The pressure is increased! Diastolic and systolic pressure - difference in values

Systolic and diastolic pressure are important characteristics of the functioning of the circulatory and cardiovascular systems of the human body. The lower indicator - diastolic pressure - indicates the value of this parameter at the time of relaxation (diastole) of the heart. Systolic pressure corresponds to the moment of blood supply to the artery (systole) and is the upper number of blood pressure.

Unfortunately, many people of younger age have lower pressure (diastolic value). The reason for this is notorious stress, negative emotions, the impact of external factors. During such events, the speed of blood circulation increases and, accordingly, the pressure on the arteries. Its value depends on the degree of permeability of peripheral arteries, the elasticity of their walls and the frequency of pulsations.

Optimal is the ratio of the upper and lower blood pressure values - 120/80 mm Hg. Art. For each person, due to his physiological characteristics, these figures may vary slightly. Exceeding their value above 140/90 mm Hg. Art. Is considered the onset of hypertension. At the same time, the risk of diseases such as myocardial infarction and stroke increases. The difference in systolic and diastolic pressure is considered normal at a value of 30-40 units. This difference is called pulse pressure.

Increased diastolic pressure

Temporary increase in the lower pressure in certain situations does not pose a particular danger. If the pressure is increased (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. A 20% increase in the risk of myocardial infarction and a 30% stroke.

High lower pressure can arise due to diseases of the kidneys, adrenals, endocrine organs, heart disease, as well as the formation of tumors in the body. With a decrease in blood flow, the kidneys produce the renin substance, which is biologically active. The tonus of muscles of the arteries increases, the result - the pressure is increased. Diastolic pressure in this regard is sometimes called renal.

But these are only common causes of abnormal lower pressure, other factors influence its index. To clarify the true nature of the phenomenon, it is necessary to undergo a survey that includes the study of the hormonal background, biochemical analyzes of urine, blood, and so on.

If the blood pressure values are 120/100 or 130/115 mm Hg, The lower pressure is increased (diastolic) with normal systolic pressure . Such indicators are called isolated diastolic pressure. It is quite dangerous, because the heart in this case is in a prolonged voltage, which leads to a violation of blood flow in his muscle.

As a result, blood vessels lose their elasticity, their permeability is disturbed. If pathological changes in the cardiac 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 medicinal fees for hypotensive and sedative action.

Low diastolic pressure

When the diastolic pressure is lower (less than 60 mm Hg), this can be either a variant of the norm or a pathological phenomenon - hypotension. This, in turn, can result from another chronic disease, allergic process or endocrine pathology.

This indicator of lower pressure occurs in 5% of men and women of middle and even young age and may not affect health in any way. But with a consistently low value, you need to see a doctor. Especially it can be dangerous for pregnant women.
