information about these studies, visit www.clinicaltrials.gov.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
