The difference between systolic and diastolic blood pressure is called pulse pressure (PD). Not many people know that deviations from the norm of this indicator are dangerous. A significant deviation from the normal range may signal disturbances in the functioning of the myocardium and problems in the vascular permeability. Deviations from the norm adversely affect the work of the whole human body, but the kidneys suffer the most.
The normal value of the pulse pressure ranges from 30 to 50 mm Hg. Art. Low PD signals any malfunction of the heart. In this condition, the patient experiences anxiety, decreases visual acuity, and in some cases paralysis of the respiratory system occurs. Critically low rate – 20 mm Hg. Art.
A high degree of rigidity of the aorta is the main cause of high PD in humans. Such a manifestation often occurs against the background of atherosclerosis and hypertension. High pulse pressure often worries older people with coronary heart disease and those who have had heart attacks or strokes. It is necessary to consider in more detail the causes of these states.
What is pulse pressure?
Normally, the difference between systolic and diastolic pressure – PD – should be 40 mm. Hg Art., deviations of 10 more or less, as a rule, do not signal major changes in the body. Young and healthy people have no problems with these indicators. Pathology develops in people of mature age, this is due to the aging of blood vessels.
It is important to note that high values (over 60 units) in elderly people indicate a serious change in the cardiovascular system.. A similar problem should be addressed to a cardiologist and immediately begin treatment.
The change in this indicator is influenced by the use of antihypertensive drugs. Often, after taking medications, hypertensive patients note that only diastolic pressure is reduced, while systolic blood pressure remains the same, hence the small difference between them.
Value above normal
In a healthy person, the pulse pressure increases at the time of considerable physical exertion, and then decreases quite quickly. This is not inconvenient and not dangerous.
Among the causes of this violation can be identified:
- chronic heart failure;
- high intracranial pressure;
- ischemic heart disease.
Such a deviation is often observed in pregnant women. This is due to the fact that all the organs of the expectant mother, including the heart, are working in intense mode. Iron-deficiency and problems in the thyroid gland can act as a provoking factor. To identify the causes should be examined, timely diagnosis will avoid the development of pathologies.
Low pulse pressure
Pulse pressure is considered extremely low if it is less than 25% of the systolic value. With a long course of the pathological process, atrophic changes in the brain structure occur, vision is disturbed, many manifestations arise from the nervous system.
Pathology is rapidly developing in the background:
- heart valve stenosis;
- vegetative-vascular dystonia;
As a rule, the patient complains of constant weakness and dizziness. A person in such a state cannot concentrate and do work.
What are dangerous deviations from the norm?
Any deviations from the norm are dangerous to human health and violate the integrity of the body as a single system. When conducting a full examination of a patient with similar complaints, in most cases the following diseases and abnormalities are detected:
- Stenosis of the mouth of the aorta. This leads to a decrease in the amount of blood that the heart throws out.
- Myogenic dilatation of the heart.
- Ischemic condition of the kidneys.
- Vasoconstriction, a significant slowdown in blood circulation.
The formation of these pathologies is a long process. Therefore, a timely request for medical care guarantees recovery. To do this, you must undergo a full diagnosis and therapy.
For the timely diagnosis of diseases of the cardiovascular system, it is necessary to measure pressure indicators 2 times a day. The measurement must be performed using a tonometer, in the home it is convenient to use new electronic devices.
To normalize the values of pulse pressure it is useful to perform light breathing exercises and use tonic preparations. Among these tools can be identified tincture of hawthorn and ginseng. However, you should not use these drugs without the appointment of a cardiologist. Self-medication can lead to irreversible consequences up to cardiac arrest.
