Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
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.
In addition to orthostatic hypotension, supine hypertension, where the BP is excessively high lying down, is a frequent problem in multiple system atrophy. Treatment of one symptom can easily aggravate the other, and supine hypertension in such patients has been linked to the same cardiovascular complications as essential hypertension .
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
Aortic pressure, also called central aortic blood pressure, or central blood pressure, is the blood pressure at the root of the aorta. Elevated aortic pressure has been found to be a more accurate predictor of both cardiovascular events and mortality, as well as structural changes in the heart, than has peripheral blood pressure (such as ...
About half of hypertension cases in middle-age and older adults are shared or “concordant” within couples, a new study suggests, meaning if one spouse has high blood pressure, their partner ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
