Pseudohypertension is caused by atherosclerosis, and the cuff does not easily block blood flow during measurement, so it must continue to inflate to increase the pressure, at which point the mercury column also rises, and the blood pressure value thus measured is not the true blood pressure value. When we say blood pressure, we mean the blood pressure value obtained by indirect measurement from outside the body with a sphygmomanometer, which requires applying pressure on a limb (brachial artery of the upper arm) through a balloon to block the blood flow, then deflating it and listening to the arterial pulsation sound, and the systolic pressure when the arterial pulsation sound is heard, and the diastolic pressure when the arterial pulsation sound disappears. If the arterial wall is hardened to the point of being like a hard rubber tube, it is not easy to block the blood flow with normal pressure, but only with very high pressure to flatten the tube and block the blood flow. In recent years, it has been confirmed that some elderly patients with high blood pressure measured indirectly, such as measured by the direct method are normal, such “hypertension” is called pseudohypertension. So does pseudohypertension not need to be treated and left alone? In fact, no, we all know that the treatment of hypertension is only to reduce hypertension caused by a variety of cardiovascular events, and pseudohypertension is an indication of atherosclerosis, because atherosclerosis is caused by hyperlipidemia, hyperglycemia, obesity, and advanced age and other factors. Although you do not need to take antihypertensive drugs, but to lower blood lipids, lose weight, as well as eliminate mental tension, etc., in order to slow down the process of atherosclerosis, so as to avoid the occurrence of true hypertension, and reduce the occurrence of cardiovascular and cerebrovascular events, this is the real way of health care for the elderly!
