	MedlinePlus Medical Encyclopedia: Blood pressure
		Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through the body.
		The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries.
		Blood pressure is usually measured while you are seated with your arm resting on a table.

	Understanding how blood pressure works
		Blood pressure, the force of the blood pushing against the walls of the arteries, is expressed as a fraction.
		The systolic pressure (top number) is the pressure of blood in the vessels when the heart contracts; diastolic pressure (bottom number) is the pressure of the blood between heartbeats when the heart is at rest.
		Systolic blood pressure (the higher number) is the maximum force exerted against blood vessel walls each time the heart beats, while diastolic blood pressure (the lower number) is the force exerted on the blood vessels when the heart is resting between beats (Zaret, Moser and Cohen, 1992).

	DHDSP - About High Blood Pressure
		High blood pressure or hypertension for adults is defined as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher.
		Prehypertension is defined as a systolic blood pressure of 120–139 mmHg or a diastolic blood pressure of 80–89 mmHg.
		Reduced blood to the heart muscle can lead to angina (chest pain or damage to the heart muscle due to a lack of blood carrying oxygen to the heart muscle) or to a heart attack (caused by a chronic spasm or blockage of blood and oxygen to the heart).

	BLOOD PRESSURE: SYSTOLIC, DIASTOLIC, MEAN, PERFUSION
		Blood pressure is a measurement of the force applied against the walls of the arteries as the heart pumps blood through the body.
		Blood pressure readings are usually given as two numbers: for example, 110 over 70 (written as 110/70).
		The second number (the lower number) is called the "diastolic blood pressure" reading, and it represents the pressure in the arteries when the heart is at rest.

	Systolic blood pressure predicts mortality in heart failure patients
		Systolic blood pressure, a readily available vital sign taken at hospital admission, has been found to be a key factor in predicting mortality risk and revealing important disease characteristics for heart failure patients, according to a team of academic researchers.
		Systolic blood pressure demonstrates the maximum arterial pressure during contraction of the left ventricle of the heart -- typically the first number in a blood pressure reading (for example, 120 mm Hg when the blood pressure is reported as 120/80 mm Hg -- measured in millimeters of mercury).
		Researchers note that systolic blood pressure may be an indicator of the stage of heart failure with lower systolic blood pressures indicating more advanced disease and prognosis.

	Blood Pressure, Systolic Blood Pressue, Diastolic Blood Pressure, Normal Blood Pressure
		Blood pressure is the pressure produced when your heart pumps blood into the arteries of the body.
		Your blood needs to be under pressure to move it forward so that the arteries can carry it to the organs, tissues and cells of the body (arteries carry blood away from the heart, veins generally carry blood towards the heart).
		Recently however, some studies have suggested systolic blood pressure is important too, and it is now generally agreed that 'systolic hypertension' (a series of readings in which systolic blood pressure is found to be raised most of the time, diastolic being normal) should be treated.

	Clinical Advisory: NHLBI Issues New Clinical Advisory on Systolic Blood Pressure
		The cornerstone of the campaign is the release by the NHLBI and the NHBPEP of a clinical advisory recommending that systolic blood pressure be emphasized in the diagnosis and treatment of hypertension in middle-aged and older adults.
		Blood pressure is typically recorded as two numbers-the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats).
		Blood pressure should be reduced carefully in elderly persons with longstanding severe systolic hypertension; for resistant patients, blood pressure goals may take longer to reach.

	UB Reporter: Systolic pressure linked to stroke
		People with only mildly elevated systolic blood pressure have a high risk of stroke similar to those with significantly raised systolic or diastolic blood pressure, long-term follow-up of a large national population sample has shown.
		This study suggested that mild elevations in systolic blood pressure in the range of 140 to 159 mm Hg also increase the risk of stroke and its subtypes, although to a smaller magnitude, and that the risk pertains even to people in their 40s.
		Analyzing stroke events with baseline blood pressure readings and other variables, researchers found that participants who had isolated systolic hypertension at baseline were nearly three times more likely to have had any kind of stroke than participants with normal blood pressure.

		Systolic pressure, which is the higher number and first number in a blood pressure reading, measures the force of blood in the arteries as the heart contracts to push blood through the body.
		Researchers from Johns Hopkins studied the effects of high systolic and diastolic blood pressure simultaneously and found a direct and consistent correlation between increased systolic blood pressure and an increased risk of death from cardiovascular disease and for all other causes among all of the study participants.
		Additionally, many people with high blood pressure are overweight, so don't be fooled--make sure that you or your doctor uses an appropriate size cuff that is large enough for your arm.

		Systolic blood pressure, the maximum arterial pressure during contraction of the left ventricle of the heart, is an important factor in predicting mortality risk for heart failure patients.
		Systolic blood pressure is typically the first number in a blood pressure reading; for example, 120 when the blood pressure is reported as 120/80.
		For many younger patients, a low blood pressure is a sign of heart health, but for some older patients and heart failure patients, who need a higher blood pressure to maintain adequate blood flow to vital organs, low blood pressure can be a sign of serious problems.

	Re: Regarding Diastolic and Systolic blood pressure
		With regards to the change in pressure with exercise, it is not uusual for the systolic pressure to rise 10 to 20 mm of mercury during strenuous exercise.
		This is the pressure in the system while the heart contracts - the heart pumps faster, and pumps a greater volume of blood during exercise.
		Blood pressures average in the area of 120/80 +/- 10mm for children ages 10 to 12.

	Postgraduate Medicine: Hypertension Symposium: Controlling isolated systolic hypertension
		The goal was to reduce systolic pressure to less than 160 mm Hg in those with initial readings of more than 180 mm Hg and to reduce the systolic pressure by 20 mm Hg in those with initial readings between 160 and 180 mm Hg.
		In pseudohypertension, cuff measurements of blood pressure underestimate the systolic pressure and overestimate the diastolic pressure.
		Some preliminary data suggest that blood pressure measurements in the fingers are accurate in patients with pseudohypertension, because these arterioles are not as prone to atherosclerosis as the larger arteries, such as the brachial artery, which is used to auscultate the Korotkoff sounds (25).
