Systolic
blood pressure is a measure of how much pressure your heart is exerting against your artery walls when your heart is beating.
"Our results suggest that one's
blood pressure during midlife may influence how
blood pressure later in life relates to dementia risk.
Understanding these numbers is the key to controlling
blood pressure. The systolic pressure shows how much pressure the blood places on the arteries when the heart beats, while the diastolic
blood pressure shows the pressure while the heart is resting between beats.
High
blood pressure - or hypertension - doesn't usually have any symptoms and, if untreated, can increase the risk of serious problems such as heart attacks and strokes.
This insight led some doctors to adopt a
blood pressure philosophy of "the lower, the better."Successive guidelines have since decreased the recommended threshold for what constitutes high
blood pressure, from 160/95 millimetres' of mercury in 1973, to 140/90 in 1997, to 130/80 in 2017.Still, the question remained: How low should
blood pressure go?A decade long study that began in 1972 provided a clue.
When
blood pressure is high, the blood moves through the arteries more forcefully.
New research being presented at the American College of Cardiology's 68th Annual Scientific Session found that people who took advantage of a midday snooze were more likely to have a noticeable drop in
blood pressure compared with those who didn't nap.
If you take
blood pressure medication, you should be monitoring your
blood pressure at home.
- Kaiser Permanente research published in the American Journal of Preventive Medicine found if patients with hypertension taking prescribed medications experience unusually low
blood pressures -- systolic
blood pressure under 110mmHg -- they are twice as likely to experience a fall or faint as patients whose treated
blood pressure remains 110mmHg and above.
Researchers also found a link between higher
blood pressure and Alzheimer's.
Study author Zoe Arvanitakis said, '
Blood pressure changes with aging and disease, so we wanted to see what kind of impact it may have on the brain.'
More than one in four adults in the UK have high
blood pressure, or hypertension, according to the NHS.
High
blood pressure is a common condition in which the long-term force of the blood against the artery walls is high enough that it may eventually cause health problems, such as heart disease.
RAISED
blood pressure is the number-one contributing risk factor for death worldwide.
