We've got a conversation about "white coat syndrome" here. This is when your blood pressure is normal at home, but at a doctor's appointment it scales. People are not allowed to work or are not hired for surgery. It can be very annoying.
We have already disassembled home blood pressure measurement rules. It is not necessary to attach a complex automatic monitor to yourself. Sometimes enough information can be obtained by self-measuring blood pressure twice a day.
People measure blood pressure at home, bring these results to a cardiologist, who then pokes his finger in the record and says that everything is bad. This is because when measuring at home, the pressure will not be considered to be 140/90 millimeters of mercury, but 130/80, for example. Is it a shame? Yes, it's a shame. This is all due to statistics.
The fact is that no one knows exactly which pressure hurts people. Well, that is, we use Korotkov tones in a mechanical tonometer or other clever methods of measuring blood pressure, but usually we do not literally climb inside the blood vessels.
Serious statistical data on the connection of blood pressure with all sorts of strokes or heart attacks have been accumulating for 70 years. And in most cases, people came to the doctor, he measured their blood pressure, and then after many years they calculated which of these people had a heart attack.
It is clear that many people freaked out at the doctor's appointment, and the pressure was too high. Gradually, over the decades, statistics accumulated, and it might seem that heart attacks, roughly speaking, more often happen to those with blood pressure above 140/90. But these were the so-called "office measurements" in the doctor's office. The pressure there was to some extent overstated. Therefore, it can be assumed that heart attacks with strokes happened more often with those whose real pressure was not 140/90, but lower. Maybe 130/80. Got it?
The point is not in the exact figures of pressure, but in those cherished 140/90 millimeters of mercury, which were intended for heart attackers 40 years ago with a mercury tonometer.
Once again. All these 70 years the pressure was measured slightly incorrectly, so if now you have measured it perfectly, then to you requirements will be tougher. And the increased pressure can be called 130/80.
