In medicine, systolic hypertension is defined as an elevated systolic blood pressure (SBP). [1] If the systolic blood pressure is elevated (>140) with a normal (<90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. [2] Eighty percent of people with systolic hypertension are over the age of 65 years old. [3]
Both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are risk factors. [49] Elevated pulse pressure has been found to be a stronger independent predictor of cardiovascular events, especially in older populations, than has systolic, diastolic, or mean arterial pressure.
The first report of elevated blood pressure in a person without evidence of kidney disease was made by Frederick Akbar Mahomed (1849–1884). [176] Until the 1990s, systolic hypertension was defined as systolic blood pressure of 160 mm Hg or greater. [177] In 1993, the WHO/ISH guidelines defined 140 mmHg as the threshold for hypertension. [178]
Elevated blood pressure occurs when a person has a systolic pressure of 120-129 mmHg (top number) and a diastolic pressure (bottom number) that's lower than 80 mmHg.
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
Orthostatic hypertension involving the systolic BP is known as systolic orthostatic hypertension. High diastolic blood pressure measured while standing in a person who stood up shortly after waking up. When it affects an individual's ability to remain upright, orthostatic hypertension is considered as a form of orthostatic intolerance.
Both of these definitions had collectively been known as malignant hypertension, although this medical term is replaced. [ citation needed ] In the pregnant patient, the definition of hypertensive emergency (likely secondary to pre-eclampsia or eclampsia) is only a blood pressure exceeding 160 mmHg systolic blood pressure or 110 mmHg diastolic ...
Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart.While there are several definitions of hypertensive heart disease in the medical literature, [1] [2] [3] the term is most widely used in the context of the International Classification of Diseases (ICD) coding categories.
