We have been able to narrow the gap between the systolic and diastolic pressures
, and we look forward to confirming these results in the SAPPHIRE trial.
A 7-day average of prior pulmonary-artery diastolic pressures
was calculated for each patient every day, and this reference value was applied to each day's new pressure readings.
Systolic pressure occurs when the heart is contracted and the diastolic pressure
occurs when the heart is relaxed.
Hypertension involves an elevation of the blood pressure where systolic blood pressure is above 140 mm Hg, diastolic blood pressure is above 90 mm Hg, or a systolic and diastolic pressure
of 20 mm Hg is above normal baseline pressure.
The subgroup of diabetic patients had the lowest rates of control, with systolic pressure controlled in 56% and diastolic pressure
controlled in 63% of patients.
Physicians have previously focused on reducing diastolic blood pressure of patients with hypertension; however, there is mounting evidence that systolic blood pressure is as important as diastolic pressure
in predicting cardiovascular disease risks.
In contrast, for in-office measurements at baseline, every 10-mm Hg increase in systolic blood pressure raised the risk of the combined end points by 18%, and each 10-mm Hg increase in diastolic pressure
raised the risk by 11%.
While physicians have previously focused primarily on reducing diastolic blood pressure in patients with hypertension, there is mounting evidence that lowering systolic blood pressure is as important, if not more important, than lowering diastolic pressure
The drug significantly improved a number of indices of left ventricular function in patients with impaired resting heart function (left ventricular end diastolic pressure
, LVEDP greater than/equal to 12mmHg, n=30) but had less effect in patients with normal resting heart function (LVEDP less than/equal to 12mmHg, n=17).
A similar analysis for diastolic pressure
showed that patients who maintained their average pressure below 80 mm Hg had a 66% reduced risk of developing AF, said Dr.
More than 70 million people in the United States have hypertension, which is considered systolic pressure above 140 and diastolic pressure
They continue to release the pressure until they, once again, no longer hear the heart beating - this is the bottom number of blood pressure, known as diastolic pressure
(80-90 or below).
The systolic pressure is the pressure exerted in the arteries when the ventricles are contracted during a heartbeat; the diastolic pressure
is the pressure exerted in the arteries when the ventricles are fully open during a heartbeat.
The US Centers for Disease Control (CDC) considers normal a systolic pressure of less than 120 mm Hg and a diastolic pressure
of less than 80 mmHg.
After two months, systolic blood pressure dropped by an impressive 7 points and diastolic pressure
fell by 5 points in the freeze-dried-blueberry eaters, but neither budged in those who got the imitation blueberry.
