Heart murmur calls for redoubled care with bacterial infections
Breath is the name of a noise that can be heard ("auscultated" in technical terms) on the physical examination. The murmur in the heart is the result of blood passing through a smaller hole than it should. It sounds like the sound of someone blowing in your ear (the narrow place that generates the noise is the ear canal) or a crack in the open window.
The blow happens when some heart valve (we have four) has a reduced through-hole (stenosis) or when it does not close right and let the blood come back through a hole (insufficiency). According to the severity of the stenosis or insufficiency the heart begins to accumulate unpumped blood in the lungs and liver. Because of this, the organ grows in size to try to "push the blood" harder. This measure resolves in the medium term, but then the symptoms of heart failure settle and the shortness of air becomes constant.
The person may be born congenitally, or present with advanced age, due to the degeneration of some valve. It can also occur as a sequela of endocarditis or after myocardial infarction, due to valve or heart muscle damage. Sometimes the heart murmur is functional, as in cases of fever and hyperdynamic states, and it disappears when the cause of acceleration of the blood is corrected. In the analogy of the window, the crack makes noise only when it is sold, but not when there is a light breeze.
Any suspicion should follow an appointment with a doctor first. Usually an electrocardiogram (ECG) and an echocardiogram solve the doubts. Thus it is possible to decide whether the treatment is surgical or only follow-up. Even today, it is possible to operate by catheterization instead of open chest! In most cases it is no longer necessary to open the chest.
Some patients with a breath need to take antibiotics before doing dental treatments and minor surgeries. This is why a diseased valve can harbor gum bacteria that fall into the bloodstream during manipulation or tooth brushing!
If in doubt, schedule a medical appointment and discuss the type of problem, risks, and benefits of your treatments .
The ACL prevents the tibia, located bone, in the cinnamon from sliding forward of the thigh. Dr. Martha Murray is responsible for developing this innovative way to repair ACL and stabilize the knee. The method involves inserting a protein sponge between the ruptured ligament. The patient's blood is placed inside this protein sponge to form a clot.
