Prehypertension. Prehypertension, also known as high normal blood pressure and borderline hypertensive ( BH ), [ 1] is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension (high blood pressure). Prehypertension is now referred to as "elevated blood ...
35094-2. Blood pressure ( BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11] High blood pressure usually does not cause symptoms itself. [ 1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
New research suggests even just a bump of 10 mmHg over normal levels of systolic blood pressure can increase risk of stroke by 20%. "We combined six studies that have followed participants over ...
Women who have high blood pressure and had complications in their pregnancy have three times the risk of developing cardiovascular disease compared to women with normal blood pressure who had no complications in pregnancy. [37] [38] Coronary heart diseases are 2 to 5 times more common among middle-aged men than women. [33]
Pulse pressure is the difference between systolic and diastolic blood pressure. [ 1] It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. Healthy pulse pressure is around 40 mmHg. [ 1][ 2] A pulse pressure that is consistently 60 mmHg or greater is likely to be associated with ...
Lactase persistence or lactose tolerance is the continued activity of the lactase enzyme in adulthood, allowing the digestion of lactose in milk. In most mammals, the activity of the enzyme is dramatically reduced after weaning. [ 1] In some human populations though, lactase persistence has recently evolved [ 2] as an adaptation to the ...
Flowchart showing baroreceptor reflex. The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms that helps to maintain blood pressure at nearly constant levels. The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure causes the heart rate to decrease. Decreased blood pressure decreases ...
