Lower pressure: why it is important and how to keep under control

The most famous heart study has been going on for more than 70 years and has been observing the third generation of Framingham residents. It proves that high systolic blood pressure is a sure sign of a future heart attack or stroke. But is that second digit on the blood pressure monitor so insignificant?

In 2019, more than one million adults were studied and it was found that a high “Bottom” blood pressure also contributes to the prognosis for cardiovascular catastrophe. It turned out that a second digit above 80 mmHg increases the risk of heart attack and stroke over the next eight years almost as much as high “Upper” blood pressure readings.

Recall what each index is responsible for. Systolic pressure – This is the force with which oxygenated blood is pushed out of the heart and through the body. Diastolic – This is the pressure of the blood against the walls of the blood vessels at the moment when the heart fills up and rests between beats.

Pressure norms were revised in 2017, and today numbers above 119/79 are already considered the beginning of hypertension. It turns out that the ideal blood pressure is between 90/60 and 120/80.

While systolic blood pressure increases with age, diastolic blood pressure usually rises before the age of 50 and then has the opposite effect. “Upper” blood pressure rises during emotional distress, sports, or after coffee and a cigarette. The heart starts beating more frequently and spurting blood – so at the moment of systole, the first digit on the blood pressure monitor rises.

As long as your blood vessels remain healthy and elastic, your blood pressure stays within the normal range between heartbeats. Once the capillaries become stiff and narrow, there is little room for blood. It strengthens the vessels on the walls, even as it flows quietly as the heart relaxes – so the diastolic rate rises.

A single rise in blood pressure in response to stress or physical exertion is not considered a disease. But if the values above the norm are held for several weeks, it is time to sound the alarm. Hypertension can occur either separately, only systolic or only diastolic, or simultaneously by two indicators.

The condition is especially dangerous when the difference between the upper and lower blood pressure becomes minimal. This is called pulse pressure, and normally it is about 35-50 mmHg. For example, when your blood pressure is 120/80, your pulse rate will be 40 (120 minus 80). In some situations, the pressure during heart contraction approaches the values at the moment of relaxation. For example, when fluid accumulates in the chest and the heart does not have enough “acceleration” for the pump to work at full force. Blood does not flow to distant areas and there is a risk of brain damage due to oxygen deprivation.

Accumulation of fluid in the pericardium is an extraordinary event. However, approaching “Lower” pressure to “Upper” pressure can include isolated diastolic hypertension. Sometimes it is due to kidney or thyroid involvement, but in most cases the cause cannot be identified. It is certainly known that high diastolic pressure with normal systolic pressure is more common in young people under 40-45 years of age, especially if they are overweight.

Fortunately, elevated “lower” blood pressure alone is not as strongly associated with the risk of cardiovascular outcomes as it is with total or isolated systolic hypertension. The bad news is that after high “Lower” numbers for 10 years, the “Upper” blood pressure almost certainly rises as well.

Pills, isolated hypertension, don’t always help. Medication lowers both the upper and lower numbers, and a blood pressure that is too low, less than 90/60, threatens the same oxygen trust. The good news is that as long as there are no other problems than high numbers on the blood pressure monitor, non-drug therapy can save the day. It includes diet and 150 minutes a week of moderate cardio exercise.

Any hypertension can run without symptoms and be an accidental finding at the next examination. That there are no changes in the heart, kidneys and retina, and, therefore, it is possible to cast high blood pressure without pills, will only tell the doctor. For this purpose, urine and blood tests are taken, an ultrasound of the heart, an ECG and an examination of the eye fundus are carried out. Even if the doctor decides that you can not do without medication, remember that it is better to live actively “on pills” than to be proud of them in the absence of a trainer in the cardiac intensive care unit.
