Having high blood pressure is a serious problem for the blood vessels because it causes wear and tear on the endothelial cells that line the inside of the blood vessels. Just like a garden hose that’s always under high pressures, in the long-term, blood vessels can develop tiny cracks and tears that can lead to serious problems such as ...
A high blood pressure is present when the resting blood pressure is persistently at, or above, 130 over 80, or 140 over 90 mmHg. [2] [11] It is important to realize, children have much different numbers that depend on their age, and size. [12]
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

The authors defined healthy resting blood pressure as a reading below 130 over 85 millimeters of mercury — a measurement of pressure known as mmHg — pre-high blood pressure as ranging from 130 ...
[18] [19] [needs update] [20] High blood pressure affects 33% of the population globally. [9] About half of all people with high blood pressure do not know that they have it. [9] In 2019, high blood pressure was believed to have been a factor in 19% of all deaths (10.4 million globally). [9] Video summary
“Finding large and sustained blood pressure reductions are important — each mmHg of raised blood pressure raises your chance of a cardiovascular event (heart attack or stroke) by about 2% ...
A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs. Individuals with a history of chronic hypertension may not tolerate a "normal" blood pressure, and can therefore present symptomatically with hypotension , including fatigue ...
Blood pressure varies over longer time periods (months to years) and this variability predicts adverse outcomes. [18] Blood pressure also changes in response to temperature, noise, emotional stress, consumption of food or liquid, dietary factors, physical activity, changes in posture (such as standing-up), drugs, and disease.
