Mitral valve function disorders
The mitral valve is a very important elementcardiovascular system of a person. In this regard, any deviation in its functioning negatively affects our health and well-being. We suggest to know about the appointment of the mitral valve, as well as about possible violations in its work, their symptoms and consequences. I also want to note that, if there are any signs that the work of this "detail" of the heart muscle is violated, it is necessary to visit the cardiologist, which will help to diagnose a possible disease at an early stage.
Function of the mitral valve in the operation of the human heart muscle
The valve is a leaf of a specialconnective tissue and is located in the left side of the human heart. It prevents the reverse flow of blood entering the left atrium from the left ventricle during a constant contraction of the myocardium. When the heart is completely healthy, the valve, passing the required amount of blood, closes. If the valves begin to close tightly, the heart is stretched and hypertrophied, which eventually leads to disturbances in its work. Most often in this area there are such diseases as mitral valve tightening (or prolapse) and its insufficiency. We propose to elaborate on each of these violations in the work of the heart muscle.
Prolapse
The prolapse of the mitral valve, which isa consequence of condensation, occurs quite often. The disease, as a rule, is asymptomatic. However, it happens that it is accompanied by shortness of breath, pain and palpitation of the heart.
There are several factors that increase the risk of prolapse. These include the reasons described below.
- Floor. In men, this disease is detected much more often than in the representatives of the beautiful half of humanity.
- Age. The risk of developing mitral prolapse increases significantly with age.
- Family history. If one of your relatives has suffered from such a disease, then the likelihood of its occurrence also increases.
- Structural anomalies (congenital or acquired changes).
Mitral insufficiency
There are two forms of mitral insufficiencyvalve: acute and chronic. The first arises from the defeat of papillary muscles, surgical operations, ruptures of tendon chords due to myocardial infarction, infective endocarditis and various traumas. Chronic form can be the result of rheumatic damage to the heart muscle, systemic diseases, hereditary or congenital ailments, tumors and other conditions.
The easiest stage of the disease isinsufficiency of mitral valve 1 degree. The main manifestation of an ailment is the appearance of noises in the heart. As a rule, patients lead an active life and have no complaints. With mitral insufficiency of the second or third degree to the noise in the heart, dyspnea and heart rate increase during physical exertion are added. The most dangerous for human life are the 4th and 5th stages, when dystrophic changes in the heart muscle begin to occur, and the functioning of other organs worsens as a result of circulatory disorders.
