abnormally high arterial blood pressure that is usually indicated by an adult systolic blood pressure of 140 mm Hg or greater or a diastolic blood pressure of 90 mm Hg or greater, is chiefly of unknown cause but may be attributable to a preexisting condition (as a renal or endocrine disorder), that typically results in a thickening and inelasticity of arterial walls andhypertrophyof the left heart ventricle, and that is a risk factor for various pathological conditions or events (as heart attack, heart failure, stroke, end-stage renal disease, or retinal hemorrhage), seisund, mille korral suure vereringe suurte arterite vererõhk on pidevalt kõrgem normaalsest ja esineb risk haigestuda ateroskleroosi, südamepuudulikkusesse ning ajuvereringe ja neerutalituse puuete tekkeks
