The researchers found that the models could predict blood pressure with a measurement bias of 0.39 [+ or -] 7.30 mm Hg, −0.20 [+ or -] 6.00 mm Hg, and 0.52 [+ or -] 6.42 mm Hg for systolic pressure, diastolic pressure
, and pulse pressure, respectively.
Decades of research have indicated that high systolic blood pressure is more likely than diastolic pressure
to predict heart disease, but now, a new study finds that both numbers in blood pressure readings have a strong association with heart attack and stroke risk.
But those risks also climbed in tandem with diastolic pressure
; and people with normal systolic readings were still at risk if their diastolic pressure
They assessed hypertension according to the 2017 ACC/AHA high blood pressure guideline, which defined Stage 1 hypertension as having systolic blood pressure between 130-139 or diastolic pressure
between 80-89, and Stage 2 hypertension as having systolic pressure above 140 or diastolic pressure
The mean age, BMI, ACR, systolic, diastolic pressure
and height (cm) of the two genders are given in table-I.
While it is generally considered to be more important than diastolic pressure
, both readings have their use.
In 2003, a panel appointed to the Seventh Joint National Committee (JNC7) defined hypertension as a systolic blood pressure of 140 mmHg or higher or a diastolic pressure
of 90 mmHg or higher.
Blood pressure is recorded with two numbers representing the systolic pressure and diastolic pressure
It is measured in millimetres of mercury (mmHg) and is given as two figures: Systolic pressure - the pressure when your heart pushes blood out Diastolic pressure
- the pressure when your heart rests between beats.
The researchers found that systolic pressure was nearly 23MMHG lower after 30 minutes than it was in a one-off reading, and the diastolic pressure
was nearly 12MMHG lower than the one-off mean diastolic pressure
The first Korotkoff sound indicated systolic pressure and fifth Korotkoff sound indicated the diastolic pressure
. This was recorded as the basal BP.
Aortic out flow, coronary effluent, cardiac output, dP/dt(max), dP/dt(min), systolic and diastolic pressure
, heart rate, and aortic pressure were measured.
