high blood pressure

see hypertension.  

A repeatedly elevated blood pressure exceeding 140 over 90 mmHg. High blood pressure (hypertension) is "the silent killer." Chronic high blood pressure can stealthily cause blood vessel changes in the back of the eye (retina), abnormal thickening of the heart muscle, kidney failure, and brain damage. No specific cause for high blood pressure is found in 95% of patients. High blood pressure is treated with salt restriction, regular aerobic exercise, and medications.

An arterial condition whose primary feature is chronically elevated blood pressure.
