Flint explains that previous research has influenced cardiology guidelines, which have focused primarily on
systolic pressure to predict the risk of heart disease.
In the latest study, cardiovascular risks rose with each "unit increase" in
systolic pressure above 140, by about 18% on average.
The study's findings also showed that, in one measure of cognitive function, the serial reaction time task, the patients treated to a
systolic pressure of 130 mm Hg had an average 23-millisecond improvement in their reaction time from baseline to their 3-year follow-up, while patients in the control group treated to a
systolic pressure of 145 mm Hg had a 33-millisecond increase in their average reaction time during follow-up.
Patients with a single episode of
systolic pressure lower than or equal to 110mmHg during the one-year period were twice as likely to experience a serious fall or faint.
Patients with a single episode of
systolic pressure lower than or equal to 110mmHg during the one-year period were twice as likely to experience a serious fall or faint and patients who had an average systolic blood pressure lower than 110mmHg over the one-year study period had a 50 percent greater risk of serious falls and fainting than those who had an average systolic blood pressure higher than 110mmHg.
Comparison between Systolic Blood Pressure measured by Oscillometry method (BPO) and by Pulse Oximetry method--Average of
systolic pressure measured by reappearance and disappearance of pulse oximetry waveform (AvgSP--Average
systolic pressure).
Blood pressure is recorded with two numbers representing the
systolic pressure and diastolic pressure.
Recent evidence has suggested that while people in general benefit from a systolic blood pressure of 120 mm Hg or less, older adults might fare better with a higher
systolic pressure. But this latest study found that lower
systolic pressure was best for seniors.
When they start to hear the heart beat again, this is the top number of blood pressure, known as
systolic pressure (120-140 or above).
Mean right ventricular
systolic pressure (RVSP) pre PTMC was significantly higher 62.3+-10.91 mm of Hg than that of post PTMC 24 hour's 57.51+-9.67 mm of Hg and post PTMC 06 moths 46.49+-7.8mm of Hg, p value 0.001.
The first Korotkoff sound indicated
systolic pressure and fifth Korotkoff sound indicated the diastolic pressure.
Similarly, MADs were associated with a significant 2.1 mm Hg reduction in
systolic pressure and 1.9 mm-Hg reduction in diastolic pressure, compared with inactive controls.
