Low heart pressure: causes and consequences
Usually people are very afraid of hypertension, as it entails the development of serious pathological conditions – strokes, heart attacks, etc. But low blood pressure is also a reason to think about your health and to consult a doctor, especially if we are talking about systolic pressure or heart.
Blood pressure is always characterized by two numbers, for example 120/80 (measured in mm Hg. calendar). The top figure shows the blood pressure in vessels during a heart contraction and ejection of blood into the aorta (systole), so this indicator is also called the systolic or heart. The bottom number is the blood pressure in the arteries at the moments full of relaxation of the heart (diastole), it is created by the resistance vessels, respectively, and is called the diastolic or vascular.
In normal healthy person’s pressure should fluctuate within the following limits (in mm Hg. calendar): top – 100 – 130, the lower – 60 – 90. These figures may deviate to one side or the other for 5 – 10 units, the most desired is considered the indicator of 120/80 mm Hg. article About low blood pressure (hypotension) say that if your systolic (heart) the pressure drops to 90, and diastolic – 60 mm Hg and below. St. That is, a person with indicators tonometer 89 60 can be safely diagnose low heart pressure. Will look at why there is such a state?
Causes of low heart pressure
Reduced systolic blood pressure in young people and athletes, not having any complaints is often the norm and requires only periodic check-UPS with your General practitioner or cardiologist. When hypotension is accompanied by severe symptoms (e.g., dizziness, headaches, blurred vision, nausea, fatigue and other), you should definitely look for reasons for these pathological changes.
Hypertension in the past now?
Cardiologists risk to remain without work — hypertension now curable!
Etiological factors contributing to the decline in systolic pressure, there may be different condition in which the heart contracts with insufficient force (no sufficient ejection of blood into the vessels). This occurs in severe heart diseases, myocardial infarction, cardiomyopathy, heart failure and other cardiac diseases.
In addition, they suffer serious bleeding, dehydration, i.e., the pathological States leading to a decrease in the volume of circulating blood in the blood stream. Systolic blood pressure also falls in the excessive expansion of vessels, for example, in shock (septic, anaphylactic, etc.).
It is also worth remembering that systolic hypotension may develop on the background of the use of certain drugs: beta-blockers, antidepressants, drugs for Parkinson’s disease, etc. After discontinuation of these drugs, the patients usually returns to normal.
In women, low heart pressure is often associated with the peculiarities of a hormonal background (in particular, an excess of estrogen), and alteration of the organism in the period of carrying a child. The increase in vasculature (due to the growing uterus and placenta) in the body of a pregnant woman leads to slightly drop and the systolic and diastolic pressure.
In addition, a common reason of hypotension in women (men – less) is a neurocirculatory dystonia. To cause a decrease in heart pressure endocrine disorders, neuroses, stress, brain injury and other pathological effects on the Central nervous system centers that regulate heart activity and vascular tone. Thus, the list of possible causes of systolic hypotension is very extensive, so people with a similar problem should be carefully examined and diverse.
The severity of low cardiac pressure, primarily determined by the severity of hypotension. The lower the pressure, the slower the blood flows to tissues and organs, accordingly, they late get essential nutrients and most importantly oxygen. Faster than anyone of hypoxia begin to suffer brain and heart muscle, i.e. these bodies are the primary targets of hypotension.
It is also worth considering the fact that the deterioration of blood supply of the CNS is almost always manifested by dizziness, fainting, falls and serious injuries. Therefore, hypotension can indirectly cause a concussion, fractures, etc.
«I have cured hypertension, You can too!»
Actor Oleg Tabakov said
In conclusion, it should be noted that hypotension is not such a high risk of strokes and heart attacks, which is the place to be for hypertension. However, low pressure almost always carries poor health, poor performance and a noticeable deterioration in the quality of life of the patient.
