Systolic and diastolic pressure are important characteristics of the circulatory and cardiovascular systems of the human body. The lower indicator - diastolic pressure - indicates the value of this parameter at the moment of relaxation (diastole) of the heart. Systolic pressure corresponds to the moment when blood flows into the artery (systole) and is the upper number of blood pressure.
Unfortunately, many people of an increasingly young age have elevated lower blood pressure (diastolic value). The reason for this is the notorious stress, negative emotions, the impact of external factors. During such phenomena, the rate of blood circulation increases and, accordingly, the pressure on the arteries. Its value depends on the degree of patency of the peripheral arteries, the elasticity of their walls and the frequency of pulsations.
The ratio of the upper and lower values of blood pressure is considered optimal - 120/80 mm Hg. Art. For each person, due to his physiological characteristics, these figures may vary slightly. Exceeding their value over 140/90 mm Hg. Art. considered the beginning of arterial hypertension. Whereinincreases the risk of diseases such as myocardial infarction and stroke. The difference between systolic and diastolic pressure is considered normal at a value of 30-40 units. This difference is called pulse pressure.
Elevated diastolic blood pressure
Temporary increase in lower pressure in certain situations is not particularly dangerous. If the pressure is elevated (diastolic) and does not decrease for a long time, it is necessary to be examined by specialists. With a stable increase in this indicator by 5 mm Hg. Art. 20% increased risk of myocardial infarction and 30% increased risk of stroke.
High lower pressure can occur due to diseases of the kidneys, adrenal glands, endocrine organs, heart disease, as well as the formation of a tumor in the body. With a decrease in blood flow, the kidneys produce the substance renin, which is biologically active. The tone of the muscles of the arteries increases, the result is increased pressure. Diastolic pressure is therefore sometimes referred to as renal pressure.
But these are only common causes of abnormal lower pressure, other factors also influence its indicator. To find out the true nature of the phenomenon, it is necessary to undergo an examination, including the study of hormonal levels, biochemical analyzes of urine, blood, and so on.
If the blood pressure values are 120/100 or 130/115 mm Hg. Art., then the lower pressure is increased (diastolic) with normal systolic. Such indicators are called isolated diastolic pressure. Itquite dangerous, since the heart in this case is in prolonged tension, which leads to impaired blood flow in its muscle.
As a result, blood vessels lose their elasticity, their permeability is disturbed. If pathological changes in the heart muscle become irreversible, this leads to the formation of blood clots.
After identifying the nature of the disease, specialists should prescribe appropriate medications that can be combined with the use of antihypertensive and sedative drugs.
Low diastolic blood pressure
When diastolic pressure is low (less than 60 mmHg), it can be both a normal variant and a pathological phenomenon - hypotension. This, in turn, may be the result of another chronic disease, allergic process or endocrine pathology.
This indicator of lower pressure is found in 5% of men and women of middle and even young age and may not affect he alth in any way. But with a consistently low value, you need to see a doctor. This can be especially dangerous for pregnant women.
