I used to measure my blood pressure with my right hand all the time. Yesterday I accidentally changed my left hand. I found that my blood pressure on both sides was different, 130-80mmhg on the right side and 159-119mmhg on the left side. Is this my hypertension?
Seeing this problem,
I think of a news report I saw before:
Mr. Li, who has just turned 40, has always been aware of paying attention to blood pressure. He often measures his blood pressure and finds that every time he measures his blood pressure, it is within 140 / 90mmHg. He thinks he controls his body well.
Suddenly one day, Mr. Li appeared to speak not clear, at the same time, the right limb obviously no strength and other symptoms, was sent to the hospital by his family found to be acute cerebral infarction.
However, it was found that Mr. Li's blood glucose and blood lipid were normal, his blood pressure was 126 / 76mmhg, and he did not smoke or drink. How could he have acute cerebral infarction?
Later, it was found that Mr. Li always measured his blood pressure on the right side. When the nurse measured his left side, he found that his blood pressure was as high as 170 / 100mmhg, which was the same level several times.
It turns out that Mr. Li's acute cerebral infarction is really caused by high blood pressure!
Why is blood pressure different on both sides?
Generally speaking, due to physiological and anatomical reasons, the blood pressure values measured by the left upper arm and the right upper arm are different, but generally not more than 10 mmHg.
If the difference between the two sides of blood pressure values is relatively large, there are many reasons, such as young people may be caused by multiple Takayasu arteritis or congenital artery malformation; for middle-aged and elderly patients with hypertension, the most common reason is atherosclerotic disease, especially severe subclavian artery stenosis caused by atherosclerotic plaque.
Similarly, the difference of blood pressure in both upper limbs of middle-aged and elderly patients with hypertension may be a marker of systemic atherosclerosis.
Once upon a time, relevant studies in the UK showed that:
The patients with different blood pressure in both upper arms are likely to suffer from vascular diseases,
When the blood pressure difference between the two upper arms was more than 10 mmHg,
The risk of death from vascular disease will increase by 70%,
The risk of death from other diseases will increase by 60%,
So, should blood pressure be "high" or "low"?
Of course, I believe in the "high" blood pressure. In fact, the "low" blood pressure is due to the pathological state which reduces the pressure of the vascular wall. It is morbid and inaccurate.
Higher blood pressure is the closest to real blood pressure. Therefore, when we start to measure blood pressure, we should measure the left upper arm and the right upper arm at the same time, basically confirm which side is high, and the higher side shall prevail in the future.
If it is found that there is a significant difference in blood pressure between the two sides, the doctor should be consulted and further examination should be carried out to determine the cause, and active treatment should be given if necessary.
