Blood pressure, also known as blood pressure or blood pressure, is the pressure exerted by blood against the wall of arteries, the blood vessels that carry blood from the heart to the various organs and tissues of the body.
Blood pressure is measured in two components:systolic pressure: popularly known as “high pressure” or “upper”. It corresponds to the blood pressure caused by ventricular systole, which is the contraction of the heart that causes blood to flow through the arteries. 120 mmHg is considered the ideal value, although it is considered normal between 110-130 in young adults and up to 150 in middle age and depending on the patient’s circumstances. diastolic pressure: popularly known as “low pressure” or “lower”. Corresponds to blood pressure during ventricular diastole. A value of 60 mmHg is considered ideal, and up to 90-100 mmHg can be accepted as normal, depending on age.
Blood pressure is usually measured in the arms, preferably in the left arm which is the arm that receives the pumping from the heart more directly. To measure blood pressure correctly, the part of the arm being measured must be relaxed and at the level of the heart.
Blood pressure values on the right arm they are usually slightly lower than on the left arm, but only a few points. Nevertheless, monitoring of blood pressure in both arms is recommended, especially in patients at cardiovascular risk. Very different measurements, of 10 or more points of difference between the two arms, can reveal heart diseases that have not yet shown symptoms.
Some studies give figures of up to a 38% increased risk of heart attacks and other serious cardiovascular problems in patients with large differences in blood pressure readings between their left and right arms.
These differences may be due to underlying issues that have not manifested themselves. For example, the difference in blood pressure between the two arms could be due to blockage of blood flow by oppressive structures, blockage by atherosclerosis, peripheral vascular problems, and other conditions of the cardiovascular system that can affect blood pressure differently in each arm.
Therefore, blood pressure should preferably be measured on the left arm and compare with readings on the right arm, which can provide useful information in preventing cardiovascular risk.
