Definition (MEDLINEPLUS)

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure.

Your blood pressure reading uses these two numbers, the systolic and diastolic pressures. Usually they are written one above or before the other. A reading of

  • 119/79 or lower is normal blood pressure
  • 140/90 or higher is high blood pressure
  • Between 120 and 139 for the top number, or between 80 and 89 for the bottom number is prehypertension

High blood pressure usually has no symptoms, but it can cause serious problems such as stroke, heart failure, heart attack and kidney failure. You can control high blood pressure through healthy lifestyle habits and taking medicines, if needed.

NIH: National Heart, Lung, and Blood Institute

Definition (NCI_CDISC) Pathological increase in blood pressure defined as one of the following: History of hypertension diagnosed and treated with medication, diet, and/or exercise; On at least 2 separate occasions, documented blood pressure greater than 140 mm Hg systolic and/or 90 mm Hg diastolic in patients without diabetes or chronic kidney disease, or blood pressure greater than 130 mm Hg systolic or 80 mm Hg diastolic in patients with diabetes or chronic kidney disease; Currently on pharmacological therapy for the treatment of hypertension.
Definition (NCI) Blood pressure that is abnormally high.
Definition (NCI_CTCAE) A disorder characterized by a pathological increase in blood pressure; a repeatedly elevation in the blood pressure exceeding 140 over 90 mm Hg.
Definition (NCI_NCI-GLOSS) A blood pressure of 140/90 or higher. High blood pressure usually has no symptoms. It can harm the arteries and cause an increase in the risk of stroke, heart attack, kidney failure, and blindness.
Definition (CSP) persistantly high arterial blood pressure.
Definition (MSH) Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
