There are many different causes of high blood pressure. We differentiate between common primary (essential)
hypertension, and secondary hypertension. The latter group can be ascribed to specific organic malfunctions. Please
consult your doctor for information about the possible origins of your own increased blood pressure values.
1.4 Normal Blood Pressure Values
Blood pressure is too high when measuring at home and you have rested, the diastolic pressure is above 85 mmHg or
the systolic blood pressure is above 135 mmHg. If you obtain readings in this range, consult your doctor immediately.
High blood pressure values over time can damage blood vessels, vital organs such as the kidney, and your heart.
With blood pressure values that are too low (i.e., systolic values under 105 mmHg or diastolic values under 60 mmHg),
consult with your doctor.

Note: A diagnosis of high blood pressure must be confirmed with a medical professional. A doctor should
evaluate any unusual blood pressure readings. Additionally, lower targets may be appropriate for some
populations such as African-Americans, the elderly, or patients with underlying issues such as diabetes
mellitus or chronic kidney disease.
Important for Canadians:
* Hypertension measured at home ≥ 135/85
* Hypertension measured at a physician’s office ≥ 140/90
* Hypertension measured at a physician’s office for a diabetic patient ≥ 130/80
